基于Krpano的全景校园漫游的设计与实现

Design and Implementation of Panoramic Campus Roam Based on Krpano

在数字校园建设和发展中,以虚拟全景校园漫游为基础的校园信息化平台能够为师生提供全新的沉浸式浏览体验,并提供更集中的信息交互功能。虚拟现实技术能够真实地再现现实环境,通过交互式操作,用户可以获得与真实环境相似的感受和体验,其中全景漫游是虚拟现实技术的一种典型应用。该文以南开大学滨海学院为实践区域,基于Krpano平台,利用Google Maps地图服务,采用全景图制作技术、SQL数据库技术和计算机网络技术搭建了一个虚拟全景校园漫游系统,并可跨系统、跨设备使用。系统实现了2D校园全景和谷歌地图信息服务功能,并提供了搭载陀螺仪传感器的可穿戴式VR设备使用的WebVR全景显示,满足了数字校园分布式、便于使用的需求。实践证明了基于Krpano框架设计能深度定制虚拟全景校园漫游系统的相关功能,能有效开发并拓展系统,并具有重要的实践意义。

In the construction and development of digital campus,the campus information platform based on virtual panoramic campus roam can provide teachers and students with a brand new immersive browsing experience and more centralized information interaction demand.The real environment can be reproduced truly by virtual reality technology.Through interactive operation,users can get the feeling and experience similar to the real environment.Panoramic roaming is a typical application of virtual reality technology.Taking Nankai University Binhai College as the practice area,based on Krpano platform,using Google Maps service,panorama production technology,SQL database technology and computer network technology,we construct a virtual panoramic campus roaming system,which can be used across systems and devices.A 2D campus panorama and Google Map service is realized,as well as the WebVR panorama display for wearable VR devices equipped with gyroscope sensors,which meets the distributed and easy-to-use need of digital campus.Therefore,the system based on Krpano has important value of practical significance,which can deeply customize the relevant functions of the virtual panoramic roam,as well as expand the system effectively.
