摘要
基于移动扫描系统提出一套新的1∶2 000地形图检验流程,通过与全站仪、RTK等传统数学精度检验方式,论证移动扫描系统三维点云数学精度对于1∶2 000地形图精度检测的适用性。通过与传统人工外业巡视等传统地理精度检验方式,对比、分析全景影像对于地理精度检测的辅助作用。实验结果表明,移动扫描系统的三维点云数据数学精度符合1∶2 000地形图测绘成果质量精度检测要求,以全景影像辅助地理精度检查一定程度降低外业检验时长。因此,将移动扫描系统运用于1∶2 000等大比例尺地形图成果质量检验工作能一定程度优化检验流程、提升质检效率,为测绘成果质量检验工作提供新思路。
Based on mobile scanning system, we presented a new inspection and acceptance process for 1∶2 000 topographic map. Then, we compared and analyzed the traditional inspection methods such as total station, to prove the applicability of Leica mobile scanning system in inspection and acceptance of 1∶2 000 topographic map. The experimental results show that the mathematical accuracy of the mobile scanning system meets the requirements of the quality inspection of 1∶2 000 topographic map, and improves the work efficiency. This study can provide new ideas for inspection and acceptance of 1∶2 000 topographic map.
