Abstract

Camera control systems and methods for providing a dynamic view of the environment outside of a vehicle are presented. One or more cameras are configured to capture at least one view of the environment outside of the vehicle. Control circuitry detects at least one of the speed of the vehicle and the pitch angle of the vehicle (e.g., by using a speedometer and inclinometer). The control circuitry selects a view angle based on the at least one of the speed of the vehicle and the pitch angle of the vehicle. The control circuitry then displays, based on an output of the at least one camera, a view of the environment outside of the vehicle from the selected view angle on a display of the vehicle.

First claim

What is claimed is:

1. A system comprising:
at least one camera configured to capture data associated with at least one real view of environment outside of the vehicle;
a display for generating at least one virtual view of the environment outside of the vehicle based on the data captured using the at least one camera; and
a control circuitry configured to:
detect a pitch angle of the vehicle;
select a position of a virtual camera in relation to a length of the vehicle, wherein:
the position of the virtual camera is selected to be ahead of a front of the vehicle when pitch angle of the vehicle is above a threshold; and
the position of the virtual camera is selected to be behind the front of the vehicle when pitch angle of the vehicle is below the threshold;

generate a virtual view of the environment outside of the vehicle from the selected position of the virtual camera based on the data captured using the at least one camera; and
provide for display of the generated virtual view on the display of the vehicle.

2. The system of claim 1 wherein the control circuitry is configured to generate the virtual view by extrapolating an image based on the data captured using the at least one camera.

3. The system of claim 1 wherein the control circuitry is configured to generate the virtual view by combing data captured using two or more cameras.

4. The system of claim 1 , wherein the control circuitry is further configured to:
adjust the position of the virtual camera in relation to the length of the vehicle proportionally to a change in the pitch angle of the vehicle.

5. The system of claim 1 , wherein the control circuitry is further configured to:
display a predicted path of front wheels of the vehicle overlaid over the virtual view.

6. The system of claim 1 , wherein the control circuitry is configured to generate the virtual view of the environment outside of the vehicle from the selected position of the virtual camera by:
generating a view that approximates a view of the environment outside of the vehicle that would be captured by a real camera if it was placed in the selected position of the virtual camera.

7. A method, the method comprising:
capturing, using at least one camera, data associated with at least one real view of environment outside of a vehicle;
detecting, using control circuitry a pitch angle of the vehicle;
selecting, using the control circuitry, a position of a virtual camera in relation to a length of the vehicle, wherein:
the position of the virtual camera is selected to be ahead of a front of the vehicle when pitch angle of the vehicle is above a threshold; and
the position of the virtual camera is selected to be behind the front of the vehicle when pitch angle of the vehicle is below the threshold;

generating, using the control circuitry, a virtual view of the environment outside of the vehicle from the selected position of the virtual camera based on the data captured using the at least one camera; and
providing for displaying, on a display of the vehicle, the generated virtual view on the display of the vehicle.

8. The method of claim 7 , wherein generating the virtual view comprises extrapolating an image based on the data captured using the at least one camera.

9. The method of claim 7 , wherein generating the virtual view comprises combing data captured using two or more cameras.

10. The method of claim 7 , further comprising:
adjusting the position of the virtual camera in relation to the length of the vehicle proportionally to a change in the pitch angle of the vehicle.

11. The method of claim 7 , further comprising:
adjusting the position of the virtual camera in relation to the length of the vehicle proportionally to a change in the speed of the vehicle.

12. A non-transitory computer readable medium having instructions encoded thereon, that when executed by control circuitry of a vehicle causes the control circuitry to:
capture, using at least one camera, data associated with at least one real view of environment outside of the vehicle;
detect a pitch angle of the vehicle;
selecting a position of a virtual camera in relation to a length of the vehicle, wherein:
the position of the virtual camera is selected to be ahead of a front of the vehicle when pitch angle of the vehicle is above a threshold; and
the position of the virtual camera is selected to be behind the front of the vehicle when pitch angle of the vehicle is below the threshold;

generate a virtual view of the environment outside of the vehicle from the selected position of the virtual camera based on the data captured using the at least one camera; and
provide for display, on a display of the vehicle, the generated virtual view on the display of the vehicle.

13. The method of claim 7 , further comprising:
displaying a predicted path of front wheels of the vehicle overlaid over the virtual view.

14. The method of claim 1 , wherein the generating the virtual view of the environment outside of the vehicle from the selected position of the virtual camera comprises:
generating a view that approximates a view of the environment outside of the vehicle that would be captured by a real camera if it was placed in the selected position of the virtual camera.

15. The system of claim 1 , wherein:
the position of the virtual camera is selected to be ahead of the front of the vehicle when pitch angle of the vehicle is above a threshold to provide a view of a terrain that wheels of the vehicle are about to drive over; and
the position of the virtual camera is selected to be behind the front of the vehicle when pitch angle of the vehicle is below the threshold to provide increased angle of view of terrain ahead of the vehicle.
