让模糊影像也能精准建图,自动调节计算量。

Unblur-SLAM: Dense Neural SLAM for Blurry Inputs

  • 先用前馈网络去模糊,再优化位姿与深度
  • 模糊严重时直接建模多子帧,还原清晰细节
  • 适配运动/散焦模糊,适合低质量视频建图

我们提出Unblur-SLAM,一种用于从模糊图像输入中实现清晰三维重建的新型RGB SLAM流程。与以往工作不同,本方法能处理多种模糊类型,并在同时存在运动模糊和散焦模糊的情况下达到当前最佳性能。此外,系统根据输入图像的模糊程度动态调整计算开销。第一阶段使用前馈图像去模糊模型,我们提出了合适的训练方案,以提升跟踪与建图模块表现。成功去模糊的帧通过局部-全局多视图优化及回环闭合获得精修位姿与深度;未能成功去模糊的帧则直接通过全局3DGS表示与附加模糊网络建模多个模糊子帧,并在3D空间中模拟模糊形成过程,从而学习到清晰细节与精修子帧位姿。在多个真实世界数据集上的实验表明,该方法在位姿估计与几何纹理的清晰重建方面均实现稳定提升。

原文摘要 · Abstract (English)

We propose Unblur-SLAM, a novel RGB SLAM pipeline for sharp 3D reconstruction from blurred image inputs. In contrast to previous work, our approach is able to handle different types of blur and demonstrates state-of-the-art performance in the presence of both motion blur and defocus blur. Moreover, we adjust the computation effort with the amount of blur in the input image. As a first stage, our method uses a feed-forward image deblurring model for which we propose a suitable training scheme that can improve both tracking and mapping modules. Frames that are successfully deblurred by the feed-forward network obtain refined poses and depth through local-global multi-view optimization and loop closure. Frames that fail the first stage deblurring are directly modeled through the global 3DGS representation and an additional blur network to model multiple blurred sub-frames and simulate the blur formation process in 3D space, thereby learning sharp details and refined sub-frame poses. Experiments on several real-world datasets demonstrate consistent improvements in both pose estimation and sharp reconstruction results of geometry and texture.
