Abstract:
A method and apparatus for inspecting utility scale wind turbine generator blades from the ground includes a digital camera and an adjustable polarizing filter on a stable platform. The camera is used to record multiple digital images with varying polarization angles using an artificial polarized or polarized solar illumination to produce images with the same or similar registration but different polarization angles, followed by image processing using subtraction or absolute difference routines to yield high resolution, high contrast images with reduced glare and excellent surface definition over the field of view.

Claim (Index 7):
A method of remotely inspecting a stationary or rotating land or offshore wind turbine blade in situ, the wind turbine blade being illuminated by polarized solar or polarized artificial light, the method comprising:\n acquiring a first image of the wind turbine blade using a first digital visible light camera equipped with a first polarizer having a first polarization angle; simultaneously acquiring a second image of the wind turbine blade using a second digital visible light camera equipped with a second polarizer having a second polarization angle different from the first polarization angle; in an image processing computer, aligning the first and second images into registration with one another; and in the image processing computer, performing image subtraction or calculating an absolute difference of the first and second images to yield a final image of the wind turbine blade.
