无人机遥感影像镶嵌技术综述

无人机影像镶嵌是低空遥感数据处理系统中的一个重要内容，其目的是将序列无人机影像拼接成一幅具有地理坐标的影像。为了使该领域的研究人员对当前无人机影像镶嵌方法有较全面的了解，对各种无人机影像镶嵌方法进行了综述。多项式法、卡尔曼滤波法、基于SfM点云匹配和传统空中三角测量法均需要地面控制点，而对偶四元数POS辅助空中三角测量方法无需或者只需少量地面控制点，将在无人机影像镶嵌领域有较为广阔的应用前景。

Summary of UAV remote sensing image mosaicking technology

The UAV image mosaic is an important content in the low-altitude remote sensing data processing system, which aims to splice a sequence of UAV images into an image with geographic coordinates. In order to make researchers in this field have a more comprehensive understanding of UAV image mosaic methods, several methods of mosaicking UAV images are reviewed. Polynomial method, Kalman filtering method, the method based on SfM points cloud matching and the traditional aerial triangulation method all?require ground control points, while POS-assisted aerial triangulation method based on dual quaternion does not need or only needs a small amount of ground control points. As a result, the POS-assisted aerial triangulation method based on dual quaternion will have a more broad application prospects in the field of UAV image mosaic.
