A TV search and detection method for low, slow and small targets

Abstract

The invention discloses a television search detection method for a small slow low-altitude target. According to the method, an exposure sensor is used for detecting next frame view field brightness of an optical search camera so that the exposure factor of the optical search camera can be adjusted and exposure time of the camera can be controlled to achieve optical adjustment under the condition of large contrast of background brightness. By means of deconvolution compensation and transferring through control over moving speed of an electric charge matching turntable in an image sensor, shot image streaking can be eliminated. Searching and target tracking can be performed on all ranges or key precaution areas which are covered by a television search detection device through setting of a panorama mode or a custom locale mode. Finally, the small slow low-altitude target can be identified, locked and tracked in daytime environment. By means of the method, problems of streaking of images which are shot by the television search detection device, image blurring caused by failure of timely optical adjustment, and failure of area key detection can be effectively solved.

Description

technical field [0001] The invention relates to a target search and detection method, in particular to a low-slow and small target TV search and detection method. Background technique [0002] Low-slow and small 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 poor target contrast, low, slow and small targets are not easy to be detected. At present, in order to adapt to target recognition, locking and tracking in the daytime environment, the TV search and detection device generally consists of an optical search camera, a laser range finder, a two-dimensional turntable and an image processing module. There are some deficiencies in the existing TV search and detection methods. When the rotation speed is fast, the image captured by the TV search and detection device will appe...
