摘要: 针对轮胎钉孔检测以手工或X光所造成的辐射强、定位不准的问题,设计以机器视觉技术辅助高压放电的检测系统,有效检测钉孔并准确定位。采用大津法(Otsu)完成灰度变换后的图像二值化,并通过跟踪特定颜色的对象跟 踪器精确定位钉孔位置。经5组实际测试可准确地识别定位轮胎表面25 mm及以上直径通孔,检出率达92%

Abstract: For the problem that the nail hole detection of the tire is caused by manual or Xray radiation and the positioning is not accurate, a machine vision technologyassisted highvoltage discharge detection system is designed to effectively detect the nail hole and accurately locate the nail hole.The image is binarized after the gradation transformation is performed by the Otsu , and the position of the nail hole is accurately positioned by tracking a specific color object tracker.After 5 groups of actual tests can accurately identify the location of the tire surface diameter of 2.5 mm and above through holes, the detection rate of 92%.

Key words:tire hole detection; machine vision; grayscale transformation; otsu method
