Abstract
Official abstract text for this publication.
An acquisition unit acquires vehicle information and a moving image frame as image information captured by an imaging unit from a database. An extraction unit extracts a captured image in which at least one of a direction of a face of an occupant and a position of a gaze point satisfies a predetermined inattentive driving condition from among captured image in which a vehicle speed is equal to or higher than a predetermined threshold value and a steering angle is within a predetermined range.
First claim
Opening claim text (preview).
What is claimed is: 1. An information processing device comprising: a processor configured to execute instructions for: acquiring a captured image of a moving image of a face of an occupant, and steering angle information indicating a steering angle of a vehicle and vehicle information indicating a vehicle speed, the steering angle information and the vehicle information corresponding to the captured image; and extracting a captured image in which at least one of a direction of the face of the occupant and a position of a gaze point satisfies a predetermined inattentive driving condition, from among the captured images in which the vehicle speed is equal to or higher than a predetermined threshold value and the steering angle is in a predetermined range, wherein: the extracting extracts a captured image in which the inattentive driving condition continues for a predetermined time or longer and less than a predetermined abnormal time; the extracting excludes a captured image in which the inattentive driving condition continues for the predetermined abnormal time or longer; and the extracting extracts at least one of a captured image in which an absolute value of the direction of the face is maximum and a captured image in which a distance from a front region to the gaze point is maximum from among the captured images in which the inattentive driving condition is satisfied. 2. The information processing device according to claim 1 , wherein the processor is further configured to preferentially extract a captured image in which the absolute value of the direction of the face is maximum when both the direction of the face and the position of the gaze point satisfy the inattentive driving condition. 3. An information processing system comprising: a vehicle including a sensor that captures an image of a face of an occupant and that generates a captured image of a moving image; and a processor configured to execute instructions for: acquiring the captured image of the moving image of the face of the occupant, and steering angle information indicating a steering angle of the vehicle and vehicle information indicating a vehicle speed, the steering angle information and the vehicle information corresponding to the captured image, and extracting a captured image in which at least one of a direction of the face of the occupant and a position of a gaze point satisfies a predetermined inattentive driving condition, from among the captured images in which the vehicle speed is equal to or higher than a predetermined threshold value and the steering angle is in a predetermined range, wherein: the extracting extracts a captured image in which the inattentive driving condition continues for a predetermined time or longer and less than a predetermined abnormal time; the extracting excludes a captured image in which the inattentive driving condition continues for the predetermined abnormal time or longer; and the extracting extracts at least one of a captured image in which an absolute value of the direction of the face is maximum and a captured image in which a distance from a front region to the gaze point is maximum from among the captured images in which the inattentive driving condition is satisfied. 4. An information processing method in which a computer executes processes comprising: acquiring a captured image of a moving image of a face of an occupant, and steering angle information indicating a steering angle of a vehicle and vehicle information indicating a vehicle speed, the steering angle information and the vehicle information corresponding to the captured image; and extracting a captured image in which at least one of a direction of the face of the occupant and a position of a gaze point satisfies a predetermined inattentive driving condition, from among the captured images in which the vehicle speed is equal to or higher than a predetermined threshold value and the steering angle is in a predetermined range, wherein: the extracting extracts a captured image in which the inattentive driving condition continues for a predetermined time or longer and less than a predetermined abnormal time; the extracting excludes a captured image in which the inattentive driving condition continues for the predetermined abnormal time or longer; and the extracting extracts at least one of a captured image in which an absolute value of the direction of the face is maximum and a captured image in which a distance from a front region to the gaze point is maximum from among the captured images in which the inattentive driving condition is satisfied.
