摘　　要：文章给出了一个基于JPEG2000算法的实时红外图像压缩系统的设计电路,这个设计方案兼顾了图像压缩率和抗误码能力,适合在无线信道传输。该电路使用了专用的硬件压缩芯片ADV202和高速数字信号处理器TMS320C6416,解决了直接采用FPGA+DSP设计复杂、开发周期长的缺点。实验表明本文的设计方案工作正常,图像压缩的效果令人满意。A real-time infrared image compression system which is based on JPEG2000 standard is proposed.The system is suitable for wireless channels,because it has the high compression ratio and good error resilience.The dedicated video codec ADV202 and high-speed digital signal processor TMS320C6416 are used to carry out the algorithm.This way takes less developing time than the system using FPGA+DSP.The experiment shows this system works well,and the reconstruction image is satisfying.
