A Measuring System of Focus Surface Message to Aerial Cameras Using CCD Camera

Abstract:

A measuring system of the focus surface message of bigger aperture aerial camera was described. The image is received by the collimator of long focus and area CCD camera. The location and size of the optimum image were measured effectively by using dynamic scanning and least square method. Therefore, the accurate measurements of the focus of aerial camera lens and the location of the actual imaging surface can be realized in the relative accuracies of 0.1% and 100% respectively.
