  • Patent number: 11151729
    Abstract: Improvement in the accuracy of estimating the position of a mobile entity even while traveling or if there is an error in the calibration performed utilizing: a mobile entity; an imaging device provided in the mobile entity; and an information processing device for determining a first movement amount by which a detection point that is the same object has moved on the basis of a first image and a second image acquired by the imaging device and a second movement amount by which the mobile entity has moved while the first image and the second image were acquired, determining the accuracy of recognizing the detection point acquired by the imaging device on the basis of the first movement amount and the second movement amount, and estimating the position of the mobile entity on the basis of the accuracy of recognition and position information that pertains to the detection point.

  • Patent number: 11132813
    Abstract: A distance to an object is estimated with a monocular camera that estimates a distance from a moving object to feature points on an image from an imaging device mounted on the moving object. The distance estimator sets one or more feature points on the image acquired from the imaging device at a first timing and detects the feature point on the image acquired from the imaging device at a second timing. The distance estimator also determines the movement amount of the feature point on the image between the first timing and the second timing and determines the movement amount of the moving object between the first and second timings. The distance estimator then estimates the distance from the moving object to the feature point based on the movement amount on the image and the movement amount of the moving object between the first and second timings.

  • Patent number: 10650252
    Abstract: The reliability of detection of the traveling lane can be improved even in a case where an image capturing environment changes. The lane detection device includes a first image capturing device which is fixed to a moving body and periodically captures a first image under a predetermined first image capturing condition, a second image capturing device which is fixed to the moving body and periodically captures a second image under a second image capturing condition different from the predetermined first image capturing condition, and an operation device, regarding a traveling lane on which the moving body travels, which detects a first boundary line of the traveling lane on the first image, detects a second boundary line of the traveling lane on the second image, and estimates the position of the first boundary line on the first image based on a position of the second boundary line on the second image under a predetermined execution condition.

  • Patent number: 10509971
    Abstract: Landmark recognition can handle various landmarks with a low processing load and high reliability. Provided are a database, a segmentation processor, a pattern extraction processor, and a database comparison processor. The database stores landmark extraction information associated with landmark determination condition information, the landmark extraction information identifying a region including a landmark of an image, and allowing right-opposite positioning of the landmark, the landmark determination condition information used for determining landmark pattern information as the landmark. The segmentation processor sets a plurality of segmentation lines with respect to the region including the landmark of the image in a direction parallel to the landmark from a direction right opposite to the landmark, and determines a distance between intersections of the segmentation lines and a boundary of the landmark.
