摘　　要：通过对平面成趟足迹进行分析和计算可以推断足迹所有者的一些诸如步长、年龄和身高等重要的特征信息。然而该类分析检验方法在人工实现过程容易出错、后期信息管理复杂且效率较低。针对以上问题,设计开发了一种成趟足迹分析检验系统,系统基于LabVIEW平台进行开发,可实现图像采集、步幅特征提取、步幅特征比对和信息管理等功能。实际的分析结果表明,系统的精度和效率均可有效满足刑侦勘探现场的要求。Through analyzing and calculating the plane footprint, we can get some important feature information such as step size, age and height, etc. However this way is difficult to apply to practice without any errors in the process of artificial implementation, information management is more complicated and messy in the later and the efficiency is very low. To solve above problems, this paper designs and develops a cluster - footprint analysis testing system. This system is based on the Lab- VIEW platform, which can realize image acquisition, stride characteristics extraction and information management and other functions. Practical analysis results show that this system can effective achieve these functions,working accuracy and effi-ciency can meet requirements of criminal investigation process.
