| Abstract: | The positioning precision is important in the processing of geometric parameters measurement technology of wheel tread. In this paper, a new method with no-contact measurement based on line structured light is given to solve this problem. Here traditional mechanical locating method is used as a rough reference. Moreover, some digital image processing techniques are developed for each of the key dimensions of measurement. According to the feature points (particularly, the key points that have not been worn) and lines extracted effectively on the wheel tread, precise positioning is realized. In this paper, the experiments show that the proposed method is feasible to implement noncontact measurement of the wheel tread, wheel flange thickness and rim width. It also ensures the accuracy of positioning and analyses the factors of measurement error. |
