摘　　要：利用ADS40线阵数字相机获取的影像,选取典型岛屿区域,分别采用了基站差分无控制点参与平差计算、基站差分有控制点参与平差计算、精密单点定位无控制点参与平差计算和精密单点定位有控制点参与平差计算四种方案进行试验和精度分析,得出了试验结论。In order to research on the triangulation accuracy on the island and reef areas, some typical islands are selected. The images are captured by ADS40 which is the representative digital pushbroom camera. Two different schemes are used in GPS/IMU data processing. One is using differential GPS method and the other is using GPS precise point positioning method. In each scheme, the triangulation accuracy of combined adjustment with and without control points are compared and analyzed and the experiment results are concluded.
