Reconstruction of 3d objects with axial symmetry from laser triangulation This article describes the 3D reconstruction of an object that possesses axial symmetry from the laser triangulation method; the system allows obtaining the shape and dimensions of an object by directional light projection in structured form and controlled rotation of the object. The system consists of a lighting stage through the projection of a laser line, a system of acquisition through the use of a webcam and the design of a platform that is responsible for the rotation controlled by a motor coupled to a box speed reducer. The software application allows synchronizing the system through the USB port, to finally perform the image processing and the display of the results obtained in a graphical interface. Experimental design considerations and their limitations as minimum resolution, accuracy of measures are detailed in this article. Key words: 3D Reconstruction, laser triangulation, optical metrology, axial simmetry.
