为探索判定非连笔交叉笔画先后顺序的新方法,采用超景深三维立体显微镜,通过实现超大景深的方式,对非连笔笔画交叉部位进行3D立体合成图像,从而对微观立体痕迹进行呈现,便于鉴定人员进行分析判定。通过对制作的签字笔和圆珠笔书写的交叉笔画的实验样本进行显微检验,先后顺序的检出率为70%和90%。利用超景深三维立体显微镜判定签字笔和圆珠笔书写的非连笔交叉笔画先后顺序的结果较为理想。
In order to explore a new method of determining the order of non-connected pen cross-stroke, a three-dimensional composite image of non-connected pen-stroke cross sections is realized by using super-depth-of-field three-dimensional microscope by means of realizing large depth of field. Identification staff to analyze and decide. Through the microscopic examination of the experimental samples of the cross strokes written by the pen and the ballpoint pen, the detection rates were 70% and 90% respectively. The use of super-depth of view of the three-dimensional stereo microscope pen and ballpoint pen to write the non-connected pen cross stroke sequence of results is better.
