📝 摘要(中文)
跨视角特征匹配旨在建立在大视角变化下图像之间的可靠对应关系。过去十年,该领域从任务特定模型演变为越来越统一和可推广的对应模型,最近的进展受到视觉基础模型(VFM)出现的推动。尽管取得了这些进展,现有研究在问题表述、模型架构、训练范式和评估协议上仍然高度多样化,导致难以获得统一的理解。本文提供了跨视角特征匹配的统一综述,介绍了一个涵盖特征提取、单类型特征匹配器、多类型特征匹配器、基于VFM的方法、训练策略和鲁棒估计的结构化分类法,提供了分析和比较的连贯框架。我们还审视了最近的进展,提炼出关键设计原则,并强调向统一和可推广的对应模型的转变。最后,讨论了开放挑战和未来方向,包括效率、极端条件下的鲁棒性和跨域泛化。

📄 摘要(原文)
Cross-view feature matching aims to establish reliable correspondences across images with large viewpoint variations. Over the past decade, the field has evolved from task-specific models toward increasingly unified and generalizable correspondence models, with recent progress further driven by the emergence of vision foundation models (VFMs). Despite these advances, existing studies remain highly diverse in their problem formulations, model architectures, training paradigms, and evaluation protocols, making it difficult to obtain a unified understanding of the field. In this survey, we present a unified review of cross-view feature matching. We first introduce a structured taxonomy covering feature extraction, single-type feature matcher, multi-type feature matcher, VFMs based methods, training strategy and robust estimation, providing a coherent framework for analysis and comparison. We further examine recent advances, distilling key design principles and highlighting the shift toward unified and generalizable correspondence models. We also provide a unified experimental benchmarking of representative state-of-the-art methods under consistent protocols, enabling fair and comprehensive performance comparisons. In addition, we discuss open challenges and future directions, including efficiency, robustness under extreme conditions, and cross-domain generalization. This survey aims to provide a comprehensive and structured reference for understanding the evolution, current landscape, and future development of cross-view feature matching in the era of vision foundation models.
