Based on the experience gained from the development of a long focus, oblique, real_time, aerial camera, it is pointed out that the camera maybe out of focus is due to changes in temperature, atmospheric pressure and oblique photographic distance.

基于一种长焦距斜视实时航空相机的研制,探讨了导致相机离焦的原因,指出环境(大气压力、温度)变化和照相斜距的变化是导致相机离焦的主要原因,分别从温度、大气压力、照相斜距这三个方面的变化对相机离焦的影响进行讨论,给出了计算相机离焦量的简易数学方程。
