摘要:

我们提出了一种技术,同时三维重建的静态区域和刚性移动的物体在场景中。RGB-D帧被表示为特征的集合,这些特征是点和平面。我们将特征分类为静态和动态区域,并为每个区域生成单独的地图,静态和对象地图。为了对每个帧中的特征进行鲁棒分类,我们将通过将不同组的特征注册到不同的地图而获得的多个基于RANSAC的注册结果进行融合,包括(1)将所有特征注册到静态地图,(2)将所有特征注册到每个对象地图,以及(3)将特征的子集(每个子集形成一个片段)注册到每个对象地图。这种多组配准方法旨在克服以下挑战:场景可以由静态区域主导,使得对象跟踪更加困难;与静态区域相比,移动对象在帧之间可能具有更大的姿态变化。我们展示了室内场景中各种形状的物体的定性结果。该技术使飞行中的对象模型生成用于机器人操作。

英文摘要:

We present a technique for simultaneous 3D reconstruction of static regions and rigidly moving objects in a scene. An RGB-D frame is represented as a collection of features, which are points and planes. We classify the features into static and dynamic regions and grow separate maps, static and object maps, for each of them. To robustly classify the features in each frame, we fuse multiple RANSAC-based registration results obtained by registering different groups of the features to different maps, including (1) all the features to the static map, (2) all the features to each object map, and (3) subsets of the features, each forming a segment, to each object map. This multi-group registration approach is designed to overcome the following challenges: scenes can be dominated by static regions, making object tracking more difficult; and moving object might have larger pose variation between frames compared to the static regions. We show qualitative results from indoor scenes with objects in various shapes. The technique enables on-the-fly object model generation to be used for robotic manipulation.
