【Abstract】 A new rapid measuring method of multi light knife for 3 D free form surface is put forward. The measuring principle is expatiated, and the ways to realize the multi light knife are discussed. The main factors affecting the accuracy of the measuring system are analyzed, and a virtual net calibration method is applied to calibrate each of the multi light knife. When a complex surface is measured, a new light knife coding method is applied to solve this kind of problem. By the measurement experiment it is proved that the means of multi light knife is a utilitarian technology to obtain the 3D information of large objects.更多还原
