摘要: 针对现有截齿磨损测量方法存在过程繁琐、精度低和成本高等问题，设计了一种基于聚焦形貌恢复的矿用截齿磨损测量系统。该系统利用聚焦形貌恢复技术对采集的截齿顶部圆锥序列图像进行处理，获得截齿顶部圆锥三维形貌恢复图，在此基础上得到截齿顶部圆锥表面的深度信息，从而计算出截齿顶部圆锥体积，并结合差值法得出截齿磨损体积。测试结果表明，该系统测量精确度达97.68%。

Abstract: For problems of complicated process, low accuracy and high cost in existing pick wear measurement methods, a mine-used pick wear measurement system based on shape from focus was designed. The collected sequence images of cone on top of pick are processed through shape from focus technology, so as to obtain 3D shape recovery diagram of cone on top of pick. On this basis, depth information of surface of cone on top of pick is gotten, thus volume of cone on top of pick is calculated, and wear volume of pick is obtained by use of difference method. The test result shows that measurement accuracy of the system is 97.68%.
