Summary
[edit]DescriptionConstruyendo un modelo 3D una estela con un escáner.jpg |
Español: Para construir modelos 3D de objetos arqueológicos se usan escáneres que proyectan un patrón de luz y recogen sus deformaciones al moverse sobre la superficie. A partir de esas deformaciones se calcula la forma del objeto mientras simultáneamente se captura su color. La pieza en esta imagen es la llamada estela de Hernán Pérez (Extremadura), tallada sobre granito, de unos 85 cm de altura y datada en la primera mitad del II milenio a.C. Se expone en el Museo Arqueológico Nacional de España, en Madrid, con el número de referencia 1991/105/6 y se escaneó in situ. Tras ser escaneado en su totalidad, se realiza el procesamiento de reconstrucción de la "topografía" del objeto y de asignación de color. |
