摘　　要：为解决红外热图像远距离无线传输中受带宽限制的问题,本文提出了在FPGA开发环境下实现图像JPEG压缩的设计方法。深入分析JPEG压缩原理及流程,寻找最佳压缩方案,结合Verilog语言在FPGA硬件平台上按照Top-down和模块化设计思想对一8×8图像单元进行JPEG压缩,将压缩后的数值与Win Hex工具对该图像所解析出的协议数据进行比对。实验结果表明本系统能够较好的完成红外灰度热图像JPEG压缩,提高图像远距离传输的速率与质量。Infrared thermal images are usually restricted by the bandwidth in the wireless remote transmission. In order to solve this problem, this paper introduces a design and implementation of JPEG image compression based on FPGA development. It analyzes the principle and process of JPEG compression to find the best compression scheme. Based on Top-down modularization an Verilog language, we completed the JPEG compression of an 8＊8 image on FPGA hardware platform. On this basis, we compared the compressed data with the analytic protocol data we got using Win Hex. It turns out that they are completely consistent. The experimental results show that the designed system can meet the demand of JPEG image compression and improve the speed and quality of image remote transmission effectively.
