【摘要】 在工业生产流水线上,工业机器人代替人工准确抓取和放置工件,很大程度上节约了劳动力,提高了生产效率,降低了成本^[1]。准确地获取工件位置信息,是定位系统的关键。采用最小外接矩形拟合法求解手机主板的实际位置,该方法用CCD相机拍摄工件图像,经过图像预处理,选择合适的阈值提取工件的轮廓,应用Graham算法求解工件轮廓的最小外接矩形,在建立的坐标系下求解出工件的实际坐标位置。实验结果显示该方法在一定的误差范围内满足工业机器人定位的要求。更多还原

【Abstract】 In this paper,using the minimum circumscribed rectangle fitting to solve the actual location of the mobile phone motherboard.This method get image artifacts with CCD camera firstly,through the image preprocessing,then select the appropriate threshold to extract the contour of workpiece,Graham algorithm solve the actual coordinates workpieces by solving the minimum circumscribed rectangle of the workpiece contour in the coordinate system established.更多还原
