RTK-SLAM激光影像背包测绘机器人精度验证

Precision verification of RTK-SLAM backpacked mobile mapping robot

随着测绘新技术不断的发展壮大,测绘作业的方式也有了日新月异的变化。背负式移动扫描系统的出现,大大降低了外业作业的劳动强度,而且其测绘的精度也得到了明显的改善。文中主要以背负式移动扫描系统为研究对象,通过以近领域提取点云的方式,对扫描点云做精确的坐标比对实验。通过实验,该扫描系统的平面精度与高程精度均满足大比例尺地形图测绘的要求,并且在测绘效率上比传统技术得到了显著地提高。

In recent years,with the development of new mapping technology,the way of surveying and mapping operations had also changed with each passing day.With the appearance of backpacked mobile scanning system,the labor intensity of field operations were reduced greatly,and the efficiency of mapping were improved greatly.In this paper,taking the backpacked mobile scanning system as the research object mainly,by extracting the point cloud in the near field,the accurate coordinate comparison experiments were carried out on the scanned point cloud.Through experiments,the plane accuracy and the elevation accuracy of the system met the requirements of the large-scale topographic mapping,and mapping efficiency had been significantly improved compared with traditional technology.
