Comparative Evaluation of 3D Reconstruction Methods for Object Pose Estimation
Abstract
Current generalizable object pose estimators i.e. approaches that do not need to be trained per object rely on accurate 3D models. Predominantly CAD models are used which can be hard to obtain in practice. At the same time it is often possible to acquire images of an object. Naturally this leads to the question of whether 3D models reconstructed from images are sufficient to facilitate accurate object pose estimation. We aim to answer this question by proposing a novel benchmark for measuring the impact of 3D reconstruction quality on pose estimation accuracy. Our benchmark provides calibrated images suitable for reconstruction and registered with the test images of the YCB-V dataset for pose evaluation under the BOP benchmark format. Detailed experiments with multiple state-of-the-art 3D reconstruction and object pose estimation approaches show that the geometry produced by modern reconstruction methods is often sufficient for accurate pose estimation. Our experiments lead to interesting observations: (1) Standard metrics for measuring 3D reconstruction quality are not necessarily indicative of pose estimation accuracy which shows the need for dedicated benchmarks such as ours. (2) Classical non-learning-based approaches can perform on par with modern learning-based reconstruction techniques and can even offer a better reconstruction time-pose accuracy tradeoff. (3) There is still a sizable gap between performance with reconstructed and with CAD models. To foster research on closing this gap the benchmark is made available at https://github.com/VarunBurde/reconstruction_pose_benchmark.
