文摘
- •
Develop a combined measurement system for monitoring 6-DOF motions between two shields of double shield TBM.
- •
The measurement model combining monocular vision and inclinometers is derived.
- •
A calibration method for the transformation between the feature points and inclinometer is proposed.
- •
The proposed method mainly improves the measurement accuracy of pitch and roll angles.
