Abstract: Disclosed is a method and apparatus for evaluating wildfire evacuation vulnerability. A wildfire evacuation vulnerability evaluation method may include identifying wildfire vulnerable areas and critical roads for wildfire evacuation within the wildfire vulnerable areas through a wildfire evacuation vulnerability measure based on origin-destination pairs and failure probability for each road due to wildfires.

Abstract: A smart system for evacuation and rescue support in case of a large building disaster and an operation method for the smart system are disclosed.

Abstract: Provided is a robot control method that controls a robot to guide an evacuation route in response to occurrence of an emergency situation. The robot may acquire evacuation route information on a space from a server when an emergency situation occurs in the space, and may move to a first node closest to the robot among nodes defined in the space and a second node indicated by direction information of the first node based on the evacuation route information and a current location of the robot.

Abstract: Disclosed is a method of generating digital twin content corresponding to a space including objects, such as a work site including work products. The method of generating digital twin content includes obtaining a three-dimensional (3-D) model of the space, disposing, in the 3-D model, a first virtual camera that is synchronized with a first camera that is disposed in the space and that captures at least some of the space, recognizing a object in a first image that is captured by the first camera, generating a 3 -D object that is disposed in the 3-D model and that corresponds to the first object, based on the first object and the first virtual camera, and generating digital twin content including a 3-D object into which a movement of the first object is incorporated.

Abstract: Provided is a station device plurally provided to guide an action order responding to a gun accident to a user in a separate space, the station device including a microphone configured to detect a shooting sound in separate space; a communication unit configured to transmit a detection result of shooting sound to a server and to receive, from the server, a first occurrence location of first gun accident determined based on a detection result of first shooting sound detected by a first station device in separate space; an action determination unit configured to determine an action to be output by the station device in response to the first occurrence location using an action table in which an action to be output by the station device is mapped according to an occurrence location of a gun accident and a time; and an action output unit configured to output the determined action.

Abstract: An evacuation inducing method and system are disclosed. The evacuation inducing method includes: detecting the location of an emergency situation in a target region; generating prediction data for each unit path included in the target region, which predicts until when each unit path will remain safe, by predicting a spread of the emergency situation from the location of the emergency situation by using a spread prediction algorithm; predicting the degree of congestion on each unit path included in the target region and the expected travel time by taking into consideration the number of objects included in the target region that is preliminarily identified; creating an evacuation route based on the prediction data, the degree of congestion on each unit path, and the expected travel time; and initiating guidance for distributing and evacuating the objects based on the created evacuation route.

Abstract: There is provided a method of controlling a robot, which is performed by the robot that travels within a space. The robot identifies a person to be rescued, among persons within a space, by using a camera while travelling within the space, determines a distance between the robot and the person to be rescued based on depth information that is obtained by the camera and that is associated with the person to be rescued, and transmits information including the determined distance to a control server for the space.

Abstract: Provided is a method of creating digital twin content for a space based on object recognition in the space. A method of creating digital twin content includes identifying, by a computer system, an object in a space using a camera, determining a value of a parameter associated with the camera to define (or display) the identified object with a predetermined first size at a predetermined location on an image captured by the camera or a screen on which the image is displayed, and using a control result value based on the determined value of the parameter and the location information of the identified object to create the digital twin content for the space.

Abstract: A system for detecting an accident risk in a working place that can determine a work stage of the working place where various kinds of works, such as a cargo loading and unloading workshop, are performed or determine whether or not there is a risk that an accident may occurs in the working place is disclosed. In the disclosed system for detecting the accident risk in the working place, a camera is used to photograph the working place, only information about an object recognized by analyzing the image is transmitted to the server without transmitting the photographed image to the server, thereby minimizing an amount of information transmitted from the camera to the server.

Abstract: A system and method may detect one or more shooting sounds and provide guidance to one or more evacuating people when an active shooting event has occurred indoors, thereby minimizing a secondary damage. The system comprises: a plurality of stations configured to detect one or more shooting sounds and transmit detection of the one or more shooting sounds; and a response server configured to receive the detection of one or more shooting sounds over a communication network, to generate action commands, respectively corresponding to each of the stations, based on the detection of the one or more shooting sounds, and to transmit the respective action commands to the each of the corresponding stations over the communication network.

Abstract: Disclosed is a context-aware real-time spatial intelligence provision system that estimates the locations of persons or things captured in a video by extracting objects representative of the persons and the things from the video captured by viewing a real space and placing the extracted objects in a virtual space to which a digital twin technique is applied. The disclosed context-aware real-time spatial intelligence provision system allows people to keep the distance between each other indoors, thereby preventing the spread of an infectious disease such as COVID-19.
