无人机1∶500测图的应用与分析

The UAV Application and Analysis of 1∶500 Mapping

以桐柏县安鹏镇作为试验区,进行1∶500地形图航空摄影测量。本文介绍了无人机低空摄影测量在1∶500航测成图中的应用,包括本次实验使用无人机平台及传感器参数,像片控制点布设及空三加密等技术要求,并对此次试验精度进行分析。该方法有效地解决了无人机航测在大比例尺成图中的关键问题,大大节省了工作时间和财力,有效地提高了工作效率,结果表明了该技术的可应用于大比例尺地形图测绘中,为无人机应用于大比例尺测图提供了好的借鉴经验。

Taking Pengzhen,Tongbai County as an test area to carry out,1∶500 topographic map of aerial photogrammetry.This paper introduces Unmanned Aerial Vehicle（UAV）low altitude Photogrammetry in1∶500 aerial application diagram,the experimental use of the UAV platform and the parameters of the sensor,photo control points and empty three encryption and other technical requirements of and analyses the accuracy of the test.This method solves the key issues of the UAV aerial survey in the map the scale,greatly saves time and resources and effectively improves the working efficiency.The results show that this technology can he applied in large scale topographic mapping,and provide a good reference for the using of UAV image measurement in large scale.
