Abstract: This paper discusses the problem of tracking a geometric object using data from a real-time laser rangefinder. Because of the volume of data we choose to preprocess each range image to find the edge points. Then 3D lines and circles are extracted from these edge points. By matching these extracted curves to the model of each object we are able to compute the object pose, that is its position and orientation. Some examples are given of the operation of these algorithms using simulated range data.!7
