Abstract

A method for generating a photogrammetric corridor map from a set of input images by recovering a respective pose of each image, wherein a pose includes a position and an orientation information of the underlying camera, including steps of: a) receiving a set of input images, b) defining a working set, c) initializing an image cluster, d) further growing the image cluster: d1) selecting one image from the working set that features overlap with at least one image already in the cluster, e) continuing with step b) if there remain images in the working set; if not, f) generating and providing as output the corridor map using the recovered camera poses.
