This application claims the benefit under 35 USC § 119(a) of Korean Patent Application No. 10-2022-0064593 filed on May 26, 2022 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.
At least one example embodiment relates to a disaster response method and system for performing the same, and more particularly, to a disaster response system using a satellite image.
Disasters may include natural disasters, such as extreme weather events and disasters, such as occurrence of accidents, for example, wildfires and the like. Such disasters are surprise and local and may become a bigger issue unless a response corresponding thereto is promptly performed.
To solve such issues, a disaster response system using a satellite image may be considered. However, although a damaged area may be simply specified by using a satellite image, it is not easy to accurately verify a spread degree of damage.
In detail, the disaster response system may have a degraded accuracy when determining an exact scale of damage and may perform prediction corresponding to a level of guess based on past occurrence experience. For example, if it is difficult to predict occurrence of tsunami in the vicinity of the coast, significant damage to property and human life will occur. Therefore, it is important to accurately calculate a scale of damage in a situation in which an input size of manpower for recovery needs to be predicted.
An objective of at least one example embodiment is to provide a disaster response system using a satellite image.

The AI server 300 may include a communicator 310, a processor 320, a memory 330, and a running processor 340. The communicator 310 may transmit and receive data to and from the disaster response system 1000 or an external device, such as another AI apparatus.
The processor 320 may infer a result value for new input data using a learning model and may generate a response or a control instruction based on the inferred result value. The learning model may be a model that is being trained or trained stored in a model storage 331, which is described in the following.
The memory 330 may include the model storage 331. The model storage 331 may store the model (or, an artificial neural network 332) being trained or trained through the running processor 240. An example of the running processor 340 may be a deep learning processor, but is not limited thereto. Machine learning refers to detailed approach method that implements AI and deep learning refers to technology that uses an artificial neural network in a machine learning method.
The running processor 340 may train the artificial neural network 332 using training data. The learning model may be used while being mounted to the AI server 300, or may be used while being mounted to an external device.
The learning model may be implemented using hardware, software, or combination of hardware and software. When a portion of or all of the learning model is implemented as software, at least one instruction that constitutes the learning model may be stored in the memory 330.
The processor 320 may receive satellite images of a damaged area, may detect a change in the satellite images of the damaged area, and may predict a degree of damage according to the change in the satellite images through the damage calculator 230. The damage calculator 230 may calculate first information on the manpower and cost required for recovery of damage in the damaged area based on the predicted degree of damage through interaction with the processor 320. The damage calculator 230 may deliver the first information on the manpower and cost required for recovery of damage to the receiver 110 and an output unit (not shown) such as a display may output the first information.
As described above, the disaster response system 1000 according to an example embodiment may calculate manpower and cost information for recovery of damage in the damaged area and may calculate information on the manpower and the equipment required for recovery of the damaged area in consideration of an amount of time used until the manpower and the equipment arrive. The detailed configuration of predicting a degree of damage in consideration of a change (a change rate, a degree of damage, and a spread degree of damage) in the satellite image based on AI is further described with reference to the accompanying drawings.

Accordingly, the damage calculator 230 may detect a change in the satellite image and a change in weather information in the damaged area through the deep learning module or the AI server 300 and may predict a degree of damage according to the change in the satellite image and the change in the weather information. The damage calculator 230 may calculate first information on the manpower and the cost required for recovery of damage in the damaged area based on the predicted degree of damage and may calculate second information on the support manpower and equipment required for recovery of the damage. Here, in the case of a disaster such as a forest fire, it is possible to accurately predict a degree of damage, a scale of damage and a scale of recovery of damage in the future by further applying weather information, such as a wind direction, a wind speed, a temperature, and a humidity. As another example, in the case of extreme weather, such as earthquake, typhoon, or tsunami, it is possible to accurately predict a degree of damage, a scale of damage, and a scale of recovery of damage in the future by further applying additional weather information related to earthquake, typhoon, or tsunamic from a current point in time to a certain period of time.
Meanwhile, the damage calculator 230 may detect a change in traffic information from a first place to which the support manpower and equipment are to be dispatched to a second place in the damaged area through the deep learning module or the AI server 300. The damage calculator 230 may predict a spread degree of damage according to an arrival time of the support manpower and equipment based on the change in the satellite image, a change in the weather information, and the change in the traffic information. The damage calculator 230 may calculate an additional input of the support manpower and equipment based on the predicted spread degree of damage. Therefore, if the predicted spread degree of damage is predicted to spread to a third place adjacent to the second place, the damage calculator 230 may control a portion of the additional input of the support manpower and equipment to be dispatched to the third place.
Therefore, the damage calculator 230 of the disaster response system 1000 according to the present invention may more accurately predict a scale of damage and a spread degree of damage in the future using AI and may add and distribute the manpower and equipment required for recovery in consideration of the spread degree of damage/damaged area. Also, the damage calculator 230 may predict an arrival time of manpower and equipment required for recovery according to real-time traffic information and, if the degree of damage exceeds a threshold according to a delay of the arrival time, may perform a traffic control of a corresponding path. Therefore, the damage calculator 230 may decrease the arrival time of manpower and equipment required for recovery in the damaged area and may minimize the spread of damage.
