Webcam Based System for Press Part Industrial Inspection

Industrial inspection is one of the crucial factors to ensure quality of product before reach the market. The inspection tasks can be done by using visual system such as human vision or machine vision or combination of both. In this paper, we describe a system that capable to control quality of press part product. The scheme is based on CMOS web-camera (webcam) in a production line. The main objectives are to develop image processing algorithm which can measure the dimension of parts and decide whether it is accepted or rejected. In this research, we divide the system into hardware and software components. The result shows its possibility to be used as automated visual inspection system for press part quality control. The dimensions of the part can be obtained by calculating the pixel value.
