Un método para recuperar la forma de los objetos, consiste en la proyección de luz estructurada, la cual básicamente consiste en hacer incidir un haz de luz sobre el objeto y medir la distorsión que este sufre, la cual es proporcional a la forma del objeto, que fue capturado a través de una imagen digital [15, 16]. Las imágenes digitales contienen una gran cantidad de información, la cual necesita ser procesada con el objetivo de extraer aquellas zonas relevantes para un determinado fin. En la teoría de métodos numéricos destacan diversas técnicas de interpolación, cuya finalidad es establecer aproximaciones que sean de utilidad en aquello que se desea estudiar o analizar. Una de ellas es Bezier cuyas características geométricas y analíticas de dichos polinomios trae como consecuencia la pertinencia de su empleo. En este trabajo se aplican las áreas de estudio mencionadas en párrafos anteriores con la finalidad de recuperar la forma del objeto sobre el cual incide el haz de luz estructurada, la extracción de puntos de interés usando visión por computadora y aplicando polinomios de Bézier para la obtención de la forma.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: The recovery of the shape of the objects is of utmost importance in order to have numerical models, for example, in industry for the generation of pieces, in health in prosthesis construction, in archeology for the conservation of the unique pieces [24-26]. A method to recover the shape of objects consists of the projection of structured light, which basically consists of making a beam of light fall on the object and measuring the distortion it suffers, which is proportional to the shape of the object, which was captured through a digital image [15, 16]. Digital images contain a large amount of information, which needs to be processed in order to extract those relevant areas for a specific purpose. In the theory of numerical methods, various interpolation techniques stand out, the purpose of which is to establish approximations that are useful in what you want to study or analyze. One of them is Bezier, whose geometric and analytical characteristics of these polynomials result in the relevance of their use. In this work, the study areas mentioned in previous paragraphs are applied in order to recover the shape of the object on which the structured light beam falls, the extraction of points of interest using computing vision and applying Bezier polynomials to obtain shape.]]></p></abstract>
