摘要
首次给出了针对三维弹痕痕迹数据的比对分析方法,提出提取枪弹数据的多维特征,联合多维特征优势实现弹痕痕迹精确的比对分析技术。首先对数据做去噪等预处理后提取多维特征,然后进行由粗到细分级比对,实验结果证明了方法的有效性。
This paper presents the comparison of 3-D bullet mark data analysis scheme which is proposed for the first time,and puts forward the extraction of bullet data feature.Using the multidimensional characteristic advantage, it realizes more accurate analysis for bullet mark data.It extracts multidimensional characteristics at first,then analyzes and contrasts it from rough to fine.The experimental results show the effectiveness of the method.
