• Title: BodySLAM: Joint Camera Localisation, Mapping, and Human Motion Tracking
• Authors: Dorian Henning, Tristan Laidlow, Stefan Leutenegger
• Abstract summary: Estimating human motion from video is an active research area due to its many potential applications. We present BodySLAM, a monocular SLAM system that jointly estimates the position, shape, and posture of human bodies. We also introduce a novel human motion model to constrain sequential body postures and observe the scale of the scene.

• Abstract: Estimating human motion from video is an active research area due to its many potential applications. Most state-of-the-art methods predict human shape and posture estimates for individual images and do not leverage the temporal information available in video. Many "in the wild" sequences of human motion are captured by a moving camera, which adds the complication of conflated camera and human motion to the estimation. We therefore present BodySLAM, a monocular SLAM system that jointly estimates the position, shape, and posture of human bodies, as well as the camera trajectory. We also introduce a novel human motion model to constrain sequential body postures and observe the scale of the scene. Through a series of experiments on video sequences of human motion captured by a moving monocular camera, we demonstrate that BodySLAM improves estimates of all human body parameters and camera poses when compared to estimating these separately.

  We present a method to estimate human motion in a global scene from moving cameras. This is a highly challenging task due to the coupling of human and camera motions in the video. We propose a joint optimization framework that disentangles human and camera motions using both foreground human motion priors and background scene features.

In contrast to prior work, our approach reconstructs human meshes in consistent global coordinates even with dynamic cameras.

  We introduce (HPS) Human POSEitioning System, a method to recover the full 3D pose of a human registered with a 3D scan of the surrounding environment. We show that our optimization-based integration exploits the benefits of the two, resulting in pose accuracy free of drift. HPS could be used for VR/AR applications where humans interact with the scene without requiring direct line of sight with an external camera.
