Abstract

Abstract: Structure from motion is a computer vision problem that seeks obtain tridimentional scenes from a set of images shot from different points of view without having any previously camera configuration knowledge. The main approach consists in building a base reconstruction with two images, followed up by insertion of images one by one until the complete reconstruction. In spite of it’s robustness, there are cases that it’s not possible to make the two-view camera initialization leaving SfM systems not conclude the reconstruction process. Recently it is used three image as geometric base that shows bigger robustness potential by providing better reliability in getting correspondences and cameras being proposed as an alternative when two-view initialization fails. Only recently pratical ones could being made due the improvement of solver thechnnieques. These improvements made relative camera pose estimation more robust and efficient by using three oriented SIFT features. This article exposes the recent advances in trinocular geometry into the open source software openMVG alongside provided experimental results showing it’s practical robustness.
