Flexible coordinate measuring system based on multi lateration laser tracking interferometery principle is a effective method to detect 3 D coordinate of large tool's characteristic points,and possible to get high accuracy.The paper describe a method using four beam laser tracking interferometer,so we can use the system's hardware redundant ability to accomplish system self calibration and losing information recover.This method is different from triangulation method and spherica approach in depending on the angle detection,it just need length detecting information to determine 3 D coordinate.
