摘要： An improved method and system are provided for performing rolling runout compensation for vehicle wheel alignment. A plurality of sets of camber and toe measurements are acquired for a pair of vehicle wheels, each at a different, relatively small rollback angle between measurements; e.g., rolling the vehicle more than 0° and less than 180° from the last wheel position. Best fit sine waves are computed for each of the camber and toe measurements using the acquired data, and the best fit parameters are applied to compute runout at the current wheel angle. The computed runouts are subtracted from the measured camber and toe values to get true camber and toe values of the pair of wheels.

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： An apparatus and method for calibrating machine vision measuring systems that have more than one camera are disclosed. A first calibration target is mounted in a fixed relationship to a first camera of the machine vision measuring system. A third camera mounted in a fixed relationship to a second camera of the machine vision measuring system. Second and third calibration targets are mounted in a fixed relationship to one another and viewable by the first camera and by the third camera. A data processor is programmed to compute calibration of the first camera and the second camera, based on a position of the second calibration target relative to the third calibration target and based on a position of the first camera with respect to the third camera. The apparatus and method provide a way to continuously measure the positions of two or more cameras used in the measuring system, and to use such measurements to calibrate the system. If the cameras move with respect to each other, their respective positions are calculated and used in subsequent measurements. The apparatus and method enable a machine vision measuring system to be used without field calibration at the time of installation.

摘要： A method and apparatus for measuring the wheel alignment of a vehicle on a production line. In the measuring method, a wheel hub (55) having a plurality of hub bolts (56) for mounting a wheel to is rotated while displacements of the hub bolts are measured with displacement measuring sensors (73, 74). The wheel alignment is measured by calculating an angle of inclination (0) of the wheel hub on the basis of the measured displacements of the hub bolts.

摘要： The invention relates to a device for determining the geometry of a wheel and/or axle in motor vehicles in a measuring space using an optical measuring device, comprising at least one optical image recording device (2) to record the image from at least two different perspectives, a marking device (3, 4, 8) with a measuring characteristic array available or mounted on a wheel (5) and an evaluation device. The geometry of a wheel and/or axle can be determined in a simplified manner due to the fact that the marking device has at least one reference characteristic array (3) with at least three reference characteristics for each image recording position, the measuring area extends between the reference characteristic array(s) and the bottom of the measuring site, the position of the reference characteristics (4) in the measuring space is known in the evaluation device and the measuring characteristic array includes at least three measuring characteristics (8) for each wheel (5).
