Unique recovery challenges arise from critical configurations in three projective views.
Samenvatting
The content discusses critical configurations in structure from motion problems, focusing on three projective views. It explains how unique recovery can be impossible in certain cases due to critical configurations. The article delves into the algebraic approach to studying these configurations, highlighting the intersection of quadric surfaces. It corrects an error in a published paper regarding critical configurations. The study classifies critical configurations for three projective cameras, emphasizing the intersection of quadrics. The article also touches on the implications of critical configurations in practical applications.
The structure of the content is as follows:
Introduction to structure from motion problems in computer vision.
Background on cameras, projections, and critical configurations.
Approach to finding critical configurations for three projective cameras.
Key results from the two-view case.
Preliminaries for the three-view case, discussing compatible triples of quadrics.
