  • Publication number: 20210295563
    Abstract: A recognition processing section performs subject recognition in a processing area of an image obtained by an imaging section. The recognition processing section determines an image characteristic of the processing area on the basis of a characteristic map indicating an image characteristic of the image obtained by the imaging section and uses a recognizer corresponding to the image characteristic of the processing area. The characteristic map includes a map based on an optical characteristic of an imaging lens used in the imaging section and is stored in a characteristic information storage section. An imaging lens has a winder angle of view in all directions or in a predetermined direction than a standard lens, and the optical characteristic thereof differs depending on a position on the lens. The recognition processing section performs the subject recognition using a recognizer corresponding to resolution or skewness of the processing area, for example.

  • Publication number: 20210209379
    Abstract: The present technique relates to an information processing apparatus, an information processing method, a program, and a mobile body which enable accuracy of detection processing related to a passage around a mobile body to be improved. The information processing apparatus includes: a transforming unit configured to respectively transform a plurality of photographed images with partially overlapping photographing ranges into bird's eye images; a compositing unit configured to generate a composite image by compositing a plurality of the bird's eye images; and a detecting unit configured to perform detection processing related to a passage around a mobile body based on the composite image. For example, the present technique can be applied to an apparatus that detects a lane marking of a road.

  • Publication number: 20210065387
    Abstract: The present disclosure relates to a signal processing apparatus and a signal processing method, a program, and a moving body that allow improvement of estimation accuracy for a self-position. One of a plurality of wavelengths of light is selected, and the light with the selected wavelength is projected. Reflected light of the projected light is received that is reflected from a reflector corresponding to an object having a reflectance higher than a predetermined reflectance, and the reflector is detected. This prevents interference of light projected by another vehicle, enabling appropriate detection of the reflector and improvement of estimation accuracy for a self-position. The present disclosure is applicable to an in-vehicle system.

  • Publication number: 20210064893
    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: 20210042554
    Abstract: To provide a configuration that enables recognition of an unknown object included in an image. The configuration includes a network creation unit that creates a network linking a scene node indicating a scene type of an image and a node corresponding to an object, and an unknown object inference unit that compares a created network created by the network creation unit with a large number of reference networks created by learning processing, selects reference networks similar to the created network, selects, from the selected reference networks, a node corresponding to a node of an unknown object in the created network, and infers that an object associated with the selected node is an object corresponding to the unknown object.
