Hi,

It is quite recent, but we can indeed use rtabmap without a camera, only a lidar for mapping. In this mode however, visual loop closure detection is disabled but proximity detection can work (to find small loop closures). If we want to add a camera only for coloring point clouds or texturing a resulting mesh from lidar, there are some works to do on exporting dialog (this has never been tried yet).

Yes, 3D lidars like Quanergy/Ouster/Velodyne can be used in rtabmap. In this paper, we evaluated RTAB-Map with a velodyne for autonomous car (KITTI dataset).


Hand-held 3D lidar scanning is still in development. I just recently had my hands on a velodyne PUCK, so some examples may appear in the next months.

cheers,
Mathieu
