Real-time infrared imaging system based on FPGA

An infrared real-time imaging system has been developed for the uncooled infrared focal plane array (UIRFPA). By using this system, infrared video signal from UIRFPA is corrected and displayed. Taking advantage of the high speed and parallel computation of FPGA, it is used as the core part of the system to complete the functions such as sampling, data caching, nonlinear correction and image enhancement. Time is saved for back-end processing such as recognization and following by this system. The system is characterized by high integration. The result verifies the high performance of the system.
