摘要:

我们提出了一种新的方法来估计重叠对的三维视图在室内场景的上下文中的运动矩阵。我们使用曼哈顿世界假设,以平面的形式引入轻量级的几何约束到问题中,这降低了复杂性,考虑到场景的结构。特别是,我们定义了一个随机的框架来分类平面垂直或水平,平行或非平行。我们利用这种分类来匹配对平面重叠的观点与观点不可知的结构指标。我们建议分裂的运动计算使用的分类和估计分别旋转和平移的传感器,使用二次最小。我们验证了我们的方法在一个玩具的例子,并提出了定量实验上的一个公共RGB-D数据集,与最近的国家的最先进的方法进行比较。我们的评估表明,平面约束只增加了低的计算开销,同时提高精度后,应用于事先粗略估计的结果。最后,我们对目前的结果的扩展和改进的提示。

英文摘要:

We present a novel method to estimate the motion matrix between overlapping pairs of 3D views in the context of indoor scenes. We use the Manhattan world assumption to introduce lightweight geometric constraints under the form of planes into the problem, which reduces complexity by taking into account the structure of the scene. In particular, we define a stochastic framework to categorize planes as vertical or horizontal and parallel or non-parallel. We leverage this classification to match pairs of planes in overlapping views with point-of-view agnostic structural metrics. We propose to split the motion computation using the classification and estimate separately the rotation and translation of the sensor, using a quadric minimizer. We validate our approach on a toy example and present quantitative experiments on a public RGB-D dataset, comparing against recent state-of-the-art methods. Our evaluation shows that planar constraints only add low computational overhead while improving results in precision when applied after a prior coarse estimate. We conclude by giving hints towards extensions and improvements of current results.
