Latest Patents

Yamane’s listed patents address motion capture and the mechanics of human-body models.

“Motion capture system and method for three-dimensional reconfiguring of characteristic point in motion capture system” describes an optical system that uses multiple cameras to capture a mesh marker on a subject. It detects the marker’s nodes and edges in camera images, then combines information from different views to reconstruct the nodes’ three-dimensional positions. The approach supports dense spatial measurement by increasing the number of measurement points.

“Body dynamics calculation method, body dynamics model and model data thereof, and body-model generation method” concerns fast forward and inverse mechanics calculations for human-body models containing skeletal geometry and muscle, cord, or band data. The method maps a new skeletal model to a predefined normal-body model to generate a corresponding body model. It also calculates how forces applied through muscles or virtual links affect the model’s motion, including its joint forces, accelerations, velocities, and positions.
