Abstract:

The virtualization of the field environment is of great research significance. It is necessary to consider the following questions: how to construct field virtual environments more efficiently and conveniently, and how to achieve higher degree of interaction freedom and better immersive experience in the constructed virtual environment. We proposed a fast construction method of field virtual environment based on panoramic videos. Through the processing of depth estimation and photographic modeling of extracted panoramic images, the reconstructed scenes were divided into far and near scenes with various forms. Finally an immersive field virtual environment was produced, which supported 6-DOF roaming within a certain range. The practicability of this method was quantitatively analyzed and verified by the objective indicators of image quality, and a prototype system with the complete process from the construction to the use of the field virtual environment was developed as an application. The results show that the fast construction method of 6-DOF field virtual environment based on panoramic image could achieve high efficiency and excellent applicability, exhibiting promising prospects in fields such as virtual field geological practice and teaching.
