Abstract

Video aids are disclosed to assist vehicle drivers for all phases of vehicle control and driving conditions. In one exemplary embodiment, a driver'"'"'s vision augmentation system is flexibly configured for installation on virtually any vehicle for real-time video display to the vehicle driver of each tire'"'"'s contact with the ground. Such a driver'"'"'s vision augmentation system can improve one'"'"'s ability to drive in off-road conditions, e.g., through an otherwise impassable terrain, in order to increase survivability and improve chances for mission success.

Claims

1. A vision augmentation system for installation on a vehicle to provide video aids to assist vehicle drivers, comprising:

a plurality of cameras providing video inputs;

a quad video processor powered by a power source, wherein the quad video processor receives the video inputs from the cameras and outputs an appropriate video display; and

a touch screen display to receive the output from the quad video processor and display said appropriate video display, the touch screen display being separately connected to a converter unit for touch screen connection back to the quad video processor for touch-screen control of said appropriate video display.

2. The vision augmentation system recited in claim 1, wherein the power source can be either an internal battery or an externally connected power source.

3. The vision augmentation system recited in claim 1, further comprising a digital video recorder, wherein the quad video processor is connected to the digital video recorder and the touch screen display.

4. The vision augmentation system recited in claim 1, wherein the cameras are mounted around a periphery of the vehicle to allow its driver to see the immediate area around each tire of the vehicle to enhance the vehicular off-road mobility, safety and situation awareness.

5. The vision augmentation system recited in claim 1, wherein four video cameras are deployed around the vehicle having front and rear wheels, two of the cameras being mounted on a respective bracket behind a respective rear wheel looking forward;

a third camera being placed on a front of the vehicle for a frontal view; and

a fourth camera being placed on a rear of the vehicle for a rear view.

6. The vision augmentation system recited in claim 1, wherein touching a segmented area of the touch screen can switch between a full-screen view of a chosen camera and a return to a quad display mode.

7. The vision augmentation system recited in claim 1, further comprising a flash-memory based digital video recorder configured to provide an audio and/or video record of video events for later review.

8. A vision augmentation method to provide video aids to assist a vehicle driver, comprising:

choosing video cameras for operation in a select portion of the electromagnetic spectrum;

configuring said video cameras around an exterior of a vehicle to provide video inputs of respective real-time imagery, including video inputs of ground tire contacts;

providing a touch screen display capable of displaying said real time imagery in a quadrant display layout;

providing a control unit powered by a power source, wherein a programmable video quad unit inside the control unit receives the video inputs from the cameras and sends the appropriate video display to the touch screen display; and

providing a control capability to switch between a full screen view of any selected camera input and a quad screen display with the use of the touch screen display.

9. The vision augmentation method recited in claim 8, wherein a number of cameras are placed to the rear of the vehicle to look forward, a camera is provided for a front view and a camera is provided for a rear view, wherein videos from these cameras are input for display to the driver in a quad view arranged to represent vehicle situation awareness.

10. The vision augmentation method recited in claim 8, wherein if the driver touches one of the quadrants of the display, the touch screen display switches to a full-screen view of the quadrant image, and when touched again, the touch screen display reverts to a normal quad mode.

11. The vision augmentation method recited in claim 8, wherein a digital video recorder using compact flash media can be installed should video recording be desired.

12. The vision augmentation method recited in claim 8, wherein video cameras are placed behind rear wheels with the use of extension brackets that are attached to the vehicle based on fasteners.

13. The vision augmentation method recited in claim 8, wherein during hours of darkness, Cadmium Sulfide sensors associated with low intensity IR illuminated cameras automatically activate LED illumination to provide adequate illumination to drive under the cover of darkness.

14. The vision augmentation method recited in claim 8, wherein any one of the video sources can be switched to and from the full-screen mode with the use of the touch screen of the display.
