Video system for monitoring and reporting weather conditions
First Claim
1. A computerized method for determining a weather condition using visible imagery comprising the steps:
- receiving a plurality of sequential visible images each depicting substantially the same field of view;
determining based on the received plurality of sequential visible images, a composite visible image depicting the field of view;
generating a first and second edge-detected images based on one of the plurality of sequential visible images and the composite visible image, respectively;
comparing the fist and second edge-detected images; and
determining a weather condition based on the comparison of edge-detected images.

Abstract
A method and apparatus for identifying a weather condition from visible imagery. A sequential series of visible images depicting a field of view is received. A composite visible image representing a long-term average of the monitored field of view is maintained and updated with each subsequent image. Each received image and the composite visible image are edge-detection filtered. Persistent edges existing in both the received image and the composite visible image are extracted and used to predict a weather condition. In one embodiment, a statistical value determined from the extracted edge image is used to predict visibility using a predetermined scoring function.
