摘要
基于重构的方法通常用于工业视觉异常检测。它们依赖于模型的良好重构正态模式。然而,很难管理泛化的边界。模型泛化能力的强弱会直接影响重建的保真度,从而导致误报。针对上述挑战,我们提出了一种新颖的双分支重建异常检测方法来控制模型在两个维度上的泛化能力。它通过分辨率恢复和去噪分支将异常图像重建为正常图像。检测结果由它们的对比产生。此外,还引入了创新的信道调整模块,以改善各分支之间的信息交换。它使用多重扩张卷积来实现不同尺度的交互。模拟实验表明,在 MVTec AD 和 MVTec 3D-AD 数据集上,该方法优于大多数检测方法。在本研究的自生成汽车漆面划痕数据集上,该方法也显示出良好的效果。
DBAD: Dual branch reconstruction for industrial anomaly detection
Reconstruction-based methods are commonly used in industrial visual anomaly detection. They rely on a well-reconstructed normal mode of the model. However, it is difficult to manage the boundary of generalization. The strength of the model's generalization capability can directly affect the fidelity of the reconstruction, resulting in the occurrence of false positives. To address the above challenges, a novel dual branch reconstruction anomaly detection approach is proposed to control the model generalization capability at two dimensions. It reconstructs abnormal images into normal ones by resolution recovery and denoising branches. Detection results are generated from their comparison. In addition, an innovative channel adjustment module is introduced to improve information exchange between branches. It uses multiple dilated convolutions for interactions over different scales. Simulation experiments demonstrate that the method outperforms most inspection methods on the MVTec AD and MVTec 3D-AD datasets. It also shows good results on the self-generated automotive paint scratches dataset of this study.
