    摘要: Apparatus is provided for determining the distance of a vehicle from a roadway side marking. An arrangement of light sensitive sensor elements is fitted to the vehicle for optically scanning a portion of the roadway located in front of the vehicle. An evaluation unit, connected downstream of the sensor element arrangement, is also provided. Only one or a few sensor element lines are used as the sensor element arrangement. Each line scans a narrow strip of the roadway which runs in front of the vehicle, not parallel to the vehicle longitudinal axis, and extends laterally as far as the roadway side marking. The evaluation unit reads each sensor element line sequentially and processes the received signals to determine the lateral distance of the vehicle from the roadway marking. The relatively small quantity of data which accumulates permits the processing of the data digitally in real time by a conventional microprocessor. The apparatus is used as sleep warning system or lane guard for motor vehicles.

    摘要: A camera based position recognition system for a road vehicle. The environment in the direction of travel of the vehicle is acquired by a camera. Using the acquired image data, the position of the vehicle in its environment is determined with regard to an optical signature identified in the obtained image data. For determining the position of the vehicle, use is made of the knowledge of the relationship between the environment coordinate system of the optical signature and that of the camera coordinate system. In simplified manner, position determination occurs with regard to the optical signature on the basis of a template matching imposed on the image data. For this, a template or an optical signature recorded in memory is superimposed on the optical signature identified in the image data in the environment of the vehicle (template matching). From the parameters of this template matching (for example linear compression and rotation parameters) recognizing the existing coordinate system, the position of the vehicle relative to the optical signature can be directly deduced.

    摘要: The first commercially-available driver assist systems required a compromise between the resolution of the scanning and the extent of the scanned region, according to application. Conventional video-based systems have a good compromise between resolution and recording range, however do not generally provide direct distance information. According to the new arrangement of the object of the invention, it is possible to achieve a system, which, on installation in a road vehicle, can record complex dynamic scenes, for example the lateral 3D geometry to the road edge from the point of view of the dynamically operating vehicle and use the same to advantage on parking. According to the invention, the monitoring and measuring of the lateral environment of a vehicle is displayed on the one hand by means of a camera with the digital images and on the other hand with a computer unit which serves to provide the images with a time stamp and to buffer the same. The movements of the vehicle are further recorded, in order to select image pairs from the buffered images, based on the above data. A local 3D depth image of the lateral environment of a vehicle can thus be generated by an algorithm for stereo image processing.

    摘要: In a method for detecting and tracking objects by stereo image evaluation a part of structure class images is initially generated from a recorded stereo image pair. Differences in brightness of selected pixels in the environment are determined for each pixel as digital values, which are combined to form a digital value group, with identical groups defining their own structure classes. Structure classes which lack a brightness change along the epipolar line are discarded. Corresponding disparity values are then determined for the pixels in the other structure classes and are collected in a disparity histogram with a given frequency increment. The pixel group that belongs to a given grouping point area of the histogram is then interpreted as an object to be detected.

    摘要: A method for environmental representation, in which two images of an environment (U) are taken respectively and a disparity image is determined by means of stereo image processing. An unobstructed free space (F) is identified in the disparity image, in that each pixel of the disparity image is allocated either to the unobstructed ground surface (B) or to one of several segments (S11 to Snu) depending on disparity values of the respective pixel. Segments (S11 to Snu) of the same width are formed from pixels of the same or similar distance to an image plane. An object (O1 to Ok) located outside of the free space (F) is modelled in the environment (U) using one segment (S11 to Snu) or several segments (S11 to Snu).
