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 from multiple dimensions, and the accuracy of evaluating the wear degree of the tire pattern is improved.

    本发明公开了一种轮胎花纹磨损的监控方法,涉及轮胎花纹磨损技术领域,解决了仅基于轮胎表面的凹凸情况来评估轮胎的磨损情况,导致评估结果不够精准的技术问题;本发明获取若干轮胎图像,并从中提取若干轮胎区域图像,将轮胎区域图像划分为花纹沟区域和花纹表面区域;分析花纹沟区域的的像素差值和深度差值;以及分析花纹表面区域的裂痕像素占比;基于像素差值、深度差值和裂痕像素占比,分析轮胎花纹的磨损指数;根据轮胎花纹的磨损指数,分析磨损程度;本发明从多个维度全面反映了轮胎花纹的磨损状况,提高了对轮胎花纹磨损程度评估的准确性。
