  • Patent number: 11900669
    Abstract: A calibration device performs a calibration between a plurality of imaging devices, each of which outputs field-of-view information which is information on a field-of-view of the imaging device itself. The field-of-view information contains a bitmap image and a range image. The calibration device includes: a state estimation part configured to detect, in a field of view of a first imaging device, an image of a second imaging device, and estimate a relative position and a relative attitude of the second imaging device with respect to the first imaging device, based on the detected image; and a transformation information calculation part configured to calculate transformation information between a coordinate system of the first imaging device and a coordinate system of the second imaging device, based on the estimated relative position and relative attitude.

  • Publication number: 20230249618
    Abstract: A luminance determining unit determines a luminance distribution of an exterior circumstantial image in a line-of-sight direction of a driver, and a luminance changing unit determines a bright region of this luminance distribution. Further, the luminance changing unit determines a luminance after the change in a peripheral region of this bright region. A virtual-image creating unit creates a virtual image based on the determined luminance, and a display processing unit displays this virtual image on a display unit. In this manner, since a display system displays the virtual image for use in increasing the luminance in periphery of the bright region, the feeling of the brightness for the driver can be moderated, and therefore, the visual recognition can be improved. That is, the display system can output the virtual image depending on the circumstances.

    Abstract: A luminance determining unit 14 determines a luminance distribution of an exterior circumstantial image in a line-of-sight direction of a driver 300, and a luminance changing unit 15 determines a bright region 301 of this luminance distribution. Further, the luminance changing unit 15 determines a luminance after the change in a peripheral region 302 of this bright region 301. A virtual-image creating unit 16A creates a virtual image based on the determined luminance, and a display processing unit 17 displays this virtual image on a display unit 200. In this manner, since a display system 1A displays the virtual image for use in increasing the luminance in periphery of the bright region 301, the feeling of the brightness for the driver 300 can be moderated, and therefore, the visual recognition can be improved. That is, the display system 1A can output the virtual image depending on the circumstances.

  • Patent number: 11405600
    Abstract: A first mirror has a first reflecting surface convexed in a first direction, a first apex, and a first fan shape. A second mirror has a second reflecting surface convexed in a second direction, a second apex, and a second fan shape. An imaging optical system forms images from a first light emitted from an object, reflected by the first reflecting surface, and subsequently further reflected by the second reflecting surface, and a second light emitted from the object and reflected by the second reflecting surface. The first and second fan shapes have interior angles of 180° or more. A center position of the image sensor is displaced with respect to an optical axis of the imaging optical system. A short side of a photo-receiving surface of the image sensor and a center line of the image of the first or second fan shape are approximately parallel.

  • Patent number: 10992920
    Abstract: The purpose of the present invention is to provide a stereo image processing device that is capable of expanding the effective field of view by using a lens having distortion for realizing a wide field of view. This stereo image processing device has two sensors arranged so as to be shifted from the optical axes of respective lenses in directions separating each other, wherein each of the lenses has a property such that the distortion, in a region of a large viewing angle, is greater than that of an f? lens.
