Aiming at the problem of low accuracy, low efficiency in the parallelism measurement of porous workpiece, this paper proposes a parallelism measurement method based on computer vision technology. The images of both ends of the workpiece are acquired, after camera calibration, image distortion correction, two sides coordinate unification, filtering, edge extraction, circle calculation and a series of image preprocessing, parallelism can be calculated. The experiment shows that this method has high precision, high efficiency and it is simple to operate, it provides a new way for geometric measurement.
