Abstract

The invention provides a farmland operation area metering method and device. The method comprises the steps that a movement trajectory of an agricultural machine is obtained on the basis of vehicle-mounted GPS data of the agricultural machine, and the movement trajectory is divided into a plurality of element line segments according to track points on the movement trajectory; for each of the element line segments, an external rectangle of each element line segment is generated; for all track points except the starting point of the first element line segment and the ending point of the last element line segment, a buffer area of each track point is generated; the external rectangle of each element line segment is combined with the buffer area of each track point to obtain the operation track buffer area of the agricultural machine, and the operation area is calculated according to the operation track buffer area of the agricultural machine. According to the method, calculation results meet actual conditions of the operation of the agricultural machine, and measurement errors can meet the requirement for measuring the precision of the operation area of the agricultural machine.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery operations, and more specifically, to a method and device for measuring farmland operation area. Background technique [0002] With the rise of labor costs and the expansion of agricultural operations under land transfer, the urgent demand for mechanization and even mechanized operation services in agricultural production has become increasingly prominent. The operating area is the core indicator of planting and production, and it is the basis for the settlement of expenses between the supply and demand sides under the background of agricultural machinery market services. In addition, the operating area is also the basis for the settlement of agricultural policy subsidies. Especially in recent years, with the rapid development of agricultural machinery supervision methods and the agricultural market system, traditional agricultural machinery purchase subsidies have gradually been tr...
