Embodiment Construction
[0055] The invention fully utilizes the multiple features of multi-source images to segment wharves and ships, utilizes the complementarity of different types of remote sensing images to obtain more target information, and improves the accuracy of segmenting wharves and ships.
[0056] Attached below Figure 1~7 The implementation steps of the present invention are further described in detail.
[0057] Step 1: Read in the multispectral, panchromatic and SAR images of docks and ships in the same area.
[0058] Step 2: Preprocess the multispectral, panchromatic and SAR images respectively. Perform preprocessing such as contrast enhancement on multispectral and panchromatic images, and perform morphological filtering preprocessing on SAR images.
[0059] Piers and ships have obvious color features in multi-spectral images, which are obviously different from the tonal features of water areas. It is easy to identify targets in the images, especially the color difference between w...
