We propose a new detector-free SfM framework to draw benefits from the recent success of detector-free matchers to avoid the early determination of keypoints, while solving the multi-view inconsistency issue of detector-free matchers. Specifically, our framework first reconstructs a coarse SfM ...

与它们不同的是,我们的无探测器SfM框架以粗到细的方式可以恢复高精度的姿态和点云。 Multi-View Refinement. 精确的多视图对应是在SfM中恢复精确的点云和相机姿态的关键。技术上的挑战是,特征点的透视检测不能保证它们在多个视图之间的几何一致性。为了解决这一问题,以往的一些方法采用流[14]或密集特征[27]进行...
leading to improved performance and faster computation times. In this review, we explore the evolution of local feature matching from detector-based to detector-free methods, discussing the advantages and disadvantages of each approach and highlighting the recent advancements in the field. We also disc...
code:LoFTR: Detector-Free Local Feature Matching with Transformers 1. Introduction 图像之间的局部特征匹配是许多3D计算机视觉任务的基石,包括运动结构(SfM)、同时定位和映射(SLAM)、视觉定位等。给定要匹配的两幅图像,大多数现有的匹配方法包括三个独立的阶段:特征检测、特征描述和特征匹配。在检测阶段,首先从每个图...
We also collect a texture-poor SfM dataset to demonstrate the capa-bility of our framework to reconstruct texture-poor scenes. Based on this framework, we take the first place in Image Matching Challenge 2023 [9]. Project page: https://zju3dv.github.io/DetectorFreeSfM/. 展开 关键词:...
