Pose determination and tracking by matching 3D objects to a 2D sensor

摘要

An improved method of pose determination and tracking does away with conventional segmentation while taking advantage of multi-degree-of-freedom numerical fitting or match filtering as opposed to a syntactic segment or feature oriented combinatorial match. The technique may be used to improve image database query based on object shape descriptors by allowing the user to request images from a database or video sequence which contain a key object described by a geometric description that the user designates or supplies. The approach is also applicable to target or object acquisition and tracking based on the matching of one or a set of object shape data structures.
