3D Laser Scaning Technology In The 3D Reconstruction Of The Landscape Of Applied Research

3D laser scanning technology as the current rapid development of new mapping technology, and its data collection is not only fast and accurate. It appears not only reduced the intensity measurement project and broaden the application areas, but also i mprove efficiency.In recent years,3D laser scanning technology has become more mature and the cost of 3D laser scanner declining, the use of 3D laser scanner for point cloud data and point cloud data processing and analysis,3D landscape has become an important means of reconstruction.Point cloud data is 3D laser scanning technology can be widel y used in the key, which is 3D reconstruction of the landscape plays a vital role. For example, the cultural works of art, pattern recognition, reverse engineering and other fields are using 3D laser scanning technology to obtain the point cloud data, and its wide range of applications, more and more people begin to focus research on the subj ect. In this paper,3D laser scanning technology to some of the unique 3D reconstruct ion of buildings. The following is the reconstruction of buildings made of study:This paper introduces the 3D laser scanning system works,compared with the traditional measurement differences and advantages. Leica scanstation2 scanner as an example to further elaborate 3D laser scanner and application of the composition. And 3D reconstruction techniques from the processes, methods and an overview of today's applications.Of 3D laser scanning technology in the 3D reconstruction of the building issue s related to the application.Different point of view through the scanner scanned the o riginal buildings of the point cloud data, and these multi-perspective mosaic of point c loud data, filtering, has been building for 3D modeling of the surface of the required point cloud data Then these processing point cloud data based on the various compon ents of the building separate modeling. We can get the ideal 3D model of buildings.This paper analyzes the 3D landscape reconstruction error. Because of these er rors from the measurement process, affecting the accuracy of the measurement point cl oud data, thereby affecting the accuracy of 3D reconstruction of the building.In this paper, to obtain the point cloud the actual position error and the size of buildings the size of two aspects of the model were compared with the study of th e accuracy of position error is quite good, compared with the model building was hig her than that of real estate Measuring the accuracy of specifications. This article also point cloud data acquisition, processing and analysis put forward some further research content.
