The reverse engineering of a blade runner geometry through photogrammetry

Abstract

Abstract. The paper illustrates the reverse engineering process of a blade, from a Kaplan runner with a diameter of 5400 mm, using the following software packages: Agisoft Photoscan and Geomagic Design X (formerly Rapidform XOR); the next step was to generate the solid geometry of the blade using the SolidWorks software. The last step was to compare, using GOM Inspect software, the geometry of the designed blade with the corresponding geometry obtained using Photogrammetry and finally answer the question if this technique can be used in the mechanical field to get a precise 3D reconstruction of large objects with complex geometries.
