A convenient global calibration method for multi-camera system based on two planar targets is proposed,with the two targets  rigidly connected and rotating around the same axis.The pose relation between the two targets can be unknown.This method is not only suitable for the system based on stereo vision,but also for the system based on monocular vision.It has been used in the factory-calibration of four-wheel aligner with 2 or 4 cameras,and the calibration precision meets the requirement.

Key words: multi-camera measurement system, global calibration, vision measurement, monocular vision
