Abstract

The main loads and forces on the tire are carried by its cord-rubber composites structure. The geometry of the cord rubber composites needs to be measured during the production of the tire to ensure its quality. In this paper, a vision-based high-speed cord-rubber composites measurement system is developed. The system can accomplish the high-precision calibration of the linear camera based on the Checkerboard calibration board. Integration of the infrared light source into the system to improve image quality at high-speed motion. Based on this, the edge extraction and geometric parameter calculation of the measurement object are realized by using the Hough transform and GPU acceleration algorithm. Finally, the system is verified by measuring a standard sample and comparing the measurement results with the standard values. The standard deviations of the two angle measurements are 0.004° and 0.014°.
