摘要
针对目前图像及3D扫描方法难以通过痕迹有效快速匹配剪切工具的弊端,设计并实现了一套警用线条痕迹激光检测系统。该系统由运动控制子系统、激光检测子系统和显微摄像子系统三部分组成。通过夹持线缆断头,首先控制单点激光位移传感器拾取剪切类线性痕迹的表面特征信号,随后利用痕迹特征相似重合度匹配算法,将痕迹激光检测数据与数据库进行比对,最终实现对应剪切工具的快速匹配。
In view of the disadvantages that the current image and 3D scanning method is difficult to fast and effectively match the cutting tool through the traces, design and implement a set of police line traces laser detection system. The system is composed of three parts： the motion control subsystem, the laser detection subsystem and the micro imaging subsystem. By holding the cable breakage, firstly,control the surface characteristic signal of that single point laser displacement sensor picks up the linear shear traces, then using the similar coincidence degree matching algorithm of the traces characteristics, compare the trace laser detection data with the database, and finally realize the fast matching the corresponding cutting tool.
