| titleOfInvention | A water body identification method and related device |
| abstract | The present application discloses a water body identification method and a related device, which are applied to at least one of the fields of maps, automatic driving, and intelligent transportation. Obtain the target image of the target geographic area, construct the difference index corresponding to the various types of ground objects included in the target image, and perform image enhancement on the target image based on the difference index, and obtain the first color space of the target image in the first color space. A color image. Convert the first color image into a second color image in a second color space, the second color space is a color space with hue, saturation and brightness as the basic feature components, which is in line with human visual perception, so that different types of mixed pixels are mixed. Land features differences are more clearly reflected. Pixels whose pixel values satisfy the first preset conditions corresponding to the basic feature components are extracted from the second color image to form the first water body recognition result, and the target water body recognition result is determined according to the first water body recognition result, so as to improve the water body recognition, especially the small water body recognition results. Accuracy of water body identification. |
