A scale factor, which is a conversion factor between a pixel resolution of the image frame data and a distance resolution of real space, is calculated using image frame data taken at a predetermined first sample frequency of a stationary target outside the structure by a camera installed on the structure, and acceleration data measured at a predetermined second sample frequency by an accelerometer installed on the structure, over time. A vision-based displacement value of the structure is estimated using a feature point matching algorithm and the scale factor.

Ultrasonic vibrations are generated by a vibration exciting element attached to the structure, and first and second ultrasonic vibrations propagating in a tensile force direction and a direction orthogonal to the tensile force direction in the structure are detected using first and second vibration detection elements, respectively. The detected first and second ultrasonic vibration signals are converted into first and second digital signals.

The calculated absolute strain can be used to evaluate stability of the structure.
