Some Forensic Aspects of Ballistic Imaging
Analysis of ballistics evidence (spent cartridge casings and bullets) has been a staple of forensic criminal investigation for almost a century. Computer-assisted databases of images of ballistics evidence have been used since the mid-1980s to help search for potential matches between pieces of evidence. In this article, we draw on the 2008 National Research Council Report Ballistic Imaging to ...
متن کاملProposed “NIST Ballistics Identification System (NBIS)” Based on 3D Topography Measurements on Correlation Cells*
The National Institute of Standards and Technology (NIST) has proposed a “NIST Ballistics Identification System (NBIS)” to facilitate accurate ballistics identifications and fast evidence searches [1]. The NBIS will use three-dimensional (3D) topography measurements for ballistics identification and evidence searches. The 3D topographies will be subdivided into arrays of correlation cells in or...
متن کاملDevelopment of Ballistics Identification – From Image Comparison to Topography Measurement in Surface Metrology
Fired bullets and ejected cartridge cases have unique ballistics signatures left by the firearm. By analyzing the ballistics signatures, forensic examiners can trace these bullets and cartridge cases to the firearm used in a crime scene. Current automated ballistics identification systems are primarily based on image comparisons using optical microscopy. The correlation accuracy depends on imag...
متن کاملTopography measurements and applications in ballistics and tool mark identifications*
The application of surface topography measurement methods to the field of firearm and toolmark analysis is fairly new. The field has been boosted by the development of a number of competing optical methods, which has improved the speed and accuracy of surface topography acquisitions. We describe here some of these measurement methods as well as several analytical methods for assessing similarit...
متن کاملBallistics Image Processing and Analysis for Firearm Identification
The identification of firearms from forensic ballistics specimens is an exacting and intensive activity performed by specialists with extensive experience. The introduction of imaging technology to assist the identification process of firearms has enhanced the ability of forensic ballisticians to conduct analyses of these specimens for identification. The positive identification of ballistics s...
