ABSTRACT:
A method of representing spatial relations among objects in the environment uses a Delaunay triangulation as the data structure to store the spatial relations when the objects are represented in the form of simplified objects such as cuboids. The method receives image data corresponding to the environment and recognizes the objects in the image data, and updates the Delaunay triangulation so that the Delaunay triangulation is consistent with the recognized objects. Furthermore, a proximity query can be carried out using the Delaunay triangulation.
