Design of SOPC-based infrared image enhancement system

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.
