Abstract

An image acquisition and display system 10 is provided for use on a vehicle. System 10 includes a three-dimensional display and two stereo camera pairs 18, 20 and 22, 24 which are respectively mounted on the driver-side and passenger-side of the vehicle. Camera pairs 18, 20 and 22, 24 are adapted to receive images of objects located in the front of the vehicle from both sides of the vehicle regardless of the ambient light level surrounding the vehicle. A controller 14 processes the image data from cameras 18-24 and provides three-dimensional image data to display 12 which utilizes the data to display the images to the driver 52 in a three-dimensional format. A user input device 26 allows a driver 52 of the vehicle to select between camera pairs 18, 20 and 22, 24, to reposition camera pairs 18, 20 and 22, 24, and to selectively magnify and minimize images acquired by cameras pairs 18,20 and 22,24.

Claims

1. An image acquisition and display system for use with a vehicle comprising:

a first stereo camera pair which is mounted on a driver-side of said vehicle and which is effective to acquire and transmit first three-dimensional image data;

a second stereo camera pair which is mounted on a passenger-side of said vehicle and which is effective to acquire and transmit second three-dimensional image data;

a controller which is communicatively coupled to said first and second stereo camera pairs and which is effective to receive and process said first and second three-dimensional image data and to transmit a signal representing said processed image data; and

a three-dimensional display assembly which is communicatively coupled to said controller and which is effective to receive said signal and to display said processed image data in a three-dimensional format.

2. The system of claim 1 wherein said first stereo camera pair is operatively disposed within a driver-side mirror shroud and wherein said second stereo camera pair is operatively disposed within a passenger-side mirror shroud.

3. The system of claim 1 further comprising:

a user input device which is communicatively coupled to said controller and which is effective to receive commands from an operator and to transmit said commands to said controller; and

wherein said controller is further effective to utilize said commands to operate said first and second stereo camera pairs.

4. The system of claim 3 wherein said commands comprise camera selection commands which are effective to allow a user to selectively acquire and view images from said first stereo camera pair or said second stereo camera pair.

5. The system of claim 4 wherein said commands further comprise zoom commands which allow a user to selectively magnify and minimize images acquired by said first and second stereo camera pairs.

6. The system of claim 3 wherein said user input device comprises a microphone and voice recognition software.

7. The system of claim 3 wherein said user input device comprises a manual input device.

8. The system of claim 1 wherein said first and second stereo camera pairs comprise infrared illuminators.

9. The system of claim 1 wherein said first and second stereo camera pairs are directed in front of said vehicle.

10. The system of claim 1 further comprising:

a first motor assembly on which said first stereo camera pair is mounted and which is effective to selectively rotate and pivot said first stereo camera pair; and

a second motor assembly on which said second stereo camera pair is mounted and which is effective to selectively rotate and pivot said second stereo camera pair.

11. The system of claim 1 wherein said controller comprises image recognition software which is effective to identify objects which are within a field of view of said first and second camera pair based upon image data provided by said objects.

12. An image acquisition and display system for use with a vehicle comprising:

a first stereo camera pair which is mounted on a first side of said vehicle and which selectively receives and provides image data from said first side of said vehicle;

a second stereo camera pair which is mounted on a second side of said vehicle and which selectively receives and provides image data from said second side of said vehicle;

a user input device which is effective to receive and transmit a camera selection command from a user;

a controller which is communicatively coupled to said first and second stereo camera pairs and to said user input device, said controller being effective to receive said camera selection command and to selectively activate said first or said second stereo camera pair based upon said camera selection command, said controller further being effective to receive and process image data received from said activated camera pair and to transmit said processed image data; and

a three-dimensional display assembly which is communicatively coupled to said controller and which is effective to receive said processed image data and to display said processed image data in a three-dimensional format.

13. The image acquisition and display system of claim 12 wherein said display assembly comprises a flat panel display.

14. The image acquisition and display system of claim 12 wherein said display assembly comprises a holographic display.

15. The image acquisition and display system of claim 12 wherein said first stereo camera pair is mounted in a driver-side mirror shroud of said vehicle and said second stereo camera pair is mounted in passenger-side mirror shroud of said vehicle.

16. The image acquisition and display system of claim 12 wherein said controller is further effective to selectively and simultaneously activate a unique one of said first stereo camera pair and a unique one of said second stereo camera pair, and to utilize said activated cameras to acquire images remote from said vehicle with improved resolution.

17. A method for acquiring and displaying images for use with a vehicle and comprising the steps of:

providing a three-dimensional display;

mounting said display within said vehicle;

providing a first and a second stereo camera pair;

mounting said first stereo camera pair on a driver-side of said vehicle;

mounting said second stereo camera pair on a passenger-side of said vehicle;

selectively acquiring images from said first and said second stereo camera pair; and

selectively displaying said acquired images in a three-dimensional format on said display.

18. The method of claim 17 wherein said first and second stereo camera pair include infrared illuminators, said method further comprising the steps of:

monitoring an ambient light level surrounding said vehicle; and

automatically activating said infrared illuminators when said ambient light level falls below a predetermined threshold.

19. The method of claim 17 further comprising the steps of:

providing pattern and image recognition software;

utilizing said pattern and image recognition software to identify said acquired images; and

selectively providing a notification of said identity of said acquired images.

20. The method of claim 19 wherein said notification comprises an audible notification.
