Research of Model on the Horizontal Angle Accuracy of 3D-Laser Scanner

摘要: 随着三维激光扫描技术的广泛应用，三维激光扫描仪的精度检测、评估也更加重要。本文提出了一种以高精度全站仪为基准对三维激光扫描仪水平角测角精度进行检测和改正方法，建立平差模型，并编写计算程序。在检校场中，以Leica TCA2003高精度全站仪的标靶角度测量结果作为基准，对Leica ScanStation C10三维激光扫描仪经过扫描、反算得到标靶角度进行检校。通过程序计算对三维激光扫描仪的水平角测量精度进行评定和改正。

Abstract: Nowadays, the applications of 3D-Laser Scanning Technology are widespread, so the examination and assessment of 3D-Laser Scanner’s accuracy become more and more important. This paper in-troduces a method of 3D-Laser Scanner’s horizontal angle accuracy examination and assessment, by using high-accuracy total station as reference, then setting up calibration mode and compiling computer program. In the examination field, using the target angle surveying result of high-accu- racy total station Leica TCA 2003 as reference, the target angle scanning result of 3D-Laser Scanner Leica ScanStation C10 can be examined. Then, the assessment and correction of the 3D-Laser Scanner’s horizontal angle accuracy can calculate by the computer program.
