Hardware Design And Implementation Of Infrared Image Processing System Based On FPGA

With the development of computer technology and digital signal processing technology, infrared imaging system has been widely used in various fields. Demanding on real-time and stability of infrared image processing system is also getting more strict and urgent, which brings a severe challenge to the high performance image processing hardware platform.To meet requirements of the image processing system in big data processing, compact volume size, and low power consumption, a real-time infrared image processing hardware system based on a FPGA logic control with DSP as the core processing is proposed in this thesis.The main work of this paper includes the following issues. Firstly, this paper introduces the development, classification of the infrared image processing technology. Following the selection of the devices according to the general requirements of task is presented, The infrared image processing system and the hardware structure are introduced. The hardware circuit design of each functional module,parameters selection of each module and connection methods of there are described detailedly. These major modules include image input module, FPGA control module, storage module, image output module, power module and clock module. Secondly, this paper introduces the PCB design and its problems which are easy to appear in the circuit design and the matters needing attention. Thirdly, the logic designs based on FPGA are given out, including image input module, SRAM module, histogram statistics module, and image output module.The main advantages of the infrared image system are real-time and stability.The running speed of the system hardware to meet in the DSP and FPGA to realize signal processing algorithms, so as to ensure the real-time of the system; the real-time performance and stability of the system are verified by the functional test of the actual circuit and the QUARTUS simulation. So as to better satisfy the real-time infrared image processing requirements,to achieve the target.
