A support structure having a vertical element supporting a set of cameras associated with a vehicle measurement or inspection system together with at least one target structure required for realignment or recalibration of onboard vehicle safety system sensors. A camera crossbeam carried by the support structure locates the set of cameras as required to view a vehicle undergoing measurement or inspection. The target structure is affixed to the vertical element of the support structure, at an elevation suitable for observation by at least one vehicle onboard sensors during a realignment or recalibration procedure. A set of rollers facilitates positioning of the target structure on a supporting floor surface during a realignment or recalibration procedure.

An apparatus for chassis measurement for determining the alignment of the wheels of a motor vehicle. The apparatus includes a detachably fixed measurement head apparatus on the vehicle wheel to be measured, wherein the measurement markings are positioned parallel to the front and rear side of the vehicle or the vehicle stand level. After arranging the fastening apparatus and positioning the measurement markings, the laser light source is activated and a plane is projected in space, wherein the length of these laser light lines generates at least intersection points together with the measurement markings, the intersection points of which are detected as track gauge and used for computation in order to determine the fall, trailing and spread data and the virtual longitudinal travel axis of the vehicle. By a camera-assisted measurement value detection apparatus, different electromagnetic spectra for each wheel to be measured are detected and supplied for data processing.

A set-up tool for aiding vehicle sensor calibrations having a structure with a first and second vehicle contact points configured to contact a vehicle and establish a calibration axis. A substantially vertically projected flat blade laser may be placed in a position perpendicular to the calibration axis and used to align the set-up tool with a center of the vehicle. Once centered, the laser ma be transitioned to project a laser line, in coordination with a protractor having a base-line parallel to the calibration axis (which is now substantially parallel to a transverse axis of the vehicle), at a discreet angle away from the center of the vehicle. A target may then be placed along the laser line to aid in the calibration of vehicle sensors.

A system and method of calibrating an ADAS sensor of a vehicle by aligning a target with the sensor using a target adjustment stand that includes a base frame and 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. The position of the target mount is adjusted based on the 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.

The optical axis adjustment system 3 adjusts an optical axis O of a radar device R in a vehicle V in which the radar device R that detects an external environment is attached to a vehicle body B, and includes an adjustment target T that is movable in an inspection chamber Rb in which the vehicle body B is disposed, a radar attachment position and direction calculation unit that calculates an attachment position of the radar device R and a direction of the optical axis, a normal posture calculation unit that calculates a normal posture of the adjustment target T on the basis of a calculation result of the radar attachment position and direction calculation unit, and a target movement unit that sets a posture of the adjustment target T to a normal posture.

An apparatus (1) for measuring an alignment of a wheeled vehicle (V), comprises: two contact tracks (P) for the wheels of the vehicle, extending along a longitudinal direction (L); a measuring assembly (2), including a measuring unit (21), for capturing one or more images of the vehicle and generating corresponding image data, and a connector (22), having a first end (22A) connected to the measuring unit (21) and positioned at a first height (Q1), and a second end (226), positioned at a second height (Q2), greater than the first height (Q1); a control unit (3), configured to receive the image data (301) from the measuring unit (21) and to process the image data (301) to derive vehicle alignment information therefrom. The measuring unit (21) is movable towards and away from the contact tracks (P).

The disclosure provides a method and auxiliary target for aligning a calibration device to a vehicle. The calibration device includes a calibration bracket and a calibration laser emitter. The calibration bracket includes a crossbar. The method includes: placing a vehicle on a horizontal plane; setting a calibration center point; turning on the calibration laser emitter, so that the calibration laser emitter emits two fan-shaped beams, the two fan-shaped beams forming, on the horizontal plane, a first laser line and a second laser line that intersect and are perpendicular to each other; and adjusting a position of the crossbar, so that a point of intersection of the first laser line and the second laser line coincides with the calibration center point and the first laser line coincides with the line of intersection of the central axial plane of the vehicle and the horizontal plane.

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.

Methods and systems measure a vehicle body parameter; e.g., a wheel alignment parameter such as ride height. Embodiments include a system having a target attachable to a vehicle body, and an image sensor for viewing the target and capturing image data thereof. A processor processes the image data, determines an initial spatial position of the target based on the processed image data, compares the initial spatial position of the target with a reference position, and prompts a user to align the target to an adjusted spatial position when the initial spatial position differs from the reference position more than a threshold amount. The vehicle body parameter value is determined based on the target's adjusted spatial position. In certain embodiments, the adjusted spatial position differs from the reference position by a position error value, and the processor mathematically corrects the vehicle body parameter value based on the position error value.
