摘要:

我们介绍了一种方法,用于恢复多个已知对象的6D姿态在一个场景中捕获的一组输入图像与未知的相机视点。首先,我们提出了一个单视图单对象的6D姿态估计方法,我们使用它来生成6D对象的姿态假设。其次,我们开发了一种强大的方法,用于在不同的输入图像中匹配各个6D对象的姿态假设,以便联合估计相机的视点和6D构成的所有对象在一个单一的一致的场景。我们的方法明确地处理对象的对称性,不需要深度测量,是强大的丢失或不正确的对象假设,并自动恢复场景中的对象的数量。第三,我们开发了一种全局场景细化的方法,给出了多个对象的假设和它们在视图之间的对应关系。这是通过解决对象级光束法平差问题来实现的,该问题细化相机和对象的姿态以最小化所有视图中的重投影误差。我们证明了所提出的方法,被称为CosyPose,优于当前最先进的单视图和多视图6D对象姿态估计的结果,在两个具有挑战性的基准:YCB视频和T-LESS数据集。代码和预训练模型可在项目网页https://www.di.ens.fr/willow/research/cosypose/上获得。

英文摘要:

We introduce an approach for recovering the 6D pose of multiple known objects in a scene captured by a set of input images with unknown camera viewpoints. First, we present a single-view single-object 6D pose estimation method, which we use to generate 6D object pose hypotheses. Second, we develop a robust method for matching individual 6D object pose hypotheses across different input images in order to jointly estimate camera viewpoints and 6D poses of all objects in a single consistent scene. Our approach explicitly handles object symmetries, does not require depth measurements, is robust to missing or incorrect object hypotheses, and automatically recovers the number of objects in the scene. Third, we develop a method for global scene refinement given multiple object hypotheses and their correspondences across views. This is achieved by solving an object-level bundle adjustment problem that refines the poses of cameras and objects to minimize the reprojection error in all views. We demonstrate that the proposed method, dubbed CosyPose, outperforms current state-of-the-art results for single-view and multi-view 6D object pose estimation by a large margin on two challenging benchmarks: the YCB-Video and T-LESS datasets. Code and pre-trained models are available on the project webpage https://www.di.ens.fr/willow/research/cosypose/.
