A device for checking the wheel suspension of a vehicle, in particular, of a motor vehicle, includes: a device for determining the wheel normals and/or the center of rotation of a wheel of the vehicle; a device for determining the movement trajectory of the wheel normals and/or of the center of rotation of the wheel during a movement of the vehicle; and a comparison and evaluation device, which is configured to compare the determined movement trajectory of the wheel normals and/or of the center of rotation of the wheel to a predefined movement trajectory, and to output a defect message when the deviation of the determined movement trajectory from the predefined movement trajectory exceeds a predefined limiting value.
摘要:
A vehicle position detection and guidance system for use with an automotive service lift having a pair of runways onto which a vehicle is driven in order to be elevated. The system consists of a LiDAR sensor disposed to provide a field of view encompassing a volume of space extending upward from the upper surface of each lift runway, as well as the intervening region between the runways. The LiDAR sensor to observes at least the leading tread surfaces of two or more wheels on a vehicle approaching the service lift, and a volume of space below the vehicle. Output from the LiDAR sensor is conveyed to a processing system, which monitors the wheel positions relative to the runway surfaces, and provides output indicating steering corrections, obstructions, and a vehicle stopping point as the vehicle is driven onto the runways and/or the lift elevation changes.

A wheel alignment system includes a side-to-side reference including an active reference pod and a passive reference pod disposed on opposite sides of the vehicle. The active reference pod includes a reference image sensor fixedly attached to a reference target, for mounting on a first side of the vehicle such that the reference image sensor produces image data including a perspective representation of the passive reference pod disposed on a second/opposite side of the vehicle. In operation, alignment cameras on the opposite sides of the vehicle capture perspective representations of targets mounted to vehicle wheels and of targets of the active and passive reference pods. A computer processes the image data to compute an alignment measurement of the vehicle based on a spatial relationship between the active reference pod and the passive reference pod determined according to the image data produced by the reference image sensor.

A method for testing a vehicle underbody of a motor vehicle includes: recording at least one image of at least one region of the vehicle underbody of the motor vehicle using a camera device; producing a three-dimensional depth image with the aid of the at least one recorded image of the at least one region of the vehicle underbody of the motor vehicle; and testing the at least one region of the vehicle underbody of the motor vehicle with the aid of the produced three-dimensional depth image of the vehicle underbody using optical image recognition.
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:
A process for calibrating and evaluating a machine-vision vehicle wheel alignment system having front and rear imaging components associated with each of the left and right sides of a vehicle support structure. Each pair of imaging components defines a front and rear field of view, with a common overlapping region associated with each respective side of the vehicle support structure. Optical targets disposed within each of the overlapping field of view regions are observed by the imaging components to establish performance ratings for the system as a whole, for groups of components within the system, and for individual components within the system.
摘要:
A vehicle wheel alignment system has a plurality of cameras, each camera for viewing a respective target disposed at a respective wheel of the vehicle and capturing image data of the target as the wheel and target are continuously rotated a number of degrees of rotation without a pause. The image data is used to calculate a minimum number of poses of the target of at least one pose for every five degrees of rotation as the wheel and target are continuously rotated the number of degrees of rotation without a pause. At least one of the cameras comprises a data processor for performing the steps of preprocessing the image data, and calculating an alignment parameter for the vehicle based on the preprocessed image data.

摘要:
An image-recording device for aligning vehicles has at least one camera; at least one illumination device; and at least one color-selective beam splitter that is designed to channel light from different directions into the at least one camera and/or to color-selectively direct light from the at least one illumination device into different directions. The color-selective beam splitter has at least one optical marker that is able to be captured by a camera of another image-recording device, in order to determine the position of the color-selective beam splitter in relation to the camera of the other image-recording device.
