This research focuses on vision based gear profile measurement system in precision engineering. It mainly discusses the camera system integrated to the measurement apparatus. The system can record the video as well as is able to save the image frames in JPEG format during measurement. Vision based measurement is very useful to increase the performance of the measurement. It can help to analyze the measurement result later on whenever it's necessary to investigate. The system records video and saves image frames in real-time and also it's possible to open the video file in offline mode. In this paper, a vision based inspection system has been proposed mainly for the surface error measurement of various types of gears.
