摘要:

精确的定位对于机器人技术和增强现实应用(例如自主导航)至关重要。结合先验地图的基于视觉的方法旨在将LiDAR级别的精度与相机的成本效率相结合,以实现鲁棒的位姿估计。然而,现有方法在将离散点云地图与密集图像像素关联时,通常依赖于不可靠的插值过程,这不可避免地会引入深度误差并降低位姿估计精度。我们提出了一种利用连续3D高斯地图的单目视觉里程计框架,该框架直接为所有提取的高梯度点分配几何一致的深度值,而无需进行插值。在两个公开数据集上的评估表明,与现有方法相比,该方法具有更高的跟踪精度。我们已发布本工作的源代码以促进社区的发展。

英文摘要:

Accurate localization is essential for robotics and augmented reality applications such as autonomous navigation. Vision-based methods combining prior maps aim to integrate LiDAR-level accuracy with camera cost efficiency for robust pose estimation. Existing approaches, however, often depend on unreliable interpolation procedures when associating discrete point cloud maps with dense image pixels, which inevitably introduces depth errors and degrades pose estimation accuracy. We propose a monocular visual odometry framework utilizing a continuous 3D Gaussian map, which directly assigns geometrically consistent depth values to all extracted high-gradient points without interpolation. Evaluations on two public datasets demonstrate superior tracking accuracy compared to existing methods. We have released the source code of this work for the development of the community.
