Geometric Processing of Low Altitude Remote Sensing Images Captured by Unmanned Airship

  • 摘要: 介绍了基于无人驾驶飞艇的低空遥感系统的组成及技术指标,详细论述了飞艇按航线自动控制飞行、遥感影像自动获取,以及低空遥感影像匹配、相对定向、区域网平差、全景图和正射影像生成等处理与分析。试验结果说明,低空遥感系统可以满足大重叠度、高分辨率立体影像获取的需求,在大比例尺测图、精细三维重建等领域具有广阔的应用前景。

     

    Abstract: The composition and technical characteristics of low altitude remote sensing system based on unmanned airship are introduced. The unmanned airship automated flies along the predefined routes and captures image sequences under the controlment of autopilot system. Geometric processing of captured low altitude stereo images, such as image matching, relative orientation, bundle block adjustment, panorama and orthoimage generation, are addressed in detail. Experimental results show that the developed system is qualified for high overlap and high resolution stereo imagery acquisition, and has good potential in large scale mapping and precise three dimensional reconstruction areas.
