In order to obtain a higher dynamic photographic resolution, the image motion must be compensated. The key in compensation is to acquire the current image motion speed accurately. 为获得较高的动态照象分辨力,必须对象移进行补偿,而补偿的关键是准确地获得当前的象移速度。
During aerial camera photograph, photographic distance occur change with flight platform, argue to satisfy resolution, the location of camera lens will be adjusted correspondingly. 为满足摄影分辨力的要求,在航空相机拍摄过程中,镜头位置要随着摄影距离的改变相应调整。
As a powerful tool to detect ultrafast phenomenon, high-speed photographic devices with high time resolution are being widely concerned. 作为探索超快过程的有利工具,高时间分辨率的高速拍摄器材正受到越来越多的关注。
