  • Patent number: 11475713
    Abstract: In an apparatus for estimating a behavior of a vehicle carrying the apparatus based on images of surroundings of the vehicle captured by an imaging device, an information acquirer acquires beforehand specific location information that is information representing a specific location in which a situation around the vehicle is such that the estimation of the own vehicle behavior based on the images is unstable. In the apparatus, a behavior estimator estimates the own vehicle behavior based on the images captured by the imaging device and the specific location information.

  • Publication number: 20220082407
    Abstract: 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.

  • Publication number: 20220044031
    Abstract: 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.

  • Publication number: 20200158850
    Abstract: In an apparatus for learning a scale factor used to calculate a true value of a speed of a vehicle from a detected speed that is a sensor reading from a vehicle speed sensor, a sensor reading acquirer acquires the detected speed of the vehicle from the vehicle speed sensor. A relative speed detector detects a relative speed of the vehicle to a stationary object based on a result of detection by an object detector that detects an object around the vehicle. A scale factor calculator calculates the scale factor based on the relative speed and the detected speed.

  • Publication number: 20120307062
    Abstract: There is provided a vehicle-mounted image processing device that is capable of making a plurality of processing units appropriately perform processes corresponding to scenes in which there are many types, such as people, vehicles, etc., and in which they are combined. Based on processing results of image processing by a plurality of processing units 40, the vehicle-mounted image processing device generates tag information representing the type and priority of image processing to be executed next by each of the processing units 40, and, using tag information generated during previous image processing, determines whether or not to have each of the processing units 40 perform image processing.
