2D Color Line Scan Camera

Crack and assets taken by 2D color line camera

Infrared Camera

Thermal image captured by infrared camera shows delamination behind the concrete surface. KURABO has developed this method available for pavement inspection.

Raw thermal image

Day time: Temperature of flawed area goes up faster than sound area.

Night time: Temperature of flawed area goes down faster than sound area.
