CAPTRA: CAtegory-level Pose Tracking for Rigid and Articulated Objects from Point Clouds

Abstract: ing the small pose regime in the pose-canonicalized point clouds, our method integrates the best of both worlds by combining dense coordinate prediction and direct rotation regression, thus yielding an end-to-end differentiable pipeline optimized for 9DoF pose accuracy (without using non-differentiable RANSAC). Our extensive experiments demonstrate that our method achieves new state-of-the-art performance on category-level rigid object pose (NOCS-REAL275 [29]) and articulated object pose benchmarks (SAPIEN [34… Show more

“…The benefit of exploiting temporal consistency is obvious by comparing the single frame and tracking performance in Table I. We compare our category-level 6D object pose tracking system with ICP [46], 6-PACK [14], CAPTRA [15], and BundleTrack [16]. Overall, our system achieves better performance compared to 6-PACK and ICP in terms of overall IoU25, mean rotation error, and mean translation error.…”

“…Some recent progress has been made to address the problem of category-level 6D pose estimation [11]- [16]. Besides the mentioned work on category-level pose estimation for single frames such as NOCS [11], CASS [12], FS-Net [13] and the category-level tracking work 6-PACK [14], recently, Weng et al [15] propose a unified framework that can handle 9DoF category-level pose tracking for rigid object instances. More recently, Wen et al propose BundleTrack [16] which uses deep neural networks to extract and match keypoints, then pose graph optimization is used for pose tracking.…”

“…Both directions require the robot to learn about each object from scratch, no matter how similar the object is to those it has previously experienced. To address this issue, recent works have proposed to predict canonicalized object coordinates [32] for category-level articulated object pose estimation [3], [10]. However, such representation is designed specifically for articulated pose estimation and can't perform other tasks such as shape reconstruction or view synthesis.…”

“…• We show that the proposed representation can perform category-level articulated pose estimation through analysis-by-synthesis with only RGB inputs. To the best of our knowledge, existing works for this task all require depth inputs [3], [10], [11], [12].…”

“…Modeling articulated objects has wide applications in multiple fields including virtual and augmented reality, ob-ject functional understanding, and robotic manipulation. To understand articulated objects, recent works propose to train deep networks for estimating per-part poses and the joint angle parameters of an object instance in a known category [41,83]. However, if we want to interact with the articulated object (e.g., open a laptop), estimating its static state is not sufficient.…”
