An intelligent identification method for acupuncture point reaction zone combined with infrared thermal imaging

Abstract

This invention relates to the field of image analysis technology, specifically to an intelligent identification method for acupuncture point reaction zones combined with infrared thermal imaging. The method acquires time-series infrared thermal images of the target area and acupuncture reference points; based on the spatial gradient and temporal temperature variation characteristics of pixels, a diffusion feature matrix is ​​constructed to accurately quantify heat transfer resistance; the diffusion feature matrix is ​​mapped to a heat transfer cost network, the cumulative transfer cost is calculated, and the topological connection relationship of the minimum cost path tree is determined; based on the topological connection relationship, path backtracking statistics are performed to generate a path overlap feature field; utilizing the difference between the convergence characteristics of meridian heat transfer and the radiation characteristics of traumatic heat diffusion, combined with the cumulative transfer cost, the heat transfer skeleton line is accurately extracted; based on the skeleton line, a dynamic active state signal reflecting the patency of the meridians is obtained. This invention effectively removes interference from traumatic thermal spots, achieving accurate identification and quantitative evaluation of meridian sensing trajectories.
