元宇宙环境下玉米免耕播种机作业机组仿真与试验

针对玉米免耕播种机研发周期长和研发成本高等问题，本文将元宇宙技术应用于玉米免耕播种机作业机组的仿真试验。基于元宇宙系统架构构建仿真平台，在元宇宙环境下，采用标线法和转换法对虚拟农场中场景进行高度还原，构建沉浸式玉米免耕播种机驾驶平台并进行交互性能测试，验证沉浸式玉米免耕播种机驾驶平台交互性能。在此基础上，在不同行驶速度下进行播种性能仿真试验，当玉米免耕播种作业机组前进速度不断增大时，播种质量整体呈下降趋势，趋势接近实际田间试验结果，株距合格率大于88.52%、重播率小于6.97%、漏播率小于4.51%。试验结果表明，本文设计实现的元宇宙虚拟播种仿真平台能够用于玉米播种试验，对降低玉米免耕播种机研发成本、缩短玉米免耕播种机研发周期具有重要意义。

Simulation and Experiment of Corn No-till Planter Operating Unit in Meta-universe Environment

Aiming at the problems of long R&D cycle and high R&D cost of no-tillage planter for maize, it was proposed to apply the meta-universe technology to the simulation of corn no-tillage planter operating unit. Based on the architecture of the meta-universe system, the simulation platform was constructed, and the scenes in the virtual farm were highly restored under the meta-universe environment by using the marking line method and the transformation method, and an immersive corn no-tillage planter driving platform was constructed and tested for the interactivity, to verify that the immersive corn no-tillage planter driving platform had better interactivity. The interactive performance of the immersive corn no-till planter driving platform was verified to be better. On this, seeding performance simulation tests were carried out at different driving speeds, and the overall seeding quality showed a decreasing trend when the forward speed of the corn no-tillage planter unit was increasing, and the overall trend was close to the actual field test results, and the spacing pass rate was greater than 88.52%, the reseeding rate was less than 6.97%, the omission rate was less than 4.51%. The test results showed that the virtual seeding simulation platform designed and implemented can be used for corn seeding experimental research, which was of great significance to reduce the research and development cost of no-tillage seeding machine and shorten the research and development cycle of no-tillage seeding machine for corn.
