Abstract

Example rotating camera systems and methods are described. In one implementation, an apparatus includes a motor having a camera mounting mechanism and configured to rotate a camera attached to the mounting mechanism. A communication module receives vehicle data from a vehicle. A rotation control module determines a current rotational orientation of the motor and determines a speed and direction to rotate the motor based on the received vehicle data.

Claims

1. An apparatus comprising:

a motor having a camera mounting mechanism and configured to rotate a camera mounted thereto;

a communication module configured to receive vehicle data from a vehicle; and

a rotation control module coupled to the motor and the communication module, the rotation control module configured to determine a current rotational orientation of the motor and determine a speed and direction to rotate the motor based on the received vehicle data;

wherein the vehicle data includes at least one of a current steering angle of the vehicle and a steering wheel rotation speed.

2. The apparatus of claim 1, wherein the rotation control module further determines the speed and direction to rotate the motor based on a desired orientation of the motor.

3. The apparatus of claim 1, further comprising an optical encoder coupled to the motor and the rotation control module, the optical encoder configured to monitor a rotational position of the motor.

4. The apparatus of claim 1, wherein the rotation control module limits the rotation of the motor to a pre-defined range of orientations.

5. The apparatus of claim 1, wherein the rotation control module includes a plurality of pre-defined ranges of orientation and the rotation control module limits the rotation of the motor to maintain the pre-defined ranges of orientation.

6. The apparatus of claim 1, wherein the mounting mechanism includes a mounting plate attached to a drive shaft of the motor, and wherein the mounting plate is configured to secure the camera in an orientation known to the rotation control module.

7. The apparatus of claim 1, wherein the motor, communication module, and rotation control module are mounted outside the vehicle.

8. The apparatus of claim 1, further comprising a vehicle mounting device configured to attach the apparatus to a vehicle.

9. The apparatus of claim 4, wherein the pre-defined range of orientations is selected by a user of the camera.

10. An apparatus comprising:

a motor having a camera mounting mechanism and configured to rotate a camera mounted thereto;

a communication module configured to receive vehicle data from a vehicle; and

a rotation control module coupled to the motor and the communication module, the rotation control module configured to determine a current rotational orientation of the motor and determine a speed and direction to rotate the motor based on the received vehicle data

wherein a user of the vehicle determines an offset value further used by the rotation control module to determine the speed and direction to rotate the motor.

11. A method comprising:

receiving a desired orientation of a motor mounted to a vehicle, the motor having a camera mounted thereto;

receiving vehicle data associated with the vehicle;

determining, using one or more processors, whether to rotate the motor based on the desired orientation of the motor and the received vehicle data;

responsive to determining to rotate the motor;

determining, using the one or more processors, which direction to rotate the motor;

determining, using the one or more processors, a number of degrees to rotate the motor;

determining, using the one or more processors, a speed to rotate the motor; and

generating, using the one or more processors, instructions to rotate the motor based on the direction to rotate the motor, the number of degrees to rotate the motor, and the speed to rotate the motor;

wherein the vehicle data includes a current steering angle of the vehicle.

12. The method of claim 11, further comprising communicating the instructions to the motor.

13. The method of claim 11, further comprising receiving current rotational position data from the motor.

14. The method of claim 11, wherein the desired orientation of the motor includes a pre-defined range of orientations.

15. The method of claim 11, wherein the desired orientation of the motor includes a plurality of pre-defined ranges of orientations.

16. An apparatus comprising:

a motor having a camera mounting mechanism and configured to rotate a camera mounted thereto;

a communication module configured to receive vehicle data from a vehicle, the vehicle data including a steering wheel rotation speed and steering wheel angle; and

a rotation control module coupled to the motor and the communication module, the rotation control module configured to determine a current rotational orientation of the motor and a desired orientation of the motor, the rotation control module further configured to determine a direction, a speed, and a number of degrees to rotate the motor based on the desired orientation of the motor and the steering wheel rotation speed and the steering wheel angle.

17. The apparatus of claim 16, wherein the rotation control module limits the rotation of the motor to a pre-defined range of orientations.
