The objective of the paper is to apply the reverse engineering in the mechanical field to reconstruct the geometry of two types of model turbine blade: axial blade and Pelton bucket. To generate the point clouds, the geometry of the blades was scanned by laser and digital photogrammetry. The Creaform HandySCAN 700 laser scanner and VXelements software were used to get the point cloud of the blades. For digital photogrammetry the NIKON D610 photo device and Agisoft Photoscan software were used to get the point cloud of the blades. Finally, the point clouds generated were compared in GOM Inspect software to highlight the deviations between them.
