Abstract

A warning sign placing apparatus and a control method thereof are provided. The warning sign placing apparatus includes at least two camera units, a control unit, and a vehicle. The camera unit captures a plurality of images in a preset direction. The vehicle carries at least two camera units and control unit. The control unit identifies a traveling direction of the road and distinguishes at least one object on the road based on the images, and plans a route along the road for the vehicle according to the at least one object, where the vehicle travels along the route. A warning sign is configured in the warning sign placing apparatus and is able to automatically move to a preset position with a preset distance in order to avoid the risk of dangers in a case of manually placing the warning sign.

First claim

What is claimed is:

1 . A warning sign placing apparatus comprising:
at least two camera units, capturing a plurality of images in a preset direction; a control unit, coupled to the at least two camera units; and a vehicle, carrying the at least two camera units and the control unit,
wherein the control unit identifies a traveling direction of a road based on the images, distinguishes at least one object on the road, and plans a route along the road for the vehicle according to the at least one object, wherein the vehicle travels along the route.

2 . The warning sign placing apparatus according to claim 1 further comprising:
a storage unit, coupled to the control unit and storing the route; and
a receiving unit, coupled to the control unit and receiving a recall signal, wherein the recall signal is used to instruct the control unit for controlling the vehicle to return back along the route.

3 . The warning sign placing apparatus according to claim 1 , wherein the control unit distinguishes that the at least one object comprises a curb line, and wherein the control unit calculates an angle between the curb line and a preset imaginary line and controls a traveling direction of the vehicle according to the angle.

4 . The warning sign placing apparatus according to claim 1 , wherein the control unit distinguishes that the at least one object comprises at least one obstacle, and wherein the control unit calculates obstacle information of the at least one obstacle and plans the route for the vehicle according to the obstacle information.

5 . The warning sign placing apparatus according to claim 1 , wherein the control unit stops operating while the vehicle is traveling.

6 . The warning sign placing apparatus according to claim 1 further comprising:
a light-emitting unit, coupled to the control unit and having a light-emitting range, wherein the control unit plans the route for the vehicle according to the road within the light-emitting range.

7 . A control method of a warning sign placing apparatus, wherein the warning sign placing apparatus comprises at least two camera units and a vehicle, and wherein the method comprises:
capturing a plurality of images in a preset direction by the at least two camera units; identifying a traveling direction of a road based on the images and distinguishing at least one object on the road; and planning a route along the road for the vehicle according to the at least one object, wherein the vehicle travels along the route.

8 . The method according to claim 7 further comprising:
storing the route; and
receiving a recall signal, wherein the recall signal is used to instruct for controlling the vehicle to return back along the route.

9 . The method according to claim 7 , wherein the step of planning the route for the vehicle on the road according to the at least one object comprises:
distinguishing that the at least one object comprises a curb line; and calculating an angle between the curb line and a preset imaginary line, and controlling a traveling direction of the vehicle according to the angle.

10 . The method according to claim 7 , wherein the step of planning the route along the road for the vehicle according to the at least one object comprises:
distinguishing that the at least one object comprises at least one obstacle; and calculating obstacle information of the at least one obstacle, and planning the route for the vehicle according to the obstacle information.

11 . The method according to claim 7 further comprising:
planning the route for the vehicle according to the road within the light-emitting range.
