[0002] In my country, the tobacco industry has the function of accelerating capital accumulation and increasing the country's fiscal capacity. my country is a major tobacco producer in the world, and the tobacco industry occupies an important position in my country's national economy. In the process of tobacco production, tobacco leaf picking is a basic work, and whether it can be picked in time will greatly affect the quality of tobacco leaves. my country's tobacco planting area is large, and the terrain is undulating and varied, with different landforms such as hills, mountains, and plains. For tobacco leaves planted in hilly and mountainous areas, large tobacco machines cannot enter the operation, and the tobacco leaf harvesting process mostly adopts manual harvesting. Although small-scale manual assisted harvesting and transportation machines have better adaptability in the field and tobacco leaf harvesting is relatively complete, they still have not gotten rid of the constraints of labor, with large labor input, high labor intensity, and relatively low harvesting efficiency. Failure to harvest tobacco leaves in time will cause certain economic losses.
