Description

Technical Field

[0001] This utility model relates to the field of road inspection technology, specifically a device for calibrating the area of ​​structural defects in roads, bridges, and tunnels. Background Technology

[0002] With the continuous development of transportation infrastructure, the mileage and number of highways in my country have increased, making tunnel inspection and maintenance increasingly demanding. Due to the combined effects of environmental load, geological conditions, and climate, tunnel surfaces may develop defects such as water seepage and spalling. Failure to address these defects in a timely manner can lead to unpredictable safety hazards. Therefore, accurate and real-time identification of tunnel defects is crucial for effectively developing maintenance strategies and further eliminating potential safety risks.

[0003] Currently, tunnel inspection vehicles are commonly used to detect the area of ​​surface defects in tunnels. Before measurement, these vehicles typically require calibration to ensure the accuracy and reliability of the results. Calibration methods at inspection stations usually employ standard plates as standard areas, which are only suitable for 2D cameras and not conducive to controlling the quality of 3D data. Currently, there is no relevant physical area calibration device to perform high-precision simulation of defect area parameters and provide calibration parameters for 3D intelligent tunnel vehicle inspection systems. Therefore, this paper proposes a calibration device for the area of ​​defects in road, bridge, and tunnel structures. Utility Model Content
