Abstract: A lighting device for vehicles with a number of light sources and with an optic unit to generate a predetermined light distribution, with the optic unit comprising at least one optic area, held via holding means in a predetermined assembly position, with a transparent substrate being provided with a plurality of grooves as fastening means so that an edge of the optic area can be framed in the groove.
Abstract: The invention relates to a method and device for determining object property of an object with the aid of images that have been recorded with the aid of a camera. Further, the invention relates to a method for determining a calibration parameter for a stereo camera. For determining the object property of an object, the object is defined in a first image recorded with the aid of the camera. Further, the brightness of a defined object is determined. Each time after a preset time interval, a further image is recorded with the aid of the camera. The object is defined in each of the further images and each time, the brightness of the defined object of each image is determined. Dependent on the brightness curve, an object property is assigned to the object.
Abstract: The present invention relates to a method for the optical self-diagnosis of a camera system and to a camera system for carrying out the method. The method comprises recording stereo images obtained from in each case at least two partial images (2, 3) creating a depth image, that is to say a disparity map (5) given by calculated disparity values, determining a number of valid disparity values (6) of the disparity map (5), and outputting a warning signal depending on the number of valid disparity values determined. A device for carrying out such a method comprises a stereo camera (1) having at least two lenses (7,8) and image sensors, an evaluation unit and a display unit.
Abstract: A circuit configuration for powering electrical loads, especially light emitting diodes, using a DC voltage converter with controllable switching element.
Abstract: A method for fixing an optical unit on a carrier, includes the steps of connecting the optical unit to the carrier with a substance-to-substance bond, and supporting the optical unit so that it can move relative to the carrier in a specified alignment direction by means of an alignment pin guided in an elongated hole before the substance-to-substance bonding of the optical unit to the carrier until the optical unit has reached a specified target position relative to the carrier where the substance-to-substance bond between the optical unit and the carrier is produced.
