基于FPGA的红外图像预处理模块设计

摘要

介绍了一款基于FPGA的红外图像预处理模块.该模块使用流水线的方式完成了两点校正算法、一点校正算法、像元错位校正等功能.模块中嵌入了Microblaze和MPMC核,增加了一些人机交互接口,实现了一点校正算法系数的实时更新.该模块能以某一种格式接收红外数据,并以相同的格式输出;可以将其加入到一个系统中,或从一个系统中移除.%A FPGA-based infrared image pre-processing module is introduced. The module uses the pipeline to achieve the two-point nonuniformity correction,one-point nonuniformity correction,and pixel displacement correction. Microblaze and MPMC IP core are embedded in the module. The interface between human and machine is also added. Coefficient of one-point nonuniformity correction can be update in real time. The module can received infrared data in a certain format, and output it in the same format. It can be easily tailored to adapt to a certain infrared system.
