| titleOfInvention | Floating raft culture area extraction method based on land resource satellite images |
| abstract | The invention relates to a floating raft culture area extraction method based on land resource satellite images, which is characterized by comprising the following steps of: 1) on the basis of remote sensing image segmentation, extracting a water body area in the remote sensing image by using an NDWI index; 2) on the basis of small-scale segmentation of a water body region, potential breeding region P is extracted by using NDVI (Newcastle disease Virus) visual salient features 1 (ii) a 3) Calculating potential breeding area P 1 Edge overlap of middle plaque, pair P 1 Further screening to obtain more accurate potential breeding area P 2 (ii) a 4) Calculating potential breeding area P 2 Relative width of middle plaque, pair P 2 And further screening to obtain a final extraction result. On the basis of the NDVI visual salient features, the method utilizes the characteristic of salient edge features of the culture area and introduces the concept of edge overlapping degree, thereby realizing high-precision extraction of the raft culture area in the land resource satellite image. |
