Resumen
This method can be applied to health monitoring of large-scale bridge structures, and the deformation of bridge structures can be monitored regularly and nondestructively using camera as a noncontact sensor. In order to improve measurement accuracy, a uniaxial automatic cruise acquisition device was designed to obtain the deformation of bridge elevation. The measurement points using the proposed method are denser than those of the traditional sensor measurement method. It can also detect abnormal deformation caused by the damage, and it is more efficient and easier to use.
