High Risk Situations Interpreted With Surveillance Software

The Center for Engineering and Industrial Development (CIDESI) developed software for a surveillance system that can detect the behavior of people and analyzes the movement of objects, a method that can distinguish when an unusual event is happening, as the case of an assault or an accident.

The prototype of this software is already installed in the research center located in the Mechatronics Laboratory of Queretaro, in central Mexico

The prototype consists of four cameras placed in the laboratory; they can detect situations that a traditional surveillance system does not, for example, how people behave when they enter the building for the first time. If the way they walk is different, the technology developed in CIDESI records it.

Hugo Jiménez Hernández, head of research at CIDESI said the interesting thing is that the system analyzes the behavior of moving objects, and then decides when an unusual event is happening and notifies it.

“In CIDESI’s design, all surveillance cameras work as a data gathering point and decide whether something is relevant or not; when one of the cameras detects something unusual it sends a signal, focuses and analyzes the event. When uncommon things happen the response time is very fast and the number of events it detects increases”

With this technology, the unusual event is sent to a central server to analyze the flow of moving objects, so that when it locates the event, it reports and saves the corresponding video fragment along with the time and the code of the camera that registered it.

This technology can also elaborate behavioral statistics, for example if the system were installed in a high traffic crossroad, where it would be more probable for an accident to occur in rush hour, the software would report so in order to prevent it.

This information is registered on a data base that obtains and analyzes the statistics, particularly the ones recorded on the day of the unusual event in order to inform about potential risk situations. In the case of an event that requires extra attention, the system can respond within seconds, so an alarm can be activated.

“This technology only records unusual situations and doesn’t require large resources as the traditional surveillance systems, making it a low cost technology and an efficient information system. To detect and anomaly no sequence search on every hour of the surveillance video is needed.”

For the time being, this technology has potential clients in the private and public areas. For example, the Ministry of Transport in Querétaro could employ it as a tool to monitor roads and avenues. And private companies could use a surveillance system oriented toward malls or busy locations.

This technological development was accomplished with the help of the Center of Research in Applied and Advanced Technology (CICATA), the National Polytechnic Institute (IPN) and the Autonomous University of Queretaro (UAQ). Currently, is in process of being patented and obtain copyrights. (Agencia ID)
