| 摘 要： | 基于无人机航空影像摄影技术,提出单独控制点影像处理、优化POS(定位定姿系统,Position and Orientation System)影像处理和优化POS结合控制点处理三类共计6种影像处理方案,对比分析了6种影像处理方案的效果,结果表明:采用单独控制点影像处理的效果最佳,其次为优化POS结合控制点影像处理,最差的为原始POS数据影像处理;单独控制点和多基准CORS(连续运行参考站,Gontinuously Operating Reference Stations)基站优化POS数据+3控制点处理方案的精度满足1∶500比例尺精度要求,具有较高的影响处理精度,但是单独控制点需要在野外布设大量的像控点,不利于航测工作效率,在设备和环境条件允许下,推荐采用CORS基站优化POS数据+控制点方式进行影像处理。

| Abstract: | Based on the aerial image photography technology of UAV,3 kinds of image processing schemes were put forward,including processing with GCPs,processing with original POS,processing combining optimized POS with GCPs.It was showed that processing with GCPs is the best,followed by the processing combining optimized POS with GCPs.Processing with GCPs and processing combining multi reference CORS optimized POS with 3 GCPs meet the 1∶500 scale accuracy.However,a large number of GCPs were needed by fieldwork,which is not conducive to the aerial survey efficiency.Therefore,it is recommended to use the scheme of multi reference CORS optimized POS and 3 GCPs for image processing. |
