> Depth estimation: It works well enough in practice. https://www.stereolabs.com/zed-2/ https://www.stereolabs.com/zed-2/ I have no experience with the zed 2, but the zed 1 did not convince me and it had similar fancy marketing visualization as featured by the page you linked. Don't trust anyone who shows you - depth estimations from the viewpoint of the camera - color coded depth estimation In neither case can you judge the accuracy Vision-based depth estimation is hard for the general case, where you need to cover a non-tiny depth range to cover, work indoors and outdoors and cannot rely on great texture. All vision-based methods I know of break under circumstances that are not too uncommon for robots. Laser works much better, but the information density is not that great. Radar works well in some applications, badly in others. So I'd consider it "solved" when you throw a very costly combination of sensors on the problem.
