Abstract
A method for measuring wheel alignment of a test wheel rotating about a z-axis using at least one camera and a processor includes obtaining a calibration point from a calibration image of a zero-offset wheel that is the same size as the test wheel and that rotates about the z-axis, obtaining at least one test image of the test wheel with the camera and a non-structured light source, and locating a measurement point in the test image. The measurement point coincides with a radius that the calibration point is offset from the z-axis and the angular displacement of the calibration point from the vertical diameter of the zero-offset wheel. The measurement point is further located based on a change of reflectivity between other points in the test image adjacent the measurement point.
