Publication number: 20210003419Abstract: A system for generating confidence values for objects in a digital road map comprising a backend and an object recognition device including: a capture unit, an evaluation unit, a positioning unit, and a transceiver. The capture unit captures surroundings data of a vehicle. The positioning unit determines a position of the captured surroundings data and objects contained therein. The evaluation unit recognizes the objects and concealed objects based on the surroundings data and associates them with position information. The transceiver transmits information generated by the evaluation unit to the backend. The backend generates or updates the map. Each of the objects in the map has an associated confidence value. The backend adjusts the confidence values based on the received data. The backend does not reduce the confidence value of an object if there is a corresponding concealed object in the received data.Type: ApplicationFiled: March 21, 2019Publication date: January 7, 2021Applicant: Continental Automotive GmbHInventors: Henning Hamer, Holger Karn

Patent number: 9928594Abstract: A method for automatic spatial calibration of a network of cameras along a road includes, processing a frame that is obtained from each camera of the network to automatically identify an image of a pattern of road markings that have a known spatial relationship to one another. The identified images are used to calculate a position of each camera relative to the pattern of road markings that is imaged by that camera. Geographical information is applied to calculate an absolute position of a field of view of each camera. A global optimization is applied to adjust the absolute position of the field of view of each camera of the camera network relative to an absolute position of the fields of view of other cameras of the camera network.Type: GrantFiled: July 7, 2015Date of Patent: March 27, 2018Assignee: AGT INTERNATIONAL GMBHInventors: Henning Hamer, Arsenii Sawchuk, Markus Schlattmann, Roel Heremans

Patent number: 9679200Abstract: In queues, persons—or objects (120) in general—move inside an area (110) to a target (112), such as to a counter. The queue has movement characteristics in terms of speed, waiting times and queue form. A computer-implemented approach obtains the characteristics by receiving a sequence (140) of image frames (141, 142, 143, 49) that represent the surveillance area (110); calculating flow vectors that indicate an optical displacement for the sequence (140) of image frames (141/142, 142/143); extending one of the flow vectors as lead vector in extension directions; determining intermediate vectors by using flow vectors along the extension directions; and selecting one the intermediate vectors as the new lead vector. The steps are repeated to concatenate the lead vectors to the movement characteristics (190).Type: GrantFiled: July 18, 2013Date of Patent: June 13, 2017Assignee: AGT INTERNATIONAL GMBHInventors: Markus Schlattmann, Henning Hamer, Ulf Blanke
