Object pose (location and orientation) estimation is a
common task in many computer vision applications. Although
many methods exist, most algorithms need manual
initialization and lack robustness to illumination variation,
appearance change, and partial occlusions. We propose
a fast method for automatic pose estimation without manual
initialization based on shape matching of a 3D model
to a range image of the scene. We developed a new error
function to compare the input range image to pre-computed
range maps of the 3D model. We use the tremendous dataparallel
processing performance of modern graphics hardware
to evaluate and minimize the error function on many
range images in parallel. Our algorithm is simple and accurately
estimates the pose of partially occluded objects in
cluttered scenes in about one second.
