摘要： A device for wheel alignment measurement comprises at least two sensors which are configured to record each time at least two images of the front wheels and the rear wheels of a vehicle passing by; and an evaluation device which is configured to evaluate the images recorded by the sensors in order to determine whether the vehicle has traveled along a straight line. The sensors are arranged such that a vehicle to be measured can pass between the at least two sensors. The evaluation device is configured to determine the geometric travel axis of the vehicle and/or the individual tracks of the wheels on the front axle and/or the rear axle of the vehicle when the evaluation of the images recorded by the sensors reveals that the vehicle has traveled along a straight line.

摘要： 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.

摘要： A method for ascertaining the axis of rotation of a vehicle wheel in which a light pattern is projected at least onto the wheel during the rotation of the wheel and the light pattern reflected from the wheel is detected by a calibrated imaging sensor system and analyzed in an analyzer device. Accurate and robust measurement of the axis of rotation and, optionally, of the axis and wheel geometry, in particular when the vehicle is passing by, is achieved in that a 3D point cloud with respect to the wheel is determined in the analysis and a parametric surface model of the wheel is adapted thereto; normal vectors of the wheel are calculated for different rotational positions of the wheel for obtaining the axes of rotation; and the axis of rotation vector is calculated as the axis of rotation from the spatial movement of the normal vector of the wheel.

摘要： The invention relates to a method for determining the wheel geometry and/or axle geometry of motor vehicles by means of an optical measuring apparatus. According to said method, at least two recording points are assigned to each other and are referenced in relation to the measuring space with the aid of an image recording system, optionally taking into account reference characteristics and vehicle body characteristics, an object segment (6) comprising the wheel (5) that is to be measured is detected from different perspectives, and the position of wheel characteristics in the measuring space is evaluated during the measurement. In order to create an advantageous procedure regarding the operation and the accuracy of the measurement, a plurality of individual 3D pixels representing the three-dimensional surface of the object segment that is detected by the at least two image recording devices (2) are determined from the object segment using image processing methods by correlating images, and the wheel characteristics and/or reference characteristics and/or vehicle body characteristics are obtained therefrom.

摘要： The invention relates to a method for optically measuring an undercarriage and/or for dynamically testing undercarriage components of a motor vehicle (1). At least one wheel (2) and/or at least one section of the vehicle (1) is illuminated with a light pattern (15) of structured light by means of an illumination device (11), and the reflected light (4′) is received by means of an imaging sensor unit (12, 13) and evaluated in an evaluation unit (16). The invention also relates to a device for carrying out the method. Even in suboptimal light conditions in the surrounding environments, a robust measurement is achieved because the structured light is emitted by the illumination device in a narrow band in a specified narrow emission wavelength range, and because the light is likewise detected by means of the sensor unit (12, 13) in a receiving wavelength range corresponding to the emission wavelength range and is evaluated in the evaluation unit (16), wherein foreign light influences are removed.

摘要： Apparatus and methods are provided for measuring vehicle wheel alignment characteristics. According to one embodiment, during a first measurement cycle, spatial coordinates of multiple points on the wheel are obtained by positioning a vision sensor at various angular offsets relative to the wheel, the multiple points representative of samples from each of the various angular offsets. After the first measurement cycle and before the second measurement cycle, the wheel is rotated at least a partial revolution. During the second measurement cycle, spatial coordinates of multiple points on the wheel are obtained by positioning the vision sensor at various angular offsets relative to the wheel, the multiple points representative of samples from each of the various angular offsets. Finally, one or more characteristics of the wheel are determined based upon the spatial coordinates collected during the first measurement cycle and the spatial coordinates collected during the second measurement cycle.
