论文摘要
AR/VR应用程序和机器人需要知道场景何时更改。一个例子是将对象移动，添加或从场景中移动或删除时。我们提出了一个仅基于场景更改的3D对象发现方法。我们的方法不需要编码有关对象的任何假设，而是通过利用其连贯的动作来发现对象。最初将变化视为深度图的差异，并在对象进行严格的运动时被分割为对象。图切割优化将不断变化的标签传播到几何一致的区域。实验表明，我们的方法在针对竞争基线的3RSCAN数据集上实现了最先进的性能。我们方法的源代码可以在https://github.com/katadam/objectscanmove上找到。
AR/VR applications and robots need to know when the scene has changed. An example is when objects are moved, added, or removed from the scene. We propose a 3D object discovery method that is based only on scene changes. Our method does not need to encode any assumptions about what is an object, but rather discovers objects by exploiting their coherent move. Changes are initially detected as differences in the depth maps and segmented as objects if they undergo rigid motions. A graph cut optimization propagates the changing labels to geometrically consistent regions. Experiments show that our method achieves state-of-the-art performance on the 3RScan dataset against competitive baselines. The source code of our method can be found at https://github.com/katadam/ObjectsCanMove.
