Abstract

In modern warfare, well-equipped and trained snipers have become a mortal malady for the combat troops. How to accurately, timely and quickly find and destroy snipers becomes a research focus of national military experts. In order to effectively detect faint echo signal of cat-eye target and get the snipers’ position information in the detection area, a small size of dual-channel active laser detection system with monochrome and color Charge-couple Devices(CCD) is designed, which is based on the laser imaging principle of cat-eye effect, associated tests are also conducted. The dual-channel video capture can obtain more information of target area, while taking advantage of the high sensitivity of monochrome CCD will also provide more accurate grayscale information for the video image processing. In order to achieve the miniaturization of system, we choose a video processing board whose size is only 54mm*90mm as hardware platform to complete the algorithm. For verifying the feasibility and accuracy of algorithm, we ultimately build a full set of experimental detection system. The test results show that the system can accurately detect and mark typical cat-eye target from background under different distances, which verifies the rationality and validity of the proposed system and has certain practicality and promotion in the active laser detection system research areas.
