| 摘 要： | 针对飞机蒙皮腐蚀检测的问题,研究了一种自动检测铆钉周围腐蚀的算法。首先,提取腐蚀铆钉的周长、面积、质心、圆分度和最小外接矩形等几何特征,对提取特征进行简单的粗分类。在铆钉区域圆形参数的检测过程中,提出了一种基于铆钉周围腐蚀的蒙皮损伤自动检测方法,该方法对内距均值法确定铆钉中心和半径进行了改进。实验结果表明,该算法对飞机蒙皮特征提取方法简单,铆钉中心计算准确,中心偏离度提高到15.68%。

| Abstract: | Aiming at the corrosion testing of aircraft skin,a new automated recognition algorithm is presented in order to inspect the corrosion of rivet.Firstly,the geometry features such as the circumference feature,area feature,circular indexing feature,the minimum out-connected rectangle feature of the corrosion rivet are obtained by the algorithm.During the inspection of circular parameter around rivet area,an improved algorithm is presented which is based on the inner-distance mean value method,determining the c... |
