Abstract

Provided is a seismic vulnerability analysis system of a user's living space. The system includes: an image receiving unit configured to receive image information obtained by photographing a living space, where various things are disposed, through a camera; an image signal processing unit configured to recognize the thing photographed in the image information as an object, extract a position and size of the object in a three-dimensional space, and convert the extracted position and size into spatial information; and an earthquake simulation unit configured to simulate motion phenomena of the objects in the space when an earthquake occurs according to simulated seismic conditions based on the spatial information.

First claim

What is claimed is:

1. A seismic vulnerability analysis system of a user's living space, the system comprising:
an image receiving unit configured to receive image information obtained by photographing a living space, where various things are disposed, through a camera;
an image signal processing unit configured to recognize the thing photographed in the image information as an object, extract a position and size of the object in a three-dimensional space, and convert the extracted position and size into spatial information; and
an earthquake simulation unit configured to simulate motion phenomena of the objects in the space when an earthquake occurs according to simulated seismic conditions based on the spatial information.

2. The system of claim 1 , wherein the image signal processing unit recognizes a type of the object through an artificial neural network.

3. The system of claim 1 , wherein the image signal processing unit uses information on physical properties of at least one of density, weight, compressive strength, tensile strength, friction coefficient, Young's modulus, Poisson's ratio, and rebound coefficient of the recognized object together with spatial information.

4. The system of claim 1 , wherein the image signal processing unit uses information on a binding method for a contact target of the recognized object together with spatial information.

5. The system of claim 1 , further comprising a living space information providing unit configured to provide at least one living space information among an address, the number of floors, an earthquake-resistant design, and geological information of the living space,
wherein an earthquake condition is determined by a strength of an earthquake and the living space information.

6. The system of claim 1 , further comprising a transmission unit configured to provide a simulation process and a result to a display device or a virtual reality (VR) device for indirectly experiencing an earthquake in a living space by providing a process of performing the earthquake simulation to a user.

7. A seismic vulnerability analysis method of a user's living space in a seismic vulnerability analysis system of user's living space including an image receiving unit, an image signal processing unit, and an earthquake simulation unit, the method comprising:
receiving, by the image receiving unit, image information of a user's photographed living space;
recognizing, by the image signal processing unit, a thing photographed in the image information as an object, extracting a position and size of the object in a three-dimensional space, and converting the extracted object into spatial information; and
simulating, by the earthquake simulation unit, motion phenomena of the objects in the space when an earthquake occurs according to a simulated seismic condition based on the spatial information.
