If it makes you feel any better, I value this video higher than the Tshirt cannon....

This is exactly what a good UKposts channel should be - delivering engaging, non clickbatey content about things viewers didn’t realise were interesting. Thanks Matt.

I work in one of those professional 3D scanner companies in an engineering position. You are the first hobbyist on UKposts that I've seen who said "professional tools are obviously much better but probably not worth it for hobbyists", instead of the "iphone does the same or better, don't bother with professional 3D scanners" which seems to be the consensus. Thank you for being objective and actually taking the time and putting in the effort to form an educated opinion instead of spewing clickbaity garbage.

The shop I'm at got an EinScan for dirt cheap like 2500$ used. To be honest will never mess with a cheap scanner again. Mainly because the details are unmatched and the fact it can scan colors and even can pick up the masking marks from a paint job from 20 years ago.

Happy New Year, Matt! Thanks for all your great content in 2021. Looking forward to another fun, exciting, dangerous year of your projects. All hail the algorithm!

A couple of things that I have considered doing when I get around to scanning something. Make scale markers. These are things that will show up in the scan that are of a precise known size, usually a small cube and a square frame you can place on or around the object. Set up a frame of some sort around and over the object that you can use to steady your hand while scanning. The rafters in a garage might do the trick if you tie a line that you can hold with the scanning hand so you can pan in a stable arc. Turn tables are a must.

I appreciate your content so very much. I find your videos so compelling, not because they are comedic genius but because they are so information dense. You give info how you got the info why you got the info make a quip that makes me chuckle repeat like 50 times and the video is less than 20 minutes long. Any other youtuber conveying as much info as you do would take 45 minutes and would need a part 2.

As always a great video. I love your storytelling with the simple cards with text for the sections in the video. The themed music for certain parts of the video is also amazing.

I like your projects! Never thought of using a scanner. But I KNEW you would present the subject well... so here I am.

Thanks for the comparison. I've been passively interested in scanning kit car bodies and making form-fitting body panels and I learned quite a bit from your video. It's reassuring to know that I don't need a pro scanner for the kind of project I want to do.

The Pop 2 looks like a big improvement on the Pop although it looks like it still has issues with certain surfaces but it comes with stickers and you can use a temporary spray on covering to make scanning easier.

Thank you for the review/comparison. These topics are hard to find and the tech is changing all the time, so, thanks for your time and experience!

One thing that can make your Revopoint work a *lot* better is getting one of those stabilized selfie-stick things. Once I started using one of those, I discovered that the quality of my scans improved dramatically.

FWIW with some surface treatment (developer spray, baby powder, etc) and a decent SLR you can get more detail out of photogrammetry than most pro scanners. Dimensional accuracy depends on the quality of your scale reference but I get very accurate results when I compare caliper measurements to scan dimensions. The point here is to say, there are a lot of middle ground options between phone scan and pro scan tool. Quality becomes less of a differentiating factor and its more about how much effort and time it takes to get your scan result. Processing images in good software like reality capture (expensive) requires a decently powerful computer(also expensive) and a lot of time.

I agree with your point about the scaling problem using photogrammetry but including a ruler in the images resolves this. Would love to see you do a video using meshroom or something similar just to see how it does.

Well, we saw it. We saw the R1000RR engine and now we want the video ASAP. Can we call your new/old car a Bonda? :P

SUPER Excited to see this content. ive been wanting to do this ever since I heard about the lidar tech

The good thing is, people like you buying, using, and giving feedback on things like this,, are paving the road for future products to work better.

Thats a good quality content, I've watched your video entirely without skipping stuff as I did for half of that t-shirt cannon you have mentioned in the end

Happy New Year Matt 👍 Once again an interesting, informative piece about something I’ve not had experience of - thanks 😃

First time a UKposts video answers all my questions and questions I did not know I had. Great info.

4:56 Put a few markers on the extremes of the object, then scale it in software after scanning. You can even average your multiple scaling references to get sub polygon accuracy.

