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 technolo-gy,superimposed on an electronic map and published.The construction and application of field prac-tice platform expands the geographical scope,and reduces the cost and risk of field practice.The con-struction 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 virtu-al simulation of practical teaching.
