Motion Measurement on Rear Swinging Fork

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 synchronisation and trigger device for stroboscopic opservation of periodic events.


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