Traditional Chinese medicine(TCM)tongue diagnosis has obvious advantages,but its strong subjectivity,susceptibility to environmental influences,and lack of a unified standard greatly affect the objectivity and accuracy of diagnostic results,and it is difficult to integrate into the modern scientific system.Therefore,developing tongue diagnosis equipment to objectively and normatively extract tongue image information,and simulating human brain thinking to construct an objective diagnostic model of TCM tongue image-disease syndrome,and promoting the quantitative and intelligent research of TCM tongue diagnosis have become the trend of future development.This article reviews the research status and application prospects of TCM tongue diagnosis equipment,in order to provide methodological references and research ideas for the research and application of this field.
