Abstract

On the basis of the brief introduction to theory of uncooled infrared thermal imaging system and the infrared image processing algorithms, the key technologies to real-time image enhancement was studied, which driving a 160×120 Infrared Focal Plane Arrays (IRFPA) imaging system. In this article, an uncooled infrared thermal imaging system with real-time image processing and image enhancement was designed and developed, most importantly, a better result was achieved. Aiming at the Infrared Focal Plane Arrays (IRFPA), the hardware system used flexible design approach and efficiently developed tools on System-on-a-Programmable-Chip(SOPC)with two SDRAMs memories used as frame buffers. By this means, the 160 × 120 of IRFPA realized image acquisition. In this article, the structure of the system and the software realization of infrared images to achievement of the non-uniformity correction and image enhancement algorithm for parallel operation On the SOPC were described in details.The results showed that the design of SOPCbased real-time infrared image processing system could simplify system hardware and software design while ensuring the computing abilitiy. To the IRFPA imaging system of 160 × 120, processed infrared image quality was improved significantly to meet the real-time dynamic detection and tracking needs. Finally a system of uncooled infrared thermal imager with high price quality and convenient reconfiguration condition was implemented.
