| Summary: | The motion of image edge detectors is used to infer 3D scene information by simultaneously solving the aperture and structure-from-motion problems. It is shown how additional constraints or information are required and two formal solutions are given. In one the motion of edge features at eight or more image points is used to solve for the motion and surface parameters (the 8-point algorithm). In the other it is assumed that the motion is known as a priori (the 3-point algorithm). This algorithm is used to illustrate the numerical stability of these solutions. |
