Mobile unit control device and mobile unit
A mobile unit control device includes an imaging unit, an identification unit, and a control unit. When installed on a mobile unit, the imaging unit captures at least a portion of the surroundings of the mobile unit to obtain an image thereof. When the image captured by the imaging unit includes a figure of a person, the identification unit determines a trunk of the person in the figure of the person as a representative point. The control unit controls a movement of the mobile unit on the basis of the position of the representative point determined by the identification unit in the image.
1. A mobile unit control device comprising:
an imaging unit that, when installed on a mobile unit, captures at least a portion of surroundings of the mobile unit to obtain an image thereof;
an identification unit that, when the image captured by the imaging unit includes a figure of a person, determines a trunk of the person in the figure of the person as a representative point; and
a control unit that controls a movement of the mobile unit on a basis of a position of the representative point determined by the identification unit in the image; wherein
the control unit outputs a control to move the mobile unit backwards when the identification unit does not determine the representative point in the image captured by the imaging unit.
2. The mobile unit control device according to claim 1 , wherein
the identification unit extracts the representative point from each of a plurality of images captured by the imaging unit in sequence; and
the control unit controls the movement of the mobile unit on a basis of a change over time in the position of the representative point extracted by the identification unit.
3. The mobile unit control device according to claim 1 , wherein
the movement includes a moving direction of the mobile unit; and
the control unit changes an orientation of the mobile unit when the identification unit is unable to determine the representative point.
4. The mobile unit control device according to claim 1 , wherein, if the identification unit determines that the image captured by the imaging unit includes a figure of a person in a predetermined posture, the control unit starts controlling the movement of the mobile unit on the basis of the representative point of this person.
5. The mobile unit control device according to claim 4 , wherein the control unit outputs a notification to urge any person to assume the predetermined posture when the identification unit is unable to determine the representative point.
6. The mobile unit control device according to claim 1 , wherein the control unit controls the movement of the mobile unit so that a distance between the representative point and a reference point of the mobile unit will be equal to a predetermined distance.
7. A mobile unit, comprising:
a mobile unit control device, including:
an imaging unit that, when installed on a mobile unit, captures at least a portion of surroundings of the mobile unit to obtain an image thereof;
an identification unit that, when the image captured by the imaging unit includes a figure of a person, determines a trunk of the person in the figure of the person as a representative point; and
a control unit that controls a movement of the mobile unit on a basis of a position of the representative point determined by the identification unit in the image;
wherein
the mobile unit is structured to move in an arbitrary direction along a ground; and
the control unit outputs a control to move the mobile unit backwards when the identification unit does not determine the representative point in the image captured by the imaging unit.
8. The mobile unit according to claim 7 , the mobile unit being an automated guided vehicle.
