Abstract In this paper, the proplem how to detect and recognize the airport runway marking in images is discussed. These images are obtained by a landing unmanned air vehicle (UAV) based on vision. Some spots of high light are extracted and grouped into several small clusters using a special clustering algorithm. An identification model is constructed using the perspective model, the rectangular flatplate constraint and the prior views of the scene constraint conditions. Then the runway spots in these clusters using this identification model can be datected. The computational time is greatly cut down by this classification process. The experimental results show that the proposed algorithm is very suited to the landing of UAV.
