FIXATION AND EXAMINATION OF VOLUMETRIC TRACKS OF FOOTWEAR USING 3D SCANNING TECHNOLOGIES

The article is devoted to demonstrating the possibilities of using 3D scanning technologies capture and study volumetric footprints. author notes that traditional methods visual fixation such reflections (description, measurement, photography) are not informative enough, main method object (making plaster other molds) associated with risk significant damage fixed trace. At same time, use contactless scanners allows you quickly, efficiently, non-invasively create detailed digital models experimentally tested shoe footprint in terms inspection scene (at place its detection), potential trace-forming separate (in laboratory), as well a laser Artec Leo Space Spider Studio 16 software. Possibilities software compare forensically objects demonstrated. author’s experiments showed accuracy up 0.1 mm appropriate software, it possible scan examine prints medium large tread pattern elements, 0.05 more – traces left by shoes complex patterns sole protector. obtained this way accurate detailed, accurately convey size, shape, color scanned objects, can be used for comparison their demonstration (for example, court). level detail comparative studies corresponding traceorming on models. Methods similar those described effectively types objects: tire treads parts vehicles, breakage tools, bullet holes, etc. Key words: scanning, scanner, fixation, foot traces, research.
