Scale ambiguity in structure from motion
Résumé
This video illustrates the well-known scale ambiguity in estimating camera motion and 3D scene structure for central cameras (here, perspective cameras).
More information is provided in my chapter “Image Geometry” in the book “Omnidirectional Vision: From Theory to Applications”, edited by Pascal Vasseur and Fabio Morbidi, to be published by ISTE Science Publishing in 2022.
