使用监控摄像机的光学运动跟踪技术已经应用于测量地震引起的运动和检测对内部元件的地震损坏，以降低建筑物中的风险。我们已经开发出了检测结构倒塌和内部构件倾覆的方法。进行了振动台试验，以评估光学系统的能力，以检测损坏。使用传统的摄像机监测两层框架结构和振动台上的矩形木块的运动。这项探索性研究的结果表明，光学测量在捕获小到大的变形和识别各种类型的地震破坏方面是有前途的。
Optical motion tracking technologies using surveillance cameras have been applied to the measurement of earthquake induced motions and detection of seismic damage to interior elements to reduce risks in a building. We have developed methods for detecting structural collapse and overturning of interior elements. Shaking table tests were carried out to evaluate the optical system’s ability to detect damage. The movements of two-storey frame structures and rectangular pieces of wood on the shaking table were monitored using conventional video cameras. Results from this exploratory study showed that optical measurements are promising in terms of capturing small to large deformations and identifying various types of seismic damage.
