无人机航空摄影质量评价

无人机航空遥感系统获取遥感影像具有多种特性。通过多次试验，得到大量的图像和信息数据。本文利用无人机飞行实验所获得的控制数据，分别从像片重叠度、航带弯曲、像片旋转角及航高差等方面对无人机航空摄影质量进行评定，并绘制了无人机实飞航迹与预设航迹，显示了无人机的定点拍摄效果。然后分别利用地面控制点和无人机飞行控制数据对所获得的遥感影像进行了正射校正处理，均能获得正射影像。结果说明作为一种新型的对地观测系统，它的空中摄影质量满足摄影测量的基本要求。

Aerial Photogrammetric Quality Evaluation of the UAV

The UAVRSS(Unmanned Aviation Vehicle Remote Sensing System) has many advantages in capturing remote sensing images.With the flight control data of the UAV,an evaluation on the photographic quality of the UAV is given,including overlap rate,the flight path camber,forward overlap,side overlap,flight height and swing angle.Moreover,the flight path was drawn to show the result of the pointing shot.Then the images are othorectified through GCPs and the UAV flight control.The results show that the photographic quality of the UAV is satisfied with the criterion of photogrammetry.
