基于拓扑反变的路面裂纹检测技术

Road surface crack detection technique based on topology contravariant

根据路面裂纹的多个本征属性,构建复杂数据集的度量空间,组成拓扑空间,推导路面裂纹原始空间到目标空间的拓扑反变关系。利用拓扑反变关系实现裂纹数据集的特征提取,为路面裂纹的识别奠定基础,并根据此方法设计出了系统的主要结构组成。通过实验分析了这种新的路面裂纹检测方法的去噪性能和识别能力。

This paper selected more than one intrinsic property of surface cracks,with construction of the metric space to complex data sets to form a topological space.Deduced topology contravariant relations and realized the characteristics of complex data sets,laid the foundation of extracting data sets characteristics.According to this method,designed the main structure of the system.At last,the experiments analyzed the de-noising performance and ability to identify of the new road surface crack detection method.
