Abstract： Three-dimensional laser scanning and tilt photography have their own advantages and disadvantages： high accuracy of three-dimensional laser scanning， but the measurement range is small， UAV photogrammetry range is wide， but easy to missing data. In view of the above problems， two kinds of measurement techniques are used to acquire spatial data to improve the accuracy of the three-dimensional model of the survey area， and then applied research is carried out. The research shows that the integrated application of the two technologies can realize the complete collection of 3D data in the survey area； the unified control point coordinate system and the iterative nearest neighbor point registration algorithm can effectively fuse the two types of point clouds， and can build a high-efficiency， high-precision， high-resolution 3D model； the method improves the automation of the measurement operation and image clearance. It can be applied to many kinds of occasions.
