Ballistics imaging-latest developments

摘要

This paper outlines the latest developments concerning a forensic imaging system that uses a CCTV camera in a line-scan mode for the inspection of bullet specimens placed on a rotating platform. Specifically, line-scan images obtained from the cylindrical sides of fired rounds including both projectiles and cartridge cases plus firing pin marks are discussed. Ultimately, it is anticipated that this research will lead to the development of a forensic imaging application from which a data base can be built to automatically match different bullet specimens in much the same way as a fingerprint data base is operated.
