WIDE-FIELD HIGH-RESOLUTION CAMERA DEVICE FOR AIRCRAFT

摘要

A wide-field high-resolution airborne camera device for use both as a line-scan camera and as a target-tracking video camera, wherein the wide field is achieved by juxtaposing shots taken at different angles. For this purpose, a video camera (2) is attached to an angular motion assembly so that the camera axis rotates through a series of steps (4-10) about an axis (3) parallel to the direction in which the aircraft (21) is travelling, then swings back to its starting position. The device is further provided with a picture selection unit for taking a picture at each step, whereafter the pictures are transmitted to the ground or recorded on board the aircraft. The device is instantly convertible into a tracking device by directly servo-controlling the camera axis direction.
