System for enhancing the visibility of a ground surface adjacent to a land vehicle
First Claim
1. A system for displaying an image of a ground surface condition adjacent a land vehicle, the system comprising:
- a mobile communication device supported on the vehicle for movement therewith;
a hand-held communication device operative to produce a signal containing identification data which identifies the hand-held device wherein the mobile device is operative to receive the signal and remove the identification data from the signal;
control logic coupled to the mobile device and operative to determine if the hand-held device is an authorized hand-held device based on the identification data;
an imaging assembly supported on the vehicle to obtain an image of the ground;
an image processor to process the image to detect the condition on the ground surface, the control logic being operative to generate a display command signal; and
a display device responsive to the display command signal to display an actual image of the detected condition onto or adjacent the vehicle above the ground surface for viewing by an approaching pedestrian when the pedestrian carrying the authorized hand-held device is located within a predetermined range of the mobile device.

Abstract
A system for enhancing the visibility of a ground surface adjacent to a land vehicle is provided. The system includes a mobile communication device, a hand-held communication device and control logic coupled to the mobile device and operative to determine if the hand-held device is an authorized device. An imaging assembly is supported on the vehicle to obtain an image of the ground surface. An image processor processes the image to detect an obstacle located on the ground surface. The control logic is operative to generate a display command signal. A display device is responsive to the signal to display in real time the detected obstacle or a welcome mat onto or adjacent the vehicle for enhanced viewing by an approaching pedestrian when the pedestrian carrying the authorized device is located within a predetermined range of the mobile device.
