Using multiple digital video cameras, we filmed the tunnel lining while driving, visualizing the condition of the concrete surface!
This system captures images of the tunnel lining while driving using multiple digital video cameras, visualizing the condition of the concrete surface to accurately detect deterioration and deformation such as cracks and water leaks. The obtained image data is converted into a deterioration and deformation development diagram, which can be input into our developed "CrackDraw21," enabling detailed equipment management such as condition verification and analysis of deterioration and deformation characteristics. This system can be utilized for advanced maintenance management, including condition verification of infrastructure and analysis and evaluation through deformation screening. **Features** ◇ Significant reduction in inspection work time Shooting speed: up to 80 km/h ◇ Improved safety of inspection work and working environment (can shoot at high speed without lane restrictions) ◇ Highly reliable development diagrams (can be effectively utilized even when conducting visual inspections separately) ◇ Crack width: shooting resolution and speed can be set according to inspection specifications (width from 0.2 mm) ◇ High-precision image creation through mobile 3D measurement before shooting ◇ Supports the preparation of reports for local governments (CrackDraw21) *For more details, please refer to the PDF document or feel free to contact us.*
