In this paper, a novel light pen type of 3D\|coordinate measurement technique is extracted. A 3D\|coordinate measurement system with three sets of CCD devices being used to realize intersection converge imaging is introduced, which is called as the light pen type of measurement system because the measuring head is a pen with light sources. The structure design, measurement principles and measurement accuracy analysis are expounded. The theoretical analysis and experiments prove that this system with the advanced features of simple structure, high automation, high accuracy and wide\|ranging application can be used in the measurement fields of mechanical manufacture, robot, auto, aviation and medicine effectively.
