Based on the advantages of high accuracy and high speed of three-dimensional measurement by hand-held optical knife method,aiming at obtaining complete point cloud data from multiple measurements,a 3-label point cloud registration algorithm is proposed.The mathematical principle of the 3-label point transformation algorithm is analyzed.The common feature points of adjacent measurements are accurately obtained by checkerboard label,and the calculation method of transformation matrix is deduced.A stitching accuracy method is proposed.Finally,based on the standard sphere and the standard plane,the application accuracy of the algorithm is tested.
