Design of an UAV simulation training and assessment system based on Unity3D

摘要

Aiming at the shortage of practical training for UAV and the present situation of virtual training system design, the methods of combining virtual simulation technology with UAV maintenance training was put forward in the paper. The approximating learning and training environment was simulated. The system design followed the principle of lifelike, completeness, practicability, modular and openness. The ports were reserved for later functional extensions. The database engine of SQLite was used to storing and managing system information, and the communication between SQLite and Unity was achieved by scripting. With the help of center point surround technology, quaternion rotating technology and mouse pickup technology, the interactions on the plane were carried out in the environment of Unity3D. Finally, the function modules of equipment learning, simulation training, assessment and evaluation were demonstrated in the paper. The performance indexes of the UAV simulation training system, such as real-time, normative and fidelity, could meet the needs of UAV equipment training and teaching.
