Experimentálne verifikačné merania zamerané na posúdenie presnosti 3D dokumentácie trasologických stôp

Abstract

The submitted article presents a partial objective of the ongoing research entitled “Investigation of the Potential of 3D Technologies in Securing and Extracting 3D Footwear Impression Traces.” This objective, also addressed within a diploma thesis, consisted of a series of experimental measurements focused on acquiring 3D models of footwear impressions created with a reference substitute shoe sole, in order to maintain repeatable conditions. The article further proposes a procedure for analysing the collected data using available software tools and for evaluating the accuracy of the applied 3D methods for documenting volumetric footwear impressions. Particular attention is devoted to the application of photogrammetry in documenting these impressions and to the subsequent extraction of their volumetric parameters along the x, y, and z axes. Such data can be especially useful for more complex biomechanical assessments, for example, when estimating physical parameters such as the perpetrator’s body weight.
