Multimodal Motion Capture Dataset (TNT15)

Timo v. Marcard, Gerard Pons-Moll, and Bodo Rosenhahn

Video-based human motion capture has been a very active research area for decades now. The articulated structure of the human body, occlusions, partial observations and image ambiguities makes it very hard to accurately track the high number of degrees of freedom of the human pose. Recent approaches have shown, that adding sparse orientation cues from Inertial Measurement Units (IMUs) helps to disambiguate and improves full-body human motion capture. As a complementary data source, inertial sensors allow for accurate estimation of limb orientations even under fast motions.
In the research landscape of marker-less motion capture, publicly available benchmarks for video-based trackers (e.g. HumanEva, Human3.6M) generally lack inertial data. One exception is the MPI08 dataset, which provides inertial data of 5 IMUs along with video data.
This new dataset, called TNT15, consists of synchronized data streams from 8 RGB-cameras and 10 IMUs. In contrast to MPI08 it has been recorded in a normal office room environment and the high number of 10 IMUs can be used for new tracking approaches or improved evaluation purposes.

Multisensor-Fusion for 3D Full-Body Human Motion Capture (MPI08)

Gerard Pons-Moll, Andreas Baak, Thomas Helten, Meinard Müller, Hans-Peter Seidel, and Bodo Rosenhahn

In this work, we present an approach to fuse video with orientation data obtained from extended inertial sensors to improve and stabilize full-body human motion capture. Even though video data is a strong cue for motion analysis, tracking artifacts occur frequently due to ambiguities in the images, rapid motions, occlusions or noise. As a complementary data source, inertial sensors allow for drift- free estimation of limb orientations even under fast motions. However, accurate position information cannot be obtained in continuous operation. Therefore, we propose a hybrid tracker that combines video with a small number of inertial units to compensate for the drawbacks of each sensor type: on the one hand, we obtain drift-free and accurate position information from video data and, on the other hand, we obtain accurate limb orientations and good performance under fast motions from inertial sensors. In several experiments we demonstrate the increased performance and stability of our human motion tracker.

Pose Tracking and Motion Capture Test Sequences (TPAMI09 benchmark)

Thomas Brox, Bodo Rosenhahn, Juergen Gall, and Daniel Cremers
N. Hasler, B. Rosenhahn, T. Thormählen, M. Wand, J. Gall, and H.-P. Seidel

Due to several requests and interest of other research groups on our image sequences we use for model driven tracking, we decided to make them freely available for your own tests and experiments. The sequences (usually) contain the images, projection matrix(es), 3D model and pose init (as 4x4 matrix and a list of joint angles (optional)).
