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.
