Patent number: 7737832Abstract: An assistance system for motor vehicles has at least one monitoring unit monitoring a space external to a vehicle, in particular in a direction of travel of the motor vehicle, with a warning zone being defined in the monitored external space on each side of a lane. The warning zone is delimited by an earliest warning line and a latest warning line encompassing the respective lane marking or, as the case may be, boundary. An evaluation unit receives the data transmitted by the monitoring unit and generates a warning signal for an acoustic, visual and/or haptic warning and/or a steering intervention if the evaluation unit detects that a defined warning threshold lying within the warning zone is exceeded. The warning signal is issued only as a function of further planned driver-adaptive conditions.Type: GrantFiled: May 13, 2005Date of Patent: June 15, 2010Assignee: Siemens AktiengesellschaftInventors: Gregory Baratoff, Ludwig Ertl, Thorsten Köhler, Martin Pellkofer, Andre Rieder

Patent number: 7508979Abstract: A system and method for detecting an occupant and head pose using stereo detectors is disclosed. In the training stage, pairs of images taken simultaneously from a pair of stereo cameras are received and components in each pair of images are identified. Features are associated with each component and a value is associated with each feature. Among them, a subset of features with best discriminative capabilities is selected and forms a strong classifier for a given component in a pair of images. In the detection stage, the strong classifiers are used in the incoming image pairs to detect components. Identified components are used to detect occupants and head pose of the occupants. Stereo detection is combined with stereo matching in a systematic way to improve occupant detection and localization.Type: GrantFiled: November 18, 2004Date of Patent: March 24, 2009Assignee: Siemens Corporate Research, Inc.Inventors: Dorin Comaniciu, Thorsten Köhler, Binglong Xie, Ying Zhu

Patent number: 7466841Abstract: A method for detecting and recognizing at least one traffic sign is disclosed. A video sequence having a plurality of image frames is received. One or more filters are used to measure features in at least one image frame indicative of an object of interest. The measured features are combined and aggregated into a score indicating possible presence of an object. The scores are fused over multiple image frames for a robust detection. If a score indicates possible presence of an object in an area of the image frame, the area is aligned with a model. A determination is then made as to whether the area indicates a traffic sign. If the area indicates a traffic sign, the area is classified into a particular type of traffic sign. The present invention is also directed to training a system to detect and recognize traffic signs.Type: GrantFiled: April 19, 2005Date of Patent: December 16, 2008Assignee: Siemens Corporate Research, Inc.Inventors: Claus Bahlmann, Ying Zhu, Visvanathan Ramesh, Martin Pellkofer, Thorsten Köhler

Patent number: 7227626Abstract: The invention relates to a method for determining the current position (A, B, C, D) of a head (9) of an occupant (8) in the passenger compartment (2) of a motor vehicle (1), said head moving toward an automatic dynamic disabling zone (6) in front of an airbag module (5). To this end, the invention makes use of the idea that the best position for a measurement with regard thereto is the point in space where the ideal direction of movement (14) of the head (9) is perpendicular to an ideal line of sight (17) of the camera (160. The measurement is then preferably carried out when the geometric center (10) of the head (9) crosses this point. In a preferred embodiment, the calculation of the actual movement vector of the head (9) is taken as a basis, said head being preferably perpendicular in a current line of sight (18) of the camera (16). The invention advantageously increases the potential for protecting an occupant (8) in a motor vehicle (1).Type: GrantFiled: April 1, 2004Date of Patent: June 5, 2007Assignee: Siemens AktiengesellschaftInventors: Ludwig Ertl, Thorsten Köhler
