Embodiment Construction
[0050] The specific technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.
[0051] The multi-spectral resolution of the Landsat 8 remote sensing image processed by the method of the present invention reaches 30 meters. In this embodiment, the image data of the first 7 bands are taken, which are respectively the aerosol band (0.43-0.45 μm), the blue band (0.45- 0.51 μm), green band (0.53-0.59 μm), red band (0.64-0.67 μm), near infrared band (0.85-0.88 μm), short infrared band 1 (1.57-1.65 μm), short infrared band 2 (2.11- 2.29μm), the image size is 256 rows × 256 columns, as attached figure 2 shown.
[0052] Such as figure 1 As shown, the specific steps of the raft type mariculture extraction method based on high-resolution remote sensing images of the present invention are as follows:
[0053] 1.1) Use the larger scale parameter S to segment the remote sensing image. The segmentation algorithm can use t...
