Abstract
This disclosure relates to a device for optically measuring the curvature of a rotor blade () of a wind power plant (). The rotor blade is fixed at the blade root () to a rotor hub () or a rotor (). The device includes at least one light-emitting external marking () fixed to the rotor blade () at a distance from the blade root (), at least one camera () fixed to the rotor () for capturing the light () emitted from the external marking (). The device provides first location information as a function of the relative position of the camera () with respect to the external marking (). An evaluating device () is coupled to the camera (), and a position detection means detects the relative location of the camera () with respect to the blade root () and provides second location information as a function of said relative location. The evaluating device () determines at least one variable characterizing the curvature of the rotor blade () while evaluating the position information.