Having taken quite a wild ride attempting to use photogrammetry (meshroom and some other stuff) to do similar stuff to what you're talking about here, I can confirm it's a real rats nest and the part about scaling -- I've run into exactly that issue with it. I'm very happy you did this because of course I'm now targeted with tons of advertising from time to time -- these 3d scanner solutions and I've been dubious about pretty much all of them. Thanks for taking the time to share this -- love your videos man.

I think 3d scanning is really great, and it has alot of applications apart from engineering. its nice to see a comparison between different levels of the tech and if they can make the professional ones cheaper, then i might consider getting a scanner some day.

Just purchased this exact scanner for work. This video made me happy I did. Well done.

"There will be like 8 people who watch this video", has 7.7K likes. Don't underestimate the combination of engineers, fabricators, and 3d printing geeks.

This is why I love your channel, this is exactly the kind of info I was wanting to know but don't have the resources to access. However, I guess that means I'll stick to using an iPhone for scanning since that's what I've got!

Thanks, this totally lines up with my experience of using 3D scanners. Lately I've been trying to work with Meshroom for photogrammetry, and I think if they added good support for CCTags and accelerometer data it should be able to produce good scans with accurate dimensions. I wonder if there's better non-free photogrammetry software out there that would fill the gap...

I actually just used the creality CR-Scan 01 on my car. Sprayed it down with an iso/baby powder mix. It took a long time, but it did really well with the details, it even picked up some of the flaws in the paint.

Happy New Year Matt thank you for last year looking forward to this year

I was positively surprised when i 3d printed a Touch guard for an ABB RCD and just found the whole cad model (at least the outer shell) on their website free to download. Made modelling around it much, much easier

Somehow, you're already 3 steps ahead on everything I've attempted to understand. Thanks for the reassuring conclusion on the state of consumer 3D scanners, I was looking for the missing piece of the market for too long... It's looking like the Revopoint Pop 2 might bring the bar up a bit.

I get the impression that most of this has to do with software. I was trying to use an Occipital Structure scanner (gen 1) a few years back to do interiors of houses for VR tours. The same scanner was more than capable of tracking details, objects, etc.... except when it wasn't (in bad software). Occipital are doing a great job of bringing this stuff to consumers. Cool video, Matt. Thanks for putting it together!

Hey man, great videos! I'm a geomatics engineer with a masters degree in optical metrology, specializing in digital imaging systems. This topic is RIGHT in my wheel house! First, great summary, there's very little I would add in the broad strokes. On the topic of photogrammety, I have mixed feelings. For your use case, its would be _possible_ to get sub-mm 3D models, but I doubt it would be worth your time. To do so, you would need a decent camera with a fixed focal length (i.e. at least a manual focus, no auto focus), you would need to calibrate the camera (it's possible to do that yourself, but it is very finicky, and easy to trick yourself you did a good job), and you would need to some kind of reliable scale reference. For us geos, we would probably use a total station to survey in a couple targets at the extreme extents of the measurement volume. For better results you your scanners, you probably want more "registration features," which could be those white dots, but I personally have used ping ping balls with great success. They're light-weight, highly spherical, a consistent radius, and if you hit them with a bit of matte white, also have consistent illumination across their surface. You could probably hot glue, or even super-glue the on the surface of the engine for you models, then just knock them off when your done. Just be careful not to deform their shape when you glue them, neither through heat, chemistry nor pressure. Also, **until you need to flip you engine over**, adding a nice checker-board pattern to your work bench would greatly improve your feature tracking, with no need for the ping pong balls. It's really important that during a scan, the subject (i.e. the engine) does not move relative to your registration targets (i.e. the check-board or the ping pong balls). You could also put the two together, use the pattern on the bench to scan in each orientation, and use the ping pong balls to register each scan together after you flip it over. Let me know if you have any quetsions. BTW, if you care to read it, I could link you my masters thesis, which features the ping pong balls in chapter 3

T-shirt cannons are for my kids to watch. I’ll watch you for real engineering. Thanks for pulling this together, it’s great to learn where the state of the art is with 3-D capture.

I was literally looking at financing a Peel 1 or 2 scanner, this has made me reconsider...THANK YOU!

