1 is a configuration diagram of a virtual reality space creation system according to an embodiment of the present invention. Referring to FIG. 1, the virtual reality space creation system 1 may include a scanning device 110 and a virtual reality space creation device 120. The scanning device 110 and the virtual reality space creation device 120 are exemplary illustrations of components that can be controlled by the virtual reality space creation system 1.

Each component of the virtual reality space creation system 1 of FIG. 1 is generally connected through a network. For example, as shown in FIG. 1, the virtual reality space creation device 120 may be connected to the scanning device 110 simultaneously or at time intervals.

Network refers to a connection structure that allows information exchange between nodes such as terminals and servers, including Local Area Network (LAN), Wide Area Network (WAN), and World Wide Area Network (WWW). Wide Web), wired and wireless data communication networks, telephone networks, wired and wireless television communication networks, etc. Examples of wireless data communication networks include 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), Wi-Fi, Bluetooth communication, infrared communication, and ultrasound. This includes, but is not limited to, communication, Visible Light Communication (VLC), LiFi, etc.

The scanning device 110 may scan the target space and transmit it to the virtual reality space creation device 120.

The scanning device 110 is a 3D scanning device 110 and may include a general scanning device 111 and a precise scanning device 112. The reason why the general scan device 111 and the precision scan device 112 are used together is that when the scan device 110 3D scans a large space, the sensor shadow area caused by objects placed in real space, the scan device 110 Depending on the precision, the placed objects may not be precise, so the virtual reality spatial information scanned for the target space may contain errors, and if virtual reality spatial information containing errors is used in virtual reality, the user may become immersed when using virtual reality. may be disturbed.

Therefore, the scanning device 110 is a device that performs a broad scan of a large space using the general scanning device 111, scans the target space, and performs a precise scan of an object using the precise scanning device 112. Additional objects can be scanned as . At this time, the general scanning device 111 does not separately store information on objects located in the target space.

The virtual reality space generating device 120 may scan the target space using the scanning device 110 to generate virtual reality space information. Here, virtual reality spatial information is 3D information about a large space obtained from 3D design software or a 3D scanning device 110, and includes the coordinates (x, y, z) of vertices like a 3D object. Consisting of the order (index) for expressing vertices as triangle or quadruple faces, the normal direction vector of each vertex or face, and the texture coordinates (U, V) of each face, etc. It could be.

Specifically, the virtual reality space generating device 120 may readjust additional objects inserted into the third virtual reality space information based on the first depth buffer information, the second depth buffer information, and the third depth buffer information.

For example, the virtual reality space generating device 120 compares the first depth buffer information and the second depth buffer information to derive the location and size of the removed object, and uses the second depth buffer information and the third depth buffer information to determine the location and size of the removed object. By comparison, the location and size of the additional object can be derived, and the location and size of the additional object can be readjusted to correspond to the location and size of the removed object.
