| 摘 要： | 本文首先介绍航空摄影测量数字相机相对于传统的胶片相机所具有的优点，然后重点分析了市场上最新流行的两种大面阵航空摄影测量数字相机的等效中心投影像片的形成方法及其测量精度。实验分析表明：航空摄影测量数字相机系统用于平坦地区作业时能获得较高的精度，但用于山区作业时，作业精度明显下降，因此在地形起伏较大的地区，若作业精度要求较高，则应谨慎使用这两种数字相机。

| Abstract: | The paper firstly introduces the advantages of the two kinds of digital cameras applied in aerial photogrammery comparing to that of the film camera. Then,it analyzes about the method how the equivalence central projection is created and the measure accuracy of two kinds of aerial photogrammetry digital camera th~,t can be achieved on market. The experiments and analysis show that the digital camera can get high accuracy in planer area,but if it is used in a mountainous area,the accuracy declines evidently. If the task is in a mountainous area and requires high accuracy, it should be cautious by using these two kinds of digital cameras. |
