Stereo vision isn't exactly "solved," but there are a ton of very good solutions out there both open source and commercial. The "Semi-Global Block Matching" algorithm implementation in the OpenCV library[1] is very good even though the algorithm is over 10 years old at this point. I've played around with the new Intel RealSense[2] units recently as well, which are stereo cameras with onboard processing and a nice IR pattern projector. Pretty cheap, and for the most part they "just work." [1] https://docs.opencv.org/4.4.0/d2/d85/classcv_1_1StereoSGBM.html https://docs.opencv.org/4.4.0/d2/d85/classcv_1_1StereoSGBM.h...
