农业装备速度信息获取方法研究进展

he acquisition of speed information is important to precision agriculture. In this paper, the current speed information acquisition methods of agricultural equipment were introduced, which can be concluded as 'speed acquisition method based on GPS or DGPS, speed acquisition method based on machine vision, speed acquisition method based on laser or doppler radar, speed acquisition based on wheel speed sensor'. The advantages and disadvantages of each method were analyzed. Based on the analysis of existing methods, the optimal method was summarized, which provided a theoretical basis for precision agricultural speed acquisition.
