Paper Abstract

The continuous three-dimensional curved track measurement system (CTMS) based on vehicular strapdown inertial navigation system (SINS) and four odometers is firstly presented and validated in order to achieve rapidly the long span curve measurement for bridge health monitoring. The line-shape measurement is conducted on a viaduct. Experimental results show that the Z-axis and Y-axis error in comparison with total station for 180 m curved viaduct are 6.39 cm and 37.16 cm respectively. The system which will be further improved has potential applications for bridge health monitoring in the future.
