| 摘 要： | 介绍了车载激光测绘系统的组成和工作原理。对系统中的激光扫描仪增设了可见光源作为标校参考光,以便有效地确定激光测量中心和扫描方向,并直接测量部分标校参数。根据其特点,设计了基于可见参考光的标校方案。进行了静态标校试验和激光测绘系统动态精度测量试验,试验得到标定误差为0.028 1 m,系统平面定位误差为0.288 m。通过系统精度试验分析,进一步验证了标定方案的正确性和有效性。

| Abstract: | Abstract ： The composition and principle of a vehicle-borne laser mapping system are described in this paper. A visible light source is designed for a laser scanner in the vehicle-borne laser mapping system, by which the laser measuring center and scanning direction can be determined effectively and a parts of calibration parame- ters are able to be measured directly. A calibration scheme based on the visible light source is designed, then static calibration experiment and dynamic measurement are performed. Obtained results show that the calibra- ting error is 0. 028 1 m and plane positioning error is 0. 288 m. The experiment results and analysis prove the correctness and validity of calibration project. |
