Problems solved by technology

However, since the video processing of the device is mainly carried out in a dedicated video processing chip, it does not fully apply the parallel processing characteristics of the FPGA chip, and only the FPGA is used to control the entire system.

Abstract

A target detecting and tracking system using a background differencing method based on FPGA comprises a FPGA device, a SD card, an LED indicator light, a DDR2SDRAM, two seven-segment digital tubes, an LTM display screen and a minimum video detecting and tracking system, wherein the minimum video detecting and tracking system is embedded in the FPGA and is integrated in a SOPCbuilder environment with an AVLON bus as a standard. The target detecting and tracking system using the background differencing method based on FPGA is mainly used for detecting and tracking moving objects in static scenes. A target detecting and tracking method using the background differencing method based on FPGA comprises the steps of a. reading AVI format video files with the SD card, b. converting the AVI format video files into multiframe images, c. detecting and tracking the videos based on the images, d. obtaining the moving objects which are to be tracked, and e. displaying tracking results on the LTM display screen. Due to the fact that an FPGA platform is adopted by the system, the system is high in parallelism performance, and computing speed is improved. The target detecting and tracking method is good in tracking effect and adaptability, particle filter algorithm which is suitable for non-linear non-Gaussian dynamic models, and the target detecting and tracking system is similar with real scenes and is good in adaptability and high in tracking accuracy.

Description

technical field [0001] The invention belongs to the field of embedded technology, and in particular relates to an FPGA-based background difference method target detection and tracking system and method. Background technique [0002] At present, video tracking technology is widely used in military, security, transportation and other fields, and embedded video tracking system will also become a research hotspot. In the prior art, there are mainly the following methods for moving target detection and moving target tracking: [0003] (1) Adjacent frame difference method [0004] The moving area in the image is extracted by making a difference between several consecutive frames of images. The basic idea is to perform a difference operation on several adjacent frames of images, and determine the part whose difference is greater than a certain threshold as the moving target, and the other part as the background. . This algorithm has a small amount of calculation and is easy to i...
