Design of real-time image processing system for IRFPA based on FPGA

Abstract

This paper presents a real-time processing system designed for infrared FPA. The real-time processing is a key technology in the infrared image processing system [1] . In this paper, the pre-processing and segmentation approaches are combined in order to achieve a good result from infrared images which have large noise, complex background and ambiguous target [2] . This design is a real-time IR image processing system based on Xilinx's VIRTEX-5, fully using of VIRTEX-5 FPGA’s high performing, the FPGA embedded Xilinx's MicroBlaze processor core, and high-performance pre-processing function modules. Data signals processed by FPA can be collected to carry out filtering calculation, and the LCD displays the image, user can control the system by touching screen real-time.
