20100165102 | METHOD AND DEVICE FOR DETERMINING A CHANGE IN THE PITCH ANGLE OF A CAMERA OF A VEHICLE - A method and device determine the change in pitch angle of a camera of a vehicle. At least three images, each reproducing a detection area in front of the vehicle, are sequentially recorded and corresponding image data are generated. A position of a first reproduction of a stationary object in the first image is determined as a first image position. A position of a second reproduction of the stationary object in the second image is determined as a second image position. On the basis of at least the first image position and the second image position, the course of a straight line is determined. A position of a third reproduction of the stationary object in the third image is determined as a third image position. On the basis of the distance between the third image position and the straight line, the change in the pitch angle is determined. | 07-01-2010 |
20130021451 | METHOD AND DEVICE FOR DETERMINING A CALIBRATION PARAMETER OF A STEREO CAMERA - 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. | 01-24-2013 |
20130229521 | METHOD AND DEVICE FOR RECOGNISING PULSING LIGHT SOURCES - The invention relates to a method and a device for recognising a pulsing light source, in which a sequence of individual images is acquired with a light sensitive sensor. In an evaluation unit, all or at least some of the picture points of each individual image are examined with regard to at least one predefined feature. A gray value of any picture point depends on two or more charge levels of at least one of the photodetectors of the sensor corresponding to the picture point at the ends of at least two integration intervals for the picture point. The at least two integration intervals for said picture point have different lengths. The examination comprises an examination of the picture points as to whether the picture points have gray values in a defined vicinity of one of at least one predefined gray value. | 09-05-2013 |
20130286670 | METHOD AND A DEVICE FOR TESTING A LIGHTING DRIVING ASSISTANCE SYSTEM - The invention relates to a method and an apparatus for checking a lighting driving assistance system of vehicles. In this case, a vehicle is positioned in front of a body and a light of the vehicle is aimed at this body. Brightness distributions are obtained by adjusting the light in the horizontal and vertical directions in a plurality of angular positions and are recorded by an image capture unit. The recorded brightness distributions are used to calculate the distance and angular offset as well as the position of the body and actual values of the angular positions. These actual values are compared with preset desired values, and recommended settings for minimizing a difference between desired and actual values are output. | 10-31-2013 |
20140217888 | METHOD FOR CALIBRATING AT LEAST ONE HEADLAMP - The invention relates to a method for calibrating at least one headlamp ( | 08-07-2014 |
20150085506 | METHOD FOR CONTROLLING THE ILLUMINATION OF A ROAD PROFILE - The invention relates to a method for controlling illumination of a road profile, wherein the headlamp at least one light-emitting element, wherein the at least one light-emitting element is individually drivable in order to generate an individual luminous flux, wherein the light emitted by the at least one light-emitting element has a light distribution, wherein the lateral adaptation of the light distribution is performed depending on a determined road profile, in particular as a function of the distance from the headlamp. | 03-26-2015 |
20150085507 | METHOD FOR CONTROLLING A LIGHT DISTRIBUTION OF A HEADLAMP AND HEADLAMP THEREFOR - The invention relates to a method for controlling a light distribution of a headlamp, wherein the headlamp has at least one light-emitting element, wherein the at least one light-emitting element is individually drivable in order to generate an individual luminous flux, wherein the light emitted by the at least one light-emitting element has a light distribution, wherein the light distribution is defined by means of a predefined, three-dimensional basic distribution on the basis of parameters, wherein an adapted light distribution is varied on the basis of the basic distribution using selected, changed parameters. | 03-26-2015 |

20150063635 | METHOD AND APPARATUS FOR EVALUATING RESULTS OF GAZE DETECTION - The invention relates to a method and an apparatus for evaluating results of gaze detection, wherein these results are present or are obtained in the form of information which defines, for each of a multiplicity of successive times, a viewing direction detected at this time and a focal point identified thereby in a scene image assigned to this time. For this purpose, the invention provides for the following steps to be carried out: —a temporal change in the viewing direction and/or the focal point is evaluated in order to identify different viewing events which differ from one another by different speeds of an eye movement, wherein saccades and fixations and/or pursuit movements are detected as different types of viewing events and the identified viewing events are classified according to the type thereof, —a period of time spanned by the times is divided into intervals in such a manner that an interval corresponding to a duration of the particular viewing event is assigned to each of the identified viewing events, wherein at least some of these intervals each contain a sequence of a plurality of times, —precisely one of the times or a true subset of the times is selected in each case from each of the intervals assigned to a fixation or a pursuit movement, —and, for each of these selected times, the focal point identified in the scene image assigned to the particular time is mapped to a position corresponding to this focal point in a reference image. | 03-05-2015 |
