Problems solved by technology

[0004] The inventors of the present invention have found that the single-core DSP in the above-mentioned system needs to perform pre-processing encoding of digital image data and target search and tracking matching operation processing successively, which will lead to real-time processing of high-speed moving objects in high-resolution video images The ability is weak, so it is necessary to provide an image tracking system with stronger real-time processing ability

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0039] The inventor of the present invention considers that FPGA (Field Programmable Gata Array, Field Programmable Gate Array) can process relatively simple algorithms in parallel, and in an embodiment of the present invention, a large-scale FPGA is used instead of a DSP unit to preprocess and encode digital image data , and after the target search and tracking, and the digital image data of the marked target are output to the display for display according to the...

Abstract

The invention discloses an image tracking system comprising a video image acquisition module, an FPGA and a DSP, wherein the video image acquisition module is used for shooting video images and outputting digital image data. The FPGA is used for storing a present frame of digital image data which is output by the video image acquisition module through a digital signal output end thereof in to a first storage area of a storage via a data storage port of the FPGA. Digital image data of a previous fame stored in a second storage area of the storage is read through a data read port of the FPGA, and after the digital image data is subjected to gray scale transformation and median filtering, the data is output through a digital signal output end of the FPGA. The DSP unit is used for carrying out target searching and tracking according to the digital image data output by the FPGA. Through the utilization of the image tracking system and the image data processing method of the invention, capability of performing real time processing on the image data can be improved.

Description

technical field [0001] The invention relates to the technical field of image tracking, in particular to an image tracking system and an image data processing method thereof. Background technique [0002] Moving target detection and tracking is a process of detecting-recognizing-tracking targets in image sequences based on dynamic image analysis combined with image pattern recognition and image tracking methods. It is a very active field in the field of image processing and computer vision. branch. Among them, image tracking systems for moving target detection and tracking have been widely used in many fields such as industrial control, military equipment, medical research, and video surveillance. [0003] At present, the existing image tracking system structure is as follows: figure 1 As shown, it is generally composed of a video image acquisition module, a DSP (Digital Signal Processor, digital signal processor) unit, a memory, a D / A (digital to analog converter, digital ...
