Farmland soil monitoring method and system based on multi-sensor fusion

The invention discloses a farmland soil monitoring method and system based on multi-sensor fusion. The method comprises the steps of obtaining soil moisture data collected by a soil moisture sensor in a collection period; obtaining vegetation soil spectral data collected by a multi-spectral sensor carried by the unmanned aerial vehicle; acquiring farmland environment data acquired by a meteorological sensor; performing data preprocessing on the acquired soil moisture data, the vegetation soil spectral data and the farmland environment data, performing data fusion on the preprocessed soil moisture data, the vegetation soil spectral data and the farmland environment data, and analyzing a relationship among the soil moisture data, the vegetation soil spectral data and the farmland environment data; and associating the preprocessed data with the geographic coordinates of the data source positions, and drawing the data on an electronic map according to the associated geographic coordinates of the data source posit
