INTELLIGENT ROADSIDE UNIT, CONTROL METHOD AND STORAGE MEDIUM
The present disclosure proposes an intelligent roadside unit and a control method. The intelligent roadside unit includes: a circular track; a camera disposed on the circular track and movable along the circular track; a driver for driving the camera; a circular radar array, wherein the circular radar array includes a plurality of radars detecting obstacle information in different directions of a road respectively; and a controller configured to judge whether there is a vehicle approaching and to acquire an approach direction of the vehicle according to the obstacle information detected by the radar, and to control the driver to drive the camera toward the approach direction for shooting.
1 . An intelligent roadside unit, comprising:
a circular track;
a camera disposed on the circular track and movable along the circular track;
a driver for driving the camera;
a circular radar array, wherein the circular radar array comprises a plurality of radars detecting obstacle information in different directions of a road respectively; and
a controller configured to judge whether there is a vehicle approaching and to acquire an approach direction of the vehicle according to the obstacle information detected by the plurality of radars, and to control the driver to drive the camera toward the approach direction for shooting.
2 . The intelligent roadside unit according to claim 1 , wherein the plurality of radars of the circular radar array are millimeter-wave radars or laser radars.
3 . The intelligent roadside unit according to claim 1 , wherein when an obstacle detected by the radars approaches the intelligent roadside unit, the controller judges that the vehicle being approaching is detected.
4 . The intelligent roadside unit according to claim 1 , further comprising:
a shielding layer wrapping at least a part of the camera.
5 . The intelligent roadside unit according to claim 1 , wherein the controller generates a point cloud image according to an image captured by the camera and the obstacle information detected by the radars.
6 . The intelligent roadside unit according to claim 5 , further comprising:
a communicator coupled to the controller, the controller being configured to send the point cloud image to an automatic car or a server close to the intelligent roadside unit through the communicator.
7 . The intelligent roadside unit according to claim 6 , further comprising:
traffic lights, the controller being configured to control the traffic lights according to the point cloud image.
8 . A control method applied to an intelligent roadside unit, comprising:
acquiring obstacle information in different directions of a road detected by a circular radar array, wherein the circular radar array comprises a plurality of radars detecting obstacle information in different directions of a road respectively;
judging whether there is a vehicle approaching and acquiring an approach direction of the vehicle according to the obstacle information detected by the radars, and
controlling a driver to drive a camera toward the approach direction for shooting, wherein the camera is disposed on a circular track and movable along the circular track.
9 . The control method according to claim 8 , wherein the plurality of radars of the circular radar array are millimeter-wave radars or laser radars.
10 . The control method according to claim 8 , further comprising
when an obstacle detected by the radars approaches the intelligent roadside unit, judging that the vehicle being approaching is detected.
11 . The control method according to claim 8 , wherein at least a part of the camera is wrapped by a shielding layer.
12 . The control method according to claim 8 , further comprising:
generating a point cloud image according to an image captured by the camera and the obstacle information detected by the radars.
13 . The control method according to claim 12 , further comprising:
sending the point cloud image to an automatic car or a server close to the intelligent roadside unit through the communicator.
14 . The control method according to claim 13 , further comprising:
controlling traffic lights according to the point cloud image.
15 . A non-transitory computer readable storage medium having a computer program stored thereon, wherein the program implements a control method when executed by a processor, and the method comprises:
acquiring obstacle information in different directions of a road detected by a circular radar array, wherein the circular radar array comprises a plurality of radars detecting obstacle information in different directions of a road respectively;
judging whether there is a vehicle approaching and acquiring an approach direction of the vehicle according to the obstacle information detected by the radars, and
controlling a driver to drive a camera toward the approach direction for shooting, wherein the camera is disposed on a circular track and movable along the circular track.
