摘要
由于超光谱图像数据量大,文章提出了一种能够对超光谱图像进行实时压缩处理的嵌入式系统。该系统采用cyclone3系列的EP3C16 FPGA为协处理器,完成数据缓存、逻辑控制以及外部接口的控制。以TI公司的TMS320C6455为中央处理器,实现超光谱图像的实时压缩处理。该系统具有高速的特点,通过实验证明可以对带宽为1 024 byte×129行×16 bit×200帧的图像数据进行快速传输并压缩。图像实时压缩后,通过ASI接口传输给下级系统。该系统稳定性好,结构具有可扩展可重建的特性。
Because the hyperspectral image data are numerous, a hyperspectral image embedded system capable of real-time compression process is put forward. The system uses cyclone3 series EP3C16 FPGA coprocessor to complete the data cache, logic control, and control of the external interface.It＇s TMS320C6455 as central processor to realise real-time compression of hyperspectral image processing. The system has a high-speed characteristics,the experiments show that the image data with bandwidth of 1 024 byte×129 lines×12 bit×200 frames can be transported and compressed. Image after a real-time compression, transferred to the lower system through the ASI interface. The system has good stability, the structure has a scalable reconstruction characteristics.
