NIJ and Intelligent Automation, Inc. - Demonstrating Objectivity in Ballistic Identification: Statistical Validation Using Topographical Imagery

NCJ Number
Date Published
May 2015
2 pages

This fact sheet reports on the testing method and outcome of a first-of-its-kind ballistic analysis system developed by Intelligent Automation, Inc. (IAI) with funding from the National Institute of Justice.


The statistical analysis of the results of firing, retrieving, and comparing 2,800 fired bullets with this system demonstrated that the premise of firearms identification could be validated in a quantitative manner. This innovative system is topography-based (3D) and is automated. The incorporation of 3D data (topographic imagery) is an innovative advancement that is superior to the existing photographic approach. This patented technology has been integrated into Forensic Technology's IBIS TRAX-HD3D product in order to capture high-resolution images and topographic information from fired bullets at the nanometer level. Its 3D sensor technology provides optimal performance for the specific characteristics of bullet markings. The topographical information has helped police and military organizations around the world gain actionable information from firearms and their fired ammunition components.
