The invention discloses an automatic recognition and correction method of structural part broken surface defects based on an attributed adjacency graph. The method comprises the following steps of definition of the broken surface defects, recognition of the broken surface defects and automatic correction of the broken surface defects. According to the method, the broken surface defects of mathematical model surfaces of complex structural parts can be effectively recognized and corrected, the method has the advantages of accurate recognition result, high efficiency, effective correction resultand the like and can be applied to quality detection and correction of three-dimension design models of the complex structural parts, accordingly, the efficiency of quick numerical control programmingis improved, and the workload of working personnel is remarkably reduced. 本发明公开种基于属性邻接图的大型复杂结构件碎面缺陷自动识别与修正方法，其步骤如下1)碎面缺陷定义；2)碎面缺陷识别；3)碎面缺陷自动修正。本发明能有效识别并修正复杂结构件数模表面的碎面缺陷，具有识别结果正确、效率高、修正结果有效等特点，可用于复杂结构件三维设计模型质量检测与修正，以提高快速数控编程的效
