摘　　要：以徐州某液压挖掘机为模型,不借助任何的商业图形引擎,自主设计并开发了基于虚拟现实的液压挖掘机视景仿真系统.通过动态地形和基于图形处理器的纹理融合方法实现了挖掘机与地形的动态交互,并采用不同角度、不同尺寸的多个显示屏幕的视景图形无缝拼接技术为操作人员提供了360°的虚拟场景.结论表明:开发的视景仿真系统真实感强,有极佳的交互性,为驾驶培训人员提供了全天候、实用、安全、经济的辅助训练手段.With a hydraulic excavator in Xuzhou as a model, without resorting to any commercial graphics engine, the visual simulation system for hydraulic excavator based on virtual reality was de- signed and developed independently. Through the dynamic terrain and graphic processing unit based terrain-rendering methods, the dynamic interaction between the excavator and terrain was realized, and by using seamless conjoint technology of the graphic scenes in multi-channels setting with different angle layout and different sizes, the operator 360° of virtual scene was provided. The visual scene simulation system has a very strong sense of reality, and has an excellent interactivity, which provides the driving training personnel around-the-clock, practical, safe, and economic auxiliary training means.
