    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: 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).

    摘要: A method for detecting objects, wherein two images of a surrounding (1) are taken and a disparity image is determined by means of stereo image processing, wherein a depth map of the surrounding (1) is determined from the determined disparities, wherein a free space delimiting line (2) is identified, delimiting an unobstructed region of the surrounding (1), wherein outside and along the free space delimiting line (1) the depth card is segmented by segments (3) of a suitable width formed by pixels of the same or similar distance to an image plane, wherein a height of each segment (3) is estimated as part of an object (4.1 to 4.6) located outside of the unobstructed region in a way, such that each segment (3) is characterized by the two-dimensional position of the base (for example the distance and angle to the longitudinal axis of the vehicle) and the height thereof.

    摘要: The invention relates to a method for detecting objects on a pixel plane. Said movable object detection is frequently possible only by tracking the pre-segmented objects or the parts thereof. in this relation, the spatially adjacent objects often provoke problems, in particular in the case when a camera system or more precisely an observer is movable. The inventive method consists in determining a two-dimensional position of the relevant pixels inside a first image and in determining an associated remote value for each relevant pixel. Said pixels are tracked and localized on two ore more successive images, wherein the two-dimensional position or the pixel offset and the associated remote value are again determined for each pixel. The position and movement of the relevant pixels are also determined with the aid of a suitable filter. Finally, the relevant pixels are combined into objects under predefined conditions with respect to the position, moving direction and motion ratio thereof.

    摘要: A device for acquiring data indicative of the path of a lane is provided. The device incorporates a lane detection sensing circuit, an object position sensing circuit that detects at least the distance of an object located in front of the vehicle and its directional angle relative to the direction of vehicle motion, and a sensing circuit for the vehicle's own motion. An estimating device is provided that is supplied with lane recognition measurement data, object position measurement data, and measurement data on the vehicle's own motion. As a function of the vehicle's own motion, the estimating device determines the lane curvature and/or the transverse position of an object ahead of the vehicle relative to the lane by estimation, using a presettable estimation algorithm including a dynamic vehicle motion model. The device preferably includes a Kalman filter for this purpose, and is used, for example, in road vehicles.
