Standard scientific 硏 "Tracking and enlarging mobile objects..."Use it at night or when it rains"

(Daejeon = Yonhap News) Reporter Lee Ju-young = Researchers in Korea have developed a high-tech CCTV that can track and check faces of people moving at a distance of 60 meters even at night or when it rains.

The Korea Institute of Standards and Science (KRISS, Director Shin Yong-hyun) announced on the 2nd that researchers from the Security Cognitive Technology Research Group (Director Dr. Choi Man-yong) have developed a CCTV that shows the image outside 60 meters in HD quality by integrating a visible camera, a thermal infrared camera, and a movement tracking camera.

The researchers signed a 300 million won technology transfer contract with Hansun Engineering (CEO Lee Do-jin), a video surveillance company, to industrialize this system technology.

 

A high-tech CCTV developed by researchers at the Korea Institute of Standards and Science (KRISS) zoomed in on a person at a distance of 40 meters (right) and a video of the same scene with a conventional HD CCTV.

 

Currently, the widely distributed CCTV is only 2.7m for SD level, which accounts for 70% of CCTV nationwide, and 7.2m for HD level, which accounts for 30% of CCTV, and does not have an enlargement function, making it difficult for people outside the surveillance distance to identify their faces.

However, the CCTV system developed by the researchers shows HD-class quality (90×90 pixels) that can check the face up to 60m away based on the angle of 45 degrees of the monitoring screen, and automatically tracks and enlarges up to 30 people per minute to check face information.

 

 

Basic specifications of all-in-one CCTV developed by researchers at the Korea Institute of Standards and Science (KRISS).

 

Fixed visible cameras are responsible for recording large areas of security, and thermal infrared cameras detect people and obtain location coordinates by measuring the temperature of moving objects when objects appear while monitoring areas such as visible cameras.

The movement tracking camera then stores people's face information as still images up to 60m away with left and right rotation and magnification functions according to the position coordinates secured by the thermal infrared camera.

The researchers explained that this CCTV analyzes the temperature characteristics of each distance based on the specific temperature (34-37℃) of a person, can determine whether a person is a person with 95% accuracy even in specific environments such as night, fog, and rain, and continues to track the path of movement until the target person temporarily lowers his or her head or looks back.

In addition, this CCTV is an integrated structure equipped with a main computer that processes, stores, and transmits data, and automatically transmits data and alarm signals to the comprehensive control room in real time when a security situation occurs.

Dr. Choi Man-yong said, "This technology is a security surveillance technology that can improve the problems of existing CCTVs to identify people at night, bad weather, and long distances, and check multiple face information at once. We will quickly connect to commercialization through technology transfer."
