摘　　要：根据遥感影像路上桥梁的光谱特征和几何结构特征,提出了一种高分辨率遥感影像路上桥梁的识别方法。首先,利用道路矢量数据确定道路缓冲区,对缓冲区边缘进行检测与矢量化;然后,去除道路两边的防护带、道路上的车辆、道路绿化带、交通标志线等的干扰,以及去除桥梁本身的阴影确定路上桥梁的平行边;最后,利用几何参数完成路上桥梁目标的识别。试验结果表明,该方法能有效识别出高分辨率遥感影像路上桥梁。In this paper we propose a method of distinguis-hing road bridges in high-resolution remote sensing images based on spectral and geometric structural features. First, a path buffer using road vector data was determined, and edge detection and vectorization were done. Then the protective tape, vehicles, the green belt, traffic signal lines, and the shadow of the bridge itself were removed and the parallel edges of the bridge were obtained. Finally, road bridges were identified based on geometric parameters. Experimental results show that this method can effectively distinguish road bridges in high-resolution remote sensing image.
