📝 摘要(中文)
由于训练配置的限制,传统的工业异常检测方法需要为每个部署场景训练特定模型,无法满足现代设计和制造的需求。相比之下,大型多模态模型在各种视觉任务上展现出卓越的泛化能力,暗示其在工业异常检测任务中的潜力。然而,尽管这些模型在文本领域拥有丰富的知识,但由于文本与视觉领域之间的模态差距,它们无法有效利用这些知识。为此,本文引入现有的工业异常检测方法作为视觉专家,提出了一种新的大型多模态模型Myriad,通过视觉专家的指导,增强模型对异常区域的关注,从而提升异常检测性能。大量实验表明,该方法在多个基准测试上表现优异,并继承了大型多模态模型的灵活性和指令跟随能力。

📄 摘要(原文)
Due to the training configuration, traditional industrial anomaly detection (IAD) methods have to train a specific model for each deployment scenario, which is insufficient to meet the requirements of modern design and manufacturing. On the contrary, large multimodal models~(LMMs) have shown eminent generalization ability on various vision tasks, and their perception and comprehension capabilities imply the potential of applying LMMs on IAD tasks. However, we observe that even though the LMMs have abundant knowledge about industrial anomaly detection in the textual domain, the LMMs are unable to leverage the knowledge due to the modality gap between textual and visual domains. To stimulate the relevant knowledge in LMMs and adapt the LMMs towards anomaly detection tasks, we introduce existing IAD methods as vision experts and present a novel large multimodal model applying vision experts for industrial anomaly detection~(abbreviated to {Myriad}). Specifically, we utilize the anomaly map generated by the vision experts as guidance for LMMs, such that the vision model is guided to pay more attention to anomalous regions. Then, the visual features are modulated via an adapter to fit the anomaly detection tasks, which are fed into the language model together with the vision expert guidance and human instructions to generate the final outputs. Extensive experiments are applied on MVTec-AD, VisA, and PCB Bank benchmarks demonstrate that our proposed method not only performs favorably against state-of-the-art methods, but also inherits the flexibility and instruction-following ability of LMMs in the field of IAD.
