A Forward-looking Runway Recognition Algorithm Based on Improved Hough Transform

A recognition algorithm for forward-looking runway is presented based on improved Hough transform.The forward-looking runway is defined as a pair of linear edges,which are unifications of both the gradient direction and the line direction. With this definition the traditional Hough transform based on binary edge image is improved in order to extract the straight runway lanes form complex background. It is demonstrated to be a practical approach to runway recognition for the good simulation results on real images.
