基于POS的无人机航片快速纠正在应急测绘保障中的应用

Application of Rapid Correction of UAV Aerial Film Based on POS in Emergency Surveying and Mapping Support

文章以原始航片数据和无人机POS数据为基础,恢复了飞行照片的地理位置,通过使用Arcgis Engine软件对照片进行了快速纠正,再将自动处理的照片快速加载到影像地图上,并在森林火灾应急测绘保障任务中得到了成功的应用。为政府和相关部门提供了清晰的影像信息,对相关部门研判火情、灾后过火面积分析及评估灾害损失等提供了地理信息支持。

Based on the original aerial film data and UAV POS data,this paper restores the geographical location of flight photos.With the using of Arcgis Engine software,the photos are quickly corrected,and the automatically processed photos are quickly loaded onto the image map.This has been successfully applied in emergency surveying and support tasks of forest fire.It provides clear image information for the government and relevant departments,and provides geographical information support for relevant departments to study and judge the fire situation,the burned area after the disaster,and to analyze and evaluate the disaster loss.
