2018 arXiv   pre-print
Structure from Motion or the sparse 3D reconstruction out of individual photos is a long studied topic in computer vision.  ...  The pipeline is able to recover from failed reconstructions in early stages, avoids to take binding decisions, delivers a progressive output and yet maintains the capabilities of existing pipelines.  ...  The field of Structure from Motion (SfM) deals with the intrinsic and extrinsic calibration of sets of images and recovers a sparse 3D structure of the scene at the same time.  ...
