AVR Virtual Environment in the New Generation Human Computer Interaction System

摘要

VE (Virtual Environment) provides the three dimensional visual interactive environment for the new generation - the fourth generation natural HCI (Human Computer Interaction) system. Modeling the virtual objects is the key to build VE. The paper focuses on the theory, algorithms and core techniques for AVR (From Actual Reality to Virtual Reality) modeling of virtual environment. Based on the integration of computer vision and computer graphics (CV/CG), the objects in AVR VE are virtualized directly from the shape data (2D images and 3D data) acquired of their counterpart objects in real world by using AVR reconstruction approaches, which provides the AVR VE with a higher-level realism, conciseness and preciseness.
