Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0030] Such as figure 1 As shown, a remote sensing image change detection method includes the following steps:
[0031] Step 1. Input two multi-spectral remote sensing images of the same area and different time phases, which are respectively recorded as remote sensing image X and remote sensing image Y; the data source used in this embodiment is as figure 2 As shown, image (a) is the remote sensing image of a certain area taken by Landsat8 satellite in 2016, image (b) is the remote sensing image of the same area as image (a) taken by the satellite in 2018, image (a) Exactly the same area as image (b);
[0032] Step 2. Perform image registration on remote sensing image X and remote sensing image Y to obtain remote sensing image X and remote sensing image Y after image registration; wherein, image registration uses conventional methods in the...
