无人机低空遥感影像数据的获取与处理

Capture and processing of low altitude remote sensing images by UAV

介绍无人机低空遥感系统的构成和技术指标,论述影像数据的获取、影像匀色与裁边、重叠度计算、拼接全景影像图、生成正射影像等处理分析方法,并针对地震灾区重建数据获取进行实验。实验结果表明无人机低空遥感系统完全能满足实际需要,能解决多云雾地区遥感影像资料获取困难的问题,在大比例尺测图、三维景观重建、土地利用调查、环境监测等领域具有良好的应用前景。

The composition and technical indicators of low altitude remote sensing system based on unmanned aerial vehicle are introduced.The image data acquisition,image uniform color and triming,overlap calculation,panoramic mosaic image and orthophoto generation are addressed and for the reconstruction of earthquake-stricken areas to acquire the experimental data.Experimental results show that low-altitude UAV remote sensing system is fully able to meet the actual needs,and it can resolve the problems of multi-cloud region remote sensing image data acquisition,and has good potential in large scale mapping,three dimensional scene reconstruction,land-use survey and environmental monitoring areas.
