A lidar sensor will almost certainly _always_ be lower latency than any sort of image processing engine.
A lidar gives you a stream of 3d points in the order of megavertices a second.
The processing pipeline for any visual system is at least frame rate of the camera (the faster the camera, the less light it can get) plus the GPU transfer time(if you are using AI) then processing.
this means you are looking at ~200ms latency before you know where things are.
Lidar is a brilliant sensor. Maybe it will be supplanted by some sexy beamforming Thz radar, but not in the near future.
- kevin_thibedeau 8y agoCameras built using dedicated hardware similar to what lidar systems are using would not have that sort of latency. You don't have to receive a full frame of data before it can be processed if you're not using generic COTS cameras.
- KaiserPro 8y agosure, you can have the thing spitting out lines as fast like, thats not the issue. you are limited by shutter speed, as you know, even if the shutter isn't global. (lidar is too, but we'll get to that in a bit) Any kind of object/slam/3d recovery system will almost certianly use descriptors. Something like orb/surf/sift/other require a whole bunch of pixels before they can actually work. only once you have feature detection can you extract 3d information. (either in stereo or monocular) A datum from a lidar has intrinsic value, as its a 3d point. Much more importantly it does drift, event the best slam drifts horribly. Lidar will be superior for at least 5 years, with major investment possibly 10.
