Abstract
This paper researches the technonlogy of point cloud data reconstruction in laser scanning, and proposes a fast method of curved surface reconstruction based on point cloud. It analyses the relative position of the relationship of data points between adjacent scanning lines, and improves scanning lines subdivision algorithm based on triangular subdivision, according to the characteristics of the progressive scanning laser scanning. The point cloud data is irregular triangular mesh divided. It uses geometrical relationship to make triangular network construction. At the same time, on the basis of the triangle model, the triangular mesh is optimized locally, to make texture mapping, and to be rebuild in the end. Experimental results show that this algorithm can effectively improve the speed and quality of triangular network construction, eliminate voids and improve the reconstruction results.
