Embodiment 1
[0022] Embodiment 1. A method for estimating forest aboveground biomass.
[0023] figure 1 It is a flow chart of the method for estimating forest aboveground biomass in an embodiment of the present invention.
[0024] exist figure 1 In step 1, read in a pair of polarimetric interferometric SAR (Synthetic Aperture Radar, synthetic aperture radar) images, and perform image preprocessing on the read in pair of polarimetric interferometric SAR images.
[0025] Specifically, a pair of polarization interference SAR images in this embodiment refers to a main image (the main image is a polarization SAR image) and an auxiliary image corresponding to the main image (the auxiliary image is also a polarization SAR image) ; for example, an example of the main image in an L-band pair of polarimetric SAR images is Figure 2a As shown, an example of the auxiliary image in the L-band pair of polarization interferometric SAR images is Figure 2b shown. That is to say, a pair of polarizatio...
Embodiment 2
[0120] Embodiment 2: A device for estimating forest aboveground biomass. The main structure of the device is as Figure 7 shown.
[0121] exist Figure 7 Among them, the forest aboveground biomass estimation device mainly includes: a preprocessing module 700, a vertical distribution module 710, a forest area module 720, a stand module 730, a parameterization module 740, a model building module 750 and a forest aboveground biomass estimation module 760 .
