The Visibility Estimation through Image Analytics (VEIA) system provides air traffic managers and pilots an effective way to automatically extract data about meteorological visibility from cameras. The system uses edge detection that is sensitive to changes in the visual scene to compare the overall edge strength of the current image to edges of an image of a clear day to estimate visibility in miles. With the proliferation of web-based camera imagery for monitoring conditions near airports and remote locations, VEIA can expand the number of visibility observations, especially in areas not covered by traditional sensor systems and where low visibility can have dire consequences.
