Abstract

In an optical three dimensional measurement system, structural light is often used in order to improve the measurement speed and reduce the cost of the system. But the experiments have demonstrated that the precision in such a system is reduced with the increasing of the depth of the detected object. So in the system a series of planes were introduced as reference planes, in which the first plane is called the base plane. The planes divide the area of the object into several parts. The information processing of every part bases on a corresponding plane. The system improves the measurement precision, as well as increasing the complexity of information processing. The new arithmetic of unwrapping is used and relativity of all the points in different area has been found in the research.
