Abstract: A method corrects errors in position-measuring devices having material measures which are scanned by at least one scanning unit. Correction values are obtained in a calibration performed prior to a measurement operation. The correction values from the calibration are compressed for the measurement operation. The correction values are kept available for a defined number of correction points on the material measure and used during the measurement operation to correct acquired position values.

Abstract: A method and a device for determining the orientation of at least one rail of a measuring station of a chassis measuring device or a motor vehicle test line. The device has at least one sensing device, the at least one sensing device has at least one camera and at least one illumination unit. The at least one illumination unit illuminates at least one section of the rail using structured or unstructured light and the at least one camera records the light reflected by the rail.

Abstract: Automatic illuminating and image recording system for an automobile service device, combined illuminating and image recording unit and method for automatic measured value-dependent setting of the image recording and exposure for an automobile service device having contactless measuring capability. Comprises at least one camera (32, 34) having an interface to a control unit, at least one illuminating unit (62, 64) having a control input, and a control unit. This control unit is equipped with an interface to the camera(s) (32, 34), with an interface to the illuminating unit(s) (62, 64), with an image processing-and, respectively, image pre-processing-unit and with an evaluating unit that generates control parameters for the illuminating unit(s) (62, 64) and/or the camera(s) (32, 34).

Abstract: A method for the relative positioning of an object to be measured with respect to a measuring device, first of all the object to be measured is detected by the measuring device and the position of the object to be measured with respect to the measuring device is ascertained. Then a return message signal is generated which indicates whether the object to be measured is located in a position that is suitable for taking the measurement or not.
