带有监视摄像机等光学设备的运动跟踪对于测量地震引起的运动特别强大。我们提出了一种基于视觉的运动跟踪系统，以提供额外的安全功能来检测内部元素的地震破坏，从而降低建筑中的风险。进行了振动台试验，以评估该系统使用传统摄像机检测结构倒塌和内部构件倾覆的能力。这项探索性研究的结果表明，基于视觉的测量在捕捉从小到大的变形和识别各种地震破坏方面很有希望。
Motion tracking with optical devices such as surveillance cameras can be particularly powerful for measuring earthquake induced motions. We propose a vision-based system with motion tracking for providing additional safety functions to detect seismic damage to interior elements and thus reduce risks in a building. Shaking table tests were carried out to evaluate the system's ability to detect structural collapse and overturning of interior elements using conventional video cameras. Results from this exploratory study show that vision-based measurements are promising in terms of capturing small to large deformations and identifying various kinds of seismic damage.
