Extracting 3D information from stereo photography is a standard problem (perhaps the central focus) of the area of study known as photogrammetry. The techniques are discussed in various textbooks on the subject and make heavy use of nonlinear least squares adjustments. In this talk we discuss the general least squares problem, how it is solved iteratively by linearization, and give examples of its use in photogrammetry.
