Abstract: The present disclosure relates to a control system for a wind turbine that is configured to: obtain a 3-dimensional image of at least a portion of a wind turbine blade; recognise a target feature of the wind turbine blade in the obtained image and identify the position of the target feature; and monitor the state of the wind turbine blade and/or control operation of at least one blade in dependence on the identified position of the feature.

Abstract: According to an embodiment of the present invention there is provided an apparatus for monitoring an ambient environment of a wind turbine. The apparatus comprises a cooling system comprising first and second heat exchangers, and a fluid circuit arranged to enable coolant to flow between the first and second heat exchangers. The apparatus further comprises a processor configured to: monitor one or more operational parameters of the cooling system; measure an efficiency of the cooling system based on the monitored one or more operational parameters; and calculate a liquid water content of the ambient environment based on the measured efficiency of the cooling system.

Abstract: The present disclosure relates to a system for determining at least one blade state parameter of a wind turbine blade, wherein the system is configured to: obtain blade data relating to the wind turbine blade from a sensor system associated with the wind turbine blade; compare at least one reference model of at least a portion of the wind turbine blade with the blade data; identify a reference model in dependence on the comparison; and determine at least one blade state parameter in dependence on the identified reference model. The blade data may take the form of an image, for example a 3-dimensional measurement such as a point cloud representing at least a portion of the blade.
