Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a Zynq SOC-based infrared sensor control system and a self-service terminal. Background technique [0002] At present, the infrared imaging detection system obtains the infrared image of the target through the infrared detector, then preprocesses the infrared image and detects the target, and finally outputs the target image to the display screen for display observation. The infrared image processing system with good real-time performance and strong processing ability is the key technology of infrared imaging detection system. [0003] The typical architecture of the previous infrared image processing system is as follows: the infrared detector outputs the image to the FPGA (Field Programmable Gate Array, Field Programmable Gate Array), and the image preprocessing (non-uniformity correction, image enhancement, etc.) is completed in the FPGA, and then the FPGA The pre...
