A digital twin may include a replicated digital system based on information in real space. Information about real space may include at least one of the physical properties of the space and/or information about objects existing in the space.

The physical properties of space include gravitational field, magnetic field, electric field, Coriolis force, wind direction, wind speed, temperature, humidity, air resistance, altitude above sea level, air density, viscosity, scattering rate, atmospheric pressure, elastic coefficient, friction coefficient, and vector field in space. It may include at least one of a field) or a tensor field.

Information about objects may include at least one of temperature, viscosity, absorption rate, reflectance, transmittance, scattering rate, attenuation rate, elastic coefficient, or friction coefficient at the volume or surface of the object.

The collision map may be generated based on information about the space associated with the image, which is scanned or photographed using an imaging device (eg, device, etc.). The collision map may include a 3D model.

Specifically, the processor 110 may generate a collision map including a 3D model. For example, the processor 110 may provide information about any space (e.g., a space associated with an image and/or depth map received from the device) scanned or photographed using an imaging device (e.g., a device, etc.). Spatial information can be obtained.

An imaging device may refer to any type of equipment for detecting optical images, converting them into electrical signals, and inputting them into the computing device 100.

Point cloud information may refer to information representing a set of points in a three-dimensional space (eg, 3D model, etc.). Point cloud information may refer to location information of measurement points related to the color and/or location of a basic object existing in an arbitrary space. The basic object may be an object excluding a moving object and a predetermined specific object.

A 3D model is a model (e.g., a 3D map, etc.) created in three dimensions to correspond to an arbitrary space based on point cloud information, and may include point cloud information. For example, the processor 110 may change the point cloud included in the point cloud information in mesh units to generate a 3D model formed in three dimensions corresponding to an arbitrary space. Accordingly, the processor 110 may generate a 3D model by changing the point cloud included in the point cloud information into various other units. For another example, the processor 110 may generate a 3D model formed from a point cloud included in point cloud information. Accordingly, the processor 110 can generate a 3D model by using the point cloud included in the point cloud information without changing it. Here, the arbitrary space may be a space scanned or photographed using an imaging device, and may be a space related to an image and/or a depth map received from the device.

Meanwhile, in some embodiments of the present disclosure, information representing physical phenomena may be reflected in the collision map in advance.

Information representing a physical phenomenon may include at least one of material information or spatial information of an object included in the collision map.

For example, the material information of the object may include at least one of temperature, viscosity, absorption rate, reflectance, transmittance, scattering rate, attenuation rate, elastic coefficient, and/or friction coefficient at the volume or surface of the object. The volume of an object may be a three-dimensional area excluding the surface of the object. For example, if the object is in the form of a gas, the volume of the object may refer to the area occupied by the gas. The computing device 100 may set the total sum of the absorption rate, transmittance, and reflectance on the surface of the object to be 1.

Spatial information may include information about physical elements of space. For example, spatial information includes gravitational field, magnetic field, electric field, Coriolis force, wind direction, wind speed, temperature, humidity, air resistance, altitude above sea level, air density, viscosity, scattering rate, atmospheric pressure, elastic coefficient, friction coefficient, and vector field in space. It may include at least one of a vector field or a tensor field.

A vector field may be a set of vector values assigned to each point in space. A vector value may refer to a physical quantity with size and direction, such as position, speed, force, etc. For example, the vector value may include the strength of the gravitational field, the strength of the magnetic field, etc. However, the above-mentioned vector values are only examples and may include various values.

A tensor field may be a set of tensor values assigned to each point in space. The tensor value may be a value representing the moment of inertia or deformation of an object.

The computing device 100 may set temperature, air density, and atmospheric pressure among spatial information to be proportional to the propagation speed of sound and/or the distance of propagation.

Spatial information may include information about non-physical elements of space. For example, spatial information may include at least one of information about whether there is blocking in space, blocking channel information, information about whether there is a trigger, information about a trigger channel, and/or tag information for programming.

The computing device 100 may change material information of an object reflected on a collision map (eg, virtual reality space, augmented reality space, virtual space, etc.) based on spatial information. For example, the computing device 100 may change the evaporation rate, which is one of the material information of the water in the water cup reflected on the collision map, according to the temperature included in the spatial information.

The material information and spatial information of the object reflected on the collision map may change over time based on rules preset on the collision map.

Preset laws may include physical laws, mechanical laws, etc. For example, preset laws may include Newton's law of gravity, Einstein's general theory of relativity, etc. For example, the preset law is the first law in which the strength of attraction is inversely proportional to the cube of the distance, the second law in which the gravitational constant G is greater than the actual value, etc., are arbitrary laws that do not exist previously set by the environment or the user. may include. However, the preset rule is not limited to this and may be determined depending on the environment.

Newton's law of gravity and Einstein's general theory of relativity explain how objects with mass interact with objects with different masses, but even if the assumptions are the same, the results may differ depending on the theory. Therefore, the material information and spatial information of the object reflected on the collision map affect each other (for example, the effect between the material information of the first object and the material information of the second object, the material information of the first object and the first object) (effect between spatial information, influence between first spatial information and second spatial information of a second space different from the first space, etc.), may change over time based on a rule preset on the collision map.

When placing a virtual object on a collision map, the computing device 100 may determine material information of the virtual object in a preset manner. The predetermined method may include a method of arbitrarily determining among a plurality of material information, a method of setting the material information of a real object corresponding to a virtual object, etc.

In some embodiments of the present disclosure, the collision map may reflect object recognition information in advance. Object recognition information is information required to recognize an object and may include at least one of the type of object and/or the location of the object. The memory 130 of the computing device 100 may store at least one of object material information, spatial information, and/or object recognition information in advance.

In some embodiments of the present disclosure, the computing device 100 may map information about an object to an area corresponding to recognition information of the object on a collision map.

In some embodiments of the present disclosure, the computing device 100 classifies objects included in query data (e.g., images, etc.) using a pre-trained artificial intelligence-based image classification model or image segmentation model, and classifies them. Attribute information about the object including material information and object recognition information of a pre-stored object corresponding to the object can be obtained. The computing device 100 may automatically reflect the material information about the object on the collision map without manually mapping the material information about the object using this artificial intelligence-based classification or segmentation model.

In some embodiments of the present disclosure, the processor 110 of computing device 100 may generate an environment of a collision map based on state information. The processor 110 may reflect the environment of the generated collision map into the collision map.

For example, camera information may include at least one of camera location information and/or direction information. The location information of the camera may include coordinates where the camera exists. The direction information of the camera may include at least one of the direction and/or angle the camera is looking at. Additionally, the camera information may include at least one of focal length information with a specific area, principal point information, lens information, and/or 'sensor and/or film information.' Focal distance information may be information about the distance from the main point of the camera existing in the collision map to a specific area to be photographed. Principal point information may be information about a point where a principal plane intersects an optical axis. Lens information may be information related to the distortion of the lens applied to the camera. Film information may be information related to the size of the film applied to the camera. Sensor information may be information related to a camera sensor applied to a camera. The processor 110 may determine the aspect ratio (ratio of width to height) of an image acquired through a camera based on sensor or film information. Accordingly, the processor 110 may determine camera settings (eg, camera specifications, etc.) applied to the environment of the collision map based on the camera information included in the state information. However, the camera information is not limited to this and may include information from various cameras.
