In order to improve the measurement accuracy of the laser displacement sensor,the laser triangulation displacement measuring system is established.The spot subdivision location algorithms of the system are studied,such as the Gaussian curve fitting,traditional gray weighted centroid and gray square weighted centroid.First,according to the principle of laser triangulation,the displacement measuring system is built.Then,objects are moved by the high-precision motorized stage,obtaining multiple sets of linear CCD image data.Next,these data respectively are processed by the above several algorithms to obtain the corresponding coordinates of the laser spot,the system is calibrated respectively.
