Publication number: 20220082407Abstract: A map system includes a vehicle apparatus that is mounted to a vehicle. The map system includes an imaging apparatus, a server, and an integrating unit. The imaging apparatus captures an image of a surrounding area of the vehicle. The server generates a map using data that corresponds to feature points extracted from the image captured by the imaging apparatus that is transmitted from the vehicle apparatus. The integrating unit weights the pieces of data that are transmitted from a plurality of vehicle apparatuses based on bias in the pieces of data and generates a map by integrating at least a portion of the plurality of pieces of data based on the weighting.Type: ApplicationFiled: November 24, 2021Publication date: March 17, 2022Inventors: Kentarou SHIOTA, Naoki NITANDA, Kazuma ISHIGAKI, Shinya TAGUCHI

Publication number: 20220044031Abstract: The travelling route recognition unit recognizes, based on an image captured by an imaging apparatus capturing an area in the vicinity of the vehicle, a travelling route where the vehicle travels. The classifying unit classifies the travelling route into at least one of a predetermined plurality of road models. The edge point extracting unit extracts edge points necessary for expressing the road model classified by the classifying unit among edge points indicating a boundary of the travelling route recognized by the travelling route recognition unit. The parameter generation unit correlates road model information indicating the road model classified by the classifying unit with the edge points extracted by the edge point extracting unit and generates a travelling route parameter indicating the travelling route recognized by the travelling route recognition unit. The transmission unit transmits the travelling route parameter generated by the parameter generation unit to the server.Type: ApplicationFiled: October 21, 2021Publication date: February 10, 2022Inventors: Kentarou SHIOTA, Naoki NITANDA, Kazuma ISHIGAKI, Shinya TAGUCHI

Patent number: 9493108Abstract: An on-vehicle apparatus detects other vehicle lights from an image picked up outside the vehicle. The apparatus acquires an image around the vehicle and extracts light sources from the image. The apparatus calculates a target area probability that is a probability of a light source in a target area being different vehicle light, in accordance with a probability that light-source feature quantities at least including either of a color of light source and a shape of light source coincide with target-area feature quantities, the target area indicating a preset site that is a part of an area indicating each of the light sources. The target-area feature quantities are prepared as feature quantities of vehicle light, being correlated to the position of a target area. The apparatus outputs information that a light source having the target area probability of not less than a preset threshold is different vehicle light.Type: GrantFiled: September 19, 2012Date of Patent: November 15, 2016Assignee: DENSO CORPORATIONInventors: Taiji Morishita, Hironori Sato, Kentarou Shiota

Patent number: 9469242Abstract: In a headlamp light distribution control device, a light source configured by a pair of lamps mounted in a forward vehicle is extracted from an image of the forward vehicle if a distance to the forward vehicle is less than a predetermined value, and the number of the extracted light sources is judged. When the number of the extracted light sources is two, an irradiation direction of a headlamp is controlled such that a shielded area is set in an irradiation area to prevent an area including the lamp of the forward vehicle from being irradiated. When the number of the extracted light sources is one, the irradiation direction is controlled such that a shielded area is set in the irradiation area to have a margin in right and left directions larger than the shielded area set when the number of the extracted light sources is two.Type: GrantFiled: October 13, 2014Date of Patent: October 18, 2016Assignee: DENSO CORPORATIONInventors: Koji Imaeda, Kentarou Shiota

IMAGING APPARATUS WHICH SUPPRESSES FIXED PATTERN NOISE GENERATED BY AN IMAGE SENSOR OF THE APPARATUS
Publication number: 20130335601Abstract: An imaging apparatus detects and registers fixed-noise pixels as those pixels of the image sensor which produce fixed pattern noise, and includes an optical element which disperses light that is incident on the image sensor. The detection is performed by identifying isolated high-luminance pixels within captured images and, for each isolated high-luminance pixel, evaluating the luminance values of peripherally adjacent pixels. A judgement is made as to whether an isolated high-luminance pixel is a fixed-noise pixel based upon comparing luminance values of the peripherally adjacent pixels with a predetermined threshold value, the judgement preferably being performed only while images are captured during hours of darkness.Type: ApplicationFiled: June 13, 2013Publication date: December 19, 2013Inventors: Kentarou SHIOTA, Toshikazu MURAO, Takayuki KIMURA -
