Embodiment 1
[0042] Embodiment 1 of the present invention discloses a method for establishing a three-dimensional model database of firearms and spare parts, such as figure 1 As shown, the method includes the following steps:
[0043] Step 101, collecting attribute information, planar image information and three-dimensional structural models of firearms and spare parts;
[0044] Step 102, storing the attribute information, the planar image information and the three-dimensional structure model in the database to form a gun and spare parts database;
[0045] Step 103: When receiving a retrieval request including retrieval data, perform matching in the database of firearms and spare parts based on the retrieval data, and feed back the matching results.
[0046]In a specific embodiment, the attribute information of the firearm includes: serial number, quality, size, caliber, name, structure, country of manufacture, manufacturer, model, year of production, surface identification, and material ...
Embodiment 2
[0072] Embodiment 2 of the present invention also discloses a three-dimensional model database system for firearms and spare parts, such as Figure 5 shown, including:
[0073] The collection module 201 is used to collect attribute information, planar image information and three-dimensional structural models of firearms and spare parts;
[0074] The database module 202 is used to store the attribute information, the planar image information and the three-dimensional structure model in the database to form a gun and spare parts database;

Abstract
The invention provides a method for establishing a three-dimensional model database of guns and spare parts and a databasesystem. The method comprises the following steps of acquiring attribute information, plane image information and a three-dimensional structure model of the guns and the spare parts; storing the attribute information, the plane image information and the three-dimensional structure model in a database to form a gun and spare part database; and when a retrieval request containing retrieval data is received, matching being performed in the gun and spare part database based onthe retrieval data, and a result obtained through matching being fed back. According to the method, three-dimensional reconstruction of guns and spare parts thereof being realized; establishing a database of guns and spare parts thereof, wherein various kinds of information such as the attribute information, the plane image information and a three-dimensional structure model are covered in the database. On the aspect of a database retrieval function, retrieval methods are enriched, three methods can be provided for retrieval selection, and accuracy and reliability of the retrieval function areimproved.
Description
technical field [0001] The invention relates to the field of gun data management, in particular to a method for establishing a three-dimensional model database of guns and spare parts and a database system. Background technique [0002] Guns have powerful power. Every year, my country’s customs seizes a large number of illegally smuggled guns and ammunition. In order to evade law enforcement and supervision, criminals often use various methods to dismantle guns, break them into parts or refit them and smuggle them into the country. These guns And parts are not easy to identify, such as identifying whether a part is a part of a gun? If yes, which part of which model of firearm? Our country does not yet have a complete database of guns and their spare parts, which will require a lot of manpower and material resources for screening and verification, and bring great difficulties to the detection of smuggling cases. In today's rapidly developing digital age, it has become a popu...
