本文介绍了一个标定摄像机响应曲线的算法，通过自动曝光的视点固定拍摄的视频序列标定摄像机响应曲线。
In this paper, we introduce another algorithm to do it, which USES an automatically exposed video sequence gathered at a fixed observing point.
为了获得高清晰的地面目标图像，航空摄影机需要自动控制曝光。
For capturing high-resolution images of the ground target, automatic exposure control system is required for aerial cameras.
但是目前国内广泛使用的X射线机的点片曝光装置还存在自动化程度低、控制精度差、曝光精度低以及体积大等缺点。
However, the film exposure device of the currently widespread-used X-ray machine has poor quality of image, a low level of automation, poor precision controlled and film exposure and large size.
