Vehicle contactless wheel centre, camber and tracking measurement - using mobile CCD cameras and illumination to produce symmetrical image or images.

摘要

One or more cameras (1) arranged to be mechanically movable are positioned and/or oriented to produce individually symmetrical images or images which are mutually symmetrical. One or more illumination devices (2) are arranged to be approximately or accurately symmetrical wrt. the symmetries evaluated in the images. The illumination devices can be moved with the camera or cameras. USE/ADVANTAGE - For measurement of position of centre of wheel, camber and/or tracking angle during vehicle mfr.. Eliminates e.g. long measurement times and complex designs.
