One-shot pattern projection for dense and accurate 3D reconstruction in structured light

This thesis focuses on the problem of 3D acquisition using coded structured light (CSL). In CSL, a projected pattern impinges artificial texture onto the object surface, increasing the number of correspondences in the retrieved image. Finally, 3D acquisition is pursued by triangulation. An active re...

En LE se proyecta un patrón en la superficie del objecto, a fin de incrementar la textura y el número de correspondencias con la imagen capturada, de la que se extrae la información 3D. Actualmente se trabaja en soluciones de LE para entornos moviles. La tesis presenta un compendio de las principales tecnicas en LE. Además, se estudian en detalles las dos propuestas de análisis frecuencial, proponiendo un algoritmo para el análisis del patrón capturado. Con ésto, se propone un método de un único patrón proyectado, obteniendo reconstrucción densa. La técnica se basa en WFT combinado con codificación DeBruijn. Los resultados muestran niveles de precisión comparables con otras técnicas DeBruijn, pero obteniendo reconstrucción densa. Finalmente, se estudia el problema de registro de reconstrucciones LE.Universitat de GironaSalvi, JoaquimUniversitat de Girona.
