基于多尺度分析的三维曲线匹配技术研究
THREE DIMENSIONAL CURVES MATCHING BASED ON MULTISCALE ANALYSIS
【摘要】 从提取三维物体碎片轮廓曲线出发,提出一种基于多尺度分析的三维曲线匹配技术。轮廓曲线经多尺度平滑后,计算曲线的特征矢量,通过比较特征矢量以判断轮廓曲线的相似性,实现三维曲线匹配。实验表明提出的算法具有准确性、鲁棒性和容错性。
【Abstract】 On the basis of contour extraction of 3D fragments,a novel 3D curves matching method based on multiscale is presented.The feature vector of contour which smoothed by wavelet transform are calculated.Similarity between two contour curves is determined by comparing feature vectors of two contour curves.Contour curves matching are realized.Experimental results show that this approach is robust,fault tolerant and effectiveness in matching and can get accurate matching.
