Real-time 3D SLAM with a VLP-16 LiDAR. Point cloud resolution is 5 centimeters. Grid cells on the ground are 10 x 10 meters. No other sensors used. Loop closures are computed by ICP scan matching with scans from nearby poses, using GTSAM as a back-end.

Hi, great video. Can i ask, dis you use Rtab map with only a lidar and thats it? If so this is exactly what id like to do but there are no how to... like how to get rtab to use the lidar? I could do tjis using a kinect but it takes too long and becomes inacuate as it can create a wall map on top of an already viwed wall your trying to pass by or fill a gap in. Any feed back on this would be great as id love to just grab my laptop, a lidar and start mapping. Thanks

Hello. Very awesome job. Thanks for showing this video, and I have some questions. In ICP algorithm there are many methods for selecting corresponding points, which methods did you choose? How many miliseconds dose it cost for one scan matching?

Can you please tell me what was the cost of this lidar? I am searching online and as if the authority is advertising in such a way that they don't want to disclose the cost.

Awesome. Your software could works on RPLidar A1 sensor too? Thanks!

Sure, but that sensor is a 2d lidar so you might as well use a 2d slam library

you need to stick this on the underside of a hexacopter for large area mapping
