摘要(Abstract)：

针对无人机遥感航测系统在应急服务等时效性要求比较高的应用需求,该文结合当前计算机硬件发展,提出结合CUDA技术和Voronoi图索引的纹理多尺度高效调度算法实现无人机航空遥感影像的实时快速正摄可视化方法,该方法有别于传统的摄影测量成图作业处理流程,无须进行影像的正射纠正和拼接处理,直接利用原始影像实现整个测区影像的高分辨率漫游,在紧急情况下甚至可以直接利用GNSS和IMU数据,快速实现测区影像的漫游;结合航空摄影数据处理流程和阶段,提出了4种不同的实时可视化方案,实现效率和精度优化。最后利用无人机飞行的实验数据对该方法进行了验证。结果表明,该方法对加强无人机遥感航测系统在应急服务中的时效性非常有意义。
