📝 摘要(中文)
本研究提出了一种基于图像边缘特征的视觉里程计(VO)系统。边缘作为一种空间表达线索,广泛存在于各种环境中,提供丰富的纹理和结构信息。然而,现有的基于边缘的VO方法未能充分利用这一潜力。为此,我们引入了一种新颖的特征表示方法——有序边缘,将离散的边缘像素转化为顺序聚类,从而更有效地保留和利用底层的纹理和结构信息。此外,有序边缘能够在多帧间进行边缘级关联,建立共视图图。我们还提出了基于有序边缘特征的跟踪和联合优化方法,以实现精确高效的位姿估计。通过广泛的实验验证,该系统在室内环境中表现出色,超越或与最先进的方法相当。
🔬 方法详解
问题定义:本论文旨在解决传统边缘特征视觉里程计在信息利用上的不足,现有方法未能充分挖掘边缘特征的潜力,导致定位精度和鲁棒性不足。
核心思路:论文提出的有序边缘特征通过将离散的边缘像素转化为顺序聚类,增强了对纹理和结构信息的保留与利用,同时支持多帧间的边缘级关联,建立共视图图。
技术框架:整体架构包括边缘特征提取、边缘跟踪和联合优化三个主要模块。边缘特征提取阶段利用有序边缘进行信息聚合,跟踪阶段采用边缘级残差进行帧间注册,优化阶段则通过边缘拟合和有序边缘的束调整方法进行位姿优化。
关键创新:最重要的技术创新在于有序边缘特征的引入及其在边缘级关联和优化中的应用,这与传统的像素级方法有本质区别,能够更好地保留结构完整性。
关键设计:在跟踪过程中,采用边缘级而非像素级的残差计算,提升了注册的鲁棒性和准确性;在联合优化中,引入了形状保持的边缘拟合方法和有序边缘的束调整方法,确保了结构的完整性。

📄 摘要(原文)
This work presents a visual odometry (VO) system that leverages image edge features. Edges are spatially expressive cues commonly present across diverse environments, offering rich textural and structural information. However, existing edge-based VO methods often fail to fully exploit this potential. To this end, we introduce a novel feature representation termed \textit{organized edges}, which transforms disjoint edge pixels into sequentialized clusters, enabling more effective retention and utilization of the underlying textural and structural information. Another nice property of this formulation is that organized edges can perform edge-level association across multiple frames, enabling the establishment of a co-visibility graph. To achieve precise and efficient pose estimation, we propose a range of particularly designed tracking and joint optimization methods based on the characteristics of organized edges. For tracking, we formulate edge-wise rather than pixel-wise residuals to achieve robust and accurate inter-frame registration. For joint optimization, we introduce a novel shape-preserving edge-fitting method and an organized edge-based Bundle Adjustment (BA) approach, which decomposes the traditional BA problem into fitting and registration to preserve the structural integrity. Based on these novel techniques, we develop a complete VO system that exclusively employs organized edge features, achieving efficient tracking and precise local mapping. Extensive experiments demonstrate its accuracy and robustness in indoor environments, outperforming or achieving comparable performance to state-of-the-art methods.
