Traffic system for enhancing driver visibility
First Claim
1. A method comprising:
- detecting a vehicle traveling along a roadway;
receiving data from a plurality of fog detectors located proximate the roadway;
determining, based on the data from the plurality of fog detectors, that fog is present about the roadway, wherein the fog limits visibility of the roadway;
obtaining, after the determining that fog is present about the roadway, a plurality of images of the roadway by activating a plurality of cameras, including a first image from a first camera of the plurality of cameras and a second image from a second camera of the plurality of cameras, wherein the cameras are spaced along the roadway and configured to capture different portions of the roadway that are visible through the fog, and wherein each of the images includes one of the different portions of the roadway that is visible through the fog;
shrinking the second image and positioning the second image over the first image in accordance with a perspective of a driver to create a composite image, wherein the composite image includes two or more of the different portions of the roadway that are visible through the fog, and wherein the composite image shows the roadway unobstructed by fog; and
transmitting the composite image to a display device located in a vehicle traveling along the roadway.

6. A system comprising:
-
a fog detection unit configured to determine fog is present near a roadway, wherein the fog limits visibility of the roadway; a plurality of cameras located proximate the roadway, wherein the cameras are spaced along the roadway and configured to capture images, including a first image from a first camera of the plurality of cameras and a second image from a second camera of the plurality of cameras, wherein the images include different portions of the roadway that are visible through the fog; an activation unit configured to activate the plurality of cameras after fog is detected near the roadway; a roadway imaging unit configured to; receive the first image and the second image, and, shrink the second image and position the second image over the first image in accordance with a perspective of a driver to create a composite image, wherein the composite image includes two or more of the different portions of the roadway that are visible through the fog, and wherein the composite image shows the roadway unobstructed by fog; and a transceiver unit configured to send a signal that detects vehicles on the roadway, and to send the composite image to the vehicles traveling on the roadway. - View Dependent Claims (7, 8, 9, 10)
