【摘要】 针对低空航拍图像中水上桥梁目标的自动识别技术,提出了一种水域特征与桥梁结构特征相结合的桥梁识别算法。首先对图像进行粗略分割,去除部分干扰区域;然后在分割图像的基础上进行Hough变换,提取桥梁相关直线;最后利用桥梁知识模型的指导,进行桥梁特征匹配,实现桥梁的精确提取。实验结果表明,该算法对低空航拍图像中的水上桥梁能够有效地加以识别。更多还原

【Abstract】 For solving the automatic recognition of bridge in low altitude aerial image,a method of bridge recognition based on the combination of water features and bridge structure feature is proposed.First,segmentation of the low altitude aerial image using Otsu algorithm was adopted to remove some interference region;then,the Hough transform to extract the bridge lines was made;finally,the bridge target was recognized with the guidance of bridge knowledge model and through the bridge feature It is experimentally shown that the bridge over rivers can be correctly recognized.更多还原
