What Are the Difficulties of Video Structured Application in the Security Industry? How to Achieve Self Breakthrough?

Of course, at present, its most mainstream applications are concentrated in the public security industry, because they encounter some difficulties and problems in business practice:1. There is a lack of standardized generation methods of video information intelligence, and then there is a lack of a new police work mode of using video information intelligence to guide investigation and solve cases. Now the application of video surveillance has been integrated into the daily case handling work of the police, but it is still a manual way to browse and check, which is time-consuming and laborious.2. The cross domain and cross police sharing of video information and the interconnection with other information systems are prominent. The language of cross system is not unified, resulting in information becoming isolated islands, which limits the construction and application of big intelligence and big information systems.

3. For the problem of storage and transmission, due to the limitation of saving a lot of storage space and transmission bandwidth, we have to compress a lot of video data, which not only causes the problem of image blur, but also the way of fixed compression ratio is not flexible enough, so we have to occupy a lot of storage space and transmission bandwidth.4. For the problem of efficient computing, video surveillance requires multi-function and real-time computing, and the particularity of video data increases the computing cost. It is necessary to build a unified Video Computing Theory and framework for video surveillance.5. There is a lack of unified standards and norms in the application of video information and intelligence policing. The root of all these problems lies in the lack of understanding of video content, and there is no efficient and standardized method of video data exchange and video intelligence extraction. To solve these practical problems, we need to focus on video structured description and the construction of a new video monitoring system based on this technology.

To meet the challenge of in-depth application of video surveillance system, its core and bottleneck is to solve the transformation from video surveillance data to video information and video intelligence by studying video structured description technology, so as to realize the innovation of police work mode.It can be seen that in the era of big data, the solution to the problems of how to efficiently extract video information and how to carry out standard data exchange, interoperability and semantic interoperability with other information systems is video structuring technology. Transform the traditional video surveillance system with video structured technology to form a new generation of video surveillance system, that is, the intelligent, semantic and intelligent video surveillance system we often say.This means that video structured technology represents the future of industry monitoring technology.

Application and Prospect Analysis of video structuring technology

Since it is the future of security technology, how do we apply it and what are the prospects of video structuring technology? Video structuring is a technology of video content information extraction. According to the semantic relationship, it organizes the video content into text information that can be understood by computers and people by means of temporal and spatial segmentation, feature extraction, object recognition and so on. From the process of data processing, video structured description technology can transform surveillance video into information understandable by people and machines, and further transform it into intelligence used by public security practice, so as to realize the transformation of video data into information and intelligence.

In order to realize the transformation from video data to video intelligence, it is suggested to adopt the following three measures to break through the deep problems restricting the construction and application of video surveillance.1 Study key technologies and break through application problems. On the basis of studying the video application law of public security business departments, this paper establishes a structured description model of surveillance video, and overcomes a number of key technologies related to video segmentation, content extraction and content description. The research involves the key applications of description database management technology, image and video semantic retrieval technology and corresponding data service technology.2 Strengthen top-level design and build a standard system at the same time. Standardization is the basis of information sharing. Through the research on the characteristics and application mode of video structured technology, establish the standard system model of video structured description, formulate the standardization system covering technology implementation and application system, and formulate relevant standards step by step to standardize technology research and equipment development, and guide all aspects of system construction, operation and evaluation, It lays a good foundation for the comprehensive development of video information intelligence application from the source.

3 Carry out the construction of video information information system platform step by step, and gradually promote the integration and application of public security information resources. Carry out research on the application service mode of video structured description data, formulate the system and solution of video structured application, and build an application demonstration system for one or two typical application environments. Through the construction and operation of the system, verify the solution of the video structured description system, explore the data interaction and service interaction between the video monitoring network and the public security business private network, and try to integrate the resources with other public security information systems.

It can be seen that video structured technology firmly grasps the main line of video content information processing and networked sharing application, and strives to fully realize the intelligence of surveillance video information and the intelligence of video surveillance network after several years of technical research and system construction, so as to strengthen the universality of police video application. That is to realize video information processing and analysis based on machine automatic processing, and transform it into information available for public security work through technical means; Realize information sharing and active interoperability among monitoring networks, terminals and police types, and realize network functions such as active monitoring and automatic networking analysis; Expand the application mode of video in police work in an all-round way, greatly improve the ease of use of technology, and realize flexible, simple and diverse video on-demand service applications anytime, anywhere centered on business police.

From the perspective of application prospect, the huge market potential faced by video surveillance technology provides a broad application prospect for video structuring technology. At present, many domestic monitoring enterprises are fully carrying out video structured technology research and product development, and establishing a technology system with completely independent intellectual property rights. At the same time, it also drives the healthy development of a large number of national industries such as related chip manufacturing and software and hardware product development. In fact, all products under China's SVAC and 28181 standards can be incorporated into this system. Under this system, we can eliminate the false and preserve the true of video, carry out secondary analysis, merger and mining of video, carry out real-time and post event intelligent analysis, and integrate video applications into various applications of the industry in combination with industry management.

To sum up, from massive video to extracting key information data by structured technology, and then to big data platform and its industrial applications, this is the main line of product development of monitoring enterprises, and also represents a new idea related to Security Innovation in the new era.
