Line matching in stereo vision
Charles E. Coldwell, Jack Fitzer · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
The problem of reconstructing real-world positions of three-dimensional objects from stereo views has proved very difficult, because the problem is inherently underdetermined. By reducing the problem to a one-line problem, and using precision image acquisition hardware, range information may be obtained with relatively simple correlation calculations.
