Abstract

In this paper, we propose a new automatic laser sheet calibration in laser triangulation. The existing methods are relatively monotonous, inefficient, and subject to a large number of human interventions. Our new method has three advantages. First of all, the new method is an automated method while the traditional one is manual; Secondly, the new method simplifies the calibration process and costs fewer time; Finally, the new method can obtain higher accuracy result. We calibrated the parameters of camera and laser plane by the new method, and calculated the height of corresponding points on laser line by laser triangulation. The validity of our new method is verified by analyzing and comparing the error of height value
