摘  要：
由于田间作业环境复杂,插秧机卫星自动导航工作时GPS数据不能准确反映秧苗位置,达不到相应的作业要求.为此,提出一种利用全站仪检验秧苗路径的方法,检验插秧机的作业精度.通过研究全站仪单点静态测量所获取的秧苗点数据,得到秧苗路径的直线度和秧苗路径的对行精度,进而评估插秧机的作业精度.对相关数据进行分析可得:秧苗路径直线度的最小值和最大值分别为3. 08、4. 93 cm,最小和最大均方根误差分别为4. 299、6. 263 cm;秧苗路径的对行精度最小值和最大值分别为5. 17、15. 53 cm,最小和最大均方根误差分别为4. 29、5. 43 cm.结果表明,该方法可实现对农机田间自动导航作业精度的量化评估.

摘  要：
Due to the complicated working environment in the field,the GPS data cannot accurately reflect the position of the seedlings during the automatic navigation of the rice transplanter,and may not meet the corresponding operational requirements. Therefore,in order to verify the accuracy of the satellite navigation operation of the rice transplanter,a method of using the total station to test the seedling path was proposed to verify the accuracy of the transplanter. By studying the data of the seedling point obtained by the single-point static measurement of the total station,the straightness of the seedling row and the parallel accuracy of the seedling rows were obtained, and the operation precision of the transplanter was evaluated. From the analysis of relevant data,the minimum and maximum values of the straightness of the seedling row were 3. 08 cm and 4. 93 cm,respectively,and the minimum and maximum root mean square error were 4. 299 cm and 6. 263 cm,respectively; the minimum and maximum values of parallel accuracy of seedling rows were 5. 17 cm and 15. 53 cm,respectively,and the minimum and maximum root mean square errors were 4. 29 cm and 5. 43 cm,respectively. The results showed that the method can achieve quantitative evaluation of the accuracy of automatic navigation operations in agricultural machinery fields.
