The invention relates to an agricultural
machine operation area optimization calculation method for efficiently and intelligently identifying and eliminating Beidou
satellite positioning driving track drift points, and aims to solve the problems of operation track
distortion and virtual height of area caused by positioning drift point interference generated in a parking state of an agricultural
machine. According to the method, a set of multi-stage intelligent
trajectory analysis and cleaning
algorithm is constructed, drifting data is preliminarily eliminated by using static point clustering and speed
anomaly detection means, and adaptive judgment and
elimination of direction anomaly line segments are realized through an intelligent recognition mechanism combining direction clustering and a shallow neural network. And finally, an Alpha Shapes space geometry
algorithm is adopted to accurately extract the boundary of the operation area, and area calculation is completed. The whole process does not need additional sensor input, has the advantages of high
automation, high learning ability, high adaptability and the like, remarkably improves the reliability of the operation track of the agricultural
machine and the calculation precision of the operation area, and is particularly suitable for agricultural operation monitoring and management under complex terrains and variable working conditions.
