Latest Patents
Changhua Wu holds a patent titled "System and method for determining poses of objects." This invention involves a sophisticated process where a 3D model of an object is rendered for various poses by arranging virtual point light sources around the lens of a virtual camera. The shadows created during this process are utilized to obtain oriented depth edges of the object illuminated from multiple directions. These oriented depth edges are then stored in a database for further analysis. A camera captures images of the scene, casting shadows onto the scene from different directions. The system can handle multiple objects arranged in arbitrary poses with respect to each other. The poses of the objects are determined by comparing the oriented depth edges obtained from the acquired images to those stored in the database. This comparison evaluates a cost function based on chamfer matching, which can be accelerated using downhill simplex optimization.
