Abstract
This paper presents the design and implementation of a bifocal scanner for 3D image reconstruction from 2D images. The scanner consists of a bifocal rotating base composed of 2 web cameras and a laser, which will capture multiple images from different angles, to be processed and digitized. At a later stage, computer vision techniques will be applied to eliminate noise, adjust brightness, highlight edges, enhance the image in grayscale and select the region of interest. The selection process of the region of interest will indicate the values of the position in X, Y, Z coordinates, this being the point cloud to be found. This allows 3D reconstruction from a 2D image through stereoscopic vision, since its analysis is performed by means of slices or sections of the captured images.
