The Tunnel Imaging Inspection Device is installed on an inspection vehicle and employs digital high-definition imaging and machine vision technology. By using advanced high-resolution, low-noise, and low-distortion image sensors, it achieves high-speed real-time acquisition of tunnel surface images. It features continuous high-definition imaging of tunnel lining surfaces along with automatic defect recognition and early warning functions. The device enables real-time panoramic inspection of tunnel conditions, promptly detecting defects such as damage, spalling, water seepage, and cracks on the tunnel lining surface. This guides maintenance personnel in performing tunnel upkeep and repair, ensuring safe operation of the line.
