基于三维激光扫描仪测距精度的分析

Analysis of Distance Measurement Based on 3D Laser Scanner

三维激光扫描仪是传统测量的技术革新,研究三维激光扫描仪基本性能,便于更好在实际项目中应用。通过试验,扫描仪测距精度在40 m范围内,点位中误差低于12 mm;在20 m范围内,点位中误差低于6 mm,满足三维激光扫描仪的标称精度。扫描仪距离与中误差之间存在二次函数关系,随着扫描距离增加中误差增大,测距精度降低。

3 D laser scanner was the traditional measurement of technological innovation, the basic performance of 3D laser scanner was studied easy to apply better in practical projects. The accuracy of the scanner ranging showed that the error was less than 12mm in the range of 40m by the test, and the error in the point was less than 6mm in the range of 20m meeting the nominal accuracy of 3D laser scanners. There was a quadratic function relationship between the scanner distance and the medium error. With the increase of the scanning distance increasing the error, the ranging accuracy was reduced.
