On-machine Camera Calibration Based on Image Sequence
This paper proposes an on-machine calibration method of industry camera based on image sequence. A set of monocular stereo system was established on the NC milling machine. A calibration target with 7×7 circular array marks was designed to meet the requirements of finding enough and accurate correspondence relationship. Calibration method is illustrated involving taking image sequence, detecting the position of the calibration board and the marking points, finding the marking points correspondence with their projection, determining the camera parameters through minimization algorithm. The accuracy of camera parameter with the number of calibration image is discussed. Consequently, choosing 10 calibration images is appropriate for onmachine calibration.
