| 摘 要： | 提出一种基于两视图的曲面物体自动重建方法. 采用基于Haudorff距离的特征匹配技术对图像的正面和侧面中的曲面物体进行匹配,自动获得图像中物体的大致形状及位置信息. 采用基于形状先验的图像分割算法自动地将曲面物体从图像的正面和侧面中分割出来. 利用这两幅图像中获得的侧影轮廓线,实现曲面自动重建和纹理自动提取. 通过真实曲面物体进行重建实验,验证了该方法的可行性.

| Abstract: | A method of automatic curved object reconstruction from two views is proposed.Hausdorff distance based feature matching technique is used for matching the curved objects in the frontal and lateral views.So the approximate shape and location information of the desired objects can be automatically obtained.Objects in the two views can be automatically segmented out by the shape priors based image segmentation algorithm.As a result,curved surface reconstruction and texture extraction can be automatically processed using the silhouettes in the two views.Effectiveness of this method is shown by reconstructing real curved objects. |
