基于RTK-GPS的智能微耕机导航系统
Journal of Agricultural Mechanization Research（2021）
Abstract
针对丘陵区田块小、不规则及耕作难等问题,设计了一种基于RTK-GPS的智能微耕机导航系统,并结合实际作业要求,基于梭形法提出了任意四边形田块路径规划算法,实现作业区域全覆盖路径规划.同时,阐述了导航系统整体设计方案.在机具作业过程中,通过RTK-GPS实时获取微耕机的位姿信息,实时校正机具作业偏差,通过将信号输入继电器,控制气动阀门,实现微耕机离合器的闭合,完成机具智能作业.田间试验结果表明:微耕机作业过程中,直线行驶时行驶路线与规划路线的横向偏差均值为2 cm,拐弯时横向偏差较大,整体来讲路径规划合理.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
