Patent number: 9160986Abstract: A device for monitoring surroundings of a vehicle mounted in a vehicle, captures an image of surroundings of the vehicle, extracts from the captured image an image area for a predetermined part of a desired type of object, and sets a predetermined area below the extracted image area. The device extracts candidates for the desired type of object present outside the vehicle based on the predetermined area and determines, for each of the extracted object candidates, whether the object candidate is the desired type of object. When no pattern different from the background is captured in the predetermined area, or when a pattern different from the background is captured only in one of a first and a second areas, then the object in the image area is excluded from the candidates for the desired type of object. Thus, a pedestrian, for example, can be distinguished from an artificial structure.Type: GrantFiled: November 9, 2011Date of Patent: October 13, 2015Assignee: Honda Motor Co., Ltd.Inventors: Nobuharu Nagaoka, Makoto Aimura

Patent number: 8965056Abstract: When it is determined that a type of a physical body in real space corresponding to an image portion is a crossing pedestrian, a distance calculating unit 13 performs a first distance calculating process of calculating a distance between a vehicle 1 and the physical body, on the basis of a correlative relationship between the distance from the vehicle 1 set on assumption of a height of the pedestrian and a height of the image portion, according to the height of the image portion. When it is determined that the type of the physical body is not the crossing pedestrian, then the distance calculating unit 13 performs a second distance calculating process which calculates the distance between the physical body and the vehicle, on the basis of a change in size of the image portions of the physical body extracted from time-series captured images.Type: GrantFiled: June 22, 2011Date of Patent: February 24, 2015Assignee: Honda Motor Co., Ltd.Inventors: Kodai Matsuda, Nobuharu Nagaoka, Makoto Aimura

Patent number: 8953840Abstract: An imaging means mounted on a vehicle performs imaging resulting in grayscale images having brightness values corresponding to object temperature, and objects around the vehicle are detected from said images. On the basis of said grayscale images, display images to be displayed on a display device mounted on the vehicle are generated and displayed on the display device. The display images are generated by lowering the brightness of areas not corresponding to the objects detected in the grayscale images. The display device is positioned in the vehicle width direction at no more than a prescribed distance away from an imaginary line passing through the center of rotation of the vehicle steering wheel and extending in the longitudinal direction of the vehicle. Accordingly, because display images are generated in which only the objects are spotlighted, the driver can quickly comprehend the objects present when using a display device.Type: GrantFiled: February 21, 2011Date of Patent: February 10, 2015Assignee: Honda Motor Co., Ltd.Inventors: Nobuharu Nagaoka, Hideki Hashimoto, Makoto Aimura

Publication number: 20150035962Abstract: Provided is a vehicle periphery monitor device for accurately distinguishing between and detecting two side-by-side pedestrians and a vehicle that is lighting lights. With regard to a pedestrian candidate having at least two head candidates, a reference image creation unit creates the peripheral image of one of the head candidates as a reference image and creates an inverted image in which the right and left sides of the reference image are inverted. An object determination unit sets the peripheral image of the other heat candidate as a comparative image, and determines whether the head candidates are the pedestrians or the vehicle on the basis of the consistency of the reference image and the inverted image relative to the comparative image.Type: ApplicationFiled: January 10, 2013Publication date: February 5, 2015Applicant: HONDA MOTOR CO., LTD.Inventors: Nobuharu Nagaoka, Makoto Aimura
