摘要
针对智能拖拉机在复杂多变、操控任务繁多的农业作业条件下难以实现全自主智能驾驶的不足,设计一种基于虚拟现实技术的拖拉机遥操作驾驶系统。首先,开发了虚拟现实主控端硬件系统,包括拖拉机驾驶模拟器及方向盘、挡住、油门、刹车、离合等机构的信号采集和检测电路;并基于VC++平台,结合OpenGL图形程序接口及3ds Max,构建以南京农业大学浦口校区为工作场景的拖拉机遥操作虚拟现实软件系统。实验表明,拖拉机遥操作驾驶虚拟现实系统简单稳定,易于操纵,具有良好的交互性和应用性。
In order to overcome the difficulty of fully autonomous driving of intelligent tractor under flexible and variable working conditions,a tele-operation tractor driving system based on virtual reality technology is designed.Firstly,the controlling terminal hardware system is developed,which is composed of tractor driving simulator,the signal acquisition and detection circuit for each mechanism and data capture system.Then,based on VC ＋＋ platform,combined with OpenGL graphics programming interface and 3ds Max software,the tractor tele-operation virtual reality system software whose work scene is Pukou campus of Nanjing Agricultural University is constructed.Finally,the connection between the tele-operation virtual reality system and tractor driving simulator is realized.Experiments show that the design of the tractor driver tele-operation virtual reality system is simple and stable,interactive,and easy to manipulate,it also has good immersive feeling.
