摘要
本文首次针对三维弹痕数据的三维拓扑结构特性的描述问题,提出基于3D-Zernike的三维特征提取方法。充分利用3D-Zernike描述子的平移,尺度,旋转不变性,信息表达的高效性,面向真实三维弹痕数据进行分析和比较。实验验证了该特征对于三维弹痕数据描述的有效性,3D-Zernike描述子对弹痕的次棱数据的描述表现出很好的同一性和差异性。
This paper proposes a three-dimensional feature extraction method based on 3D-Zernike descriptors for topological description to three-dimensional structural properties of bullet data at first time. Making full use of 3D-Zernike descriptor translation, scaling, rotation invariance, efficiency of expression of information true 3D bullet data are analyzed and compared. Experiments verifies the validity on the characteristics of three-dimensional bullet data description. 3D- Zernike descriptors on the description of the bullet secondary edge data showes good identity and differen tiation.
