Embodiment Construction

[0035] Such as figure 1 A method for parking recognition of an agricultural machinery vehicle shown includes the following steps:

[0036] Step 1: Establish a central server, set up the Beidou satellite positioning device on the agricultural machinery, the central server communicates with the Beidou satellite positioning device through the Beidou module, and the central server collects the parking points of the agricultural machinery according to the Beidou satellite positioning device on the agricultural machinery, and sets these parking points as the anchor point;

[0037] Step 2: The central server preprocesses the positioning point, and the specific steps are as follows:

[0038] Step A1: According to the working time of the agricultural machinery, the area to which the agricultural machinery belongs and the maximum speed of the agricultural machinery's plowing operation, the activity area of ​​the agricultural machinery is determined;

[0039] Step A2: Set the anchor po...

Abstract

The invention discloses an agricultural machinery vehicle parking identification method, and belongs to the field of big data, the method comprises the steps of data preprocessing, aggregation point segmentation, aggregation point shape feature extraction, aggregation point speed feature extraction, aggregation point direction feature extraction, aggregation point density feature extraction and screening of aggregation points with semanteme of parking by combining all feature parameters. The problem of finding the agricultural machine parking point are found, parking points can be convenientlydeleted or not deleted when cultivated land area is calculated, and area calculation is more accurate is solved. Mathematical and kinematic characteristics of the divergence phenomenon are extracted,and a characteristic extraction algorithm, a classification algorithm, a clustering algorithm and a trajectory analysis algorithm are added, so that agricultural operation gathering points are clear,and the operation area calculation is more accurate.

Description

technical field [0001] The invention belongs to the technical field of big data, and in particular relates to a method for identifying parking of agricultural machinery vehicles. Background technique [0002] When calculating the arable land area of ​​agricultural machinery according to the operation path trajectory of agricultural machinery, it is necessary to monitor the movement trajectory of the agricultural machinery and calculate the area through the trajectory. However, when the agricultural machinery is working, it is inevitable that parking conditions will occur. These parking points The calculation of the area will cause errors in the calculation data. At this time, it is necessary to screen the parking spots of the agricultural machinery to determine whether to delete or not to delete the parking spots. How to accurately find out these parking spots becomes a must in the calculation of the area of ​​the agricultural machinery. solved problem. Contents of the inv...