I really wish there was an in between. There are a lot of things I've struggled with using iPhone scans and measuring for my Ecoboost swap. I could also convince some buddies to go in on it for their projects as well

Awesome video comparing the pros and cons of the different scan solutions! Subscribed!

Your first 3d scanner video is how i discovered your channel. If only the algorithm showed me earlier.

I use a regular camera and photogrammetry software, and my output is phenomenal and accurate af.

What a great video. To the point, not a bunch of wasted time blabbing on and on lol. I wish all comparison videos were this efficient! All the knowledge right up front the whole time. Exactly what I was looking for. Nice work!

Searched a video like this for ever. Perfect, just perfect.

I use an app called EM3D with my iPhone. I’ve found the measurements it gives me are accurate. Then again I’m using it for clay sculptures and then retopologising to get a less dense mesh. Works for my needs.

Great video! I'm obviously one of the eight people who are very interested in 3D Scanners, but I am also just a tinkerer who doesn't want to pay 10.000 USD or more for a descent scanner. I made about two scans with my Revopoint with one of them being just about usable, but the part was so simple I could have just measured it with calipers and now the scanner is collecting dust. I hope there will be something available soon for around 1.000 USD, that would be great. Please let us know if you find a scanner in that price range.

I look forward to seeing your video on CFD analysis!

We professionally use the Arte Leo scanner. Very expensive (out of the scope of what you mention in the video (garage work) But gets the job done without problems. With a bit of experience, it never loses track of where you are, and even when it does it easily finds it back soon enough. In software later on you can manually stitch together parts of the same scan, but the "automatic stitching" of the software works so well that we never do it manually. Last but not least we never use markers, and we can even scan black surfaces. Have a look online, borrow one (or ask for a demonstration). It worths the video -review if you have the chance.

Greatly appreciate the insight you’ve provided, thank you.

Thanks so much for this great video! I was struggling to find concise info on 3D scanners and this answered all my questions in < 10 minutes :)

This is Fantastic. The iPhone LiDAR Scanner is incredible!

Man this is a great topic. I have been wondering this for years.

One advantage of using an actual digital camera is that you have a broad choice of lenses and the sensor is ***MUCH*** larger. I used CHDK on a Canon running a custom script to automatically create focus-stacked, exposure-bracked image sets for macro work. It would be trivial to add a rotating platform and Arduino control to the system so I could automatically take 360-degree image sets for use in photogrammetry/etc.

you'er video and information helped me out a bunch, you did not waist your time, i learned a lot in a short time, big thanks!

i would love to see more this kind content!

Glad to see this market overview and to see you've exceeded the 8 views you expected. Seems to me this might make for an interesting side gig. Start up costs under 10K and interesting work as well

I think 3D scanning on any phone and CAD experience is amazing this is truly good nie just to learn how to use it all

I use the Occipital Structure sensor, which mounts to my iPad. It was $700-ish for the sensor. (I already had an iPad.) It's perfectly within the Goldilocks zone you were alluding to.

I'm totally with you on waiting it out on 3D scanning. You helped me a lot. One question I have though. I was considering the iPhone to do some scanning of interior rooms of my house. But you mentioned the Intel scanner. Would it work as well as the iPhone for my use? If so, isn't the Intel scanner cheaper than the iPhone?

Cool video! I had played with scanning about 10 years ago on Subaru rally cars. Boy all those head aches sound painfully familiar. We had a combo of faro arm data and attempts at scans. I never did get the models to a useable state. Ill have to try again with with some of these scanners you mentioned

Thanks for the video - I've been having the same quandary. Mid way through an EV conversion I wish now I'd bought a professional grade scanner. I went with the old-school ruler + micrometer - but got plenty of stuff wrong. From my research, one of the best value at the moment is Peel 3D CAD - which will export (some) features direct to CAD & has Solidworks integration (maybe others) built in. I'll consider it again for my next daft project (whatever it turns out to be). PS. You don't have to use the super-expensive targets. I've used the little circles of paper from a hole punch stuck on with spit!

