    Experimentálne verifikačné merania zamerané na posúdenie presnosti 3D dokumentácie trasologických stôp
    (University of Žilina, 2025) Adamová, Veronika; Kolla, Eduard; Szabo, Lukáš
    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.

    Metodika tvorby a zaisťovania chodníčka bipedálnej ľudskej lokomócie
    (University of Žilina, 2023) Šimčeková, Damiána; Adamová, Veronika
    A part of specific methods in criminalistics applied in practice is tracology, used for obtaining and documenting evidence from crime scenes. Tracology deals with various types of evidence, including footprints, tire tracks, and footwear. We must not overlook traces left by lips, teeth, or other parts of the human body. This work describes the creation of a human locomotion pathway on a surface. The pathway is generated by the coloured soles of an individual walking to collect documents. In a real-life scenario, we can envision a situation where a perpetrator steps in the victim's blood and then walks across a carpet, leaving traces in the process. After leaving these traces, a forensic expert can secure and extract necessary information from them. This information may include parameters such as the length of a single step or a pair of steps, which can subsequently be used in mathematical models to estimate the body height of the individual. The presented article focuses on the approach to the field of tracology, which represents a distinct scientific discipline within the realm of criminalistics. Specifically, in this article, our emphasis is on presenting the measurement and data collection process in connection with the resolution of an institutional grant project.
