1. A method of creating digital twin content for a space based on an object recognition in the space, performed by a computer system, the method comprising:
identifying an object in the space using a camera included in the computer system;
determining a value of a parameter associated with the camera to define the identified object with a predetermined first size at a predetermined first location on an image captured by the camera of the computer system or a screen on which the image is displayed, the object being defined with the first size at the first location on the image or the screen by at least one of i) that the camera is rotated by a driving unit and ii) a zoom of the camera is adjusted, based on the determined value of the parameter; and
using a control result value of the camera based on the determined value of the parameter and location information of the identified object on the image or the screen to create the digital twin content for the space,
wherein the digital twin content includes a correspondence object corresponding to the identified object, and
by iteratively performing the identifying, the determining, and the using as the object moves, the moving object is tracked to be defined with the first size at the first location on the image or the screen and a movement of the object is represented as a movement of the correspondence object in the digital twin content, and
wherein the parameter includes pan information, tilt information, and zoom information of the camera,
in response to rotation of the camera or the computer system equipped with the camera as a motor of the driving unit is controlled by first rotation angle information of the camera based on the pan information and second rotation angle information of the camera based on the tilt information, the camera is controlled to define the object at the first location on the image or the screen,
as the camera is controlled to zoom out or zoom in according to the zoom information, the camera is controlled to define the object with the first size at the first location on the image or the screen, and
the digital twin content is created by processing the first rotation angle information, the second rotation angle information, the zoom information, and the location information with a three-dimensional (3D) content creator.
