摘　　要：足迹作为刑事案件现场最重要的痕迹之一,在现场出现率高,可用于分析作案人的人身特点及认定作案人。在案件现场出现的赤足印多为残缺足迹,特征信息量少,检验难度大,利用率较低。利用足底各部位花纹的分布规律,确定残缺赤足印的留痕部位,再利用图像拼接技术将残缺赤足印进行复原,可以获得更多的足迹特征信息,更有效地对残缺赤足印进行分析和检验。Thefootprint is high as one of the most important traces of the crime scene. It can be used to analyze the personal characteristics of the perpetrator and to identify the perpetrator. The bare footprint at the crime scene is usually incomplete, which have less information and difficulty in testing, and have lower utilization rate. We use the distribution law of the pattern of the various parts of the bare footprint to determine the location of the mark, then use the image mosaic technology to recovery the incomplete bare footprint, we can obtain more footprint feature information, and more effectively analyze and test the incomplete bare footprint.
