First of all, it is important to quickly recognize people’s faces in order to identify wanted citizens and law enforcement officers. It is possible to solve this problem by using IoT-technology. For example, in 2015, the Chinese company LLVision has released on the market smart glasses GLXSS.
As of May 2019, the glasses are being used by the Chinese police in transport facilities and have proven to be a highly effective operational tool for identifying wanted persons and persons with fraudulent documents. In addition, the goggles of this modification can also be successfully used to check vehicle registration numbers.
GLXSS is equipped with a quad-core Cortex-A7 processor and comes complete with 1 GB of RAM and 16 GB of internal memory, while an 8-megapixel video camera can record 1080p video. The glasses also support voice recognition and gesture control.
With all these features GLXSS has a mass of only 55 g. The glasses have a built-in 0.25-inch viewfinder with VGA resolution. Data is transmitted via Wi-Fi 802.11 b/g/n and Bluetooth 4.0.
Ensuring coronavirus safety at facilities/places with crowds of people characterized by large areas (multi-story buildings, voluminous structures with complex underground and aboveground structure) is not yet possible without constant 24-hour video monitoring by means of CCTV system.
Huge volumes of received video information require prompt processing. An effective tool for this is the development of domestic engineers in the field of intelligent video analytics. At the same time, as part of the solution for the complex security of places of mass stay of people can be used special video analytic complex based on the model of effective predictive analysis and automated information gathering and processing system (AIS).
The given complex promotes revealing and recognition:
- non-standard behavior of people
- alarm situations
- movements in a prohibited direction aggressive behavior of people: robberies, robberies, fights, vandalism, etc.
- The crossing of control lines
- crowding and crowd formation
- people’s faces
- derelict objects, etc.
Useful functions of intellectual video analytics for social distancing and coronavirus are also object tracking (tracking of a specific object) and quick search of the searched object/object by its appearance in the video archive of events.
The product includes:
- video intellectual modules for solving the above tasks;
- intellectual analytical platform;
- information collection and processing system.
Video intellectual modules of video stream analysis receive an input video signal, analyze the behavior of objects and identify “unwanted events”. The output data can be transmitted to the operational monitors of the security service in real time and to the video archive of the CCTV system.
According to experts, the system of remote contactless scanning and recognition of a person’s psychophysiological state has a good prospect of application in the solution of problems by providing complex safety for large crowds, which can establish a level of its danger for others (aggression, stress, anxiety).
The main useful function of the system is to detect potential terrorists, persons under the influence of alcohol or drugs, increased arousal, etc.
The program of irex international system works on the basis of vibration imaging technology, which registers minor vibrations of a living object with the help of standard technical hardware, such as digital or analog video cameras.
This insignificant vibration (movement of body points in space) reflects the psychophysiological state of a person and the level of his emotional excitement. All this allows remote scanning of people, revealing the level of their aggression and stress, as well as the detection of lies in real-time.
