Problems solved by technology
However, if the processing unit is added, it will cause the disadvantages of larger system volume, increased power consumption, and large heat generation, which is not suitable for practical applications.
At the same time, due to the immaturity of the infrared focal plane market, the interface timing of the infrared focal plane has not formed a unified standard, so the single-signal processor DSP architecture that cannot easily provide various interface timings cannot well adapt to various infrared focal planes.

Description
Technical field: [0001] The invention belongs to the field of real-time processing of infrared images, in particular to a real-time infrared image processing system based on a single field programmable gate array FPGA, which is suitable for a large area array infrared detector with a high frame rate. Background technique: [0002] The advent of the forward-looking infrared system (FLIR) of Texas Instruments (TI) in 1964 marked the arrival of the era of infrared imaging. The infrared imaging system has strong anti-interference ability, good concealment performance, strong atmospheric penetration ability, and is suitable for many special occasions. However, due to its own characteristics and process limitations, the infrared focal plane has many differences between infrared image processing and ordinary CCD image processing, and special infrared image processing algorithms must be used to process it. For example, due to the defects of the production materials, the non-uniform...
