What are the advantages of LIDAR-based slam and vision-based slam?

LIDAR:

1. high resolution, high ranging accuracy

2. strong resistance to active interference

3. good detection performance

4. not affected by light

5. large speed range

Vision (mainly camera):

Cheap, the camera to do algorithm development of the personnel are also more, the technology is relatively mature. Disadvantages of the camera, first, it is very difficult to obtain accurate three-dimensional information (monocular camera is almost impossible, and some people have proposed binocular or trinocular camera to do it); another disadvantage is that it is more limited by ambient light.
