摘　　要：传统野外实践受地域、交通、时间、天气等多重因素的制约,难以兼顾实践内容、成本及人员的安全。采集不同时间、不同地点的影像素材制作VR实景,叠加至电子地图并通过互联网发布,可实现实践对象空天地一体化的多尺度展示。基于VR技术构建与应用野外实践平台,拓展了野外实践的地域范围,同时降低教学成本和风险。VR实景的制作及发布所涉及的技术门槛低,节点的拓展性强,有利于提高野外实践教学资源共享效益,为全国性的仿真平台建设提供参考。Traditional field practice is restricted by multiple factors such as region,traffic,time and weather,so it is difficult to consider the practice content,cost and personnel safety.The VR model of field practice with multiple times and locations was designed based on panoramic photography technology,superimposed on an electronic map and published.The construction and application of field practice platform expands the geographical scope,and reduces the cost and risk of field practice.The construction and sharing of VR real scenes involve low technical threshold and strong scalability,which is conducive to promoting the sharing of practical teaching resources and providing reference for the virtual simulation of practical teaching.
