中文摘要:为了远程控制超低空无人飞行器起降和监视其飞行状况,设计了基于虚拟现实技术的导航与控制方法。借助Multigen Creator软件,建立了飞行器的三维仿真模型,由DEM数据生成了地形场景,研究了三维模型的驱动方法。根据飞行器上装载的GPS接收机和其他传感检测设备实时传递的参数对虚拟环境下的飞行器模型及飞行场景进行驱动。同时给出反馈信号,控制飞行器按预定路线和姿态飞行,利用GIS技术,在数字地图上显示飞行轨迹。对飞行器的飞行轨迹和飞行姿态进行实时控制,仿真试验表明,对飞行器的远程导航控制是可行的

Abstract: 。To control the take-off, landing and flying of ultra-low altitude UAV remotely, navigation and control methods were studied with virtual reality technology. With the aid of Multigen Creator, we built 3-D model of UAV, generated terrain by DEM data, and studied drive technology. According to the parameters from GPS receiver and other sensors fixed on the UAV, the 3-D model and scenes were derived. Meanwhile, feed back signal was given to adjust the plane’s gesture to insure the plane to fly along the route. GIS technology was used to display the UAV trace in digital map. Virtual experiment shows the feasibility of navigation and control of ultra-low altitude UAV.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
