A method and device for determining a tower clearance of a wind turbine. The method includes: acquiring an image of a wind turbine in operation (S), the image comprising the tips of blades () and a tower () of the wind turbine; determining the positions of the tips of the blades () of the wind turbine in the image acquired (S); identifying the edges of the tower () in the image acquired (); and calculating, on the basis of the positions of the tips of the blades () and the edges of the tower () that have been determined, the distance from the tips () of the blades () to the edges of the tower () to acquire a tower clearance (S).

Method and device for determining tower clearance for wind turbine

A method and apparatus for monitoring formation of ice on a wind turbine blade are provided. The method includes: capturing an image of the blade through a camera; detecting a region of the blade from the captured image; clearing image information of a background region from the captured image, which is in the captured image except for the region of the blade, to obtain a blade image; and inputting the obtained blade image into a recognition model of ice on a blade obtained by training on a sample set, to determine whether ice is on the captured blade, wherein the sample set comprises a plurality of blade images indicating that ice is on blades.
