碩士 === 國立中央大學 === 機械工程研究所 === 92 === The complexity of product manufacturing increases because of the faster development of CAD/CAM and the higher techniques of manufacturing on the present day. The technique of inspection have to improve to keep up with the development of manufacturing. It is general to use image inspection as a method of inspection. This work combine the CAD system and the image inspection system to simplify the steps of image inspection by using CAD system. The steps of image inspection could be automated by CAD aiding to decrease repeated operation steps and to save manpower and time. This work have to obtain the coordinate transformation by registration to ensure the data between two system could correspond correctly because the coordinate between CAD system and image system is different. Then we can choose the tolerance items and inspected elements and proceed image inspection by setting inspection plan. In the same time, we can obtain the outline point group from the image using image process techniques. Finally, we get the inspection results by analyzing the tolerance of image point groups based on corresponding CAD elements.
