Context-aware real-time spatial intelligence provision system and method using converted three-dimensional objects coordinates from a single video source of a surveillance camera

A context-aware real-time spatial intelligence provision system comprising:

• a video stream receiver unit configured to receive a video captured by a camera;
• a virtual digital twin space model management unit configured to generate and manage a virtual space obtained by simulating the specific space using a digital twin technique;
• a digital twin location management unit configured to estimate locations of things in the specific space corresponding to objects, extracted from the video, by comparing the video and the virtual space view;
• a distance calculation unit configured to calculate a distance between the things in the specific space based on the estimated locations;
• and
• a message sending unit configured to send a warning message to the things in the specific space, in response to the estimated distance falling within a predetermined distance,
• wherein the things are persons in the specific space.
