Sistema de escaneo tridimensional multipropósito

Abstract

The technology of three-dimensional scanning has revolutionized the world with its contribution in research in different fields such as medicine, archeology, architecture, among others, generating digital models of real-life objects and allowing to perform processes of analysis and study without disturbing the integrity of it. Although at present different scanners have been developed, each time with a lower cost, access to this technology is very limited in our environment. In this work, an economic system of three-dimensional scanning (3D) was developed that allows obtaining information of the physical structure of a specific object from which a digital model is generated. This system operates by projecting a beam of laser light in the form of a line on the object, while rotating on its own axis (z-axis), the beam of light creates a profile of the object, which is captured by high-definition video (HD) for a camera. Through the digital processing of the captured images obtains the vertices of the object and the three-dimensional model is constructed. To carry out this task, the 3D scanner is made up of a set of hardware and software elements such as: the Arduino platform, which allows the control of the scanning hardware, and software developed in C ++ that implements the OpenCv libraries and OpenGl, allows the realization of image processing and analysis tasks. This device will allow the students of the Lumen Gentium Catholic University Foundation to scan real-life objects and generate three-dimensional computer models of them, facilitating the development of different research processes.
