Abstract :
In this paper we present a two-step stereo calibration method of binocular intersection VMD measurement system based on OpenCV. First, calibrate the two cameras separately, and get the camera´s intrinsic parameters. Second, solve the extrinsic parameters from the stereo image pairs and the camera´s intrinsic parameters. The experiment shows that this two-step calibration method for binocular intersection VMD measurement system can achieve better results than calibrate the system directly in one step.
