Abstract
A computerized system and method of computerized bullet ballistic analysis is based on acquisition of depth profiles of the surface of a bullet under examination, estimation and compensation for coaxiality errors of the data acquired, and matching normalized data with reference data related to reference bullet(s) or a gun in question to determine whether the bullet under examination was fired from the gun in question. The computerized system includes a mechanism used for holding and rotating a bullet, a depth sensor measuring the depth profile of striations over part of the surface of the bullet, an analog to digital converter for receiving data from the sensor and sending digitized data to the computer where a computer program estimates and compensates the received digitized data for coaxiality errors and compares the normalized data of the bullet under examination with reference data.
