  • Patent number: 11062158
    Abstract: Accurate driver state determination achieving safety is enabled without being affected by differences between individual drivers. A driver state determination apparatus for determining a driver state, such as distracted driving, includes a calculator that determines a direction of a vehicle driver's face or gaze based on first sensing data output from a first sensor and including an image of the driver, and calculates statistical information about a direction in which the driver looking straight ahead retains his or her gaze with respect to a forward direction of a vehicle. A correction unit corrects the determined face or gaze direction of the driver with respect to a reference direction defined as the forward direction of the vehicle based on the statistical information. A determiner determines a driver state based on a deviation of the corrected face or gaze direction of the driver from the reference direction.

  • Patent number: 10776944
    Abstract: A face position detecting device includes: an image analyzer configured to analyze an image of a face imaged by an imaging unit and to extract a positional relationship between at least two characteristic points in the face; and a face position calculator configured to calculate a position of the face. The face position calculator calculates a position of the face in a space, upon operation of an operation screen, according to positional relationships among the face imaged, the imaging unit, and an operation unit, and except upon the operation, according to the positional relationship between the at least two characteristic points that the image analyzer extracts from the face imaged and positional relationships between a plurality of positions of the face and a plurality of the at least two characteristic points corresponding to the plurality of positions of the face obtained in respective operations, respectively.

  • Patent number: 10467489
    Abstract: A driver performing a lane check by looking back for safe driving can be alerted based on the driver's gaze deviating from a view area for usual driving. A distracted driving determination apparatus, a distracted driving determination method, and a program for distracted driving determination recorded on a recording medium compare a change pattern detected from changes in the gaze or face orientation of the driver with a predetermined reference pattern, and change a usual determination condition for detecting distracted driving to a temporary determination condition when the change pattern matches the reference pattern. This prevents the line check from being determined to be distracted driving.

  • Publication number: 20190279365
    Abstract: An imaging apparatus accurately detects an obstacle interfering with image capturing as distinguishable from an obstacle not interfering with image capturing. An image captured by an imaging unit is divided into a plurality of sections, and the captured image is divided into a plurality of blocks each including a predetermined number of sections. For each of the blocks, an obstructed state of each section in each of the blocks is checked. When the obstructed state of each section in at least one block interferes with image capturing of the subject (when at least a part of the central area is obstructed), an obstacle between the imaging unit and the subject is detected.

  • Publication number: 20190266743
    Abstract: An occupant monitoring apparatus for measuring the spatial position of an occupant predetermined site with a camera includes a camera capturing an image of a vehicle occupant, an image processor processing the captured image, and a position calculator calculating the spatial position of the occupant predetermined site using the processed image. The camera is installed on a steering wheel of the vehicle away from a rotational shaft to be rotatable together with the steering wheel. The image processor rotates two images captured at two positions by the camera rotated together with the steering wheel to generate rotated images. The position calculator calculates the spatial position of the occupant predetermined site using a linear distance between the two positions, a parallax obtained from the rotated images, and a focal length of the camera.
