BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a weapon management system using a cop's black-box, and a method and apparatus for the cop's black-box, and more particularly, to a weapon management system using a cop's black-box which collects environment information by sensing an aiming movement of a user to a subject according to use of a weapon from a first cop's black-box, and receives, from a plurality of second cop's black-boxes located within a preset radial distance from the user, external environment information based on the aiming movement of the user, a cop's black-box, and a method therefor.
2. Description of the Related Art
Conventionally, only limited possession and use of weapons have been allowed in this country and thus accidents related to weapons have been rare. However, as possession and use of limited weapons such as hunting rifles and air guns for various purposes including hunting, scaring birds away, and sports activities were allowed. In particular, as accidents related to weapons have recently occurred home and abroad, there is a need for a systematic method for tracking and controlling use of weapons.
In particular, attention has been drawn to legal use of weapons among police officers, and demands for management or monitoring of use of weapons have drastically increased. Thereby, effort have been put into collecting environment information according to use of weapons to determine legality of use of weapons.
In this regard, in conventional weapon-related technology, environment information about surroundings according to firing is collected using a camera operated by firing of a weapon of a police officer, or location information about police officers is collected. Then, the collected information is transmitted to, for example, the police station. According to such conventional technology, environment information provided after use (firing) of the weapon of a police officer is collected to determine legality of use of the weapon. According, the conventional technology has a limit in performing real-time monitoring by determining the overall situation in relation to use of the weapon.
Further, according to the conventional technology, as the environment information according to firing of a weapon is collected using a camera included in a police car, only information about the environment near the police car can be collected.
