摘要： A vehicle wheel alignment system has a plurality of cameras, each camera for viewing a respective target disposed at a respective wheel of the vehicle and capturing image data of the target as the wheel and target are continuously rotated a number of degrees of rotation without a pause. The image data is used to calculate a minimum number of poses of the target of at least one pose for every five degrees of rotation as the wheel and target are continuously rotated the number of degrees of rotation without a pause. At least one of the cameras comprises a data processor for performing the steps of preprocessing the image data, and calculating an alignment parameter for the vehicle based on the preprocessed image data.

摘要： A vehicle wheel alignment system and method is provided for performing a rolling wheel axis of rotation and wheel spindle point calculation every time an alignment is performed. Embodiments include an aligner having a target fixedly attachable to a wheel of the vehicle; a camera for viewing the target and capturing image data of the target; and a data processor. The data processor receives the image data from the camera, and determines a vector pointing from the target origin to a wheel spindle point based on the captured target image data, when the vehicle is rolled while the wheel is on a substantially flat surface such that the wheel and target rotate a number of degrees. The data processor is further adapted to calculate an alignment parameter for the vehicle based at least in part on the wheel axis of rotation and the coordinates of the wheel spindle point.

摘要： A hybrid wheel alignment system and methodology use passive targets for a first pair of wheels (e.g. front wheels) and active sensing heads for another pair of wheels (e.g. rear wheels). The active sensing heads combine image sensors for capturing images of the targets with at least one spatial relationship sensor for sensing a relationship between the active sensing heads. One or both of the active sensing heads may include inclinometers or the like, for sensing one or more tilt angles of the respective sensing head. Data from the active sensing heads may be sent to a host computer for processing to derive one or more vehicle measurements, for example, for measurement of parameters useful in wheel alignment applications.

摘要： The invention relates to a method for determining the rotational axis and the rotating center of a vehicle wheel by means of at least two image capture units assigned to each other in position and situation during the journey of the vehicle, and by means of an analysis unit arranged downstream of said units, processing the recorded image information, taking into account multiple wheel features (10) present on the wheel or attached for the measurement, and by means of at least one bodywork feature present on the bodywork or attached for the measurement, wherein 2D-coordinates of the wheel features (10) and of the at least one bodywork feature are synchronously detected, and from these the 3D-coordinates of the features are calculated at certain time intervals and counted back to a previously established reference time point or corresponding reference position of the vehicle wheel, taking into account the distance traveled by the at least one bodywork feature relative to the reference position. To achieve measurement results that are as error free as possible, especially also when traveling on a real driving surface, it is provided that the paths of the wheel features (10) and of the at least one bodywork feature in the evaluation undergo an analysis with respect to the effects of at least one of the influencing variables, steering lock angle, steering motion, driving surface unevenness, and change of speed, and that from the analysis, correction factors or compensation functions are obtained for correcting the effects.

摘要： A method for compensating axial misalignment between wheel-mounted alignment sensors and an axis of rotation for an associated wheel. The method compensates sensors mounted to each wheel of a vehicle simultaneously, without requiring jacking of the vehicle wheels above a supporting surface, and which only requires wheel rotational movement over an arc of 60 degrees or less. The method utilizes measurements of a change in a wheel toe angle and measurements of a change in a wheel camber angle, during a measured rotational movement of the wheel, to identify sinusoidal variation in the respective toe and camber angles during the wheel's rotational movement, from which a measure of axial misalignment between the wheel-mounted alignment sensor axis of rotation and the wheel axis of rotation is identified.
