Design of multispectral remote sensing image compression system

In order to achieve the higher compression quality of multispectral remote sensing image,taking the JPEG2000 as the compression standard,the remote sensing image compression method is put forward,which used FPGA and special compression chip ADV212.With the ADV212 chip,high-quality real-time image compression for the large amount of remote sensing image data is realized through the wavelet transform and entropy coding.The system used FPGA to realize the image data input,the compression stream output,the image preprocessing as well as to control work mode of ADV212.Experimental results show that the system is low power consumption,low cost,simple and reasonable debugging,and has good compression effect.And the system meets the requirement of the multispectral remote sensing images high-quality compression ratio.
