Motor vehicle having a wheel-view camera and method for controlling a wheel-view camera system
First Claim
1. A motor vehicle, comprising:
- a vehicle body;
front wheels;
a wheel-view camera with a wide-angle lens and an image sensor, said wheel-view camera being mounted on said vehicle body and pointing in a downward direction such that said wheel-view camera captures one of said front wheels;
an image processing unit operatively connected to said wheel-view camera for receiving image data from said wheel-view camera, said image processing unit being configured to process the image data such that said image processing unit performs a wide-angle lens correction, an image rotation and a viewpoint conversion;
a display unit operatively connected to said image processing unit, said display unit receiving processed image data from said image processing unit and displaying an image of said one of said front wheels;
said vehicle body having a side view mirror with a housing;
said wheel-view camera being mounted in said housing of said side view mirror;
said image processing unit performing the viewpoint conversion such that said display unit displays an image having a virtual viewpoint positioned at a given distance away from said side view mirror and looking down toward said one of said front wheels;
a control unit operatively connected to said image processing unit;
vehicle sensors operatively connected to said control unit, said vehicle sensors providing vehicle sensor data to said control unit;
said control unit controlling said image processing unit in dependence on the vehicle sensor data;
said vehicle sensors including a steering angle sensor for providing steering angle data to said control unit; and
said control unit controlling said image processing unit in dependence on the steering angle data such that said display unit displays a relatively smaller portion of a side of said vehicle body in case of a relatively smaller steering angle and such that said display unit displays a relatively larger portion of a side of said vehicle body in case of a relatively larger steering angle.

Abstract
A motor vehicle has a wheel-view camera with a wide-angle lens and an image sensor. The wheel-view camera is mounted in the housing of a side view mirror and points in a downward direction such that the wheel-view camera captures a front wheel. An image processing unit is operatively connected to the wheel-view camera unit for receiving image data from the wheel-view camera. The image processing unit is configured to process the image data such that the image processing unit performs a wide-angle lens correction, an image rotation and a viewpoint conversion. A display unit is operatively connected to the image processing unit. The display unit receives processed image data from the image processing unit and displays an image of the front wheel.

10. A method for controlling a wheel-view camera system, the method which comprises:
-
providing a wheel-view camera having a wide-angle lens, the wheel-view camera being mounted on a body of a vehicle and pointing in a downward direction such that the wheel-view camera captures a front wheel of the vehicle; processing image data from the wheel-view camera by performing a wide-angle lens correction, an image rotation and a viewpoint conversion; transmitting processed image data to a display unit provided in the vehicle; displaying, with the display unit, an image of the front wheel of the vehicle such that the display unit displays an image having a virtual viewpoint positioned at a given distance away from a side view mirror of the vehicle and looking down toward the front wheel of the vehicle; and processing image data from the wheel-view camera in dependence on steering angle data such that the display unit displays a close-up view of the front wheel in case of a relatively smaller steering angle and such that said display unit displays a wide-angle view in case of a relatively larger steering angle. - View Dependent Claims (11, 12, 13, 14)

15. A method for controlling a wheel-view camera system, the method which comprises:
-
providing a wheel-view camera having a wide-angle lens, the wheel-view camera being mounted on a body of a vehicle and pointing in a downward direction such that the wheel-view camera captures a front wheel of the vehicle; processing image data from the wheel-view camera by performing a wide-angle lens correction, an image rotation and a viewpoint conversion; transmitting processed image data to a display unit provided in the vehicle; displaying, with the display unit, an image of the front wheel of the vehicle such that the display unit displays an image having a virtual viewpoint positioned at a given distance away from a side view mirror of the vehicle and looking down toward the front wheel of the vehicle; and processing image data from the wheel-view camera in dependence on vehicle speed data such that the display unit displays a close-up view of the front wheel in case of a relatively smaller vehicle speed and such that the display unit displays a wide-angle view in case of a relatively larger vehicle speed.
