Abstract
A wheel alignment method and device that includes an image pick-up unit that picks up an image of the measuring surface of a measuring plate so that at least a part of measuring marks drawn on the measuring plate are included in the picked-up image. A judging unit judges which measuring mark is included in the image picked up by the image pick-up unit. Based upon the relationship between the selected measuring mark and a measuring object position in the image picked up by the image pick-up unit, the position on the measuring plate corresponding to the measuring object position is calculated, thereby quickly determining the position of the measuring plate corresponding to the measuring object in a non-contact manner.
