| 摘 要： | 本文依据光学原理分析了环境压力对相机内方位元素的影响，并采用光学设计计算和检定测试两种方法进行了实验，得出了相机所处环境压力不同，其检定主距将产生较大改变的结论。作者还通过研究目前卫星摄影测量相机低压检定方法，揭示出相机低压检定结果含有测试条件下的大气折射作用。文末作者就卫星摄影测量如何使用相机低压检定值提出了看法。

| Abstract: | :
The paper gives a discussion of the effect of atmospheric pressure and experiments with two methods of optical designed calcuation and calibration and reaches the conclu sion that the calibrated focal lenth is greatly changed with the change of atmospheric pressure. It is obtained that there will be some changes in the refraction at the photo graphic glass windows and refraction greatly affects the calibrated focal lenth. Finally, the paper puts forword the suggestion on the use of the calibrating data under the low pressure. |
