三维曲面体的标记与匹配,是计算机视觉研究领域中一项相当有用但又是非常困难的技术。本文讨论了一种曲面体标记的新方法。通过引入线段的一些新的标记类型,圆满地解决了利用 Huffman 标记技术描述曲面体时,可能出现的不一致性。根据以上的标记结果,本文还给出了一匹配曲面体线图的新方法。在匹配过程中,我们注重的不是图象的二维特征,而是其对应的物体的三维特征,因而对物体的旋转、遮挡、尺度变化及远视失真等极不敏感。实验结果表明本算法是相当令人满意的。
The labeling and matching of 3D curved surfaces are a very useful but very difficult technique in the field of computer vision. This article discusses a new method for surface marking. By introducing some new mark types of line segments, the inconsistencies that may occur when using the Huffman mark technique to describe surface bodies are satisfactorily solved. Based on the above results, a new method of matching the body contour map is also given. In the process of matching, we focus not on the two-dimensional characteristics of the image, but on the three-dimensional characteristics of the corresponding objects. Therefore, we are extremely insensitive to the rotation, occlusion, scale changes and hyperopia distortion of objects. Experimental results show that the algorithm is quite satisfactory.
