摘　　要：随着无人机技术的快速发展,以测量为目的的无人机摄影测量技术已广泛应用到各行各业。相比于常用测量技术,无人机摄影测量技术需要处理抖动平台下的序列摄影图像,技术难度更大。利用红黑树数据结构实现无人机摄影图像的大尺度特征点匹配连接,基于相机标定和捆绑调整两个无人机摄影测量的关键技术环节,实现无人机海岸线遥感影像的快速拼接。With the rapid development of UAV technology, photogrammetric technology involving high resolution camera is widespreadly applied to lots of fields. Compared with traditional survey methods, it is more difficult to handle with aerial images, captured by cameras on unstable aerial platform. In this paper, red-black data structure is used in large scale tie point matching and connecting. Meanwhile the camera calibration and bundle adjustment technologies are used to generate coastline mosaic using UVA images.
