Reconstrução tridimensional em nuvem de pontos utilizando o método SIFT e técnicas de estruturação por movimento.

Abstract

With the advance of technology, the fields of research, industry and entertainment have been focusing on software development and its integration with the general public. Some of this researches became promissing like Image Processing, Computer Vision and Three Dimensional Modeling. This last one being started on the 70’s, had an enormous advance thanks to the hardware improvement along the years. Due the need of the public to be immersed in this technology, this work brings some 3D modeling concepts and techniques for 3D reconstruction. It will be seen some concepts about camera and how the image capturing works, some image processing concepts like the SIFT algorithm for feature extraction, and a set of techniques about 3D reconstruction based on photos, called Structure from Motion. Finally, will be presented an smartphone application that uses all theses concepts to do a 3D reconstruction.
