    摘要: A mobile system and method of calibrating an ADAS sensor of a vehicle by aligning a target with the sensor, where a transport vehicle is equipped with a target adjustment stand for transporting to the vehicle, which is initially nominally positioned in front of the target adjustment stand that includes a movable target mount configured to support a target, with the target adjustment stand including one or more actuators for adjusting the position of the target mount. A computer system is used to determine an orientation of the vehicle relative to the target adjustment stand, with the position of the target mount being adjusted based on the determined orientation of the vehicle relative to the target adjustment stand. Upon properly orienting the target mount, and the target supported thereon, a calibration routine is performed whereby the sensor is calibrated using the target.

    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.

    摘要: A calibration fixture for use during a calibration procedure of a machine vision vehicle wheel alignment system. The calibration fixture consists of a pair of support legs, and a rotating transverse bar supported within an outer support tube secured between the support legs. The rotating transverse bar is supported within the outer support tube by a pair of annular bearings adjacent each end of the outer support tube, and is isolated from external influences which may result in deflection or distortion. A hub for receiving a sensor or optical target is secured to each end of the rotating transverse bar, such that optical targets mounted to each hub are maintained in axial alignment at opposite ends of the rotating transverse bar.

    摘要: A calibration frame for calibrating a reference system for vehicle measurement has setting elements, which enable a precise spatial orientation of the calibration frame, and multiple defined points of support, which are designed to accommodate a reference system carrier. In one specific embodiment, the points of support are designed in such a way that the reference system carrier is situatable on the points of support in at least two different orientations. In a second specific embodiment, a leveling element is provided which indicates the spatial orientation of the calibration frame in relation to the earth's gravitation field.

    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.
