LIDAR ALIGNMENT TOOL FOR ALIGNING A LIDAR SYSTEM WITH A ROTATION AXIS OF A ROTOR OF A WIND TURBINE

摘要

This invention relates to a method of aligning a LIDAR system with a rotation axis of a rotor of a wind turbine using a LIDAR alignment tool comprising at least a wind turbine alignment interface configured for aligning the LIDAR alignment tool with a rotation axis of a wind turbine, at least a LIDAR alignment interface configured for aligning the LIDAR alignment tool with a LIDAR system so that a laser beam pointing direction of a LIDAR system can be aligned with the LIDAR alignment tool, and the LIDAR alignment tool comprises a gyroscope configured for obtaining a substantially fixed spin axis, which LIDAR alignment tool is configured to record a spin axis direction of the fixed spin axis constituting the one to-one reference between the spin axis direction and each of the wind turbine alignment interface and the LIDAR alignment interface.
