  • Publication number: 20110044557
    Abstract: A method for rectifying a camera image includes: receiving a plurality of distorted pixels of a distorted camera image; receiving a compressed rectifying rule, via an interface; and performing a decompression of the compressed rectifying rule, in order to obtain a decompressed rectifying rule for rectifying the distorted camera image. A plurality of rectified pixels of a distorted camera image is determined from the plurality of distorted pixels, using the decompressed rectifying rule.

  • Publication number: 20100303336
    Abstract: 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.

  • Publication number: 20100060885
    Abstract: 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.

  • Publication number: 20090309026
    Abstract: An optical unit, having a sensor device in particular, including a housing enclosing same, a radiation-sensitive sensor surface, designed for detecting electromagnetic radiation from a frequency section, having a predefined width and position, of the spectral range including the near infrared range and/or the visible range, and a lens system. In order to reduce the cost and complexity for mounting a lens on the housing and to obtain a uniform housing surface on the object side, a part of the lens system acting as a lens on the object side or the entire lens system of the unit is designed as an integral component of the housing of the unit.

  • Publication number: 20090312966
    Abstract: A method for checking a vibration damper of a motor vehicle in the installed state includes setting start values of the damping constant kA, the spring rate cA, and the body mass mA for a wheel of a motor vehicle; inducing a vertical vibration of the motor vehicle with the aid of a defined excitation sRreal; determining the theoretical body vibration excursion sAmodel; optically detecting the positions of the wheel and the body shell of the motor vehicle at a plurality of detection instants during the vibration; minimizing the error function formed from the deviations between the theoretical body vibration excursion sAmodel and the observed body vibration excursion sAreal at the detection instants, and determining the damping constant kA, the spring rate cA, and the body mass mA therefrom; and determining the damping measure ? of the vibration damper.
