| titleOfInvention | A method for extracting linear shape of lake ice surface |
| abstract | The invention discloses a method for extracting a linear shape of a lake ice surface, comprising the following steps: the first step: selecting an ice surface image and performing image preprocessing; the second step: generating a single-band image and its binarized image; and the third step : Obtain the linear shape of the internal network of the surface morphology of the lake ice; Step 4: Remove the edge of the network structure; Step 5: Determine and extract the maximum connected domain contour of the internal network structure; Step 6: Determine the shortest path as the surface of the lake ice The length of the linear shape; Step 7: Calculate the angle of the linear shape of the lake ice surface. The invention uses spatial filtering, fractal theory, edge detection and other methods to build a remote sensing information extraction method for the linear shape of the lake ice surface, and proposes a quantitative index and a calculation method. The translated results have a high degree of consistency, high reliability, and can effectively extract the linear morphology information of the lake ice surface. |
