枪弹头痕迹自动比对方法的研究

Automatic Comparison Method for Bullets Head Traces

给出了两个枪弹头痕迹比对的方法.首先对于测量数据的平移和转动误差,提出了枪弹头痕迹的校正算法和矩阵低秩分解的去噪模型.最后基于矩阵的相似度定义和按次序比对的方法,给出了两个枪弹头痕迹比对的方法.试验仿真结果说明了所提方法的有效性与可行性.

This paper proposed the method to compare two bullets head traces. First, for translation and rotation error of measured data, the bullet head traces calibration algorithm and the matrix of low-rank decomposition denoising model are proposted. Then based on the matrix similarity definition and sequence alignment methods, the paper gives the method to compare two bullets head trace. The simulations are carried out to demonstrate the effectiveness and feasibility of the proposed method.
