摘　　要：目的探索利用计算机自动比对技术对彩色激光打印机跟踪暗码进行识别与比对,通过跟踪暗码点阵形态自动获取彩色激光打印机的相关信息。方法利用VSC8000文检仪和Photoshop CS6图像处理软件对常见不同品牌、不同型号的彩色激光打印机跟踪暗码进行显现、比较及分析,归纳出跟踪暗码的点阵结构规律并建立数据库,最后通过编写比对程序对彩色激光打印机的信息进行自动识别。结果该比对程序可以实现对不同品牌、不同型号的彩色激光打印机跟踪暗码进行自动比对。结论利用计算机自动比对技术对彩色激光打印机跟踪暗码进行识别与比对具有可行性,但在鉴定实践中还存在一定局限性,需要进一步研究和完善。Purpose The identification and comparison for tracking code of color laser printer were explored by using computer automatic alignment technique,and the related information about the color laser printer was automatically obtained by tracking code lattice form.Method By using Video Spectral Comparator(VSC8000)and Photoshop CS6 image processing software,tracking codes of color laser printers of different brands,different models were revealed,compared and analyzed.The lattice structure of tracking code rule was summarized,and a database was established.Finally,a comparison program was written to automatically identify the information of color laser printer.Conclusion It is feasible to use computer automatic alignment technique for identification and comparison of color laser printer tracking code.However,there are some limitations in the appraisal practice,which need further investigation and improvement.
