The invention relates to a regulation mechanism of a reconnoitering area of an aerial camera, belonging to the technical field of the mechanical structure of the aerial camera. The regulation mechanism changes the reconnoitering area by regulating an attitude angle of the aerial camera and comprises an inner frame, a middle frame, an outer frame, a pitching attitude angle driving and feedback device, a tooth-shaped belt, a rolling attitude angle driving and feedback device, a first pitching support shaft, a second pitching support shaft, a large belt wheel, a first rolling support shaft, a second rolling support shaft and a large gear. When in installment, an X shaft is consistent with the flight direction of an airborne platform, and the regulation mechanism defines the revolving shaft motion of the aerial camera around the X shaft direction as roll angle change, defines the revolving shaft motion of the aerial camera around a Y shaft as pitching angle change and can timely regulate the reconnoitering area according to reconnoitering task needs. The invention enhances the practicality of push-broom TDI and CCD aerial cameras and the reconnoitering capability, has larger regulation range, 90 degrees of the regulation range of a roll angle and a pitching attitude angle, stable and reliable structure, flexible and convenient use and low cost.
Description
Technical field: [0001] The invention belongs to the mechanical structure technical field of aerial photography, and relates to an adjustment mechanism for a push-broom TDI CCD aerial camera reconnaissance area. Background technique: [0002] The currently equipped push-broom TDI CCD aerial cameras are installed on the airborne platform in a fixed position, so the area that it can detect depends on the flight path of the airborne platform and the field of view of the camera. If you want to detect targets in areas far away from the route, you can only change the route of the airborne platform. It is very difficult to change the route of the airborne platform in time, and it takes a long time and space. Therefore, a kind of adjustment mechanism that changes the camera detection area in time is needed. Invention content: [0003] In order to solve the reconnaissance area problem existing in the background technology, the practicability of the aerial camera is improved. The ...
