We are happy to announce that our paper “SynPo-Net–Accurate and Fast CNN-Based 6DoF Object Pose Estimation Using Synthetic Training” has been accepted for publication at the MDPI Sensors journal, Special Issue Object Tracking and Motion Analysis. Sensors (ISSN 1424-8220; CODEN: SENSC9) is the leading international peer-reviewed open access journal on the science and technology of sensors.
Abstract: Estimation and
tracking of 6DoF poses of objects in images is a challenging problem of great
importance for robotic interaction and augmented reality. Recent approaches
applying deep neural networks for pose estimation have shown encouraging
results. However, most of them rely on training with real images of objects
with severe limitations concerning ground truth pose acquisition, full coverage
of possible poses, and training dataset scaling and generalization capability.
This paper presents a novel approach using a Convolutional Neural Network (CNN)
trained exclusively on single-channel Synthetic images of objects to regress
6DoF object Poses directly (SynPo-Net). The proposed SynPo-Net is a network
architecture specifically designed for pose regression and a proposed domain
adaptation scheme transforming real and synthetic images into an intermediate
domain that is better fit for establishing correspondences. The extensive
evaluation shows that our approach significantly outperforms the
state-of-the-art using synthetic training in terms of both accuracy and speed.
Our system can be used to estimate the 6DoF pose from a single frame, or be
integrated into a tracking system to provide the initial pose.
