| 摘 要： | 针对数字信号处理（Digital Signal Processing,DSP）＋现场可编程门阵列（Field Programmable Gate Array,FPGA）硬件架构存在硬件电路设计复杂、成本高等缺点,设计一套基于FPGA内嵌Nios Ⅱ软核的红外图像处理系统。系统包含Nios Ⅱ主控模块、A/D转换模块和红外图像预处理模块,实现了盲元补偿、两点多段校正、中值滤波和灰度变换等功能。验证结果表明,该系统具有体积小、成本低、开发周期短、实时性强等优点。

| Abstract: | According to the flaws of complicated circuit and high cost in DSP+FPGA structure,an infrared image processing system implemented in Nios Ⅱ embedded in FPGA is designed.The system includes Nios Ⅱ processor,A/D conversion and infrared image processing,and achieves the functions of blind pixel compensation,multi-point temperature correction,median filtering and gray transformation.The result shows that the system is small in bulk,low in cost,short in exploitation cycle and with strong real-time performance. |
