    摘要: A machine vision vehicle wheel alignment system configured to measure non-traditional vehicle wheel alignment angles and to determine dynamic behavior of a vehicle suspension system by observing optical targets or visible features, attached to points of interest on the vehicle body or vehicle wheels. The vehicle wheel alignment system characterizes the suspension geometry with respect to the body of the vehicle and to a rolling surface by measuring, in three-dimensions, points and/or angles on the vehicle body as well as the vehicle wheels, enabling measurement of specific non-traditional vehicle parameters, including wheel assembly braking force and lateral force moment arms.

    摘要: A machine vision vehicle wheel alignment system for acquiring measurements associated with a vehicle. The system includes at least one imaging sensor having a field of view and at least one optical target secured to a wheel assembly on a vehicle within the field of view of the imaging sensor. The optical target includes a plurality of visible target elements disposed on at least two surfaces in a determinable geometric and spatial configuration which are calibrated prior to use. A processing unit in the system is configured to receive at least two sets of image data from the imaging sensor, with each set of image data acquired at a different rotational position of the wheel assembly around an axis of rotation and representative of at least one visible target element on each of the two surfaces, from which the processing unit is configured to identify said axis of rotation of the wheel assembly.
