Computer network video monitoring to realize remote management of engineering projects
At present, the number of projects in China ranks first in the world, but there is still a big gap between the level of project management and the level of information application in developed countries. In recent years, more and more enterprises have begun to attach great importance to and actively explore innovative ways to realize off-site and off-site project management. The Ministry of Construction and several provincial and municipal construction authorities issued a document to promote the installation and deployment of remote video monitoring systems in major key projects, so as to realize real-time understanding of the construction site process, real-time monitoring of safety quality, improve the work efficiency of safety project management, feed back the construction situation of remote construction site to the project management department in real time, monitor the implementation of safety production measures at the construction site in real time, and monitor the safety factors of the construction work surface, such as grid, construction elevator, small and medium-sized construction machinery, safety net, external scaffolding, temporary. , effectively monitor and eliminate construction safety hazards.
The following is my paper on computer video surveillance, I hope it will help you!
Discussion on related problems of computer intelligent video monitoring system
Computer intelligent video monitoring system combines video processing technology, computer technology and network technology, which greatly improves the efficiency of video monitoring, so it is widely used in many production fields and has made outstanding contributions to the development of various industries. Therefore, the research on computer intelligent video surveillance system has been paid more and more attention by experts in the industry. After years of research, we have achieved fruitful research results and promoted the development of computer intelligent video surveillance system in China to a certain extent.
1 Computer Intelligent Video Surveillance System Technology
Computer intelligent video monitoring system has applied many technologies, including video compression technology, moving target detection, target recognition and tracking. Next, the above technologies of intelligent video surveillance system are discussed one by one.
1. 1 digital video compression technology
Digital video compression technology is the basis to ensure the normal work of intelligent video surveillance system, because the process of intelligent video surveillance system involves uploading, searching and downloading video information, and these links need to transmit a lot of video information. If digital video compression technology is not used for processing, on the one hand, the obtained video information will occupy a lot of storage space, on the other hand, it will seriously affect the transmission efficiency of video information. For example, if the image information of gif352*288 and 4: 2: 2 is transmitted at the speed of 25 frames per second, the amount of information to be transmitted per second is 38mb, which will consume a lot of network resources. Therefore, no matter from which aspect, the normal work of computer intelligent video surveillance needs the support of digital video compression technology.
1.2 moving object detection technology
Moving target detection technology is mainly used to monitor things or people with abnormal behavior, so as to judge possible emergencies or potential dangers. Usually, the abnormality of things or people is more or less expressed in the form of movement, and the computer intelligent video monitoring system achieves the purpose of monitoring by monitoring the movement form of things or people. In addition, when analyzing the video information collected by the intelligent video surveillance system, it is necessary to extract the changing area of the moving target from the background scene to help the staff analyze and track. However, the background graphics of video images are not static, but constantly changing with time. Therefore, they are easily influenced by factors such as shadows, light, environment and weather, which invisibly increases the difficulty of monitoring. In order to further improve the detection technology, optical flow, EM algorithm expansion package, time difference and poor background are commonly used to detect moving targets.
1.3 object recognition and tracking technology
The performance of computer intelligent video surveillance system is superior to the traditional video surveillance system, which can intelligently collect, identify and track images. Driven by the development of science and technology, the appearance of face recognition technology further enhances the development potential of intelligent video surveillance system.
The realization of target recognition and tracking technology mainly involves three aspects: moving target classification, moving target tracking, behavior understanding and description. Among them, the purpose of classifying the moving target is to identify the category of the moving target. Because there are many video surveillance contents, the correct classification of the moving target is helpful for the staff to quickly extract useful information, so as to accurately judge whether to track it. At present, the commonly used classification methods include underground hierarchical classification of time matrix, classification based on motion characteristics and classification based on shape data.
The so-called target tracking refers to the problem of establishing the corresponding characteristics of color change, speed, displacement and so on between continuous video surveillance image frames. At present, tracking based on features, active contours and models is the most commonly used. Behavior understanding and description refers to identifying, analyzing and describing the motion patterns of objects. In this process, hidden Markov and dynamic time warping techniques are used to match the test sequence with the existing marker behavior reference sequence. In addition, the common method to realize time-varying data matching is neural network, which can identify people's trajectories and motion patterns and identify them in radial basis function network.
Application of computer intelligent video monitoring system
The application of computer intelligent video surveillance system can be divided into insecurity and security. Among them, unsafe applications are mainly used for traffic flow control, crowd control and population statistics in meeting places, service areas and retail areas, while safe applications are mainly used for detecting vehicles, people and things. So as to discover anomalies in time and create a safe social environment. The application of computer intelligent video surveillance can not be separated from the support of various components. For example, the high-definition camera is used to collect video images, the optical transceiver is responsible for the conversion of optical signals to electrical signals, and the hard disk array is used to store the collected information.
Judging from the development of video surveillance system, it will develop in the direction of networking, intelligence and digitalization in the future, which will further improve the intelligence of video surveillance system. At present, there is still a certain gap between the development of computer intelligent video surveillance system in China and developed countries. Therefore, China needs to strengthen the research on core technologies and carry out close and friendly cooperation with developed countries to improve the research and development level of intelligent video surveillance system in China.
3 Conclusion
Computer intelligent video monitoring system plays an extremely important role in the normal production and business activities of various industries and maintaining social stability. Therefore, it is necessary to strengthen the research on related problems of computer intelligent video surveillance system, especially the research on related technologies and their applications, so as to promote the long-term and stable development of China's intelligent video surveillance industry.
