Embodiment 1
[0058] A method for image damage detection and location of wind turbine blades, based on a deep convolutional neural network, including two processes of model training and damage detection and location:
[0059] Among them, such as figure 1 As shown, model training includes the following steps:
[0060] In step S101, a surveillance camera is used to collect images of the surface of the wind turbine blade. The image data used in the embodiment of the present invention all come from a wind farm in eastern China, including a total of 725 surface images of wind turbine blades captured by high-resolution cameras. figure 2 It is a sample of the surface image of the wind turbine blade collected at the wind farm site.
[0061] In step S102, the position and type information of the damage is manually marked on the image of the wind turbine blade, and the image samples containing the damaged area (positive samples) and the image samples of the normal blade surface (negative samples) ...
