PosePerfect: refining 3D human pose estimation using anthropometric constraints and synthetic localization errors
摘要
Existing methods for 3D human pose estimation often suffer from localization errors primarily caused by inadequate modeling of bone length dependencies, self-occlusions, depth ambiguities, and pose diversity. To address this issue, we propose a novel refinement method that leverages anthropometric constraints and synthetic localization errors. Our approach comprises three modules: a synthetic error-guided pose refiner that fine-tunes coarse 3D poses, an anthropometric stature regressor that predicts the closest anthropometric stature, and an anthropometric pose refiner that further minimizes localization errors. Evaluated on the Human3.6M and MPI-INF-3DHP datasets, our method outperforms state-of-the-art 3D human pose estimation techniques, reducing localization errors by up to 2.5 mm and 1.3 mm, respectively. The proposed refine- ment method not only enhances the accuracy of 3D pose estimation but also demonstrates improved generalization capabilities.
