| 摘 要： | 弹道相机通常是在夜间对飞行目标进行拍摄,在相机类型不改变的情况下要达到白天工作能力具有一定困难,主要障碍是拍摄后,底板上目标与背景的衬比(度)下降,难以达到判读要求.针对这一问题,本文详细叙述了各因素对判读要求的影响,提出了改善相机白天工作能力的可行方法.

| Abstract: | Generally,the photographs of flight targets are taken by the ballistic camera at night. Usingthe same type of ballistic camera to take photographs in the daytime,there are some difficulties. Themain obstacle is that the contrast of target and background in the negative descended,and the targetinformation can not be read. lP this paper,the factors of the influence on read requests are described,and the practicable ways to improve the work ability of the ballistic camera in the daytime are putforward. |
