Design and Research of Signal Processing System for Uncooled Infrared Thermal Imager

According to the large capacity and real-time features of an infrared image processing system, a modularized uncooled infrared thermal imaging hardware platform based on FPG8&ARM is designed The algorithm for correcting the non-uniformity in an infrared image is implemented on the FPGA. At the same time, the real-time communication problem among an acquisition module, a processing module and a control module is solved by using the gate array resource to configure a FIFO and a dual-port RAM. Practical applications show that the system is stable, high integrated and universal.
