Abstract :
A vision system for the automatic assembly of electronic components is developed. The vision system presents information about positions, orientations, and quality of rectangular-shaped electronic components in real time. The orientation is detected by the windowed Hough transform along with a simple edge-detection method, whereas the position of each component is determined by using the projection method with dynamic thresholding. In addition, real-time implementation of the vision system in which multiple central processors are used for parallel processing of the algorithms is described
