GBDB数据平台中地层剖面全景显示功能的设计与实现

DESIGN AND IMPLEMENTATION OF PANORAMIC DISPLAY OF STRATIGRAPHIC SECTIONS IN GEOBIODIVERSTIY DATABASE(GBDB)

地层剖面是地质学研究的基础。传统的地层剖面展示方式不够直观,缺少现场感。全景显示技术是虚拟现实技术的一种,具有很强的真实感和空间感,可以给用户带来身临其境的访问体验。将全景显示技术应用于野外露头剖面的显示上,实现野外剖面的水平方向360°全方位交互展示,并将之集成在GBDB数据平台中提供在线免费服务。通过这一功能,一方面用户可以在线访问已发布的剖面全景图,查看地层剖面的真实发育情况,了解剖面及视野范围内地理环境的总体面貌和各种细节,另一方面用户可以发布自己采集制作的剖面全景图,实现资料共享。

Stratigraphic sections are the basis of geological studies.Traditional ways to display stratigraphic sections lack a three-dimensional context.Panoramic display is a virtual reality technology that can achieve three-dimensional reality.This technology is applied to interactively display field outcrop sections in360-degree panorama and this function is integrated with the GBDB platform as a free web service.Through this feature,users can access published panorama data in order to obtain three-dimensional outcrop information,and they can also share their panorama data with others.
