Lodging crop monitoring method, electronic equipment and readable storage medium

The invention provides a lodging crop monitoring method. The lodging crop monitoring method comprises the following steps: acquiring preprocessed field survey sample data, optical remote sensing data and fully polarized SAR satellite image data; establishing lodging sample set data and non-lodging sample set data; all polarization parameters of the farmland plot in the operation area are extracted, and the lodging proportion of crops under each grid is counted; probability density distribution information under different polarization parameters is established, and optimal polarization parameters are screened out by using a multiple linear regression model and a back-off method; constructing a parameter weight evaluation index by using the probability density distribution information, and determining the weight of the preferred polarization parameter; and adopting a Gaussian mixture model to obtain probability space distribution information of the lodging crops in the operation area according to all the prefer
