The measurement of bending angle is important for high precision bending machine. In order to detect the real time bending angle of the bending workpiece, a non-contact angle measurement system was developed, which combined binocular cameras and linear laser. In this study, the system was designed based on the laser triangulation. By analyzing the images(More)
