  • Patent number: 11514683
    Abstract: An on-board outside recognition apparatus extracts a feature point from an image including an environment around a user's own vehicle, measures a three-dimensional position of the feature point based on movement of the feature point tracked in time series on the image and calculates a foot position of the feature point on the image from the three-dimensional position of the feature point is performed. Then, the on-board outside recognition apparatus extracts a road surface area where the user's own vehicle can travel, from the image using a degree of similarity of a texture of the image, and judges a feature point the foot position of which is judged not to be included in the road surface area to be highly reliable.

  • Patent number: 11318930
    Abstract: A parking assistance device includes: a marking line detector that detects a plurality of marking lines delineating a parking area from an image taken by an imaging unit; a second determiner that determines whether or not the type of parking for parking a vehicle in a parkable area is angle parking, on the basis of the angle obtained between a parking baseline joining the endpoints on the vehicle side of the detected plurality of marking lines and the plurality of marking lines, or the angle obtained between the parking baseline and one marking line selected from among the plurality of marking lines; and a parking position setter that, in the case where the second determiner determines that the type of parking corresponds to angle parking, sets a parking position inside the parkable area in which to park the vehicle, on the basis of the parking baseline.
