摘　　要：【目的】犯罪分子作案后丢弃作案鞋子、鞋的种类不断增多以及人员流动频繁等因素是制约足迹在案件侦破中发挥作用的主要原因,解决足迹检验鉴定中“同脚不同鞋”难题迫在眉睫。【方法】利用压力测试纸提取足底压力分布,通过形态学分析提取特征,再将检材和样本进行聚类和主成分分析检验。【结果】甲乙两人赤足迹压力图、皮鞋足迹压力图在软件中能够很好分类,测试灰尘鞋印能够落入预先设定分区内。【结论】这种方法能够很好地判别平面灰尘鞋印是否为嫌疑足底所遗留,实现“同脚不同鞋”足迹的检验鉴定。[Objective]Factors such as the shoes discarded by criminals after a crime,the increasing types of shoes and frequent turnover of people are the main reasons that restrict the footprint to play a role in case detection.It is urgent to solve the problem of“different shoes with the same foot”in footprint inspection and identification.[Methods]The plantar pressure distribution was extracted by using the pressure test paper,and the features were extracted by morphological analysis,and then the samples were tested by clustering and principal component analysis.[Results]A and B two people and shoe footprint pressure charts can be well classified in the software,and the test dust and shoe prints can fall into the Preset partition.[Conclusion]This method can well determine whether the flat dust shoe print is left by the suspected sole,and realize the inspection and identification of the footprints of“different shoes on the same foot”.
