以双介质摄影测量原理为基础，利用海岛无人机影像开展了航空双介质摄影测量试验与分析。首先简单介绍了双介质摄影测量原理，论述了双介质摄影测量对海水折射率的精度要求，提出了一种解算高程改正系数方法，在此基础上开展了基于某岛低空无人机影像的双介质水下礁盘深度量测试验。试验表明，航空双介质摄影测量在实际应用中是可行的，对航空摄影条件要求比较高。

Based on the principle of two-media photogrammetry and with islands UAV images,a test of two-media photogrammetry is carried out.Fi rstly,there is an introduction of the principle of two-media photogram-metry.In the fol lowing step,the two-media photogrammetry requi rements on the accuracy of the refractive index of sea water is discussed.Then,a new method for calculating the elevation correction coefficient is developed.The test procedure of two-media underwater reefs depth measurement based on low-altitude UAV images of underwater reefs surrounding the islands is designed.The test shows that aerial two-media photogram-metry is feasible in practical appl ication,but relatively high requi rements for aerial photography conditions.
