Abstract

The invention describes a laser projector assembly (1) for use in a wind turbine rotor blade manufacturing facility (3), comprising a number of laser projector units (10), wherein each laser projector unit (10) comprises a positioning means (13) for positioning the laser projector unit (10) above a selected rotor blade mould (2), and a laser projector (12) configured to project layup guides (12G) into that mould (2) during a manual layup procedure; an imaging arrangement (11) adapted to capture images (110) of that mould (2); a machine learning algorithm (18) trained to determine coordinates of a feature (2M, 12P) in an image (110); and a calibration module (16) configured to calibrate a laser projector (12) to that mould (2) prior to the manual layup procedure on the basis of an output (180) of the machine learning algorithm (18). The invention further describes a method of manufacturing a wind turbine rotor blade (4) using such a laser projector assembly (1), a machine-learning algorithm (18) for use in such a laser projector assembly (1), and a method of training such a machine-learning algorithm.
