Embodiment Construction
[0026] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] A kind of remote sensing time series data fitting method based on Gaussian mixture model of the present invention, such as figure 1 shown, including the following steps:
[0028] Step 1: Obtain remote sensing time series data;
[0029] Prepare multiple remote sensing images of the same area, such as MODIS remote sensing images of 45 scenes with a two-year span at an interval of 16 days. Sure figure 2 The central mark point in the central box is the forest sampling point of this embodiment, and its geographical location is: N30°15′18.95″ north latitude, E120°06′54.32″ east longitude. Read the NDVI values of the 45 remote sensing images in sequence, and organize them into NDVI time-series data in chronological order, as shown in Table 1.
