METHOD AND SYSTEM OF CONSTRAINT-BASED OPTIMIZATION OF DIGITAL HUMAN UPPER LIMB MODELS

摘要

PROBLEM TO BE SOLVED: To provide an upper limb model of a virtual manikin for predicting a posture having high robustness.SOLUTION: An upper limb model of a virtual manikin includes a data conversion engine configured to produce converted data based on one or more data sets. Each data set represents dependencies between elements of the kinematic model. The upper limb model further includes a kinematic chain model configured to generate one or more constraints based on the converted data. The upper limb model also includes a posturing engine configured to determine, based on the one or more constraints, a trajectory from a first position to a second position. The kinematic model may further include a rendering engine configured to render a posture corresponding to the second posture. The elements of the kinematic model may include one or more of a clavicle, a scapula, a humerus, a forearm and a hand.SELECTED DRAWING: Figure 5
