    摘要: A method for determining at least one threshold value S for distinguishing, in the dark, between reflectors and vehicle lights that are recorded as light spots by a camera sensor oriented towards the surroundings of a vehicle. The camera sensor records a series of images of the surroundings of the vehicle. At least one light spot in the series of images is tracked. When the tracking of a light spot is completed, at least one parameter (for example the maximum intensity Imax of the light spot in the entire series of images, or the lifetime τ of the light spot) is determined from measured values, for example from the intensity of the light spot in each image. The threshold value S is then adapted to the determined parameter/s. The determined parameter value of the light spot is included in a frequency distribution of the parameter values from previously tracked light spots. A new threshold value for distinguishing between vehicle lights and reflectors is determined from the updated frequency distribution of the parameter values. After temporal filtering a new threshold value for distinguishing between reflectors and vehicle lights is fixed.

    摘要: 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.

    摘要: A method and a device for distinguishing between reflectors arranged on the roadside and vehicle lights and for identifying said reflectors and vehicle lights for use in an automatic light control system in a vehicle with a camera sensor oriented towards the surroundings of the vehicle. The method includes recording a sequence of images of the surroundings of the vehicle. Light spots are found and subjected to temporal tracking within the sequence of images. Afterwards, for each light spot, a decision is made whether the light source of the light spot is a vehicle light or a reflector. A statistical map for the entire camera image is determined from the position of the light spots found with the statistical map comprising regions that are predominantly occupied by reflectors and regions that are predominantly occupied by vehicles driving ahead or by oncoming vehicles. All light sources that are found within the regions occupied by reflectors are identified as potential reflectors and all light sources within the regions occupied by vehicle lights are identified as potential vehicle lights.

    摘要: 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.

    摘要: Image data of optically acquired input images (1) are processed for emphasizing at least two object classes. Each pixel is subjected to a rough classification (10) based on first criteria that determine whether or not a pixel is relevant for an object recognition. A reduced image (11) is formed from the relevant pixels and irrelevant pixels are omitted. The reduced image (11) is filtered (20) for forming at least two correlated filtered images (21, 22, 23) based on second criteria. Classified images (31A, 32A, 33A) are formed from the filtered images by classifiers that work in accordance with predetermined rules. Weighting factors are allocated to each object class. The classified images are merged in accordance with an algorithm to make a combined global evaluation for each object class. The global evaluation decides, based on the merged images (41A, 41B, 41C), for each pixel whether the respective pixel belongs to an object class and if so to which object class.
