Resumen. En este trabajo se propone una metodología mediante el uso de técnicas basadas en proyección de luz estructurada, permitiendo la medición de puntos 3D pertenecientes al objeto bajo prueba. El sistema metrológico se calibra a partir de un conjunto de imágenes que presentan un patrón de desplazamiento. El cálculo de profundidad se realiza utilizando un ajuste por mínimo cuadrados en el que se calibra por medio de una serie de imágenes referentes a planos. Siendo los primeros dos los correspondientes a anchura y altura, el tercero es el que determinara la profundidad.Palabras clave: reconstrucción tridimensional, mínimos cuadrados, luz estructurada, cambio de fase, flood fill.Abstract. In this work a methodology is proposed through the use of techniques based on structured light projection, allowing the measurement of 3D points belonging to the object under test. The metrological system is calibrated from a set of images that have a displacement pattern. The depth calculation is carried out using a minimum square adjustment in which it is calibrated by means of a series of images referring to planes. The first two being those corresponding to width and height, the third is the one that determines the depth.
