  • Publication number: 20230021721
    Abstract: An image processing device 10 includes an image interface 18, a memory 19, and a controller 20. The image interface 18 acquires a captured image. The positions of specific feature points in a world coordinate system and reference positions of the specific feature points are stored in the memory 19. The controller 20 detects the specific feature points in the captured image. In a case where discrepancy between the position in the captured image and the reference position is found with regard to a predetermined percentage or more of the specific feature points, the controller 20 recalculates a calibration parameter.

  • Patent number: 10752166
    Abstract: A determination unit determines whether a driving behavior of a vehicle is performed by automatic driving control or manual driving control. A generation unit generates presentation instructing information for presenting the driving behavior by the automatic driving control externally from the vehicle when the determination unit determines that the driving behavior of the vehicle is performed by the automatic driving control, and generates presentation instructing information for presenting the driving behavior by the manual driving control externally from the vehicle when the determination unit determines that the driving behavior of the vehicle is performed by the manual driving control. An output unit outputs presentation instructing information generated by the generation unit.

  • Patent number: 10706301
    Abstract: A detection device includes an image segmenter and a detector. The image segmenter cuts out a first region image and a second region image from an image of a vehicle interior that is acquired from an imaging device. The first region image shows at least a portion of a first part of a body of an occupant. The second region image shows at least a portion of a region of the vehicle interior around the first part or at least a portion of a second part of the body of the occupant. The detector detects an orientation of the first part of the body of the occupant based on a feature amount of the first region image and a feature amount of the second region image.

  • Patent number: 10528044
    Abstract: A driver performs switching to a manual driving mode in a state that the driver is suitable for a driving operation. In a vehicle that is driven by a plurality of driving modes including a self-driving mode to be performed by a self-driving control unit and a manual driving mode in which a driver performs a part of or all of a driving operation, before the manual driving mode is started, information for presenting a request for operating by the driver from a user interface unit to the driver is output to the user interface unit. The input unit receives a signal based on the operation by the driver. A notification unit notifies a self-driving control unit of a switching signal for instructing switching to the manual driving mode when a difference between a value obtained from the signal based on the operation by the driver, the signal having been input from the input unit and a reference value according to the operation request is within an allowable range.

  • Patent number: 10417511
    Abstract: An image processor includes an image converter. The image converter transforms data of an image that is photographed with a camera for photographing a seat, based on a transformation parameter that is calculated in accordance with a camera-position at which the camera is disposed. The image converter outputs the thus-transformed data of the image. The transformation parameter is a parameter for transforming the data of the image such that an appearance of the seat depicted in the image is approximated to a predetermined appearance of the seat.
