Kind Code:
A1
Abstract:
Disclosed are a method, device and system for correcting installation errors of a wind vane (11). The method for correcting installation errors of a wind vane comprises: obtaining images of unit blades (7) and an electric generator outer rotor (S101); obtaining contours of the unit blades (7) and the contour of the electric generator outer rotor from the images of the unit blades (7) and the electric generator outer rotor (S102); calculating a unit center line (12) according to the contour of the electric generator outer rotor and the contours of two blades of the unit blades (7) (S103); obtaining a point of intersection of the unit center line and the contour of the electric generator outer rotor as a first point of intersection (S104); obtaining an orientating face of a wind vane (11) (S105); determining whether the wind vane (11) is aligned with the unit center line (12) according to the unit center line and the orientating face of the wind vane (11) (S106); and if the wind vane (11) is not aligned with the unit center line (12), calculating a deviation angle between the wind vane (11) and the unit center line (12) according to the orientating face of the wind vane (11) and the first point of intersection, and correcting the orientation of the wind vane (11) according to the deviation angle between the wind vane (11) and the unit center line (12) (S107).
