Design and Application of an Infrared Image Super-resolution Reconstruction System

This paper presents an infrared image super-resolution reconstruction system based on FPGA and DSP architecture. The TI DSP （TMS320DM6467）with high-performance and Xilinx FPGA （VIRTEX-4）are used as the core processor. The DSP moduleis responsible for computing the target image reconstruction algorithm; the FPGA module is responsible for image preprocessing and communication with the host computer. DSP has advantages of flexible and speedy parallel computing.Through reasonable task scheduling, the task can be implemented by FPGA fast. Super-reso- lution algorithm combining with improved PCOS can get higher quality and stable reconstruction of infrared images. Application results show that the reconfigurable system is reasonable and practical.
