Intelligent Eyes on Buildings: A Scientometric Mapping and Systematic Review of AI-Based Crack Detection and Predictive Diagnostics of Building Structures
This systematic review analyzes 146 Scopus-indexed publications (2015-2025) on AI-based crack detection and predictive diagnostics in building structures. It combines scientometric mapping with a focused technical review of 36 highly relevant studies. The research shows a rapid increase in activity after 2020, driven by deep learning and UAVs. While current methods focus on detection, predictive diagnostics and integrated SHM workflows remain underexplored. The study identifies key research gaps in data, methodology, and application areas.
Executive Impact Summary
Our analysis reveals that the rapid growth in AI-based crack detection offers significant opportunities for enterprise-level operational efficiency and safety. Early adoption of advanced deep learning models, particularly YOLO-based solutions, can lead to substantial cost savings and improved structural health monitoring. However, a fragmented research landscape and a lack of robust validation practices require strategic implementation to maximize ROI and ensure long-term reliability.

Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
Research activity significantly increased after 2020, peaking in 2024 with 44 documents. Early papers (2015-2017) have high average citations (171-213 per document), serving as foundational references, while recent papers (post-2020) show rapid uptake due to increased volume and shorter exposure time. China leads in publication volume (54 documents), but South Korea (70.92 cpp) and Turkey (107.50 cpp) demonstrate higher citation impact per publication.
Early research (2015-2020) focused on broad concepts like 'Deep Learning' and 'Structural Health Monitoring'. Post-2020, the field shifted to application-oriented themes such as 'Crack Detection' and 'Damage Detection', with 'Deep Learning' remaining dominant. Recent trends (2024-2025) highlight cutting-edge topics like YOLOv8, vision transformers, point cloud analysis, and GANs, indicating a move towards high-performance, multimodal, and real-time detection systems.
Most studies still rely on basic tasks like binary classification and object detection, with limited attention to higher-level reasoning or fully automated decision-making, such as predictive diagnostics or LLM-based reporting. While CNN-based models are prevalent, advanced transformer and hybrid models are emerging. The reliance on RGB imagery and simple annotations (image-level, bounding box) limits detailed structural interpretations, and evaluation protocols often lack robustness, with limited use of cross-validation or external testing.

Your AI Implementation Roadmap
A strategic phased approach to integrate AI into your building inspection and structural health monitoring operations.
Phase 1: Pilot & Data Collection Strategy
Initiate a pilot project on a specific building type to establish clear crack detection objectives and select appropriate data modalities (RGB, thermal, UAV). Develop a robust data annotation strategy, prioritizing bounding box and pixel-level masks for critical defect types.
Phase 2: Model Selection & Customization
Based on pilot results, select a deep learning model family (e.g., YOLO for speed, U-Net for precision). Leverage transfer learning with pre-trained models and fine-tune using your annotated dataset. Implement systematic hyperparameter optimization to ensure model robustness and generalizability.
Phase 3: Integration & Validation
Integrate the AI model into existing SHM or inspection workflows. Establish rigorous validation protocols, including external test sets and real-world field testing, to assess performance under diverse conditions. Begin exploring multimodal data fusion (e.g., RGB + thermal) for enhanced accuracy.
Phase 4: Scaling & Predictive Diagnostics
Scale the solution across your building portfolio. Develop capabilities for predictive diagnostics by analyzing crack progression over time. Investigate vision-language models for automated inspection reporting and integrate with maintenance decision support systems for proactive asset management.
