摘　　要：论文介绍了OpenGL依次读取多个物体点云数据的坐标值数据范围不一致时通用性视景区设置的方法。运用OpenGL成像机理来设置通用性视景区,从而实现庞大点云数据的读取和模型的重构。经仿真验证,该方法能够很好地实现多个物体坐标值数据范围不一致的点云数据的读取,最后加以实时旋转、平移和缩放证明视景区设置的可靠性。This paper introduces the way OpenGL set the universal vision zone to read multiple objects＇ cloud data of different coordinate figures＇ data area. The cloud data acquisition adopts optical grating projection measurement system to get the plaster and amination mouse head portrait＇s dense cloud data. Then use OpenGL imaging mechanism to set the universal vision zone to accomplish the acquisition of cloud data and model restruction. This method is confirmed to realize the reading of multiple objects＇ cloud data of dif- ferent coordinate figures＇ data are. At last, the reliability was proved by Real-time rotation, translation and zoom.
