360°激光扫描仪测角误差检校方法探讨

Calibration methods of angle measurement error of 360° laser scanner

本文在分析激光扫描仪测角误差影响因素基础上,探讨360°车载激光扫描仪测角误差的2种检校方法,即动态法和静态法;并结合TerraScan软件和matlab处理点云数据,设计数学模型对误差进行改正;最后对试验结果进行了详细分析。

This paper first analyzed the influence factors of angle measurement error of laser scanner, and mainly studied and discussed two calibration methods of angle measurement error of 360 ° vehicle-based laser scanner, one is dynamic method and the other is static one; then, the paper processed the point cloud data with TerraScan software and matlab and conducted a detailed analysis of the testing results; finally, it concluded that the laser scanner calibration techniques and methods would become more mature and perfect in the future.
