Smartphones, which houses various onboard sensors and a camera, can be leveraged for structural health monitoring. In this paper, an iPhone’s camera coupled with a custom iOS app, D-Viewer, is employed for 3-D structural displacement monitoring. Based on the digital image correlation technique, the camera is used to track a circular target, and the app determines its in-plane, out-of-plane, and arbitrary direction displacements within the field of view. A series of static and dynamic experiments is conducted to validate the proposed technique.
