基于计算机三维视觉的物流产品防伪算法研究

Study on Logistics Product Anti-counterfeiting Algorithm Based on Computer-based 3D Vision

为了解决物流产品的防伪防串货问题,提出对于每件物流产品赋予唯一的数字身份标识,并在物流过程中利用计算机三维视觉技术,对物流产品进行防伪身份查询。根据物流防伪信息管理系统对物流产品的防伪标识要求,提出了基于自适应权值的局部匹配算法,有效地区分了防伪标识图像边缘,消除了因亮度差而对图像匹配结果造成的影响,改善计算机三维视觉的视差图,从而帮助系统准确地对物流产品的防伪标识图像进行识别。通过仿真实验表明,基于本算法的物流产品防伪防串货识管理系统,可以有效识别物流产品外包装上的数字身份标识,且在多种外部条件下没有出现误读的情况,从而验证了算法的有效性和准确性。

In this paper, in order to solve the problems of counterfeiting and selling outside of authorized boundary in the logistics service industry, we proposed an anti-counterfeiting identity inquiry system based on the computer 3D vision technology, presented the specifics of the inquiry algorithm and at the end, through a simulation study, proved the validity and accuracy of the system.
