Problems solved by technology

The quality of target recognition and tracking has a lot to do with the band width of the target signal collected by the camera. The existing video tracking system generally only has the video processing capability of one camera, which is either visible light or infrared, and the target recognition ability is poor. low stability

Abstract

A dual mode video target identification tracking system belongs to a video image processing technology in the electronics field. The system comprises: a first interface conversion module, a first field programmable gate array (FPGA), a first data memory, a first digital signal processing (DSP), a first program memory, a second interface conversion module, a second FPGA, a second data memory, a second DSP, a second program memory, a serial port module and a signal conversion module. By using the system, video signals of an infrared camera and a visible camera can be simultaneously collected and the two DSPs are integrated. The first DSP is responsible for processing image data of the visible camera and the second DSP is responsible for processing image data of the infrared camera. A processing result of the visible camera can be acquired from the first DSP and final target miss distance can be determined optimally through a serial port output tracking result. In the invention, the video signals of two waveband cameras can be simultaneously processed, the two DSP can form mutual communication and the optimized determination can be performed to the two results so that the stable calculation result can be obtained.

Description

technical field [0001] The invention belongs to the video image processing technology in the field of electronics, and relates to a dual-mode video target recognition and tracking system. Background technique [0002] Video tracking system is a real-time image processing system with the ability to identify and track targets in video images. It is widely used in military and civilian fields, especially military, such as optical automatic tracking system, missile automatic tracking system, general They are all used in conjunction with the servo control system. The target position (that is, the amount of miss) is obtained through calculation, and the output is sent to the servo control system for automatic tracking of the target. The quality of target recognition and tracking has a lot to do with the band width of the target signal collected by the camera. The existing video tracking system generally only has the video processing capability of one camera, which is either visibl...
