Abstract

Disclosed are devices, systems and methods for using a rotating camera for vehicular operation. One example of a method for improving driving includes determining, by a processor in the vehicle, that a trigger has activated, orienting, based on the determining, a single rotating camera towards a direction of interest, and activating a recording functionality of the single rotating camera, where the vehicle comprises the single rotating camera and one or more fixed cameras, and where the single rotating camera provides a redundant functionality for, and consumes less power than, the one or more fixed cameras.

First claim

What is claimed:

1. A method for improving driving of a vehicle, comprising:
controlling the vehicle to operate on a first route;
prior to the vehicle arriving at an area along the first route, generating a first information of the area by combining information from a map module and a perception module;
determining, by a processor in the vehicle, that an additional visual information is required for vehicle operation in the area based on the first information;
controlling a rotating camera to turn into a direction upon the determining that the additional visual information is required;
receiving, by the processor, a second information from the rotating camera; and
controlling the vehicle to operate on a second route based on the received second information.

2. The method of claim 1 , wherein first information comprises 1) information of road and intersection, 2) information of real-time traffic and construction, or 3) information related to adjacent vehicles and pedestrians.

3. The method of claim 1 , wherein the second information comprises a view of an intersection or an area of concern.

4. The method of claim 1 , further comprising:
determining, by the processor upon receiving the second information, a road condition is safe for the vehicle to proceed based on the second information.

5. The method of claim 4 , wherein the determining is further based on a third information received from at least one sensor.

6. The method of claim 4 , further comprising controlling the vehicle to proceed under the road condition upon determining the road condition is safe for the vehicle to proceed.

7. The method of claim 1 , further comprising configuring a second rotating camera to assist monitoring when the determining of road condition is not fully monitored based on the second information.

8. The method of claim 7 , further comprising receiving a third information monitored by the second rotating camera and selecting an alternative route for the vehicle to operate when the determining of road condition is fully monitored based on the second information and the third information.

9. The method of claim 1 , wherein determining that the additional visual information is required in the area comprises determining an obstruction in the area by the perception module.

10. The method of claim 9 , wherein the rotating camera is controlled to turn into the direction associated with a location of the obstruction.

11. A system for improving driving of a vehicle, comprising:
at least one rotating camera;
at least two modules;
a processor; and
a memory comprises instructions stored thereupon, wherein the instructions when executed by the processor configure the processor to:
control the vehicle to operate on a first route;
prior to the vehicle arriving at an area along the first route, generate a first information of the area by combining information from a map module and a perception module;
determine, by the processor, that an additional information is required based on the first information;
control a rotating camera in the at least one rotating camera to turn into a certain direction upon the determining that the additional information is required;
receive, by the processor, a second information from the rotating camera; and
control the vehicle to operate on a second route based on the received second information.

12. The system of claim 11 , wherein the information monitored by the rotating camera comprises visual information that is used to maneuver an intersection.

13. The system of claim 11 , wherein the at least two modules comprise a map module and a perception module.

14. The system of claim 13 , wherein the map module monitors information related to road and intersection.

15. The system of claim 13 , wherein the perception module monitors information related to real-time traffic and/or construction, or information related to adjacent vehicles and/or pedestrians.

16. The system of claim 11 , wherein the instructions when executed by the processor further configure the processor to:
determine, whether a road condition is safe for the vehicle to proceed based on the second information.

17. The system of claim 11 , further comprising a clean system coupled to the rotating camera, wherein the clean system ensures the rotating camera remains clean.

18. The system of claim 17 , wherein the clean system comprises a sprayer and a wiper.

19. A device for improving driving of a vehicle, comprising:
a processor; and
a memory including instructions stored thereupon, the instructions upon execution by the processor causing the processor to:
control the vehicle to operate on a first route;
prior to the vehicle arriving at an area along the first route, generate a first information of the area by combining information from a map module and a perception module;
determine that an additional visual information is required based on the first information;
control a first rotating camera to turn into a certain direction based upon the determining that the additional visual information is required;
receive a second information from the first rotating camera; and
control the vehicle to operate on a second route based on the received second information.

20. The device of claim 19 , wherein the instructions upon execution by the processor further cause the processor to determine an intersection or an area of concern is covered based on the second information.

21. The device of claim 19 , wherein the instructions upon execution by the processor further cause the processor to
determine an intersection or an area of concern is not fully monitored based on the second information;
initiate a second rotating camera to turn to a second direction upon determining the intersection or the area of concern is not fully monitored; and
receive a third information monitored by the second rotating camera.

22. The device of claim 21 , wherein the instructions upon execution by the processor further cause the processor to select an alternative route for the vehicle based on the second information and/or the third information.
