摘　　要：针对航拍图像中水上桥梁的自动识别问题进行研究,给出了水上桥梁的识别模型,分析了水上桥梁目标识别的影响因素,建立了基于直线提取的桥梁识别算法。该算法包括边缘检测、直线检测、平行直线对提取和水上桥梁标记等步骤。大量实验结果表明,提出的算法能准确识别水上桥梁目标,并且桥梁位置定位准确,是一种有效的方法。Focusing on automatically recognize bridge over water in military field by using aerial images in this article, a model to recognize bridge over water is provided, and some influential factor factors are analyzed, the basis of straight line pick-up is established in this article. This model includes edge detecting, straight line detecting, parallel straight line obtai- ning, labeling bridge over water and so on. This model is able to exactly recognize bridge over water and provide position of bridge over water in a great deal of experiment, which indicates it is an effective way.
