AI Technical Summary
Traditional methods for locating tunnel defects increase in error as the device spends more time in the tunnel, resulting in lower accuracy for locating tunnel defects over long distances compared to those over shorter distances.
By establishing a three-dimensional coordinate system with the target point associated with the tunnel as the origin, the coordinate parameters of the defect location device in the target area are obtained, the relative position of the target defect and the defect location device is determined, and the relative position is converted into coordinate components in the three-dimensional coordinate system to achieve accurate positioning.
It improves the positioning accuracy of tunnel defects, especially over long distances, ensuring accurate location of tunnel defects.
