Design method of adaptive dynamic range infrared image acquisition logic IP (Internet Protocol) based on FPGA (Field Programmable Gate Array)

The invention relates to an FPGA-based self-adaptive dynamic range infrared image acquisition logic IP design method, which comprises the following steps: caching an input infrared image according to frames, and carrying out dynamic range preliminary compression on the infrared image based on the gray level of the infrared image to obtain an image frame; performing bilateral filtering extraction on the image frame to obtain a base graph, and obtaining a detail graph based on the image frame and the base graph; carrying out gray level statistics on the base graph and the detail graph, then determining an effective dynamic range, and carrying out adaptive dynamic range gray level mapping; and performing weighted stacking on the mapped base image and the detail image to obtain a final enhanced image, thereby realizing detail enhancement of the high-dynamic-range infrared image, retaining more detail information of the image while compressing the dynamic range, and improving the infrared detection performance of
