摘　　要：基于无人机原始航片数据量大、网络传输速度慢的问题,本文开发了原始航片压缩工具,实现了保留原始分辨率及纹理特征的压缩算法,并成功应用于“四川长宁6.0级地震”“8·20汶川强降雨特大山洪泥石流灾害”等应急测绘任务中,为数据传输、后方处理提供了技术支撑。Based on the problem of large data volume and slow network transmission of UAV original aerial photos,this paper develops a compression tool for original aerial photos to realize compression algorithm that retains original resolution and texture features,and successfully applies it to emergency mapping tasks such as"Changning 6.0 magnitude earthquake in Sichuan province","8.20 Wenchuan heavy rainfall,torrential flood and debris flow disaster",which provides technology for data transmission and post-processing operative support.
