Abstract

Se proporciona un sistema y un método para la medición 3D de la forma de objetos materiales que utilizan la triangulación de luz estructurada sin contacto. El sistema incluye un proyector de luz para proyectar un patrón de luz estructurada en la superficie de cualquier objeto y una cámara para capturar una imagen del patrón de luz estructurada que actúa en la superficie del objeto. El sistema además incluye un dispositivo de cómputo para determinar la medición 3D de la forma de superficie del objeto iluminado a través de un algoritmo de triangulación empleado con base en una correspondencia calculada entre la luz estructurada proyectada y la imagen capturada. La luz estructurada incluye elementos codificados que yacen dentro de los planos que pasan a través de los vértices de las áreas de proyección central del proyector y la cámara, que también pasan a través del espacio del objeto que se mide.
