Abstract

The invention provides an acquisition method and apparatus of the operation area of farm machinery. The acquisition method of the operation area of farm machinery includes the steps: receiving the farm machinery operation track data sent from a farm machinery positioning device; based on the operation speed, improving the neighborhood radius determination method of the dbscan clustering algorithm; utilizing the improved dbscan clustering algorithm to filter the road driving point and the field transition point in the farm machinery operation track data; according to the filtered farm machinery operation track data, determining the number of fields operated by the farm machinery; and utilizing the distance method to calculate the area of each field operated by the farm machinery. The acquisition method and apparatus of the operation area of farm machinery can adaptively determine the neighborhood radius according to the operation speed of farm machinery, can effectively segment the adjacent fields operated by the farm machinery, and can improve the accuracy and automation degree for acquisition of the operation area of the farm machinery.

Description

Technical field [0001] The invention relates to the technical field of agricultural applications, in particular to a method and device for obtaining the working area of ​​agricultural machinery. Background technique [0002] Although the relevant departments of our country have accurately drawn some farmland maps, these data are still difficult to use publicly due to the need for confidentiality and non-sharing of information. Therefore, in agricultural machinery operations, it is not possible to directly obtain agricultural machinery operating area. Moreover, due to the widespread existence of socialized agricultural machinery services, the ownership of land ownership, agricultural machinery ownership, and agricultural machinery operating services are not unified, leading to common problems such as cutting corners and artificially lowering the quality of operations. The use of state subsidies for substandard operations often occurs. How to monitor the working area of ​​agricult...
