摘要:

许多手持式或混合现实设备与单个传感器一起用于3D重建,尽管它们通常包括多个传感器。多传感器深度融合能够显著提高3D重建方法的鲁棒性和准确性,但现有技术不足以处理以不同值范围以及噪声和离群值统计操作的传感器。为此,我们引入了SenFuNet,这是一种深度融合方法,可以学习特定于传感器的噪声和离群值统计数据,并以在线方式组合来自不同传感器的深度帧数据流。我们的方法融合多传感器的深度流,而不管时间同步和校准和推广以及很少的训练数据。我们在现实世界的CoRBS和Scene3D数据集以及CNAS数据集上使用各种传感器组合进行实验。实验表明,我们的融合策略优于传统的和最近的在线深度融合方法。此外,多个传感器的组合比使用单个传感器产生更鲁棒的离群值处理和更精确的表面重建。源代码和数据可在https://github.com/tfy14esa/SenFuNet上获得。

英文摘要:

Many hand-held or mixed reality devices are used with a single sensor for 3D reconstruction, although they often comprise multiple sensors. Multi-sensor depth fusion is able to substantially improve the robustness and accuracy of 3D reconstruction methods, but existing techniques are not robust enough to handle sensors which operate with diverse value ranges as well as noise and outlier statistics. To this end, we introduce SenFuNet, a depth fusion approach that learns sensor-specific noise and outlier statistics and combines the data streams of depth frames from different sensors in an online fashion. Our method fuses multi-sensor depth streams regardless of time synchronization and calibration and generalizes well with little training data. We conduct experiments with various sensor combinations on the real-world CoRBS and Scene3D datasets, as well as the Replica dataset. Experiments demonstrate that our fusion strategy outperforms traditional and recent online depth fusion approaches. In addition, the combination of multiple sensors yields more robust outlier handling and more precise surface reconstruction than the use of a single sensor.
