System and method for inspection of a wind turbine blade shell part

A method for inspecting a wind turbine blade part for defects, during manufacturing of the wind turbine blade part, wherein the wind turbine blade part extends in a longitudinal direction, and wherein the method comprises the steps of:

• providing a mould for manufacturing the wind turbine blade part with the blade part arranged in the mould;
• conveying at least a first image capturing device and a second image capturing device along the mould for manufacturing the wind turbine blade part using conveying means arranged on rails, wherein the first image capturing device is a thermographic image capturing device or an infrared camera, and wherein the second image capturing device is an optical camera;
• capturing a plurality of acquired images comprising first images of parts of the wind turbine blade part along the wind turbine blade part using the at least first image capturing device and second images of parts of the wind turbine blade part along the wind turbine blade part from the second image capturing device;
• image processing the plurality of acquired images to identify whether any of the plurality of acquired images includes an anomaly;
• and
• in accordance with identifying an anomaly, determining whether the anomaly relates to a defect in the wind turbine blade part.
