Abstract
A system and method for using a machine vision system to locate and register patterns in an object using range data is provided. The machine vision system includes an acquisition system for acquiring a range image of an object. The system also includes a machine vision search tool coupled to the acquisition system for locating an instance of a trained pattern in the image. The tool registering the trained pattern transformed by at least two translational degrees of freedom and at least one non-translational degree of freedom with respect to an image plane. The acquisition system preferably includes a three-dimensional camera.
