Method Of Improving Road Monitoring Efficiency Based On Multi-machine Joint Call

In recent years,with the development of China's intelligent transportation system,the video monitoring system has become one of the hot issues in this field.However,with the improvement of people's living standard,urban road traffic pressure is more and more big,the number of surveillance cameras in intelligent transportation system more and more,but the city video camera monitoring efficiency is not improved.In this paper,by changing the camera more joint call,can maximize the camera get maximum field and image information,thus improve the monitoring efficiency of urban road.In the combination of multi-camera and urban roads,by understanding the principle of spherical camera,can help determine the scope of the camera monitoring;through a variety of urban road type similar to the equivalent,we can more easily determine the number and location of the camera.In the part of the motion trajectory design of the multi-camera in the urban road,put forward the overall design scheme,including joint modulation to establish mathematical model for multiple cameras-matrix model,the approximate model in one-to-one correspondence are respectively determine the size of matrix and matrix model corresponds to the actual path coordinates calculation,the matrix model of work state,eventually determine each camera surveillance area and trajectory.In the test section of the interface,all kinds of vehicle information statistics are stored through the database.In the normal working state and key monitoring the working state of vehicle data processing can be seen,the normal monitoring of working status monitoring efficiency of 88.08%,key monitoring the working state monitoring efficiency of 90.77%.Finally,the working state data monitored in the camera key monitoring area compared with the monitored area,the results show that:the key monitoring work state can significantly improve the efficiency of the key monitoring area of monitoring,the camera key monitoring area to enhance the efficiency of monitoring is the key monitoring area monitoring efficiency to reduce cost,The cost factor is determined by the road type and the number of cameras.
