Abstract (English): Because of the geometric complexity, it is hard to get accuracy parameters by traditional manual measurement. The image processing was used to filter the image and enhance the image edge. The random error caused by inner holes and edge burr was reduced, and the geometry features of projected area, contacted area, length, width, ratio and width of pattern were obtained. By the scanning image of tire footprint, a precise reconstruction of tire footprint was realized, and a fast measurement of geometric parameters of footprint was achieved to check the accuracy of system by test. The results show that the relative error of system is about 1.00%,and the system has good applicability for different tire types and color inks. [ABSTRACT FROM AUTHOR]
Abstract (Chinese): 由于轮胎接地印痕几何复杂,传统手工测量难以提取准确几何信息量.为此,将图像处理技术应用到轮胎接地印痕几何量提取领域,提出一种基于图像处理技术的轮胎接地几何特征提取方法,并开发了相应的软件系统,基于轮胎接地印痕的扫描图像,精确重构了轮胎接地印痕.通过图像处理技术对获取的接地印痕进行滤波及轮廓增强处理,减少内部孔洞及边缘毛刺导致的随机误差.提取包括投影面积、接触面积、印痕宽度、印痕长度、海陆比和花纹间隙宽度在内的几何信息,实现了印痕几何参数的快速测量,并通过试验验证了本系统的测量精度与通用性.结果表明:系统测量相对误差为1.00%左右,对不同型号轮胎及不同颜色墨水获取的接地印痕均有良好的适用性.
