A device for measuring the characteristic angles and dimensions of wheels, steering system and chassis of vehicles in general, comprising a plurality of three-dimensional optical readers which are functionally connected to a computer and can be arranged peripherally to a vehicle whose dimensions and characteristic angles of wheels, steering system and chassis are to be measured in such a manner that each one frames at least one wheel of the vehicle for the three-dimensional acquisition of an image of the wheel, each three-dimensional optical reader being provided with at least one fixed target for the setting and calibration of the measurement device, at least one camera of each three-dimensional optical reader being arranged in such a manner as to frame clearly and directly at least one fixed target of another three-dimensional optical reader for the setting and calibration of the measurement device by three-dimensional acquisitions of the fixed targets.
Method and apparatus for multi-axle vehicle alignment with vehicle frame reference
A vehicle wheel service system including a plurality of sensors positioned in proximity to a heavy-duty multi-axle vehicle, to measure angles associated with three or more axles of the vehicle without repositioning the mounting of the sensors after initiating a measurement procedure. Additional sensors, associated with a vehicle reference, such as the vehicle frame axis, are disposed to provide vehicle reference measurement data which is communicated to a processing system. The processing system is configured with software instructions to evaluate the measurement data and to determine various vehicle wheel alignment angle measurements and/or necessary vehicle adjustments for each axle relative to the vehicle reference or to a fixed axle having a determined relationship to the vehicle reference.
Vehicle alignment and sensor calibration system
A system and method for aligning a target to a vehicle for calibration of a sensor equipped on the vehicle includes multiple non-contact wheel alignment sensors configured for use in determining the orientation of tire and wheel assemblies of the vehicle. A target adjustment frame includes a target mount moveably mounted on a base frame, and includes multiple actuators configured to selectively move the target mount relative to the base frame, where the base frame is in a known orientation to the non-contact wheel alignment sensors. A computer system selectively actuates the actuators to position a target relative to the vehicle, with the target mount being moveable about a plurality of axes based on the determination of the orientation of the vehicle relative to the target adjustment frame to position the target relative to a sensor of the vehicle whereby the sensor is able to be calibrated using the target.
SYSTEM FOR SIMULTANEOUS MEASUREMENT OF WHEEL ALIGNMENT ANGLES AND WHEEL RUNOUT OF MULTI-AXLE VEHICLES
The present disclosure relates to the field of automobile engineering and provides a system for simultaneous measurement of “Wheel runout” and “Wheel alignment angles” of a multi-axle vehicle having a plurality of axles and wheels. The system includes a plurality of wheel targets, at least two camera modules, and an alignment control module. The plurality of wheel targets is respectively mounted on the axle wheels. Each of the camera modules has a camera that is configured to capture images of the plurality of wheel targets. The alignment control module has a processor co-operating with each of the camera module and configured to capture and analyze the images of the Targets to compute the “Runout”and “Wheel Alignment angles” of all the wheels of all the axles simultaneously. The processor is further configured to compare the analyzed wheel alignment angles with a predetermined range of acceptable wheel alignment angles.
SYSTEM AND METHOD FOR OPERATOR GUIDED IDENTIFICATION OF VEHICLE REFERENCE LOCATIONS FOR ADAS SENSOR ALIGNMENT
A vehicle service system incorporating a pair of gimbal-mounted optical projection systems enables an operator to selectively orient each optical emitter of the optical projection system to illuminate a location on a vehicle surface in proximity to the system. Signals indicative of an orientation of each optical emitter about three-axes of rotation are received at a controller programmed with software instructions to utilize the received signals, together with known locations for the systems, to calculate a three-dimensional coordinate for the illuminated location within an established frame of reference. The controller is further programmed to utilize the calculated three-dimensional coordinate of the illuminated location as an origin point for determining one or more placement locations within the established frame of reference for ADAS sensor calibration or alignment targets.
SYSTEM AND METHOD OF OPTICAL SCANNING OF A VEHICLE FOR MEASURING AND/OR CONTROLLING THE VEHICLE AND/OR PARTS THEREOF
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 METHOD AND A SYSTEM FOR DETERMINING WHEEL ALIGNMENT PARAMETER OF A VEHICLE
The present disclosure relates to a method determining wheel alignment parameter of a vehicle comprising a vehicle body. In particular, the method is performed by attaching a measuring arrangement to positions at a first and second longitudinally extending side portions of the vehicle body, respectively. A first and a second lateral center position are determined whereby a wheel alignment parameter in the form of a longitudinally extending centerline of the vehicle is determined.
VEHICLE WHEEL ALIGNMENT MEASUREMENT SYSTEM CAMERA AND ADAS CALIBRATION SUPPORT STRUCTURE
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.
DEVICE FOR CHASSIS MEASUREMENT AND METHOD FOR CHASSIS MEASUREMENT
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.
