IP Camera analysis abnormal event analysis applications

IP Camera analysis abnormal event analysis applications
Today's society is a densely populated, highly complex and highly mobile society, faced with emergencies and abnormal events, more and more of its difficulty and importance of monitoring has become increasingly prominent. Most of the existing video surveillance system within the scene just right monitoring and tracking of moving targets for further recognition and behavior understanding and so very little. Although more and more people continue to build large video surveillance systems, but these control systems are still only provides video forensics tool afterwards.
However, the purpose of monitoring is to monitor the scene unusual event or monitoring the behavior of an object detection and analysis. In the long video sequences using artificial methods to handle such work is neither practical nor economical, so using a computer in a video sequence for video intelligent automatic detection is very important.
Intelligent video analysis technology to analyze abnormal events core algorithms and techniques needed to do support, these core algorithms include:
One would be human behavior modeling virtual reality technology.
2.3D modeling techniques, through the high-definition Network Camera scene of the actual reference measurements for model calibration to build scenes, so that it can calculate the precise structure of objects in the scene at any height and distance between any two points, as a threat to objective analysis provides accurate basis,
3 Object-based label classification, can accurately distinguish people, vehicles and other objects,
4 Based on self-learning adaptive environmental change, understanding and identifying patterns of behavior, self-adaptive learning environment, a variety of built-environment model (streets, walls, water, snow and fog, etc.), can be adjusted automatically according to changes in the environment ,
5 self-test self-protection, the environment and low visibility hampered the field of view, angular offset surveillance cameras, video signal failure, low signal or no signal or other abnormal situation, immediately send alarm,
6 high-definition IP Camera sensitivity adaptive, self-learning environment continues according to the scene and self-tuning parameters, ensure that the external sensitivity adaptive capacity of 7 × 24 a day (in a variety of harsh environments and lighting conditions to provide high reliability testing, No external human intervention adjustment).
