Abstract

The invention relates to an agricultural machinery operation and migration separation method based on an adjacent track mapping coverage rate. The method comprises the following steps: acquiring track point data corresponding to the running of an agricultural machinery within a set time; for each track point in the track point data, determining a coverage radius corresponding to the track point, and determining all adjacent track points of the track point according to the coverage radius; when the number of all adjacent track points of the track points is smaller than a set value, judging that the track points are migration track points; when the number of all the adjacent track points of the track points is not smaller than a set value, the coverage rate of the coverage area of all the adjacent track points of the track points is determined according to the number of all the adjacent track points of the track points, and whether the track points are migration track points or operation track points is judged according to the coverage rate. According to the method, data labeling is not needed, operation is simple and efficient, interpretability is high, and the accuracy is improved through adjacent track mapping coverage rate analysis.
