Multi-camera measurement system has advantages in measuring curved surface structures and improving the measurement accuracy, which is widely applied in many fields. The application field, portable degree and measurement cost are determined by the distribution form of cameras in the system. The distribution forms of cameras in multi-camera systems under different calibration methods are researched. The relationship between the number of cameras and the measurement field of view (FoV) in three different distribution forms is derived. Both advantages and disadvantages of different forms are analyzed and compared. The results show that the cost of the multi-camera measurement system based on close-range photography calibration method is lower. Moreover, the overlapped area of FoV between stereo vision sub-system is no longer necessary, which makes the installation and arrangement of the multi-camera system more flexible.
