Abstract

A structured light scanning system observes, interprets and provides structural feature size, position and movement data in automotive service equipment applications where such feature characteristics must be determined either preliminary to or ultimately for measurement of quantities affecting automotive performance, such as tire/rim assembly balance, runout and alignment or brake surface planarity and smoothness.
