针对现场勘验中对潜指纹的无损采集和较低的检测率的问题,本文设计了一种基于偏振法的潜指纹检测方法。通过使用轻量化、小体积的便携式偏振相机在主动光源条件下获取亚克力板样本上的指纹偏振图像,分别获取指纹样本的线偏振度、线偏振角、全色图像信息,在此基础上建立目标图像的偏振HSV模型图像信息并对全色可见光图像与偏振度图像进行基于小波的图像融合处理,得到了较好的潜指纹匹配效果。 |

Aiming at the problem of non-destructive collection of latent fingerprints and low detection rate in the field investigation,this paper designs a latent fingerprint detection method based on polarization method.By using a lightweight,small-volume portable polarized camera to acquire the fingerprint polarization image on the acrylic plate sample under the active light source condition,the linear polarization degree, the linear polarization angle,and the full-color image information of the fingerprint sample are respectively obtained,and the target is established on the basis of this.The image information of the polarized HSV model of the image and the wavelet-based image fusion processing of the full-color visible light image and the polarization image are obtained,and a better latent fingerprint matching effect is obtained. |
