摘要： A method for determining distances for chassis measurement of a vehicle having a body and at least one wheel includes determining a center of rotation of a wheel of the vehicle by projecting a structured light pattern at least onto the wheel, recording a light pattern reflected by the wheel using a calibrated imaging sensor system, determining a 3D point cloud from the reflected light pattern, and determining the center of rotation of the wheel from the 3D point cloud. The method also includes determining a point on the body by evaluating the previously determined 3D point cloud or by evaluating a plurality of grey-scale images recorded under unstructured illumination. A height level is determined as a vertical distance between the center of rotation of the wheel and the point on the body.

摘要： A method for determining the tumbling motion of a vehicle wheel and/or a measurement object attached to the vehicle wheel in the context of an axle measurement. The tumbling motion is executed relative to the precise wheel axis of rotation of the vehicle wheel and at least one orientation value is determined between, the precise wheel axis of rotation and a reference axis. Using at least one image recording unit, at least two wheel features that are present on the vehicle wheel or are attached for the measurement are acquired as the vehicle travels past and are evaluated by an evaluation device situated downstream. Using the wheel features recorded as the vehicle travels past, a wheel coordinate system and a feature coordinate system are determined. The wheel coordinate system and the feature coordinate system are set into relation to one another in order to determine the orientation value.

摘要： A method for processing image data of two sensors of a stereo sensor system that are suitable for recording images, each of the sensors being configured to record the image data section by section in sensor sections of the sensor that are situated at different positions. The method includes providing information on a geometrical offset between the positions of two sensor sections of the first sensor and the second sensor which have corresponding image data, and reading out image information of the first sensor and image information of the second sensor, the reading out taking place with reference to the positions of the sensor sections, from which the image data are read out, using the offset.
