摘要
为获取三维数据信息及对所获得的三维数据信息进行处理,首先介绍了陕西科技大学计算机实验室三维激光扫描系统的组成及工作原理,对三维激光扫描系统的关键性技术如摄像机标定、影响测量精度因素、散乱数据点的消除以及点云数据的压缩问题的研究进行了概述,并指出该技术的应用在某些方面还需进一步完善和改进。
To obtain and process the three-dimensional data information. Firstly, the composition and working principle of the three-dimensional laser scanning system of the Shaanxi University of Science and Technology computer laboratory is introduced. The key technologies of the three-dimensional laser scanning system, such as camera calibration, the factors affecting the measurement accuracy, the elimination of scattered data points, and the compression problem of point cloud data are overviewed. And the applications of the technology which require further improvement in some areas are pointed out.
