【摘要】：通過數(shù)字測(cè)繪航空攝影快速獲取高分辨率影像,能快速生成DEM、正射影像、三維景觀圖等測(cè)繪產(chǎn)品,能夠迅速了解災(zāi)情并獲取受災(zāi)地區(qū)詳細(xì)的地面三維信息,為救援隊(duì)伍提供精確、可靠的測(cè)量數(shù)據(jù)。通過在受災(zāi)區(qū)域獲取的航空影像,基于PHOTOMOD軟件進(jìn)行數(shù)據(jù)快速后處理實(shí)驗(yàn)。經(jīng)過效率分析和精度統(tǒng)計(jì),證明其效率和取得的正射影像成果可以達(dá)到指導(dǎo)應(yīng)急救災(zāi)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.
