Patent number: 10262215Abstract: A scene understanding device obtains map data where one, two or more obstacle detection frames, shaped corresponding to a road structure, for detecting an obstacle are set in advance for a specific spot on a road where a vehicle would otherwise bump into a vehicle or a pedestrian. The scene understanding device determines whether there exists an obstacle in the obstacle detection frames set for the specific spot on a scheduled traveling route of a host vehicle, and calculates the degree of risk at the specific spot based on a result of determining whether there exists an obstacle therein.Type: GrantFiled: April 23, 2015Date of Patent: April 16, 2019Assignee: Nissan Motor Co., Ltd.Inventors: Masanori Yoshihira, Seigo Watanabe, Norimasa Kishi

Patent number: 9649980Abstract: Captured images obtained beforehand by imaging ranges corresponding to peripheries of a vehicle, or processed images generated to correspond to the captured images are stored to be associated with stored road information of a preset area. A superimposed area having a clarity lower than a preset clarity threshold is set in a captured image of a periphery of the vehicle. A superimposition image is extracted among the stored images, the superimposition image being an image of a range corresponding to the captured image. A superimposed image is generated by superimposing an image in an area in the extracted superimposition image corresponding to the superimposed area on the captured mage. A video generated from the superimposed image is displayed at a position visible from a driver.Type: GrantFiled: April 5, 2013Date of Patent: May 16, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Seigo Watanabe, Norimasa Kishi, Takura Yanagi, Yoshiro Takamatsu

Patent number: 9046364Abstract: Based on an image imaged by an imaging unit (2), feature points of a plurality of objects present around a vehicle are detected by a feature point detecting unit (35). A first distance from the feature point to the imaging unit (2) is calculated based on a temporal change of the feature point. A second distance from a certain object included in the plurality of objects present in the image to the imaging unit is calculated using some pixels of the certain object. The first distance of the plurality of feature points, other than the certain feature point, simultaneously detected by the feature point detecting unit (35) is modified based on a ratio of the first distance and the second distance.Type: GrantFiled: April 24, 2012Date of Patent: June 2, 2015Assignee: NISSAN MOTOR CO., LTD.Inventors: Naoki Kojo, Seigo Watanabe, Toshiyuki Andou

Patent number: 7813530Abstract: A motion detection apparatuses and method where a characteristic region is extracted from an image produced by an imaging device are described. A modified region is formed by modifying the characteristic region. Voting occurs so as to count up to increase a count value at a memory address corresponding to a location inside the modified region and to reset a count value at a memory address corresponding to a location outside the modified region. At least one of the moving direction and the moving speed of the modified region is calculated based on a difference among accumulated count values for adjacent locations. The position of the modified region can be calculated based on count values and locations in the modified region.Type: GrantFiled: March 21, 2007Date of Patent: October 12, 2010Assignee: Nissan Motor Co., Ltd.Inventor: Seigo Watanabe
