| 摘 要： | 提出了一种能够自动识别全景图中建筑物轮廓的方法.首先利用Canny算子获得边缘图像,使用霍夫变换算法提取出边缘图像中的直线.然后检测各条直线之间的位置关系,由于全景图尺寸较大,采用了局部化原理来进行检测.再根据直线之间的位置关系生成直线关系图.最后遍历直线关系图得到封闭几何图形,从而识别出大规模全景图中的建筑物轮廓,为进一步的全景图中建筑物三维建模提供素材.算法分析和实验结果表明,该方法对于几何形状规则的建筑物能够较好的识别.

| Abstract: | In order to build 3D model of buildings in panorama,the method based on Canny algorithm and hough transform is used to replace the current work.A method to automatically detect the building profile in panorama is proposed.Firstly,the algorithm of line extraction and line merging using hough transform is presented.Then the line＇s relation graph is generated based on localization principle.At last,the closed geometric figure is selected according to the line-relationship graph to detect the building profile in the large panorama.The results dedicate that the method can well detect the building in regular geometric shape. |
