Abstract

One of the most important components of a wind turbine are the blades, the evaluation of their manufacturing quality and aerodynamic capabilities can be very costly, for this reason a 3D reconstruction by stereo vision is proposed. This technique consists of projecting a laser line in each face of the blade. Using a linear stage, two cameras will scan simultaneously, considering bidirectional disparities and feature correspondences between the two pictures. Two symmetric airfoils of the NACA 0012 family are evaluated. The expected precision is 0.1mm.
