利用虚拟现实技术再现海洋自然地理环境

Marine Nature Geographic Environment Reappearance by Using Virtual Reality Techniques

虚拟现实技术是当代计算机科学的一个研究热点，将虚拟现实技术引入到测绘领域中，为测绘保障提供了一个全新的手段。本文首先分析虚拟现实技术的发展现状，然后着重介绍了虚拟现实技术的系统组成，以及相配套的硬、软件。最后，讨论海洋自然地理环境虚拟现实系统的设计等。

Virtual reality technique is a study hot point in computer science now. A completely new means is provided for surveying and mapping assurance by introducing virtUal reality technique to the field of surveying and mapping. In this paper, the developing situation of virual reality technique is analyzed first. Then the system component, hardware and software of virtual reality technique is recommended. The virtual reappearance of oceanic nature geographic environment is expounded at last. The spatial geographic information base, three dimensional stereoscopic modeling technique and the design of marine nature geographic environment virtual reality system etc. are discussed as principal research contents.
