激光定位靶/射击场自动报靶器系统在刑侦技术与司法鉴定中的应用介绍
The Laser Positioning Target/Shooting Range Automatic Target Reporting System is a specialized intelligent shooting training and bullet mark identification auxiliary equipment in the fields of criminal investigation technology and forensic identification. Based on laser sensor composite positioning technology, it captures the coordinates of bullet impact points in a non-contact manner with high precision of ≤1mm, integrating core functions such as intelligent target reporting, score management and multi-scenario adaptation. It not only standardizes the shooting training of criminal investigation personnel, but also provides accurate and traceable technical support for bullet mark identification, injury mechanism analysis and crime process reconstruction of gun-related cases, solving the pain points of low accuracy and inability to quantify bullet mark parameters of traditional target reporting.
The core performance of the system is accurately adapted to the needs of criminal investigation and forensic identification: high-precision laser positioning is not affected by the material and damage of the target plate, without missing or false reports, and can accurately capture the coordinates of bullet impact points, providing quantitative data for bullet mark comparison and inference of shooting distance and angle; it is compatible with multiple gun types, bullet types and target types, and can simulate shooting scenarios of different gun types and bullet types in gun-related cases to restore real crime conditions; the personal shooting file and score traceability function can retain the training bullet mark data of criminal investigation personnel, and provide reference for comparing the shooting habits of involved personnel and locking the shooter; the hidden-display target control and multi-distance adaptation can simulate actual combat shooting scenarios and assist in analyzing the injury mechanism.
Combined with criminal investigation practice and forensic identification cases, its application value is prominent: Case 1, in a gun-related intentional injury case, the police used the system to simulate the 25-meter shooting distance and pistol type at the crime scene. Through high-precision bullet impact point positioning, they restored the bullet flight trajectory and shooting angle, compared the bullet marks extracted from the scene with the system-simulated bullet mark parameters, and provided key basis for the analysis of injury mechanism and the inference of the shooter's posture in forensic identification. Case 2, in gun performance identification, the system is compatible with the involved rifle and metal bullets, accurately records the distribution of bullet impact points and shooting precision, quantitatively analyzes whether there are defects in gun performance, provides scientific data support for determining "whether the gun has injury-causing ability" in forensic identification, and assists in investigating the ownership of the involved gun.
In summary, the system is suitable for scenarios such as criminal investigation shooting training, bullet mark identification of gun-related cases, gun performance evaluation and crime process reconstruction. It can realize accurate positioning of bullet impact points and traceability of shooting data, which not only improves the actual shooting ability of criminal investigation personnel, but also standardizes the forensic identification process of gun-related cases, providing objective and quantitative basis for identification conclusions. It is an indispensable professional intelligent equipment in the fields of criminal investigation technology and forensic identification.
