The structure from motion problem in computer vision is the problem of determining camera position and orientation as well as the 3D positions of scene features using the motion of image features only. The analogous problem for audio and radio is the problem of determining sender and receiver positions using the received audio or radio signal only. For both video, audio and radio there are a number of challenges, e.g. feature detection, robust feature matching and robust parameter estimation. The problem is challenging also because of the non-linear nature of the problem. In the talk a summary of results of both theoretical and applied nature is presented.
