Abstract

The invention relates to an FPGA implementation method for ground-air image tracking. The method first decodes the CCD input image, and compares the same area specified in two adjacent frames of images in the FPGA to obtain target motion information; directly extracts the information through the FPGA. Target center, motion offset and speed, and determine the steering and size of the CCD pan / tilt (or turntable) according to the target center and motion speed, and realize ground-to-air target tracking; the present invention directly adopts FPGA to process all image acquisition and tracking calculations, It realizes the fast processing and tracking of the image, does not need other core processing units such as DSP, and improves the processing speed.

Description

An FPGA Realization Method for Ground-Air Image Tracking technical field The present invention relates to a kind of ground-air target tracking method, in particular to a kind of FPGA implementation method of ground-air image tracking Law. Background technique Along with the growth of airport traffic flow and the complication of operating conditions, the ground monitoring of aircraft is very important to airport safety management. Playing an increasingly important role, image-based aerial target tracking systems are immune to radio interference and can be integrated with radar, red External, laser, etc. are used for airport ground surveillance and aircraft take-off and landing management, making up for the radar's inability to search and track normally in its blind spots The defect of the target; the current ground-air tracking mainly adopts the contrast analysis method, the optical flow analysis method and the correlation tracking method. light flow Based on the a...
