摘要:

针对应急测绘中对无人机视频数据快速获取及处理的需求,提出了一种无人机视频影像快速配准方法。首先采用时间索引和线性/球面插值方法实现视频帧与无人机定位定姿信息的时间同步,根据数字微分纠正算法实现视频帧的地理编码,实现视频帧间的粗略配准,然后控制仿射变换模型中的缩放因子不变对纠正后视频帧的坐标进行调整,完成视频帧间的精配准。试验结果表明该方法能够得到航带内视频帧较好的配准效果。

Abstract:

A fast registration method for unmanned aerial vehicle (UAV) video frames was proposed in the paper, according to the need of rapid acquisition and processing of UAV video data in maritime surveys. Firstly,the time synchronization between the video frames and UAV positions and attitude information was realized using the method of time index and linear/spherical interpolation. Then the rough registration of video frames was obtained after geocoding video frames with digital differential rectification algorithm. Finally, the precise registration was obtained by controlling the zoom factor in affine transformation model to adjust geographic coordinates of the processed frames. The results show that this method is qualified for obtaining precise registration of video frames within route.
