无人机DOM的制作及其在城市更新中的应用

Production of UAV DOM and its Application in Urban Renewal

采用固定翼无人机平台,对城市更新区域进行正射影像图航摄,通过与大比例尺数字线划图对比进行精度评估,表明无人机遥感技术可以满足1∶2 000比例尺测图的精度要求,最后说明了该技术在城市更新项目中的应用。

The aerial photography of the urban renewal area was carried out by using the fixed wing Unmanned Aerial Vehicle（ UAV） platform,and the precision was evaluated by comparison with the large scale Digital Line Graphic.The results showed that the UAV remote sensing technology could meet the accuracy requirement of 1 ∶ 2000 scale map,finally describes the application of the technology in the urban renewal project.
