Title:
DEVICE AND METHOD FOR RECORDING AND RECONSTRUCTING SCENE IN VIRTUAL SPACE
Document Type and Number:
WIPO Patent Application WO/2023/233751
Kind Code:
A1
Abstract:
The present invention provides a device and method for recording and reconstructing a scene, which can easily extract and reconstruct a desired scene on the basis of semantic information and which is capable of appropriate scene extraction with consideration for object interaction. To achieve this objective, the present invention provides a device for recording and reconstructing a scene that records and reconstructs a scene in a virtual space, the device comprising: a geometry recording unit that records geometry information expressing the shape and appearance of objects in a scene; a record recording unit that records record information, which is time series information about events enacted by the objects; a knowledge graph recording unit that records the context of the scene as a knowledge graph; and a scene reconstruction unit that reconstructs a desired scene in the virtual space by identifying a scene to be reconstructed from the context of the scene recorded by the knowledge graph recording unit, and obtaining and reintegrating the geometry information and record information necessary to reconstruct the scene.
