CHASSIS MEASUREMENT METHOD AND DEVICE

摘要

The invention relates to a chassis measurement method comprising the following steps: a chassis measurement system is provided that has four measuring heads (2, 4, 14, 16) which are disposed in a known position relative to each other and are each fitted with a monocular image capturing apparatus (22, 24, 26, 28); at least three geometric details of a wheel (6, 8, 10, 12) of a vehicle (1) standing in a starting position (A) are sensed using each of the four measuring heads (2, 4, 14, 16); a relative movement between the vehicle (1) and the measuring heads (2, 4) is performed from the starting position (A) into at least one other position (E) in which the position of the measuring heads (2, 4, 14, 16) relative to each other is known; the at least three geometric details of a wheel (6, 8, 10, 12) of the vehicle (1) standing in the other position (E) are sensed using each of the four measuring heads (2, 4, 14, 16); local 3D reconstructions are generated in order to determine the translational vectors (t1, t2, t3, t4), the rotational vectors (R1, R2, R3, R4), the turning angles of the wheels between the at least two positions (A, E), and the turning centers and the turning axes of the wheels (6, 8, 10, 12) from the sensed geometric details; a global scale for the measuring heads is determined by scaling the translational vectors (t1, t2, t3, t4) of the wheels (6, 8, 10, 12) such that the translational vectors (t1, t2, t3, t4) have the same length; and the camber, the individual track and/or the total track of the vehicle (1) is/are determined.
