Engineering Application of Three-dimensional Laser Scanner
Abstract:Now the three dimensional laser scan technology is a developing high-new technology on international, with the widespread applications of the three dimensional laser scanners in engineering, and has already aroused the general scientific researcher's interests. This paper first introduces the working principle of 3D laser scanner, and then points out the procedure and methods to process the points cloud. Finally, the method producing the 3D models of buildings is expatiated and the procedure and the result of this approach are introduced with a factual example. The result shows that the proposes of rapid three-dimensional visual modeling build from laser scanning point cloud data of the Complex and irregular buildings is well in both time and effort, the advantage of the three dimensional laser scan technology is better than the existing three-dimensional modeling software’s.
