Embodiment Construction
[0027] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0028] A method for automatically extracting multi-cropping index of arable land of the present invention, the method is based on time-series remote sensing data, specifically comprises the following steps,
[0029] Step S1: Obtain the wavelet coefficient spectrum decomposed by continuous wavelet based on the intra-year time series signal;
[0030] Step S2: From the wavelet coefficient spectrum obtained by continuous wavelet decomposition, extract a series of wavelet coefficient contour lines with positive values;
[0031] Step S3: Count whether each wavelet coefficient contour line is closed in turn, and store its quantity in the eigenvalue variable N one by one;
[0032] Step S4: According to the maximum value of the characteristic variable N and whether multiple contours overlap and cover the scale interval, establish the ripening dis...
