三维激光扫描仪精度测试及应用

Accuracy testing and application of 3D laser scanner

介绍了三维激光扫描仪的基本原理及其应用于桩基测量精度分析的测试方法。按照工程需求,布置控制点,选择陆地高架桥下的圆柱作为观测目标,分别用三维激光扫描仪和全站仪测量出圆心坐标,以全站仪测量成果为基准,分析三维激光扫描仪的测量精度,探索其在工程测量中的应用。

The basic principle of 3D laser scanner, and the test methods of its positional accuracy in pile surveying were introduced in this paper. According to engineering requirements, we arranged control points, chose columns under the viaduct in land as observation target, measured the center coordinates respectively using 3D laser scanner and total station, analyzed the measuring accuracy of 3D laser scanner based on total station measuring results, and explored its application in engineering surveying.
