Problems solved by technology
The current solution is generally to manually adjust or use the control unit to add scanning function to the photoelectric stabilized platform, but the scanning is only relative to the platform's own coordinate system, and it cannot judge whether the image captured by the platform's current attitude exceeds the observation area. The scan feature for is not available
[0004] The main purpose of the UAV-borne photoelectric stabilization platform is to accurately observe the ground observation area, and to quickly find and identify suspicious moving targets. However, it is difficult for the human eye to respond quickly to moving targets in the image when the video shakes, and Visual fatigue caused by jitter greatly reduces the efficiency of scouting

Embodiment Construction
[0027] The working principle and working process of the present invention will be further explained below in conjunction with the drawings.
[0028] Such as figure 1 As shown, an automatic reconnaissance system for an unmanned aerial vehicle photoelectric stabilized platform based on image matching includes an external communication unit 1, an image signal processing unit 2, a platform control unit 3, a platform stabilization frame 4, and a photoelectric payload 5.
[0029] The external communication unit 1 is mainly used for two-way data communication between the system and the user side, and the communication content includes instructions and image information; the external communication unit 1 forwards the received automatic scanning instructions sent from the outside to the image signal processing unit 2.
[0030] Image signal processing unit 2, mainly for image signal acquisition and algorithm processing of photoelectric load, including image matching operation and scanning path ...

The invention discloses an image-matching-based automatic reconnaissance system of an unmanned aerial vehicle mounted photoelectric stabilization platform. According to the system, route planning and automatic scanning control for automatic scanning are implemented according to the image registration relationship of photoelectric load in large and small view fields, so that automatic traverse scanning on images of a preset observation area is completed; in automatic scanning, images of adjacent image sequences can be matched, motion compensation can be implemented according to the matching relationship, and frame difference calculation can be also implemented, so that a moving target can be detected, real-time automatic recognition on the moving target in an image can be achieved, and the reconnaissance accuracy and efficiency are improved.
Description
Technical field [0001] The invention relates to an automatic reconnaissance system for an unmanned aerial vehicle-borne photoelectric stabilization platform based on image matching, and belongs to the technical field of unmanned aerial vehicle reconnaissance. Background technique [0002] While the UAV-borne photoelectric stabilization platform provides mechanical stabilization functions for the photoelectric payload, it must achieve long-term accurate observation of the ground observation area under a small field of view. In order to quickly find suspicious moving targets, observers also need to identify moving targets in the image. [0003] In order to achieve high-resolution viewing of the preset viewing area, currently the optical axis of the platform is manually locked to the viewing area under a large field of view, and then the camera equipment is adjusted to a small field of view, and the angle of the optical axis is manually changed by adding a moment. Take a look. The e...
