Remote Real-Time Hyperspectral Video Acquisition Based on Zynq

摘要: 随着高光谱图像应用越来越广泛，其使用价值进一步被发掘，高光谱视频的需求也逐渐强烈。高光谱采集大多基于光栅分光原理，受微机电技术发展的推动，基于CMOS的高光谱传感器得以实现。本文采用Xilinx的Zynq处理器驱动CMOS高光谱传感器，通过Zynq内的FPGA构建DMA (Direct Memory Access)，实现了高光谱数据从光谱仪到终端的高速传输。当前大多数高光谱采集系统通过光谱仪采集数据，然后由上位机进行数据处理，对上位机的性能要求较高。本文所完成的高光谱采集系统由光谱仪采集并处理数据，终端通过浏览器即可远程实时查看高光谱图像，降低了对上位机的性能要求，具备重要的潜在应用价值。

Abstract: As the application of hyperspectral image becomes more and more widespread, its use value is further explored, and the demand of hyperspectral video is getting stronger. Most of the hyper-spectral acquisition was based on the principle of grating spectroscopy, however, with the development of MEMS technology, achieved with a CMOS-based monolithic integrated hyperspectral sensor. In this paper, we use Xilinx’s Zynq to drive CMOS hyperspectral sensors and build DMA (Direct Memory Access) through FPGA in Zynq to achieve high-speed transmission of hyperspectral data from spectrometer to terminal. The current majority of hyperspectral acquisition systems need to acquire data through the spectrometer and then process the data by the high performance host computer. The hyperspectral acquisition system designed in this paper collects and processes data by the spectrometer. The terminal can remotely view the hyperspectral images in real time through the browser, which reduces the performance requirements of the host computer and has important potential application value.
