【摘要】：通过数字测绘航空摄影快速获取高分辨率影像,能快速生成DEM、正射影像、三维景观图等测绘产品,能够迅速了解灾情并获取受灾地区详细的地面三维信息,为救援队伍提供精确、可靠的测量数据。通过在受灾区域获取的航空影像,基于PHOTOMOD软件进行数据快速后处理实验。经过效率分析和精度统计,证明其效率和取得的正射影像成果可以达到指导应急救灾的需求。
[Abstract]:Through digital surveying and mapping aerial photography to quickly obtain high-resolution images, can quickly generate DEM, orthophotography, three-dimensional landscape map and other surveying and mapping products, can quickly understand the disaster situation and obtain detailed three-dimensional information of the ground in the affected areas. Provide accurate and reliable measurement data for rescue team. Through the aerial image obtained in the disaster area, the data post-processing experiment based on PHOTOMOD software is carried out. Through efficiency analysis and precision statistics, it is proved that its efficiency and orthophotographic results can meet the needs of guiding emergency relief.
