Abstract

Displacement measurement plays a crucial role in various engineering applications, particularly in the field of structural dynamics and vibration analysis. In recent years, vision-based methods have emerged as a promising and non-contact alternative for measuring the displacement of isolation bearings. This comprehensive review presents an in-depth analysis of vision-based displacement measurement techniques applied to isolation bearings, highlighting their advantages, challenges, and future prospects. The result shows that the horizontal displacement time history of the isolation bearing obtained by this method is almost the same as the result obtained by the displacement meter whether the camera is moving or fixed. However, compared with the results measured by the displacement meter, the absolute error of the peak horizontal and vertical displacements are both less than 1 mm, which indicates that the proposed method can be used in displacement monitoring under long-term load and earthquake action of isolation bearing.
