Streamlining tunnel maintenance management using surface images from overhead work! Capable of capturing at a maximum speed of 100 km/h.
The "Tunnel Lining Inspection System" enables the efficient management of tunnel maintenance using images of the lining surface. With high-resolution tunnel lining surface image acquisition technology and deformation extraction technology, it supports close visual inspections more quickly, accurately, and safely. It can capture images at a driving speed of 5 to 100 km/h without hindering road traffic. 【Features】 ■ Supports close visual inspections more quickly, accurately, and safely ■ Can capture images at a driving speed of 5 to 100 km/h ■ Adopts near-infrared LEDs to prevent distraction driving by not emitting light typically required during capture ■ Recognizes cracks as small as 0.2 mm with high-resolution lining surface images ■ Capable of extracting and visualizing deformations occurring on the lining surface *For more details, please refer to the PDF document or feel free to contact us.