There is a relation between balance improvement and the facilitation of sensory feedback related to the activation of the plantar cutaneous mechanoreceptors. From a clinical point of view, the application of additional tactile cues may have therapeutic benefits in relation to fall prevention or to improve specific types of chronic pain. Postural Insoles are a great way to help optimize joint alignment. They use wedge and frequency technology to target specialized sensory receptors in the skin of your feet, allowing your brain to create new neural pathways to "activate" otherwise "lazy" muscles.

Absolutely with you on the +/- 1000 buck scanner option . I often wonder why the price of good quality scanners hasn't dropped in recent years. Loved the vid Cheers

I got to use an Artec scanner at work and I was really happy with the thing. So much better then the consumer stuff. It's kinda sad that there really isn't a "mid range" option. You either have to buy the pro scanners or deal with the consumer stuff

This was very helpful. Thank you.

Pop scanner scan can be corrected by pausing scan and hitting back a few times and then hit play again. It will pick back up just before where it fell off.

What a kickass way to perhaps tease the new engine for the Honda

Part of the audience that's there. Definitely a market for mid-priced scanner. Well done.

Looking at anything except for Einscan - I had very similar results with first gen Xbox Kinect camera and app examples included in SDK to actually capture data. It's basically free. You can't get any precise measurements, but can get basic shape shape with good details.

For what it's worth, I found this video 10x more fascinating than a t-shirt cannon. Have you put any thought/research into Kinect-based solutions? I know those have been around for a decade now and are likely very far from state-of-the-art but this seems like a problem that is 10% hardware 90% software/algorithm, and I'm curious how the Kinect's community solutions compare to commercial ones.

Love this channel

- Some 3D modeling programs have functions that can reduce the details of meshes selectively and using different algorithms to produce different kinds of results depending on what you're looking for. - It looks the stitched-together surfaces can sometimes create more problems than it's worth. Even if it's not pretty, a raw point-map would much more useful for details rather than the inferred surfaces created by the processors for the cheap scanners. - I'm not sure if it's supported, but using guide blocks would go a long way towards maintaining position. Basically it's just a cube with different images on each surface that the processor can use to assert camera position, and if you affix it to the target object, it'll give you a very reliable relative position between camera and target. Just stick it onto unimportant features. - Again, I'm not sure if it's supported but for non-LIDAR scanners you could also use colored lights shining from different angles to increase the contrast on harder-to-read surfaces, or use patterned lights like from those cheapish laser pointers with shaped apertures that create shapes you can project onto surfaces. - There's a bunch of good research on stitching together multiple photos to create some really good quality 3D models, which would be hella easier to manage. All you'd need is to take some pictures with a half decent camera and send the photo gallery through the processor, and if needed, just take more pictures and process it again. No need for careful real-time scanning and wasting all your time from minor mistakes or hardware/software deficiencies. That being said, I'm not sure just how good the quality is or how long until research turns into accessible products. Some of these types of research do release their source code or even the bare-bones programs they used, though, so if you look around you might luck out.

If you're scanning an old Jag you might as well add the serial number to the file description. I've worked on a few old Jags and they are as one off as any purpose built race car I've worked on. I helped on repairing a damaged passenger door hinge and latch on an XK120 that was in an accident. We had access to two cars the same year and found there are very few interchangeable parts, even the doors would not fit each other. The hinges looked liked they were flame cut and all three were made to different shapes. Inside the door skin is a wood frame and even that was made differently across the three cars. I'm not saying the cars weren't well made they were just repeatability wasn't highly sought after.

Thanks for the input.

The software is what makes the difference in hand scanning, or using photogrammetry. Neither can ever replace the inherent precision of terrestrial lasers, however they can get close enough for many applications.

Years ago in university Formula SAE times, I spent a month of one summer painfully trying to model the mounting points and oil pan flange of our CBR600 engine. At first I started with a 3-axis CMM we had in a lab, which was a nightmare and was soon given up on. I ended up using a flatbed scanner for the flange and scaling with caliper measurements. Might have been a lot easier with 3D scanners.

