摘要:

本文提出了一种鲁棒的RGB-D SLAM系统,利用室内场景中的结构信息,在CPU上实现精确的跟踪和高效的密集映射。先前的工作已经使用曼哈顿世界(MW)假设来估计低漂移相机姿态,从而限制了此类系统的应用。本文,相比之下,提出了一种新的方法,提供强大的跟踪MW和非MW环境。我们检查平面之间的正交关系以直接检测曼哈顿帧,将场景建模为曼哈顿帧的混合。对于MW场景,我们解耦的姿态估计,并提供了一种新的漂移的旋转估计的基础上曼哈顿帧的意见。对于MW场景中的平移估计和非MW场景中的全相机姿态估计,我们利用点,线和平面特征在具有挑战性的场景中进行鲁棒跟踪。此外,通过利用在每帧中检测到的平面特征,我们还提出了一种有效的基于曲面的密集映射策略,该策略将每个图像划分为平面和非平面区域。平面曲面直接从我们的地图中的稀疏平面初始化,而非平面曲面通过提取超像素来构建。我们在姿态估计,漂移和重建精度的公共基准上评估了我们的方法,与其他最先进的方法相比,实现了卓越的性能。我们将在未来开放我们的代码。

英文摘要:

In this paper, a robust RGB-D SLAM system is proposed to utilize the structural information in indoor scenes, allowing for accurate tracking and efficient dense mapping on a CPU. Prior works have used the Manhattan World (MW) assumption to estimate low-drift camera pose, in turn limiting the applications of such systems. This paper, in contrast, proposes a novel approach delivering robust tracking in MW and non-MW environments. We check orthogonal relations between planes to directly detect Manhattan Frames, modeling the scene as a Mixture of Manhattan Frames. For MW scenes, we decouple pose estimation and provide a novel drift-free rotation estimation based on Manhattan Frame observations. For translation estimation in MW scenes and full camera pose estimation in non-MW scenes, we make use of point, line and plane features for robust tracking in challenging scenes. %mapping Additionally, by exploiting plane features detected in each frame, we also propose an efficient surfel-based dense mapping strategy, which divides each image into planar and non-planar regions. Planar surfels are initialized directly from sparse planes in our map while non-planar surfels are built by extracting superpixels. We evaluate our method on public benchmarks for pose estimation, drift and reconstruction accuracy, achieving superior performance compared to other state-of-the-art methods. We will open-source our code in the future.
