MonoEye: A human motion capture system using a single wearable camera – Science Daily
Researchers at Tokyo Institute of Technology (Tokyo Tech) and Carnegie Mellon University have together developed a new human motion capture system that consists of a single ultra-wide fisheye camera mounted on the user’s chest. The simplicity of their system could be conducive to a wide range of applications in the sports, medical and entertainment fields.
Computer vision-based technologies are advancing rapidly owing to recent developments in integrating deep learning. In particular, human motion capture is a highly active research area driving advances for example in robotics, computer generated animation and sports science.
Conventional motion capture systems in specially equipped studios typically rely on having several synchronized cameras attached to the ceiling and walls that capture movements by a person wearing a body suit fitted with numerous sensors. Such systems are often very expensive and limited in terms of the space and environment in which the wearer can move.
Now, a team of researchers led by Hideki Koike at Tokyo Tech present a new motion capture system that consists of a single ultra-wide fisheye camera mounted on the user’s chest. Their design not only overcomes the space constraints of existing systems but is also cost-effective.
Named MonoEye, the system can capture the user’s body motion as well as the user’s perspective, or ‘viewport’. “Our ultra-wide fisheye lens has a 280-degree field-of-view and it can capture the user’s limbs, face, and the surrounding environment,” the researchers say.
To achieve robust multimodal motion capture, the system has been designed with three deep neural
