| 摘 要： | 移动测量系统获取点云的精度,不仅取决于各子系统的精度,同时取决于子系统之间的关系参数的质量,也就是激光扫描仪、GPS、INS惯导单元之间的关系参数。文中从获取点云坐标的原理入手,分析推导系统误差整体模型,进行精度分析。最后利用模型分析实测数据,并将计算得到的理论精度结果与检校的实测精度进行比较。

| Abstract: | The accuracy of derived MMS（Mobile Mapping System） cloudy points depends on not only the system components but also the quality of the bore-sighting parameters among the system components： namely,the laser,GPS,and INS units.In this paper,the error budget of MMS are analyzed and we are interested in analyzing the effect of random noise and systematic bases in the measurements from the components on the final product.The findings of the conducted analysis will be verified through experimental results from calibration filed. |
