Abstract
An occupant monitoring device includes processing circuitry configured to: acquire a captured image in which an inside of a vehicle is captured by an imaging device provided in a movable component in the vehicle; perform sensing that is at least one of state determination of an occupant or personal authentication of the occupant by image processing of the captured image; estimate whether or not there is a change in a position of the imaging device; perform calibration for the image processing; and not perform the sensing and perform the calibration when the-processing circuitry estimates that there is a change in the position of the imaging device.
Claims10
An occupant monitoring device comprising:
- processing circuitry configured to
- acquire a captured image in which an inside of a vehicle is captured by an imaging device provided in a movable component in the vehicle;
- perform sensing that is at least one of state determination of an occupant or personal authentication of the occupant by image processing of the captured image;
- estimate whether or not there is a change in a position of the imaging device;
- perform calibration for the image processing;
- and
- not perform the sensing and perform the calibration when the processing circuitry estimates that there is a change in the position of the imaging device, wherein
- when the processing circuitry estimates that the position of the imaging device does not change continuously for a preset time, the processing circuitry performs the calibration, and
- the preset time corresponds to a time necessary for a position or an angle of the movable component to be changed by an operation of the occupant or an instruction of the vehicle.
An occupant monitoring method comprising:
- acquiring a captured image in which an inside of a vehicle is captured by an imaging device provided in a movable component in the vehicle;
- performing sensing that is at least one of state determination of an occupant or personal authentication of the occupant by image processing of the captured image;
- estimating whether or not there is a change in a position of the imaging device;
- performing calibration for the image processing;
- and
- performing the calibration without performing the sensing when it is estimated that there is a change in the position of the imaging device, wherein
- the occupant monitoring method further comprises:
- when estimating that the position of the imaging device does not change continuously for a preset time, performing the calibration, and
- the preset time corresponds to a time necessary for a position or an angle of the movable component to be changed by an operation of the occupant or an instruction of the vehicle.
A non-transitory computer readable medium with an executable program stored thereon, wherein the program instructs a computer to perform:
- acquiring a captured image in which an inside of a vehicle is captured by an imaging device provided in a movable component in the vehicle;
- performing sensing that is at least one of state determination of an occupant or personal authentication of the occupant by image processing of the captured image;
- estimating whether or not there is a change in a position of the imaging device;
- performing calibration for the image processing;
- and
- performing the calibration without performing the sensing when it is estimated that there is a change in the position of the imaging device, wherein
- the program instructs the computer to further perform:
- when estimating that the position of the imaging device does not change continuously for a preset time, performing the calibration, and
- the preset time corresponds to a time necessary for a position or an angle of the movable component to be changed by an operation of the occupant or an instruction of the vehicle.
