Study of uncooled infrared image processing system based on Nios Ⅱ

A miniaturized uncooled infrared image processing system is designed by adopting the structure of Field Programmable Gate Array (FPGA) embedded with NiosⅡ processor instead of Digital Signal Processor (DSP) +FPGA structure. A signal processing method based on pipelining model is proposed and applied in the system with the hardware and software development tools of NiosⅡ embedded processor. As indicated by the experiment result, the system can process the uncooled infrared image in real time. It has the merits of good performance and small volume.
