    摘要： An improved image sensing wheel alignment system for calculating vehicle wheel alignments having a detector array for receiving an input image containing vehicle wheel alignment information. An image sensor controller controls the detector array to receive the input image during an acquisition period, the image sensor controller examining signals from the image detecting elements individually at a plurality of times during the acquisition period to determine exposure levels for image detecting elements. An output image from the image detecting elements at the end of the acquisition period contains wheel alignment information for use in calculating vehicle wheel alignments.

    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. 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.

    摘要： A method and apparatus for determining the alignment of a vehicle wheel using an optical target attached to the vehicle wheel, the optical target having a dimensionally stable shape and a plurality of visible features defining target elements arranged in a known geometric and spatial configuration relative to each other across at least two surfaces. A two-dimensional image of the optical target is acquired by an imaging system to detect a plurality of target element images corresponding to the plurality of target elements. A spatial orientation of the optical target and an alignment of the vehicle wheel is then determined from the plurality of target element images and the known geometric and spatial configuration of the plurality of target elements on the target surfaces.

    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.
