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。通过对相机斜距离焦的分析
提出了一种新的离焦补偿方法
研制出一种双层导轨、双层凸轮的自动调焦补偿机构
使相机在照相过程中保持像面稳定
并对斜距调焦原理进行了实际检验。
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. The effect of these three factors on a camera is discussed and a simple mathematical equation is proposed for calculation of how much a camera is out of focus. A new simple method is to compensate out of focus of oblique photographic distance. The principle is very easy to implement. Finally
the paper introduces a auto-focusing system with double-deck guideway and double-deck cam
and its focusing of oblique photography is tested.
