Device control apparatus
A device control apparatus includes an imaging unit configured to capture an image of an occupant in a vehicle, a first recognition unit configured to recognize a posture of the occupant based on the image captured by the imaging unit, a second recognition unit configured to recognize a state of a hand including at least a shape of the hand of the occupant based on the image captured by the imaging unit, a discrimination processing unit configured to specify a device to be controlled and an operation to be executed based on the posture of the occupant recognized by the first recognition unit and the state of the hand recognized by the second recognition unit, and a controller configured to issue a control command corresponding to the specified device to be controlled and the specified operation to be executed.
1. A device control apparatus for controlling a device mounted in a vehicle, the device control apparatus comprising:
a camera configured to capture an image of an occupant in the vehicle; and
at least one processor programed to
recognize a posture of the occupant based on the image captured by the camera;
recognize a shape of a hand of the occupant based on the image captured by the camera;
specify a device to be controlled and an operation to be executed based on a combination of the recognized posture of the occupant and the recognized shape of the hand; and
issue a control command corresponding to the specified device to be controlled and the specified operation to be executed.
2. The device control apparatus according to claim 1 , wherein the at least one processor is configured to specify the device to be controlled and the operation to be executed, by referring to discrimination processing information in which information indicating the posture of the occupant, information indicating the shape of the hand, information indicating the device, and information indicating the operation are associated in advance.
3. The device control apparatus according to claim 2 , wherein:
in the discrimination processing information, a skeleton pattern represented by a skeleton coordinate sequence is defined as the information indicating the posture of the occupant, and the shape of the hand is defined as the information indicating the shape of the hand;
the at least one processor is configured to recognize a skeleton coordinate sequence of the occupant from the image captured by the camera; and
the at least one processor is configured to specify the device and the operation associated with the recognized posture of the occupant and the recognized shape of the hand as the device to be controlled and the operation to be executed, based on a degree of matching between (i) the recognized skeleton coordinate sequence of the occupant and the discrimination processing information and (ii) the recognized shape of the hand and the discrimination processing information.
4. The device control apparatus according to claim 2 , wherein:
in the discrimination processing information, a maintenance time of the posture of the occupant and the shape of the hand is further defined in association with each combination of the information indicating the posture of the occupant and the information indicating the shape of the hand;
the at least one processor is configured to also determine whether the recognized posture of the occupant and the recognized shape of the hand have continued for the maintenance time defined in the discrimination processing information or more, when the at least one processor specifies the device to be controlled and the operation to be executed based on a degree of matching between (i) the recognized posture and the discrimination processing information and (ii) the recognized shape of the hand and the discrimination processing information; and
the at least one processor is configured to issue the control command in response to specifying the device to be controlled and the operation to be executed, and determining that the recognized posture of the occupant and the recognized shape of the hand have continued for the maintenance time defined in the discrimination processing information, or more.
5. The device control apparatus according to claim 1 , wherein the at least one processor is further programed to estimate a state of the vehicle, and
the at least one processor is configured to decide whether to permit the specified operation based on the state of the vehicle estimated by the vehicle state estimation unit; and
the at least one processor is configured to issue the control command in response to specifying the device to be controlled and the operation to be executed and deciding that the specified operation is permitted.
6. The device control apparatus according to claim 1 , wherein the at least one processor is configured to issue an auxiliary command for interrupting or changing an operation instructed by the control command in response to a predetermined condition being satisfied after the control command has been issued.
