An optical scanning system for measuring and/or controlling a vehicle and/or parts of a vehicle, wherein the vehicle is arranged on a support surface. The optical scanning system comprises two optical reader apparatuses, which are arranged on said support surface, on opposite sides of the vehicle, and are provided with respective optical image capturing devices configured to provide respective data/signals encoding one or more images of the vehicle, an electronic system, which is designed to process the data/signals in order to construct one or more three-dimensional images of the vehicle. The optical image reader apparatuses each comprise a calibration target, which lies on an approximately horizontal support surface and is arranged immediately adjacent to the optical image capturing device of the relative optical image reader apparatus at a predetermined distance from it.

A sensor calibration tool, in particular for calibrating sensors on a vehicle, includes a vertical rail defining a first axis, and first and second carriage assemblies. The first carriage assembly is supported by the vertical rail, movable along the first axis, and has a horizontal rail defining a second axis transverse to the first axis. The second carriage assembly is supported by the horizontal rail, movable along the second, and has a target mount that releasably supports a calibration target. A calibration tool includes a horizontal rail defining a first axis, a first carriage assembly movable along the first axis, a mounting bar defining a second axis and pivotable about a pivot axis transverse to the first and second axes, and a target mount positioned on the mounting bar. The first carriage assembly and the mounting bar move independently.

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.

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 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 simulation hub includes an end plate, a clamping portion and a measuring disc, in which the clamping portion and the measuring disc are both detachably fixed to the end plate; the clamping portion includes a first positioning hole for positioning and clamping, the first positioning hole is a cylindrical hole, and the cylindricity of the first positioning hole is smaller than a preset value; the outer circumference of the measuring disc includes at least a measuring cylindrical surface having a preset axial length and a bus parallel to an axis of the first positioning hole, and circular runout test values of the measuring cylindrical surface are preset first or second harmonic runout values; and the outer diameter of the measuring cylindrical surface is adapted to the inner diameter of the first positioning hole.

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.

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.

Vehicle alignment systems and methods are disclosed which operate based on a calculation of “drive direction,” or the direction in which a vehicle is moving. Since a vehicle can be assumed to be a rigid body, each wheel has the same drive direction. Consequently, an alignment parameter of one wheel can be compared to the same parameter of another wheel by equating their drive direction, eliminating the need for the aligner to “see” both sides of the vehicle at the same time. Embodiments include a system having one or more cameras on a fixture carrying a calibration element for an ADAS system, and one or more targets placed on the vehicle to measure the drive direction of the vehicle. The drive direction is assumed to be parallel to the vehicle thrust line and can be used as the line for orientation of the fixture to the vehicle.
