Abstract
A method of and a system for scanning a scene for the purpose of classifying a plurality of moving objects located in the scene and having an average distance between them, including the steps of performing a sweep of the scene, during the sweep, producing a multiplicity of detections of at least one portion of the scene at a rate such that a distance traveled by the moving objects between detections is small with respect to the average distance, and calculating, from the multiple detections, two-dimensional motion information for at least some of the moving objects.
Claims15
A method of scanning a scene for the purpose of classifying a plurality of moving objects located in the scene and having an average distance between them, the method comprising the steps of:
- performing a sweep of said scene in steps defining portions of said scene;
- during each step, producing a multiplicity of images of at least one portion of said scene at a rate such that a distance traveled by said moving objects between images is small with respect to said average distance;
- and
- calculating, from the difference between said multiple images, two-dimensional motion information for at least some of said moving objects.
A system for scanning a scene for the purpose of classifying a plurality of moving objects located in the scene and having an average distance between them, the system comprising:
- a sensor system for scanning a portion of said scene;
- a motor for sweeping said sensor system through said scene in steps defining portions of said scene;
- a sensor controller for producing a multiplicity of images of at least one portion of said scene at a rate such that a distance traveled by said moving objects between images is small with respect to said average distance;
- and
- a processor for producing, from the difference between said multiple images, two-dimensional motion information for at least some of said moving objects.
