To obtain three-dimensional images of the surface of the object, a 3D scanner Stereoscan 5MP (Breuckmann GmbH, Germany) was used, and for subsequent processing, comparison and analysis of images, specialized computer programs Optocat 2007 (Breuckmann GmbH, Germany) and GOM Inspect V8 (GOM, Germany) were used.RESULTS AND CONCLUSION: The evaluation of the obtained three-dimensional images and the three-dimensional models based on them showed high reproducibility of the method's results, which allowed us to determine a set of criteria for preserving the volume of soft tissues and the skin relief of the face part of the embalmed human body during its long-term preservation, namely, the acceptable average and maximum deviations in the geometry of the three-dimensional images and 3D-models of the face.PMID:42170931 | DOI:10.17116/sudmed20266903125
