摘要

本文论证了欧几里得运动结构(SFM)中存在一种通用的近似模糊性，该模糊性适用于深度变化较大的场景。在投影SFM中不存在歧义，但最大似然重建更有可能偶尔出现非常大的误差。该分析给出了与Jepson/Heeger/Maybank分析的互补域上的最小二乘误差曲面的半定量表征。

A new structure-from-motion ambiguity

This paper demonstrates the existence of a generic approximate ambiguity in Euclidean structure from motion (SFM) which applies to scenes with large depth variation. In projective SFM the ambiguity is absent, but the maximum-likelihood reconstruction is more likely to have occasional very large errors. The analysis gives a semi-quantitative characterization of the least-squares error surface over a domain complementary to that analyzed by Jepson/Heeger/Maybank.
