Steel coil head coordinate conversion method based on visual positioning

The invention provides a steel coil head coordinate conversion method based on visual positioning, and relates to the technical field of steel coil treatment processes. Comprising an expansion barrel suitable for winding a steel coil, a shearing mechanical arm is arranged on one side of the expansion barrel, the device further comprises an image processing unit, a plurality of image obtaining units facing the expansion barrel are arranged above the expansion barrel along the circumference, and every two adjacent image obtaining units have at least 20% of visual field contact ratio; and the image processing unit receives the image information of the image acquisition unit, and identifies, positions and converts the head coordinates of the steel coil, so that the shearing mechanical arm performs shearing action. By means of the scheme, automatic production of steel rings can be achieved, and the working efficiency is improved. 本发明提供了一种基于视觉定位的钢线圈头部坐标转换方法，涉及钢线圈处理工艺技术领域。包括适于卷绕钢线圈的扩桶，所述扩桶的一侧设置有剪切机械臂，还包括图像处理单元，所述扩桶上
