What is Pavement Distress Detection?
Pavement Distress Detection uses computer vision and deep learning to automatically identify cracks, potholes, and surface defects in asphalt pavement images.
Researchers apply CNN-based models like U-Net and DeepLab, along with traditional filters such as Gabor, to segment distresses from road imagery. Key papers include Koch and Brilakis (2011, 553 citations) on pothole detection and Oliveira and Correia (2012, 502 citations) on crack characterization. Over 10 major papers since 2011 review methods from segmentation to attention-based networks.
Why It Matters
Automated detection enables proactive road maintenance, reducing accidents and costs; Oliveira and Correia (2012) system minimizes human subjectivity in inspections. UAV multispectral imaging by Pan et al. (2018, 200 citations) supports large-scale monitoring. DMA-Net by Sun et al. (2022, 221 citations) improves segmentation accuracy for better service life prediction.
Key Research Challenges
Noise and Lighting Variability
Crack images suffer from irregular lighting and noise, complicating segmentation; Lau et al. (2020, 259 citations) note feature engineering needs for U-Net. Traditional methods like Gabor filters by Salman et al. (2013, 279 citations) struggle with low-contrast defects.
Lack of Labeled Data
Supervised models require extensive annotations, which Oliveira and Correia (2012, 502 citations) address with unsupervised approaches. Recent reviews by Kheradmandi and Mehranfar (2022, 362 citations) highlight data scarcity in diverse conditions.
Real-Time Processing Limits
Deploying deep networks on mobile devices faces computational constraints; Cao et al. (2020, 284 citations) review efficiency issues. Attention mechanisms in Sun et al. (2022, 221 citations) aim to balance accuracy and speed.
