摘要
为解决远离大陆的海岛礁地形测绘的技术难题,在西沙群岛应用IMU/DGPS辅助海岛礁无控航空摄影技术进行了作业,经实测成果检验,影像精度满足大比例尺航测要求。基于试验分析,对在南海岛礁进行航空摄影常见问题提出了解决建议,有助于航空摄影测量技术在海岛礁测绘中的应用推广。
To solve the problems for topographic surveys of islands far from the mainland,aerial photographic survey without control points based on the IMU/DGPS technology was carried out in the Xisha Islands.Validated by actual surveys,the imagery fulfiled the accuracy requirements of large scale aerial photographic surveys.Profiting from the experiment,suggestions were provided for frequently occured questions in islands aerial photography in the South China Sea to promote the application of aerial photographic survey technology in island surveying and mapping.
