2/15/2011 1 Stereo and Correspondence Stereo Vision How to recover depth from images? Problem formulation: Given two images formed in the planes P1 and P2 , we want to solve: For a point m in P1 , determine which point m ' in P2 plane that it corresponds to. The term correspond means that they are the images of the same physical point M . This is what is commonly known as the correspondence problem . Given two corresponding points m and m ', compute the 3-D coordinates of M relative to some global reference frame. This is known as the reconstruction problem .
