为建立使用视频荧光光谱图像技术检验不同品牌、型号复印纸的分析方法,实现对复印纸的检验和鉴别,收集了不同品牌和型号的静电复印纸20种,利用VSC6000视频光谱比较仪对其进行检验,获得样本的荧光图像,结合图像处理技术对荧光形态、荧光强度等进行可视化和量化分析。依据紫外光、强光源工作条件下纸张样品的视频荧光现象的形态学特征可对纸张进行初步鉴别;通过绘制视频荧光图像的等高线分布图可实现对纸张样品的可视化分析;计算荧光图像亮度值
L
可对纸张样品进行量化检验。研究结果表明,视频荧光光谱图像技术能够对复印纸进行准确、有效的检验,该方法适用于文件物质材料检验,为纸张的鉴别、比对和同一认定提供了一种实用方法。
In order to establish a method to examine copy paper in different brand
model by image processing techniques of video fluorescence spectroscopy (VFS) and inspect and identify copy paper in forensic science
20 kinds of copy paper in different brands and models were collected
the video spectral comparator (VSC6000) was used to analyze these papers to obtain the fluorescence image of the samples. Combining with the image processing technology
the morphology and the intensity of the fluorescence were analysised visually and quantitatively. According to the morphological features in the VFS obtained by UV-365 nm and powerful light source (400-570 nm) of the samples
the papers can be identified preliminarily. The visual analysis of the samples can be realized by drawing the contour map of video fluorescence image
and the fluorescence image brightness value
L
can be used to quantify the samples. The results prove that the image processing techniques of VFS can discriminate the copy paper precisely and effectively
which can be used to examine the document material
provide a practical method for the differentiation
comparison
identification in forensic science.
