Abstract: A method for contactless measurements of a vehicle wheel assembly by acquiring a sequence of images as the vehicle wheel assembly moves within a projected pattern of light. Images of the vehicle wheel assembly are acquired and processed to identify the portions of the images corresponding to the wheel assembly, such as by recognition of the wheel rim edge. The identified portion of each image is cropped and a resulting point cloud of data rotational aligned by an optimization procedure to remove the effect of wheel translation and rotation between each image, as well as to identify a center of rotation and amount of rotation for each image which yields a best-fit result. Superimposing the resulting point clouds produces a generated image with a high density of data points on the optimally fit surfaces of the wheel assembly, which can be used to further refine the axis of rotation determination.

Abstract: A method for detecting the occurrence of deviations from level, straight-line rolling movement of a wheel assembly across a supporting surface during a rolling compensation procedure associated with a vehicle wheel alignment measurement or inspection system by identifying changes in measurements or calculated parameters associated with the wheel assembly which would be unchanged during an ideal level and straight-line rolling movement. Identified changes in the measurements or calculated parameters are evaluated to either warn an operator of the occurrence of a deviation, or to generate a correction factor to account for at least a portion of an effect which the deviations introduce into compensation calculations or subsequent wheel alignment measurements or service procedures.
