선형 레이저빔을 이용한 자동차부품의 치수측정에 관한 연구

A new dimension measuring method for the measurement of diameter has been developed using laser triangulation. The 3-D data of an object was calculated from the 2 dimensional image information obtained by the laser stripe using the laser triangulation. The system can measure the diameter of hole not only in a normal plane but also in an incline plane. In this paper, the theoretical formula and calibration were described. The measuring precision of the system was verified by experiment.
