工业4.0推动了智能制造的快速发展,传统人工质检存在效率低、成本高和稳定性差等问题,而基于监督学习的工业图像异常检测方法高度依赖精确标注的异常样本,难以适应真实工业场景中缺陷稀少、多变的特点。相比之下,基于无监督学习的工业图像异常检测方法仅需利用正常样本建模正常产品的分布特征与内在模式,因而成为近年来学术界与工业界的研究热点。首先,围绕单类学习设定对基于无监督学习的工业图像异常检测方法进行系统综述,并依据异常分数来源将现有方法归纳为特征嵌入和图像重建两大范式,对相关研究的发展脉络与核心思想进行梳理;其次,在上述分类框架下,对两类方法的技术演进与研究趋势进行归纳,总结不同方法在特征表示、异常评分机制和定位策略等方面的共性与差异,并对现有研究成果的主要优势与局限进行综合分析,从整体上梳理当前基于无监督学习的工业图像异常检测方法的发展特点与研究重点;再次,归纳了该领域常用的基准数据集与评价指标;最后,从实际工业应用需求出发,对当前研究面临的主要问题进行概括,并对未来的发展方向进行展望,以期为该领域的后续研究与应用提供参考。
With the rapid advancement of Industry 4.0
Intelligent manufacturing has become increasingly important. Traditional manual inspection still suffers from low efficiency
high cost
and limited stability
while supervised learning methods rely heavily on accurately labeled anomalous samples
which are scarce and diverse in real industrial scenarios. In contrast
unsupervised industrial image anomaly detection learns the distribution and intrinsic patterns of normal samples only
and has therefore attracted growing attention from both academia and industry.First
a systematic review of unsupervised industrial image anomaly detection under the one-class learning setting was provided. Existing methods were categorized into two main paradigms according to the source of anomaly scores: feature embedding and image reconstruction
and the development of representative approaches was summarized.Second
based on this taxonomy
the evolution and research trends of these two paradigms were analyzed. The common characteristics and differences among existing methods in terms of feature representation
anomaly scoring mechanisms
and localization strategies were summarized to provide a structured understanding of current research.Then
commonly used benchmark datasets and evaluation metrics in this field were reviewed.Finally
the main challenges in current research were discussed from the perspective of practical industrial applications
and potential future research directions were outlined to facilitate further development and deployment of unsupervised industrial image anomaly detection methods.
