Reconstrucción 3D a través de un sistema videogramétrico basado en la utilización de VisualSLAM y un procedimiento específico de selección de imágenes

Resumo

In recent years, 3d scanners have proliferated for applications in engineering, architecture and archeology, among others. This doctoral thesis tries to create a new measurement system based on videogrammetry, which consists of three main elements: A real-time user assistance system, an image selection procedure and, a 3d reconstruction from the selected images. To achive this, two prototypes have been designed and the results were evaluated by comparing them with a photogrammetric software (Agisoft Metashape) and a commercial laser scanner (Faro Focus x330). The results show an improvement in acquisition times compared to traditional photogrammetry and LS. On the other hand, it has important similarities in geometric accuracy and textures quality respect to the laser scanner. Finally, it applies this technology in the field of medicine through the 3d reconstruction of the temporomandibular joint, using the arthroscope assuming a relevant innovation, being one of the first 3d reconstructions of this joint through this methodology.
