  • Publication number: 20220019813
    Abstract: A device and a method that enable safe driving by performing object recognition using image analysis and inter-vehicle communication information are implemented. Provided are an image analysis unit that analyzes an image captured by a vehicle-mounted camera and performs object recognition in the image, an unknown object identification unit that identifies an unknown object in an image area determined to be an unknown object area as a result of analysis by the image analysis unit, and a communication unit that transmits information to an unknown object such as a second vehicle identified by the unknown object identification unit. The unknown object identification unit identifies the second vehicle, which is an unknown object in the image area determined to be the unknown object area, using the peripheral object information received through the communication unit. The communication unit transmits unknown object information or control information for travel control of the second vehicle to the second vehicle.

  • Patent number: 11216677
    Abstract: To improve estimation accuracy of a self-position. Light at a predetermined wavelength is projected. An image of a reflector with a reflectance higher than a predetermined reflectance is taken by receiving reflected light of the projected light reflected by the reflector. Own orientation is estimated on the basis of the taken image of the reflector. As a result, the self-position can be highly accurately estimated on the basis of the reflector even at night. The present disclosure can be applied to an on-board system.

  • Publication number: 20210350578
    Abstract: A comparison area detection unit of image processing circuitry detects an image area of a fading determination object on the basis of an image signal generated by an image capturing unit using a color filter as a comparison area. A color information generation unit generates color information from the image signal of the comparison area and uses the color information as comparison target information. A color information comparison unit compares the color information of the fading determination object as fading determination reference information with the comparison target information. A fading information generation unit generates fading information indicating that a fading level of the color filter exceeds a predetermined level or the fading level of the color filter on the basis of comparison information indicating a comparison result between the fading determination reference information and the comparison target information. The fading state of the color filter can be detected with precision.
