英文摘要：

To implement the automatic inspection for characters on the tire mould surface,a character inspection system for tire mould was proposed based on machine vision. According to the features of the tire mould,the automatic inspection equipment was designed based on machine vision,and its working principle was introduced. Then,the corresponding image processing methods were designed mainly including image preprocessing,image location and character inspection etc. Finally,the feasibility and validity were tested by experiments,and the causes of errors were analyzed. The experimental results indicate that the automatic inspection system can inspect the characters on the tire mould surface with advantages of time-saving,high precision and fast detection.
