Barefoot plane footprint computer program identification algorithm and build system model consistently is one of the key research content in the criminal investigation of image processing. According to the criminal investigation technical requirement and reference relevant technical data, have researched the model of barefoot plane footprint recognition system, have selected and definited Biological characteristics points and characteristics lines of barefoot plane footprint, have proposed the method about feature point positioning and characteristic parameters calculation, and Has been realized the computer programming of interactive Barefoot plane footprint recognition system to use Matlab language, calculated and analyzed the Morphological characteristics parameters error, had been Realized the technology solutions of interaction barefoot plane footprint recognition system. By experiment, the scheme has been fulfilled the actual requirements of criminal investigation technology, can be used as reference about barefoot plane footprint automatic identification system research and technology.%赤脚平面足迹(赤平足)计算机识别算法和系统建模一致是刑侦图像处理研究的重点内容之一,根据刑侦技术要求和相关技术资料,对赤平足识别系统建模进行了研究,对赤平足生物形态特征点/线进行了选择和定义,提出了特征点定位及特征参数计算的技术思路,并应用Matlab语言对交互式赤平足识别系统进行了编程实践,对实验所得到的形态特征参数进行了误差计算和分析,实现了赤平足交互识别系统的技术方案.经实验表明,该方案已达到刑侦技术识别和鉴定的实际要求,可作为赤平足自动识别系统研发的技术参考.
