摘要
高光谱图像数据量庞大,难以实现实时无线传输,严重制约了高光谱图像数据传输处理的实时性。本文自主研制Zynq平台微型高光谱仪,对快照马赛克面阵高光谱传感器采集到的特定高光谱图像数据进行无损预测压缩,并用FPGA实现。其压缩比为1.7至2之间,增加了高光谱图像数据无线传输的能力,扩展了微型高光谱仪的应用范围。
The huge amount of hyperspectral image data makes it difficult to realize real-time wireless transmission of hyperspectral image data. And it will seriously restrict the real-time nature of the hyperspectral image data transmission processing. This article independently develops a Zynq platform Micro-hyperspectrometer. Collecting the specific hyperspectral image data through the snapshot mosaic area array hyperspectral sensor, we can predict and cdcompress the data which is subjected to FPGA. Its compression ratio is between 1.7 and 2, which increases the ability of wireless transmission of hyperspectral image data. And it can greatly expand the application range of the micro-hyperspectrometer.
