Summary: | Automatic system for reverse engineering in CAD environments and the objective evaluation of the colour. The system which is the subject of the present invention makes it possible (i) to measure the geometric and chromatic information of parts, (ii) to construct a geometric representation thereof suitable for being input and handled efficiently in computer-aided design (CAD) environments and, in the case of homogeneous parts, (iii) to quantify their chromatic behaviour objectively. The functioning of the invention is entirely automatic; the operator's role is reduced to locating the parts on the measurements platform, to defining the sequence of positions to be investigated and to running the various processes in the desired order (either directly or via a master process). Basically, the system comprises one or more image- acquisition devices 8, 9, the appropriate image digitising and storage equipment 2, 3, a positioning system 11, 12, 13, 14 with the corresponding control equipment 5 for controlled movement of the parts 10, a structured light projector 6, a projector of light which does not need to be structured 7, and computing equipment 1 equipped with the software necessary for the operation of the system 4. The physical location of all these components is arbitrary.
El sistema objeto de la presente invención permite (i) medir la información geométrica y cromática de piezas, (ii) construir una representación geométrica de las mismas adecuada para su introducción y manejo eficiente en entornos CAD (Computer Aided Design) y, en el caso de piezas homogéneas, (iii) cuantificar de forma objetiva su comportamiento cromático. El funcionamiento de la invención es enteramente automático: la misión del operador se reduce a ubicar las piezas en la plataforma de medida, a definir la secuencia de posiciones a estudiar y a lanzar los distintos procedimientos en el orden deseado (bien directamente o a través de un procedimiento maestro). Básicamente el sistema comprende uno o varios equipos de captación de imágenes (8) (9), los oportunos equipos de digitalización y almacenamiento (2) (3) de imágenes, un sistema posicionador (11) (12) (13) (14) con el correspondiente equipo de control (5) para el movimiento controlado de las piezas (10), un proyector de luz estructurado (6), un proyector de luz que no necesita ser estructurado (7), y un equipo informático de computación (1) dotado del software, necesario para el funcionamiento del sistema (4). La ubicación física de todos estos componentes es arbitraria. |
