RESEARCH ON VISUALIZATION OF GROUND LASER RADAR DATA BASED ON OSG
Three-dimensional(3D)laser scanning is a new advanced technology integrating light,machine,electricity,and computer technologies.It can conduct 3D scanning to the whole shape and form of space objects with high precision.With this technology,you can directly collect the point cloud data of a ground object and create the structure of it for rendering.People use excellent 3D rendering engine to optimize and display the 3D model in order to meet the higher requirements of real time realism rendering and the complexity of the scene.OpenSceneGraph(OSG)is an open source 3D graphics engine.Compared with the current mainstream 3D rendering engine,OSG is practical,economical,and easy to expand.Therefore,OSG is widely used in the fields of virtual simulation,virtual reality,science and engineering visualization.In this paper,a dynamic and interactive ground LiDAR data visualization platform is constructed based on the OSG and the cross-platform C++ application development framework Qt.In view of the point cloud data of.txt format and the triangulation network data file of.obj format,the functions of 3D laser point cloud and triangulation network data display are realized.It is proved by experiments that the platform is of strong practical value as it is easy to operate and provides good interaction.
