三维激光彩色扫描测距系统设计与三维点云模型重建3D 三维激光彩色扫描测距系统设计与三维点云模型重建 3D Laser Colored Laser Scanning and Range Detecting System Design and 3D Point Cloud Data ModeI Reconstruction Abstract With the rapid development of 3D scanning and ranging technology．3D point cloud is more and more widely applied in the field of industrial detection，autonomous navigation， reverse engineering，etc．In the process of digitalizing the real world，3D point cloud data can record geometric properties and location message of the object’S surface accurately while the 2D image records the color and texture．The close integration of the two will produce a new kind of digital media，namely 3D colored point cloud data．3D colored point cloud data is the upgrade of 3D point cloud data as it possesses not only the geometry and location information ofthe object’S surface but the color and texture ofthat，with which it Can illustrate the real world more precisely． In order to obtain 3D colored point cloud data，this thesis has designed new 3D colored laser scanning and range detecting system，mainly composed of 2D laser scanning rangefinder， high—speed industrial camera，electric turntable and host computer。2D laser scanning rangefinder and high—speed industrial camera installed onto the electric turntable．When launched．it will rotate at a constant speed for the two to carry out the omnidirectionaI collection of 3D point cloud data and 2D image data．The host computer gets 3D point cloud data and 2D image data through Ethemet communication，and conduct precise integration to obtain omnidirectional 3 D colored point cloud data．In this thesis．VC++and OpenGL are employed to write a software to collect and integrate 3D colored point cloud data，attempting to integrate and display 3D colored point cloud data． 3D point cloud data processing technology has played a key role as the basis of a variety of applications．Model reconstruction is very important technology in 3D point cloud data processing．Considering the non-uniform of 3D po
