  • Deep Learning-based accident image detection system
    Deep-learning based accident image detection system detects moving & target objects within CCTV surveillance range and automatically recognize and alert emergency situation such as accidents, reverse driving and fire specified in the management guideline. Compared to computer vision-based video analysis techniques, this AI based system is less influenced by weather or place and detects accidents with higher accuracy.

  • 1) Technology Introduction : Deep Learning-based accident image detection system
  • Object Detection is a research field that analyzes video information by computer instead of a person. Object detection technology is used variously in our daily life including pedestrian detection, vehicle and road sign recognition by analyzing CCTV video. Especially, in the field of traffic flow monitoring, the nationwide road network using CCTV is constantly monitored. In some major section, an accident recognition system is in operation to automatically detect and inform unexpected situations such as traffic jams, collision and falling objects and so forth. Typical accident detection systems are equipped with algorithms based on traditional vision technology, but it is highly sensitive to changes in surrounding environment such as luminance and weather, resulting in pre-detection and detection errors. To solve this problem, DBNtech developed an accident detection system that can detect objects in video like humans in various environments using Deep Learning-based object detection technology. In collaboration with KICT(KOREA INSTITUTE of CIVIL ENGINEERING and BUILDING TECHNOLOGY), we have completed an accident detection system optimized for various environments and have set demonstrate-installed and delivered the system on since 2019.
