摘要:

将背负式移动激光扫描系统应用在测绘大比例尺地形图中,其扫描精度至关重要。本文利用徕卡Pegasus Backpack对苏州工业园园区测绘地理信息大楼进行扫描,采用Inertial Explorer、Infinity、AoTumatic Processing对点云数据进行预处理,运用RealWorks提取特征点,将特征点在MicroStation V8联图中绘制成1:500地形图。通过与传统方法绘制的1:500地形图相叠合,发现两幅地形图具有很好重合度。对地物检测点精度分析后,得到点位中误差为0.026 m,高程中误差为0.041 m。研究结果表明徕卡Pegasus Backpack满足1:500地形图测量精度要求。

关键词: 点云数据, 1:500地形图, 精度分析

Abstract:

The application of the piggyback mobile laser scanning system in the mapping of large scale topographic maps is critical to the scanning accuracy. Using the Leica Pegasus Backpack to scan the survey and mapping geographic information building of Suzhou Industrial Park, use Inertial Explorer, Infinity, AoTumatic Processing to preprocess the point cloud data, use RealWorks to extract feature points, and draw the feature points in the MicroStation V8 joint diagram as 1:500 topographic maps. After superimposing the 1:500 topographic map drawn by the traditional method, it is found that the two topographic maps have a good coincidence. After the accuracy analysis of the ground object detection point, the error in the point is 0.026 m, and the error in the elevation is 0.041 m. The results show that Leica Pegasus Backpack meets the accuracy requirements of 1:500 topographic map measurement.

Key words: point cloud data, 1:500 topographic map, precision analysis
