We present an efficient technique that uses bidirectional template matching for gross defect detection in 3D objects. The template matching utilizes computer-aided design models and is carried out on 3D data formed by merging range data collected from multiple known viewpoints. The inspection scheme assumes that the identity of the object is known but that the object's position is unknown, although constrained. A matching technique based on the Hausdorff distance is used to determine the pose of the object. The inspection scheme is tested on real range images of several iron castings.
