Abstract

A wide field CCD camera has been developed and mounted on a small size pilotless airplane for photogrammetric test. Since the focal length, relative aperture and swath of the camera are closely related to the size of the CCD pixel, and the resolution and signal to noise ratio of the camera are determined by the CCD characteristics. Great care has been paid on the selection of CCD at the beginning of the system design, and great effort has been made to decrease the output noise of the camera, which depends on CCD and circuit noise. As the pilotless airplane is small in size and light in weight, the effect of wind stream and direction to the plane attitude should be taken into account. This paper presents the design of the pilotless airborne wide field CCD camera. Two main parameters, namely the resolution and signal to noise ratio of the camera are discussed, and the effect of attitude variation of the plane to the image taken is analyzed, and measures taken to overcome the effect and flight test results are presented.
