Research On Smart Firearms Technology Based On Fingerprint Recognition

As the technology of intelligence began to penetrate into all fields,firearms began to move towards the road of intelligent recognition.By consulting the literature and analyzing the research status of intelligent identification guns at home and abroad,biometric technology,one key technology in the intelligentization of firearms is analyzed in detail.In this paper,the fingerprint recognition technology is used to realize the intelligentization of firearms.The design of gun structure and the design and selection of electronic devices for an intelligent firearm are carried out.In the structure of guns,a sequential preloading technology of three rounds is adopted.The internal and external ballistics of the gun model are analyzed and calculated,and the temperature field is analyzed by the results of the interior ballistics calculation,which provides a reference for the selection of electronic devices.According to the demands of some intelligent firearms for biological identification,wireless communication and electronic control,the paper selects the corresponding electronic components which can meet the functional requirements.On the basis of the temperature field caused during the operation process of firearms,and with the operation temperature of electronic components as the main reference element,the selections of various electronic models are conducted.The related control programs are written to meet the needs of the work.The improvement studies of the algorithms of fingerprint image recognition technologies of fingerprint image preprocessing,feature recognition,the deletion of pseudo feature points and the fingerprint image comparison were carried out,so that improve the adaptability of recognition system to dry and wet fingerprints was improved,and the intelligent recognition for the normal use firearms under complex environment was satisfied.Finally,according to the electronic selection and research,the identification system of an intelligent gun is developed.According to the indexes,the corresponding test method is put forward.The rationality of the research plan is verified by experimental research.The research results provide a good theoretical and experimental basis for the research of the intelligent recognition technology of a firearm.
