Intelligent analysis and retrieval method for video surveillance and system thereof

Abstract

The invention belongs to the field of security technologies and relates to an intelligent analysis and retrieval method for video surveillance and a system thereof. The intelligent analysis and retrieval method for video surveillance and the system thereof resolve the technical problems that an existing technology design is not reasonable enough and the like. The intelligent analysis and retrieval method for video surveillance comprises the following steps: (1) video enhancement and (2) video retrieval, wherein the step of the video retrieval comprises dynamic analysis, coding recombination, result marking and behavior analysis. A dynamic analysis module is connected with a coding recombination module. A result marking module and a behavior analysis module are both connected with the coding recombination module. A video enhancement module is connected with the dynamic analysis module or the coding recombination module. The intelligent analysis and retrieval method for video surveillance and the system thereof have the advantages of combining image enhancement, retrieval compression, intelligent analysis and abstract statistics into one, embodying five characteristics of being advanced, high-efficiency, reliable, convenient and practical in use, achieving the enhancement of video images, the retrieval and compression of video documents, the intelligent analysis of behaviors of people and automobiles, and the like, thus obtaining the needed information rapidly and accurately and being capable of providing strong and effective criminal investigation supports for public security officers to scout and solve a case.

Description

technical field [0001] The invention belongs to the field of security technology and relates to video monitoring, in particular to an intelligent analysis and retrieval method and system for video monitoring. Background technique [0002] With the further development of social economy, our country has invested a lot of manpower and material resources in criminal investigation, and it has become the theme of today's public security departments to ask for quality, police force and combat effectiveness from science and technology. With the deepening of the safe city system and the large-scale construction of social monitoring, the problem of reliable collection and storage of urban road video has been solved, and a large amount of valuable first-hand on-site monitoring image data has been accumulated, which provides a strong support for the investigation. Surveillance video to find clues to solve crimes has become the most commonly used method in criminal investigation and solv...

Problems solved by technology

[0003] 1. In the face of harsh environments, the image quality of the monitoring system is greatly reduced in the dark and low light at night, in severe fog and sandy weather, or when local light is too bright, resulting in poor video image quality. Poor, poor quality of video data, the police handling the case cannot get useful information from it, making it difficult to solve the case and inefficient

[0004] 2. At present, video surveillance generally has shortcomings such as unreasonable camera positions and less effective information. In the process of case evidence collection and analysis, it often takes a lot of manpower and time to view massive video data, which seriously restricts its detection efficiency. Traditional manual retrieval There are still inevitable human misjudgments and misjudgments in the evidence collection work, so the problem of low video review efficiency in the actual combat of public security surveillance video investigations needs to be solved urgently

[0005] 3. In most cases at this stage, the criminal investigation team applies to the relevant departments to dispatch relevant monitoring data after the incident, and then conducts manual semi-automatic search and judgment. Due to the on-site environment, the captured images are unsatisfactory and cannot be seen. It is not convenient for the public security department or the traffic management department to monitor and process the details clearly. The public security police are basically helpless when the video quality is low. Faced with a large amount of video surveillance data, they can only review one by one time-consuming and laborious. The criminal investigation police are very distressed by this.

[0006] 4. Watching low-quality videos for a long time may increase the burden on people's eyes, easily cause visual fatigue, and even cause dizziness. covered or blurred, resulting in a degraded image

[0008] Although the above scheme has improved the video analysis efficiency to a certain extent, it is still difficult to obtain the information needed in the video conveniently. It only shortens the length of the entire video, but does not affect the effect, details, and associations between videos. etc. did not do anything
