Pose Estimation AI VisionPose Utilized for Musculoskeletal Analysis
We used the pose estimation AI “VisionPose” for musculoskeletal analysis in our software “AnyBody”.

Initial Business Requirements
AnyBody is a musculoskeletal modeling and biomechanics CAE software that estimates human muscle strength and muscle activity, and calculates the mechanical forces and joint torques required to achieve the movement based on motion data. The movement information (=motion data) needs to be provided by the user.
Recently, we have been receiving an increasing number of inquiries about motion data acquisition (motion capture) methods that do not use markers or sensors, rather than traditional optical or inertial motion capture systems. We have been looking for a technology to identify human motion from image-based information (images and videos) without attaching measurement markers or sensors to the subject, and without preparing multiple expensive cameras or expensive sensors.

Why We Choose VisionPose
We learned about VisionPose and its excellent estimation accuracy from several of our customers. We compared the results of the “AnyBody” analysis with both the feature point estimation data from “VisionPose” and the data from our optical motion capture system. We confirmed that, depending on the conditions, the analysis results were equivalent to those of the optical motion capture system. We have posted and introduced this on our website, as an example of applying marker-less pose estimation data.

The body feature point coordinates estimated by VisionPose are input into AnyBody for motion analysis.
Implementation Results and Future Outlook
We have realized that with VisionPose, posture can be reasonably estimated from images and videos alone, and due to its uncomplicated use, we believe that the needs for its application will increase in the future.
