Embodiment Construction

[0050] A target photoelectric search and detection method, the specific steps are:

[0051] The first step is to build a photoelectric search and detection device

[0052] Photoelectric search and detection device, including: infrared cooling camera, visible light camera, laser rangefinder, two-dimensional turntable, video processing equipment and system controller.

[0053] Infrared cooling camera, laser range finder, and visible light camera are installed on a two-dimensional turntable, with the optical axis of the infrared cooling camera as the reference, the optical axis non-parallelism between the visible light camera and the infrared cooling camera is less than 30″, the laser range finder and the infrared The optical axis non-parallelism of the cooling camera is less than 30".

[0054] The two-dimensional turntable includes two rotation mechanisms of the pitch axis and the azimuth axis.

[0055] The data interface of the infrared cooling camera is connected with the da...

Abstract

The invention discloses a target photoelectric search and detection method, which adopts a video processing device to eliminate trailing of shot images. The method comprises: translating the coordinate of a right image correspondingly to project to the plane of a left image, and thereby completing registration of adjacent cylindrical images of the two images; sequentially registering the whole set of images, thus achieving panoramic stitching of the image. Frame relative displacement value between the current frame and the previous frame is computed through computing the mean value of relative displacement values of macro blocks, the frame relative displacement value is used as a parameter to perform displacement compensation for the next frame when being interfered, and thereby shaking of the image is eliminated. The method solves the problem that the image shot by the existing photoelectric search and detection method is trailing, cannot achieve panoramic stitching and shakes in a high speed moving process.

Description

technical field [0001] The invention relates to a search and detection method, in particular to a target photoelectric search and detection method. Background technique [0002] Targets refer to small aircraft or airborne objects that fly at low or ultra-low altitudes, and have the characteristics of low flying altitude, slow flying speed, and small target characteristics. Due to the complex background of ultra-low altitude and the poor contrast of the target, the target is not easy to be detected. At present, in order to adapt to target recognition, locking and tracking in the day and night environment, the photoelectric search and detection devices used in the existing photoelectric search and detection methods are generally composed of infrared cooling cameras, visible light cameras, laser range finders, two-dimensional turntables and video processing equipment. . The existing photoelectric search and detection method is to shoot the target through the infrared cooling ...
