摘　　要：针对远距离高空航拍图像中桥梁目标的典型场景,提出了一种基于知识的桥梁目标识别方法,完成了远距离高空航拍图像中桥梁目标的检测.本算法根据水域、陆地域和桥梁域三者之间的关系以及桥梁域自身的特点,采取先假设后验证的方法确定桥梁域.在实验中取得了较好的识别效果.Through analysis of the features of bridge objects in long-rang air-plane images, a knowledge-based method for bridge recognition is proposed in this paper. In this method, according to the relation among land, bridge and river, and the feature of bridge to identify the bridge locations using the method which makes suppose in the first and does verification in the second. The method proves to be very effective in the experiments.
