Problems solved by technology
Among them, methods (1) and (2) are difficult to apply to moving target detection under moving background conditions. Method (3) has a large amount of calculation and needs to improve the algorithm to meet real-time requirements. Method (4) is generally only limited by the recognition effectiveness. It is suitable for the detection of a specific type of target at a specific angle, and there is still a big gap between the application of the airborne photoelectric detection system for the detection of ground moving targets

Embodiment Construction
[0049] The present invention will be further described below in conjunction with accompanying drawing.
[0050] The photoelectric detection system of the ground moving target of the present invention, such as figure 1 As shown, it includes a camera, an image acquisition card, an industrial computer, a switch and a main control computer, wherein the industrial computer and the main control computer have control and data signal ports and video signal ports respectively, and the industrial computer It is connected with the two ports of the master computer through a switch. The video image signal captured by the camera is input into the industrial computer through the image acquisition card and stored as digital image data, and the moving target photoelectric detection image processing program is run to detect the moving target for each frame of image. The main control computer sends commands to control the work of the moving target detection system, and receives image processing...

The invention provides a to-ground moving target photoelectric detection system, and a data processing method and an image processing method thereof. The system comprises a camera, an image acquisition card, an industrial personal computer and a main control computer which are connected in sequence. The industrial personal computer and the main control computer are respectively provided with a control and data signal port and a video signal port. The two ports of the industrial personal computer and the two ports of the main control computer are connected by a switch. A to-ground photoelectric detection image can be acquired in real time. A moving target in an image can be detected in real time by the image processing method. The amount of calculation is small. A target detection result can be transmitted from the industrial personal computer to the main control computer through a local area network, and a result image can be displayed in real time. Moving target detection under a moving background is realized, and multiple-moving-target detection is supported.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a photoelectric detection system for an earth-moving object and an image processing method thereof. Background technique [0002] Ground moving targets (such as trains, cars, armored targets, etc.) have important military value. The detection and precision strike of ground moving targets is one of the main tasks of the Air Force. Strike and other tasks. [0003] The ground photoelectric detection image can obtain rich image information of ground targets and environmental intelligence. The ground moving target photoelectric detection system processes the image information, separates and marks the moving targets from the ground background. There are two main problems that need to be solved: one is that due to the movement of the carrier aircraft, the ground background in the photoelectric detection image will show a continuous reverse movement, so the image processing nee...
