A method and system for measuring the water surface width of the whole water area of a river |
| abstract |
The invention discloses a method and a system for measuring the water surface width of the whole water area of a river. The method includes: acquiring a river channel remote sensing image; determining a set of multiple straight lines of target points in the river channel in the river channel remote sensing image as a target straight line set; The line pixel coordinate set of each line; based on the line pixel coordinate set, calculate the pixel coordinates of the left intersection and the right intersection of each line in the target line set; calculate the pixel coordinates of any left intersection corresponding to each line and any The pixel point distance between the pixel coordinates of a right intersection, and the minimum pixel point distance is determined as the straight line distance between the two sides of the corresponding line; width. The invention realizes high-efficiency and high-precision measurement and calculation of large-scale and dynamic river width. |
