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.

1. A measuring plate attached to a wheel so that an origin thereof corresponds to a rotational center of the wheel of a vehicle being measured, comprising:a measuring mark area which is formed in an area surrounding and containing the origin, and provided with measuring marks; and a distance measuring area on the measuring plate which distance measuring area is optically uniform and extends along an axis that is coaxial with a longitudinal direction of the vehicle being measured, said distance measuring area being irradiated by a measuring light emitted from a measuring unit, said measuring mark area containing: a first reference mark having center coordinates that are the origin of said measuring plate; a plurality of second reference marks having center coordinates that are located at intersections of first virtual lines in parallel and second virtual lines in parallel; and a plurality of correction lines which are in parallel with either the first virtual lines or the second virtual lines, and are situated at uniform intervals.
