| 摘 要： | 为了提高工业CT图像处理系统的处理效率，对其边缘连接和直线拟合方法进行了优化研究。对于边缘连接，根据边缘间隙大小决定连接方式：对小间隙直接用直线填充;对较大的间隙，采用基于模糊判决的边缘连接法计算边缘间总隶属度最大的一条路径，并将其填充。对于直线拟合，先用二元素特征点法提取轮廓特征点，再采用改进的集合求交直线识别方法将特征点间的线段拟合。通过实例验证了优化方法的正确性。

| Abstract: | Optimization methods of edge linking and linear fitting are researched to improve the efficiency and accuracy of the industrial computed tomography (CT) image processing system. For edge linking, the linking mode is decided by the size of the gap between edges. The smaller gap is linked with a line and the bigger gap is linked with an optimal path calculated by fuzzy theory. For linear fitting, feature points of the contour are obtained, and then an improved method of set intersection operation for line recognition is adopted to fit the feature points. The application proves that the optimization methods are effective and feasible. |
