ИДЕНТИФИКАЦИЯ ПО СЛЕДАМ НА ПУЛЯХ С ИСПОЛЬЗОВАНИЕМ ИЗМЕРЕНИЯ ТОПОГРАФИИ МИКРОНЕОДНОРОДНОСТЕЙ И КОРРЕЛЯЦИИ. ОБЪЕДИНЕНИЕ МИКРОСКОПИИ И СТАТИСТИЧЕСКИХ МЕТОДОВ

Abstract

Current firearm identification is based on image comparisons using optical comparison microscopes. The ability to produce an accurate identification depends on image quality which is largely affected by lighting conditions. Because ballistic signatures are geometrical micro-topographies by nature, the main objective is to demonstrate the usefulness of surface topography measurement techniques for firearm identification. Additionally, an objective mathematically based acquisition and comparison method would help demonstrate the foundation of the science of firearm and toolmark identification.
