Optical analysis of low-floor tram drive motions

摘要

This paper is focused on special method for observation relative motions of bodies in space thanks to the optical analysis. In this case, relative motions are measured between the gearbox and the traction electromotor of low-floor tram. These components are marked by special markers. During the drive regime markers create trajectories, which are captured by cameras. All data is processed by system Qualisys. Each component gets own cartesian coordinate system and from them were found relative shifts and rotations between gearbox and traction electromotor.
