Automated 3-D imaging speeds firearms analysis: Vision system uses off-the-shelf imagers, frame grabbers, motion controllers, and positioning systems

摘要

Microscopic striations on the surface of fired bullets and cartridge cases are routinely used to associate a bullet with a particular weapon. Such an association is possible because each weapon imprints unique striations on the surface of each bullet it fires. To determine a possible match between bullets fired from any particular weapon, an analysis of the bullet's surface must be made. Over the last decade, automated systems have been developed to perform this analysis.
