Abstract
A key technology of multi-camera visual measurement system is global calibration. The global calibration methods existed either has disadvantages such as high cost and complicated operation, or has limited application areas only for visual system based on stereo vision. A convenient global calibration method for multi-camera system based on two planar targets is proposed in this paper, and the pose relation between the two targets can be unknown. This method is not only suitable for system based on stereo vision, but also for system based on monocular vision. It has been used in the factory-calibration of four-wheel aligner consisted of 2 or 4 cameras, and calibration precision meet the requirement.
