| 摘 要： | 研制了一种新型的枪弹痕迹计算机自动识别系统，该系统采用了一种新型的微恒力位移传感器，该传感器具有测量力小且恒定的特点，因此，可以实现对弹头痕迹的无损测量，采用一种改进的小波分析方法提取出反映反射弹头枪支稳定痕迹特征的信号，消除了边界失真，并可在不同尺度上对弹头发射痕迹进行分析，同时提出一种多尺度相关分析方法，可以综合利用各个频率段上信息，将其用于枪弹痕迹的识别中取得很高的识别率。

| Abstract: | A novel automatic recognition system for bullet marks is developed. A new micro constant force displacement sensor with micro and constant measurement force is introduced. It can realize the measurement of bullet marks without damage on the surface of sample bullets. Based on the improved wavelet analysis technology, the signals that reflect the stable characters of the guns that fire the sample bullets are extracted exactly without boundary errors and can be analyzed on multi scalar. A novel multi scalar correlation analysis technology that can use the information of multiple frequent segments is adopted and obtained at a very high identification rate. |
