The video shows the application of a stereo image correlation (phase synchronized) for a three-dimensional displacement measurement or movement analysis (Vic-3D).
The used stereo camera system is based on two 5 Mpixel cameras with a frame rate of 6Hz (at full resolution) in combination with the isi-sys synchronization and trigger device for stroboscopic observation of periodic events.

Four measurement areas (hydraulic cylinder — below, wheel hub — left, swingarm — middle and linear unit — right above) with speckle patterns were monitored for the evaluation. The vector arrows represent the current displacement state.
