摘要
随着三维自由表面匹配技术在三维量测、变化检测和计算机视觉等领域的广泛应用,三维自由表面匹配技术得到了广泛研究。从三维自由表面的表达方式、匹配要素选取、转换方式和匹配策略等角度出发,对三维自由表面匹配技术和应用进行了分类概述。通过各种方法的综合分析和比较,指出各自的优缺点和适应范围以及研究中应注意的问题,并对匹配研究提出了相关建议。
For the requirement of many practical applications in the fields of 3D measurement, change detection and computer vision, the research in 3D free-form surface matching is very active. In this paper, the 3D free-form surface matching techniques and its applications are briefly reviewed from the perspective of representation, matching elements selected methods, transformation and matching strategy. Based on analysis and comparison, the advantages and disadvantages with its application fields of these methods are pointed out. Some proposals about the research on matching techniques are also given.
