摘　　要：针对玻璃深加工行业中的异形玻璃定位问题,提出了一种具有共性的通用定位核心技术—图形定位解决方法。该算法主要采用的是由异形测量方法、CAD几何图形信息提取、轮廓曲线拟合和实体图形再现与相似等技术组合而成的方法,解决了异形玻璃加工中精确定位问题,并在玻璃加工系统中进行了实际应用。实际应用结果表明,该算法具有较高的定位精度和可靠性。Aiming at the graphics positioning of special-shaped glass processing, an image orientation and matching algorithm was presented, based on correlative matching method. The algorithm mainly involved contour measurement method, CAD geometries information extraction, contour data acquisition, curve fitting, graphics reproduction entities and similar technologies, the problems of special glass processing positioning were solved, and the algorithm was used in actual glass processing system. The actual applications proved that the algorithm have high precision and speed.
