Aiming at the problem of existing monocular vision measuring technique in synchronously measurement for structural 3D vibration and rotation parameters measurement, a series of novel vision displacement-sensitive fringe pattern (DSFP) based dynamic measurement methods were proposed. Multi-dimensional and multi-parameter synchronous measurement for non-rotating structural 3D displacement, rotating shaft 3D displacement, rotation angle and rotation speed could be realized by using the novel DSFPs as vibration displacement or rotation angular displacement sensors and using a high-speed camera as a detector. The evolution and measurement principle of different DSFPs were well descried. The feasibility and accuracy of the vision DSFP-based measurement methods for the measurement of non-rotating structural 3D displacement, rotating shaft 3D displacement and rotation parameters were verified by experimental results, which provides a series of measurement solution for structural condition monitoring and faults diagnosis.
