Positioning mark points are often adopted when operating the existing hand-held laser scanners,which may shelter some of the data.To solve this problem,a new method based on the homography matrix and the Hof line extraction method is proposed for data splicing,which can avoid sticking the mark points in the scanning process.The experimental results show that the 3D-point cloud data can be obtained accurately by using this method,and the splicing error is below 1 mm.
