摘　　要：提出了以JPEG2000图像压缩标准作为压缩算法,采用JPEG2000专用编解码芯片ADV202来实现遥感图像实时压缩系统的方案.该方案可以满足遥感图像压缩系统对实时性、低失真以及高压缩比的要求.测试结果表明,该系统工作稳定可靠,能够满足遥感图像压缩系统实时性的要求,图像压缩效果令人满意.The scheme of remote sensing image real-time compression system based on the algorithm of JPEG2000 image compression standard and the implementation of which is adopting the application specified integrated circuit for JPEG2000 image coder ADV202 is proposed. The JPEG2000 has advantages such as outstanding feature of rate-distortion, good subjective image quality and error resilience, so it could satisfy the demand for real-time, low distortion and high compression ratio of the remote sensing image compression system. The test result shows that this system works well and could run real-time and the reconstructed images are satisfying
