Abstract

Most studies on automatic airport recognition from remote sensing images focus on extracting straight lines to identify airport runways, and then determine the airport target. However, straight line not only is an indicator of airport runways, but also indicates presence of highways, railways, and external walls of large-scale plants, marginal lands, mountains, formations, and other structures. Furthermore, these methods work well mainly on a single and large airport instead of small ones. Few of them have studied multiple targets. In this paper, TM satellite imagery is used as source to detect airports. Traditional spatial filter and edge-detection methods tend to fail in airport detection because of noise and false edges. This paper presents a new method that combines edge tracing and SURF to extract airports from images. Firstly, Gaussian filter is applied to suppress noise. Then, gradient magnitudes and gradient directions are calculated. Large local variations of gradients detected by improved non-maximum suppression (NMS) method are removed to obtain a single-pixel edge image. A contour line is extracted from this edge image. Finally, airports are detected through line detection and SURF. Airports in TM images are successfully recognized using the presented method. The airport detection method proposed in this paper is suitable not only for remote-sensing data of TM satellites but also for application on day-painting satellites, such as other remote-sensing satellite data.
