20080255724 | Method for Detecting Road Lane Markings - A method for detecting road lane markings for a motor vehicle in motion with an image recording unit is presented. The image recording unit points to the road in front of the vehicle and in the recorded image data, brightness differences (contrasts) are analysed and/or edges are extracted. Road lane markings are detected by means of their periodic arrangement. For evaluation purposes, the measuring signal of the image recording unit is transformed into another coordinate system, and the auxiliary function thus obtained is tested for periodic structures. | 10-16-2008 |
20090296415 | Method for automatic full beam light control - A method for the automatic light control for a motor vehicle with a camera sensor for monitoring the environment in front of the motor vehicle is presented. With the camera sensor, an image sequence of the motor vehicle environment in front of the motor vehicle is recorded. The lane of the own motor vehicle is estimated from the image data. At least one evaluation window along the lane is set in the image, so that preceding and oncoming motor vehicles are recorded. Points of light in the image sequence are pursued (tracked). On the basis of the image data, the lights of other motor vehicles are detected, and the front headlights are controlled in such a manner that the drivers of other motor vehicles are not blinded. | 12-03-2009 |
20100007728 | System for Determining Objects - A system for multimodal detection of objects in a field of vision located in front of or behind a vehicle, wherein a surroundings-sensing process is carried out by a radar sensor, the radar sensor output signal is fed to a radar signal analysis method, and a visual surroundings-sensing process is carried out by a video sensor, the video output signal being fed to a video analysis method. Object determination takes place such that objects detected by the radar signal analysis method are fed for verification to an object confirmation and situation analysis module by an object detected by the video analysis method. | 01-14-2010 |
20100026806 | Detection and categorisation of points of light with a camera in a motor vehicle environment - A method for detecting and categorising points of light for a motor vehicle with a camera sensor directed towards the motor vehicle environment is presented. Here, at least one first category for passive, illumined reflectors and at least one second category for self-radiating, moving lights, in particular motor vehicle lights, is provided. For this purpose, the time progression of the intensity of a point of light is analysed. On the basis of the intensity fluctuation, points of light are categorised as motor vehicle lights or as reflectors. | 02-04-2010 |
20100061594 | DETECTION OF MOTOR VEHICLE LIGHTS WITH A CAMERA - A method for detecting front headlights and tail lights of a motor vehicle with a colour camera sensor is presented. The colour camera sensor comprises a plurality of red pixels, i.e. image points which are only sensitive in the red spectral range, and a plurality of pixels of other colours. In a first evaluation stage, only the intensity of the red pixels in the image is analysed in order to select relevant points of light in the image. | 03-11-2010 |
20110069303 | Method for Detecting Misalignment of a Vehicle Headlight Using a Camera - A method for detecting misalignment of a vehicle headlight using a camera system is specified. For this purpose, the headlight is in a predefined position and the camera system is arranged on or in the vehicle and is oriented in such a manner that the light distribution pattern of the headlight in front of the motor vehicle is detected. With a predefined headlight position, an actual light distribution pattern of the headlight is recorded using the camera system and is compared with a desired light distribution pattern for the predefined headlight position. If the actual light distribution pattern differs from the desired light distribution pattern, misalignment of the headlight is detected. | 03-24-2011 |

20140267628 | ESTIMATION OF COEFFICIENTS OF FRICTION USING A 3-D CAMERA - A method and a device for estimating the coefficient of friction by a 3D camera. The 3D camera records at least one image of the vehicle's surroundings. The image data of the 3D camera is used to produce a height profile of the road surface in the entire space ahead of the vehicle. Based on the height profile, the local coefficient of friction of the road surface that is to be expected in the space ahead of the vehicle is estimated. | 09-18-2014 |
20140320644 | DETERMINATION OF A HEIGHT PROFILE OF THE SURROUNDINGS OF A VEHICLE BY MEANS OF A 3D CAMERA - The invention relates to a method and a device for determining a height profile of the surroundings of a vehicle by means of a 3D camera. The 3D camera records at least one image of the vehicle's surroundings. The image data of the 3D camera is used to determine whether there is at least one jump in the height curve of the surface of the surroundings transversely to the direction of travel of the vehicle. | 10-30-2014 |
20140347448 | Determining the Characteristics of a Road Surface by Means of a 3D Camera - The invention relates to a method and a device for detecting the condition of a pavement surface by means of a 3D camera. | 11-27-2014 |
