摘　　要：为解决插秧机自动驾驶田间试验受季节、场地等限制的问题,研究了水稻田虚拟试验场景建模与仿真技术。研究了基于分形技术的水稻田地势生成方法,结合耕作区域的数字地图,得到水稻田地形及地势数据。在Creator软件中,加上水稻田内秧苗及地表映像纹理,产生带有垄带、秧苗、水渠等信息的三维场景。研究了基于分形技术的水纹模拟方法,模拟插秧机在田间行走时水纹的动态效果。根据摄像头获取的秧苗作物行与插秧机模型位置偏差,控制插秧机模型在虚拟场景中沿秧苗行前行。To reduce the limitation of the season and place for transplanter automatically driving,the virtual test scene model of rice paddy field was studied.The fractal based rice paddy field terrain and water wave generation methods were studied.The information of terrain and topography in rice paddy field were studied with digital maps.With Multigen Creator,3-D scene with rice seedlings,ridge belts,drains and other information were generated.Fractal based water wave simulation method was used to simulate dynamic effects on water wave while transplanter was driving in paddy field.According to the position error between crop rows and transplanter model,the transplanter model was driving along rice seedlings rows in virtual scene.
