Scaling opensim

WebThe scaling procedure was performed by the scaling tool of the OpenSim software. The inverse kinematics (IK) was used to quantify the hip, knee, and ankle kinematics [ 8 , 9 , 10 ]. The IK estimates a weighted least-squares equation to minimize the length between model marker data ( x i ) and surface reflective marker data ( x ¯ i ) in each ...

Scaling is one of the most important steps in solving inverse kinematics and inverse dynamics problems because these solutions are sensitive to the accuracy of the scaling step. In OpenSim, the scaling step adjusts both the mass properties (mass and inertia tensor), as well as the dimensions of the body segments.

The scaling step scales the mass properties (mass and inertia tensor) of the model, as well as the dimensions of the body segments. Many of the elements attached to the body segments, such as muscle actuators and wrapping objects are also scaled. The scaling algorithm uses a multi-stage process and each stage … See more Scaling is performed based on a combination of measured distances between x-y-z marker locations and manually-specified scale factors. The marker locations … See more After scaling the model, the next step is to move the model's markers to match experimental marker locations in a static pose.
