The Retül Vantage 3D motion capture hardware is a marker based optical tracking system. It tracks Infrared (IR) light emitted by light-emitting-diodes (LEDs). The 4 glass filters on the front of the unit triangulate the position of the LEDs in 3D space.

Accuracy & Speed:The system individually tracks up to 15 markers without any loss of data rate. It currently tracks 8 markers on the cyclist’s body and 4 markers on the bike measuring tool. Each of these LED markers can be located in 3D space at an accuracy of 0.4 mm (.016 in) RMS (average) and 1.0 mm (.039 in) Maximum error. The system captures all 8 cyclist markers and delivers 3D coordinates, with timestamps, 18 times per second (18 Hz).

The system has full control over all LED flashes and thus discreetly knows which LED is which. This eliminates all post processing work and allows the measurements and reports to be delivered automatically in seconds. This allows the fitter to use the technology as an aid to the fit process and not a distraction.
