Application Scheme Of Video Surveillance System Based On Multiple Target Types

Video monitoring,as a comprehensive application of computer network technology,communication technology,digital video compression coding technology and other technical fields,has been widely used in security and defense fields of various industries due to its features of richinformation,intuitive content and convenient deployment.Based on the higher awareness of security,people's need for security system is also increasing.Video monitoring system is an important part of security system,and its function is developing towards intelligence,diversification and integration.This thesis to realize video monitoring system is mainly used to store and plot monitoring,the integration of the human body,human face model and the behavior of the three algorithms,realized to the human body,human face attribute extraction,the establishment of the human body,human face model,and real-time blacklist alarm and behavior alarm,in addition,also provides users with an attempt to search by picture,identification and other applications.The human algorithm based on foreground detection and object recognition method is used for detection,analysis and modeling of human body in video,the facial algorithm based on feature method is used for detection,analysis and modeling of human face in pictures,and the behavioral algorithm based on human body detection usually adopts background separation(background subtraction)technology to detect human behavior in video.In this paper,through the analysis module unified scheduling of these three algorithms,to achieve a video stream of human body,face,behavior analysis,expand the video monitoring system intelligent.The derivative functions such as image search and identification generated based on the model are essentially the application of model comparison.By model comparison of 1V1 or 1VN,the similarity between 2 or more is generated,and the required comparison results are obtained through the set similarity threshold.The actual alarm alert function based on the behavior alarm can release the observer from the long-term monitoring and observation state and realize the intelligent monitoring of the defined dangerous behaviors.Video monitoring system takes intelligent analysis server as the core,integrates front-end camera,image storage server,big data and other devices,and creates an intelligent platform integrating data collection,data analysis,data storage and data application.