Honestly, this sort of content is what I love! I use photogrammetry due to that price difference that you mention, and while the scaling is a big issue, it still worked fantastic for my purposes! I built an entire transmission tunnel and floor for a Nissan Pao to RWD swap in a 13B FC. It took quite awhile, and 3 scans that needed manually aligned. Though, all that effort worked out well once I cut out all 36 panels on a plasma CNC table and it all fit within a 1/10 of an inch in most spaces!

You got a subscriber. Thanks for the video and info!

Dude you have the best sense of humour! I crack up during every video! Also I learn a ton too! Thanks!

I have used large expensive commercial scanners like the FARO and even they are not as good as you would hope, models generated through them still require a ton of tweaking to be useful. The lack of progress in this field is one of the reasons we still don't have reliable 100% automated vehicles, they need the lidar scanners and software that can determine what things are to be bullet proof and basically boilerplate level refined.

great video.. answered all my noob questions. ty!

love your videos, highlight of my week

You could also use an htc vive controller with some 3d sculpting software to plot a bunch of key points, then make a cad model using the points as a guide. I haven't tried it,it's just an idea i jag while watching this, but I think it might work.

Dang I was hoping the news would be better on this. If you can get away with modeling 1 face at a time what I do is take a picture with a ruler laying on the part you need a model of. Then in solidworks (and other CAD software too, Im sure) you can insert a picture into a sketch. After using the ruler to set the scale you can just trace the picture into the sketch. As long as the part isnt too big (or camera too close) to get perspective errors this works incredibly well. But isnt 3D 😔. Very quick and simple for 2D sketches though!

I've used Heges before, just to add and FYI, it also has ipad-via-wifi-to-remote-capabilities built in. Thanks for making this video, very comprehensive, been here before and back then I was looking for a video like this but couldn't find it. Now I know I don't/do need to spend many bucks to buy a hardware scanner based on the project :)

Dude your channel is the bomb-diggity, tanks for sharin. . .

on the pop you dont have to start over, you just press the back button or the undo until your back where you left off before the messup.

If they were a bit cheaper, there might be a business model around hiring out the high quality scanners. A bit like people can hire expensive tools they only nee once a year, or expensive camera lenses or things like that.

Obviously this item is the perfect candidate for a tool library, I have borrowed thermal cameras to detect thermal gaps in my house from my local library in Melbourne, Australia.

So only 8 people are interested in 3D scanners but 2,900 people liked this video because of your amazing personality.

Great Scanner review, I’m going to look into the remote monitor for the phone you use and the other “frotogrammetry” (I’m using that from now on) software. I noticed the lovely BMW motorcycle engine you were scanning, is that perhaps from my past recommendation to use for the car for the shaft drive?

I would also love that middle ground price point. If there was one I'm sure it would do well as there would be no competition in that price point.

Great report. Love the humour. Cheers!

I'm looking into updating our 3D scanner at work. We are looking to improve upon our 20 um scanner. A human red blood cell is about 8 um in diameter. Working in the turbine industry. The 40 um accuracy of the best EinScan would still be 2x decrease. There are better options out there (creaform, GOM, etc).

me: "what is a video about 3d scanning doing in my subscriptions?" -about to scroll past when i see the uploader- "oh it's from superfastmatt? in that case i'll watch it; i'm sure it'll be interesting" and it certainly was. i love your videos, you make everything interesting even if i don't particularly care about the subject or when you go into something that's way beyond my knowledge base lol

I can recommend the handyscan black series if you got deep pockets, its 100 micron point distance is unbeatable

As a engineer that likes to wrench on cars myself, this is my favorite car channel on UKposts!

Love your work 👍

Epic stuff man, these the questions we need answered :P Thanks a bunch =) and to that, ill subscribe

I wish you had used the pop2 version. as an engineer myself , I am fighting with this problem. ugh. keep up the great videos.

seems like the biggest and most simple improvements could done by changing scanning method. Anyone using the product has access to decent smooth floor space. some sort of jig with caster wheels that roles around the object. Motorizing and even programming the jig to move itself would be fairly straight forward.

Scanners and 3D printers will go along so nicely :)
