车载移动测量系统应用于城市大比例尺地形图更新

Application of Mobile Measurement System in Urban Large Scale Relief Map Update

将车载移动测量系统与城市大比例尺数字地形图测图相结合,成功地将车载移动测量系统运用于城市大比例尺测图更新应用中。通过在测区内布设靶标控制点,对比靶标的点云量算坐标与全站仪实测实际坐标,统计分析车载移动测量系统的测图精度。实验结果表明,车载移动测量系统能够满足城市大比例尺地形图测图要求。

With the combination of the mobile measurement system and the city large scale digital topographic map mapping,the mobile measurement system can be used in the application of urban large scale map updating. By measuring the target area layout control point. Comparison of target point cloud coordinate calculation and actual total station coordinate. Statistical analysis of the accuracy of the measurement system of vehicle mobile measurement system. The experimental results show that the measurement system can meet the requirements of large scale topographic map of the city.
