Problems solved by technology

[0003] In the investigation of the case scene, we often find incomplete footprints, and conventional analysis methods cannot accurately determine the age information of the suspect. Therefore, a method that can accurately infer the age of the suspect based on the footprint characteristics that are easy to find is needed

Abstract

The invention provides a method for analyzing age based on equilateral triangle characteristics in footprints, which comprises the following steps of: step 1, observing the surface and the peripheralparts of the footprints, and finding out the outline of an equilateral triangle from an overall outline and fine corrugated lines; and step 2, determining the age according to the side length of the equilateral triangle, with the age corresponding to the side length of 1mm of the equilateral triangle being 1 year old, and the error range being + / -3 years old. According to the method, the age of the suspect can be accurately inferred according to the side length characteristics of the equilateral triangle of the field residual footprints and / or the field overlapped footprints.

Description

technical field [0001] The invention belongs to the technical field of footprint analysis, and in particular relates to a method for analyzing age based on equilateral triangle features in footprints. Background technique [0002] The biggest headache for technicians at the crime scene is the analysis of multiple overlapping footprints. Conventional methods must separate multiple footprints well to analyze the characteristics of a single footprint and then comprehensively infer the suspect information. This requires a deep level of business and technical skills for technicians, which very few people can achieve. [0003] In the investigation of the case scene, we often find incomplete footprints, and conventional analysis methods cannot accurately determine the age information of the suspect. Therefore, a method that can accurately infer the age of the suspect based on the easily found footprint characteristics is needed. Contents of the invention [0004] The purpose of ...
