3D Structure from Motion Using Homocentric Spherical Spatiotemporal Image Analysis

A technique for building a three-dimensional description of a static scene from a spatiotemporal image is presented. This technique utilizes Homocentric Spherical Spatiotemporal Image (HSSI) analysis and makes allowances for camera rotation, which is a wider class of camera motion than that in ordinary spatiotemporal image analysis. Experiments with real images from a translating and rotating camera were preformed, and the three dimensional structures in a static scene were reconstructed. With this technique, it is possible to distinguish objects with a rotating camera at long distances and to measure them with much greater accuracy.
