Design and implementation of infrared thermal imaging system based on SOPC

In order to satisfy the demand for the domestic high-resolution infrared imaging technology in the field of border and coastal defence monitoring, a technical solution about infrared imaging and enhanced display based on GST817VM1E is proposed in this paper. Hardware platform is designed based on SOPC. Nios is used as the system controller working with the programmable unit to achieve the non-uniformity correction of uncooled infrared detector and infrared image such as two-point correction, blind element compensation, image subtraction background, autofocus and adaptive image enhancement, etc. The system supports the output of different formats and resolutions infrared video images such as PAL, Cameralink, DVI, etc. Experiments show that this solution can generate 14-bit gray level of 800 x 600 resolution infrared image, and the image frame rate can reach 60 frame/s, which satisfies the requirements of the border and coastal defence monitoring.
