Abstract
An image processing system provides the capability of extracting three dimensional motion information from two dimensional images. The image processing system achieves such extraction by analyzing selected image points. The selected image points correspond to the projection of points on a three dimensional object. The object is moving over time (i.e. translating and rotating with respect to the imaging device). The selected image points are processed in parallel by a plurality of processors to first determine the translational velocity. Next, the rotational velocity of the patch is determined. Lastly, the relative depth of each image point is determined in light of the previously determined translational and rotational velocity. The image processing system accomplishes this task by using an imager and a processing means. The system has potential applications in filming and in robotics.
