Agricultural machinery operation area measuring and calculating method based on positioning drift measuring and calculating model

Abstract

An agricultural machinery operation area measuring and calculating method based on a positioning drift measuring and calculating model comprises the following steps: 1, performing agricultural machinery operation track point acquisition and preprocessing: preprocessing sensor data, filtering agricultural machinery operation state information, and constructing a track point time sequence conformingto an operation state; 2, constructing a positioning track and an operation track; establishing a polygon according to the operation width; 3, calculating the coverage area of the operation track: calculating the track area, the coverage area and the blank area of the operation track from different angles; 4, constructing a positioning drift measurement and calculation model by utilizing the extracted core features, and training a sample to learn model parameters; and 5, agricultural machinery operation area measurement and calculation: inputting the operation track and the operation area tobe calculated into the positioning drift measurement and calculation model to obtain an accurate agricultural machinery operation area. The problem that when multiple operation types exist in the farming process of the agricultural machine, overlapping areas and non-operation areas are generated, the calculation precision of the operation area of the agricultural machine is not high is solved.

Description

technical field [0001] The invention relates to a method for measuring and calculating the working area of ​​agricultural machinery based on a positioning drift measuring and calculating model. Background technique [0002] The subsoiling and plowing operations of agricultural machinery are of great significance to the realization of soil moisture conservation and improvement of farmland compaction. Installing geographic information system, space positioning system and other digital technology navigation devices on agricultural machinery, combined with the background service system mode, can meet the remote monitoring and management needs of agricultural machinery for subsoiling and plowing and land preparation operations, and realize precise operations of agricultural production, plowing and harvesting. The new agricultural machinery management and market-oriented service model is becoming more and more mature. Both the supply and demand sides require agricultural machinery...
