    摘要:

    為了遠(yuǎn)程控制超低空無人飛行器起降和監(jiān)視其飛行狀況，設(shè)計(jì)了基于虛擬現(xiàn)實(shí)技術(shù)的導(dǎo)航與控制方法。借助Multigen Creator軟件，建立了飛行器的三維仿真模型，由DEM數(shù)據(jù)生成了地形場(chǎng)景，研究了三維模型的驅(qū)動(dòng)方法。根據(jù)飛行器上裝載的GPS接收機(jī)和其他傳感檢測(cè)設(shè)備實(shí)時(shí)傳遞的參數(shù)對(duì)虛擬環(huán)境下的飛行器模型及飛行場(chǎng)景進(jìn)行驅(qū)動(dòng)。同時(shí)給出反饋信號(hào)，控制飛行器按預(yù)定路線和姿態(tài)飛行，利用GIS技術(shù)，在數(shù)字地圖上顯示飛行軌跡。對(duì)飛行器的飛行軌跡和飛行姿態(tài)進(jìn)行實(shí)時(shí)控制，仿真試驗(yàn)表明，對(duì)飛行器的遠(yuǎn)程導(dǎo)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.
