The Design And Implementation Of Police Image Detection System

Image detection is a professional term for video detection used by the public security department,which is a technical approach used to find the suspect through detection of video and images.The general procedure is that through technical judgment of case,the public security department checks the video surveillance that could contains the image of suspect to find the suspect's trace.With the economic development,the state has made major efforts to build safe city,there are more and more video surveillance devices with expanding coverage,the images are getting clearer,and this is the necessary condition for the development of image detection technology.Based on the video intelligent analysis technology and the image detection technology of public security department,by combining the service requirement of public security criminal investigation work,the image detection system has comprehensively considered other service condition of image detection system,and by following uniform software development process,efforts are made to discuss the design and realization of main service functions of image detection system.This paper mainly consists of the following content:(1)Complete the requirement investigation and analysis of police image detection system,and organize the functional,nonfunctional and interface requirements.Investigate and analyze the existing service system of public security network,as well as the image detection,analysis and judgment process of Criminal Police Unit.(2)Based on the mainstream system design concept for technical and information architecture,provide the general design of system.By adopting layered architecture to realize system design and the mainstream Internet technology to design the system framework,with the C/S system as the system architecture and J2 EE as the backstage processing core,based on the RESTful external interface unified protocol,conduct allocation and design of system module.(3)Provide specific design,test and operation information of core system functional modules,including the system functional design,main interface and function design,sequence diagram,test cases and operation effects.The design approach and specific realization described in this paper have been applied and verified in actual business environment,which has achieved expected results.It has provided strong support to improving the investigation level and efficiency for criminal cases.
