RXR-SM: Creation of Sharing Spaces and Geometry 3D Reconstruction Using RGB-D

Abstract

In this study, we propose a remote XR system based on a space model (RXR-SM) that utilises 3D spatial reconstruction techniques to capture and transmit real-time spatial information to remote collaborators. The host client generates a 3D space using the RGB-D data in real time and converts it into triangular particle data to be transmitted to the edge server. The edge server receives the transmitted triangular particle data and stores them in a list array, and asynchronously delivers data upon request from the guest client. The guest client converts the received triangular particle data into rendering information and visually renders the graphics. Ultimately, a remote collaboration system can be integrated with a cloud system, thus allowing the storage of historical data and showcasing the temporal evolution of the space. The proposed RXR-SM system supports situations in which immediate and intuitive spatial information must be conveyed under critical circumstances.
