According to the high real-time requirements of the 3D visual simulation scene,higher requirements are put on the modeling and optimization of the 3D model.Using the software of Multigen Creator and Terra Vista,taking the"MQ-1 Predator"drone as an example,based on the virtual reality technology,the Degree of Freedom(DOF)is controlled by the process of constructing the drone model.Key technologies such as DOF control technology,model database optimization technology and texture mapping technology are utilized to realize the construction of the dynamic entity model of the drone and the simulation of mission flight.This paper studies the key technologies of virtual environment visual simulation modeling based on drones,realizes the construction of visual simulation models,and models virtual environments to generate efficient and optimized models for subsequent real-time simulation.The application lays a solid foundation for the optimization of 3D models and the precise matching of terrain,imagery and GIS(Geographic Information System)data.
