Application of 3D Model from UAV Photogrammetry in Virtual Field Education

摘要

The Virtual Field Education System (VFES) has been developed based on unmanned aerial vehicle (UAV), Digital photogrammetry, multi-scale 3D model, virtual reality, Global Positioning System (GPS) and spatial database. The VFES has integrated a large number of rich geoscience teaching resources. The application of the VFES breaks up the traditional teaching methods so that we can teach in a virtual field environment. Students can establish mental perception of field environment, learn knowledge of field, master the skills of field geoscience, and expand the scope of knowledge.
