Dedicated to Producing Results in a Short Time

The major task of the ARSENAL system is to use your ballistic files in the most efficient way in order to make a thorough examination and to obtain the most reliable results in a shortest possible time. It is obvious, that the core of the solution consists in automation and computerization of the identification operations, and this task cannot be solved without using state-of-the-art technologies. The ARSENAL system possesses all necessary tools for that. ARSENAL is a modern powerful computer system capable to automate the whole procedure of examination of bullets, cartridge cases and their fragments: from data entry and creation of electronic database, matching and split-screen verification to results of comparisons conducted.

ARSENAL ABIS is dedicated to

Creating automated databases for rifled firearms booked in law-enforcement agencies Creating automated databases for bullets and cartridge cases captured at crime scenes Basing and filing the records of evolvents of bullets' leading surface and marks on cartridge cases

  • Computerizing searches against databases
  • Comparing bullets or cartridge cases side-by-side
  • Automating the documenting of examination results
  • Interregional data exchange
  • Functionality of ARSENAL ABIS

The ARSENAL ABIS automates the following tasks

Scanning entire bullet and cartridge case sides, cartridge case head, marks captured from shell fragments and deformed bullets

Captures cartridge case head images using lighting in sectors. This method of scanning makes so me characteristic marks (firing pin impressions, breech face marks, ejector marks) to look more legible than they are when being captured by ring lighting

Automatically determining location of driven edge and leading edge impressions in an evolvent record

Interactively locating unique impressions (striations) on a bullet and cartridge case side Automatically determining significant marks location on a cartridge case head with the possibility of human-aided corrections

Encoding significant marks in a cartridge case head record

  • Firing pin impression
  • Breech face marking on a primer
  • Ejector mark
  • Encoding unique impressions on the surface of a bullet
  • Encoding significant marks on the side surface of a cartridge case
  • Extractor hook mark
  • Slide hole mark
  • Magazine edge mark at loading
  • Magazine edge mark at ejecting
  • Chamber wall mark
  • Barrel rear part edge mark
  • Cartridge insertion mark
  • Breech lower edge mark
  • Automatically searching against database files
  • Providing candidate lists (recommended lists of possible matches) as determined by the matching process
  • Side-be-side visual comparison of images using methods of correlation, alignment and overlay
  • Storing records in database utilizing the WSQ image compression method
  • Viewing a pseudo-3D image and cross section of a cartridge case head to visually reveal details of a firing pin shape
  • Originating graphic illustrations of high quality
  • Integration into any network
  • Remote input of images and remote access to Central Database
  • Distributing database access rights and protecting data stored in database and transmitting over communication channels
  • Import/export image in TIFF-format via communication lines supporting IP-connection Search reliability by striations on bullets is provided at 90%-level, the finding accuracy being 85%. Search reliability by marks on cartridge cases is provided at 90%-level, the finding accuracy being 80%. It is achieved through the implementation of state-of-the-art scientific and engineering solutions such as:
  • Mathematical algorithm of image encoding and identification, the principle of which was tested out in long-term practice of the Automated Fingerprint Identification System PAPILLON
  • Automated input device - Ballistic Scanner - that makes it possible to obtain images of high quality

The Ballistic Scanner is a multipurpose device on the basis of a linear CCD-sensor containing 5 thousand elements. It enables the scanning of bullets (entire evolvent of a bullet side, marks on shell fragments), cartridge cases (including a side face) and objects to 20 mm in size with a 4-mic resolution. The side scanning procedure consists in consecutive digital image recording in computer memory (the lighting being slanting and the object rotating around its vertical axis). A cartridge case head is scanned at two types of lighting: circular diffused and circular mirror. The object being scanned is immovable at that. In the similar way is executed the scanning of marks on heavily deformed (more than 3 mm) bullets and shell fragments at slanting lighting.
