摘要
针对遥感图像分辨率的不断提高以及传输通道带宽限制的问题,提出了一种FPGA控制的专用JPEG2000标准算法集成电路的高帧频图像编码装置。原始图像数据通过LVDS接口接收,再经过乒乓缓存后传给压缩编码模块,极大地提高了传输速率。经过实际测试,该装置实现了对高帧频图像高压缩倍数的要求,降低了对传输通道带宽的要求,性能稳定可靠。
Aiming at the problem that remote sensing image resolution continues to increase and transmission channel bandwidth limit,a high frame rate image coding device for FPGA-controlled dedicated JPEG2000 standard algorithm integrated circuit is proposed.The original image data is received through the LVDS interface,and then transmitted to the compression coding module after being pinged by the ping-pong,which also greatly increases the transmission rate.After actual testing,the device achieves high compression ratio requirements for high frame rate images,reduces the bandwidth requirements of the transmission channel,and is stable and reliable.
