  • Patent number: 3997795
    Abstract: In an arrangement for control of aerial cameras an objective for imaging a surveyed area onto a projection plane is employed. The image frequency and the drift are determined from the speed and the direction of the image motion on the projection plane, whereas the grey values are exploited for the exposure setting of the camera. The obtained parameters are used for controlling the camera. The projection plane is covered at least partially by one or more than one digital photo detector matrix. The signals produced are fed into an information processing stage connected to the photodetector matrix for being processed in accordance with a preselected program. An output unit controls the camera in dependence of the processed signals. The projection plane can be arranged in the image plane of the camera objective and can be employed to evaluate the entire photogram.
