Automated representation of complete visible range
Reliable and exact assessment of visibility is essential for safe air traffic. In order to overcome the drawbacks of the currently subjective reports from human observers, an approach to automatically derive visibility measures by means of image processing was developed. It is based on identification of visibility of individual landmarks and compiling an overall visibility range. The methods used are based on concepts of illumination compensation as well as structural (edges) and texture recognition. Validation on individual landmarks showed a reliable performance of 96% correct detections.
