The invention discloses a tire pattern wear monitoring method, relates to the technical field of tire pattern wear, and solves the technical problem that the wear condition of a tire is evaluated only based on the concave-convex condition of the surface of the tire, so that the evaluation result is not accurate enough. The method comprises the following steps: acquiring a plurality of tire images, extracting a plurality of tire area images from the tire images, and dividing the tire area images into pattern groove areas and pattern surface areas; analyzing a pixel difference value and a depth difference value of the pattern groove region; analyzing a crack pixel proportion of the pattern surface area; based on the pixel difference value, the depth difference value and the crack pixel proportion, the wear index of the tire pattern is analyzed; analyzing the wear degree according to the wear index of the tire pattern; according to the method, the wear condition of the tire pattern is comprehensively reflected f
