摘　　要：轮胎成型机胎体帘布偏移是造成车辆轮胎运行不平稳、出现跳动的主要原因。本文利用机器视觉实现了胎体帘布偏移量非接触式在线检测,为保证轮胎平稳运行奠定了基础。在详述了胎体帘布偏移量视觉检测方法原理的基础上,论述了数据处理方法和偏移量计算方法,并利用获取的数据点云重建胎体帘布表面轮廓着色点云图。试验结果表明,该视觉检测方法可以较好地完成胎体帘布偏移量测量,为轮胎生产过程提供精准把控,保证成型轮胎质量。The offset of casing ply is the main reason forunstable running and beating of military and other vehiclestires.Using machine vision to achieve the casing ply offset non-contact on-line inspection and lay the foundation for tire smooth running.On the basis of elaborating the principle of visual inspection method for offset of casing ply,discuss the data processing and the offset calculating method in detail,and use the acquired data point cloud can reconstruct the casing ply surface profile color point cloud map.The results show that the visual inspection system can well complete offset of casing ply measurement,and can provide accurate control for the tire forming process to ensure the quality of molded tires.
