Rethinking Infrastructure Inspection as Image Difference Classification: A Traffic Sign Case Study
arXiv:2606.06375v1 Announce Type: new Abstract: Digital twins (DTs) allow the digitalization of road infrastructure inspection, though this is hindered by limited annotated data. This work exploits the relational nature of continuous asset condition monitoring to reformulate image-based defect detection as image difference classification (IDC) to reduce data reliance. This was evaluated in a case study on low-resource traffic sign inspection with different IDC classifiers using a newly-curated, high quality dataset. Results indicate that the instruction-based classifier outperforms encoder-bas
The proliferation of digital twin technology and the increasing demands for efficient infrastructure maintenance are driving innovation in AI-powered inspection methods.
This development proposes a novel approach to defect detection, reducing reliance on extensive annotated datasets, which is a major bottleneck for AI adoption in many sectors.
The method of infrastructure inspection shifts from labor-intensive manual reviews or data-heavy AI models to more efficient, data-light 'image difference classification'.
