Research And Realization Of Remote Digital Video Monitoring And Image Recognition System

Firstly,the thesis analyzes the develop,application and research state of the remote digital video monitoring system and the technologies of image processing and pattern recognition.Then the design and realization procedure of the remote digital video monitoring and image recognition system are introduced explicitly. The system can monitor the power company's remote communication control room and recognize the change of warning light on the communication equipment.The network structure of this system adopts the advanced web technology.The Visual C++,Java script,HTML,SQL server 7.0 and ASP , ActiveX are used in the system software developing. The system adds the image recognition function on warning signal lights except the traditional video monitoring,remote control and collecting alert signals function etc.The methods for alert signal recognition include gray histogram arithmetic,pattern matching method and HSI system.The gray histogram arithmetic is the best method for this system.A tool to analyze the object based on color character is designed.The threshold value for image recognition can be decided by many experiment and the results statistic.The results of many experiment in defferent conditions, the image recognition accuracy rate has reached 100%.The results of testing for the system's all performances and indexes have show that one server can monitor and recognise four video signal inputs. The number of areas that can be recognised are 2 to 16. Meanwhile the server's CPU, network, memory, pysicdisk can work normally.Finally, the thesis predicts the prospect of the remote digital video monitoring and image recognition system in application and technology aspect.
