Abstract

This paper proposes a flexible 3D coordinate system based on a theodolite pair. The math model of the system is based on the least square method. A transition coordinates system is established to meet the requirement to move the theodolite pair in many on-site situations. This paper gives an example that the flexible 3D coordinate system is employed to complete the global calibration of a vision-based inspection system for the body-in white of car.
