At present, at home and abroad have developed a wide range of non-contact measurement of three-dimensional contours of these laser triangulation method because it is simple to measure speed, real-time processing power, the use of flexible, adaptable, in robot vision , In-kind profiling, auto-processing, industrial areas detecting and so on a wide range of applications.In this paper, the characteristics of the tire tread, using laser triangulation and linear laser measurement program, the realization of tires on the surface of the measurement. In this paper, the system and test the principle, structure, systems Mathematical models of the system error was introduced and analyzed. In the course of data processing, through collected images of the surface of the tire test, chose the Wiener filter to the image of the pre-through least squares, light extraction structures such as the center of the digital image processing techniques to improve the system Measurement accuracy.In order to meet the demand for industrial applications, the paper proposes a system of image processing, the image processing system in the digital signal processor (DSP) control, without any computer system can be completed by imagery of the acquisition, conversion, processing and display, and so on Related work, the system has a small, low-cost, reliable work, and other advantages, particularly suitable for industrial use at the scene.
