using opencap for model scaling in opensim

hello,
I wanted to ask if it is possible to use Opencap software to scale the model in opensim? can we have the *.trc out put from opencap?

kind regards,

Re: Manual scaling and computation of segment scaling factors

Deaar Jing,
yes, and the markers must be in a same frame.

Kind regards,

Re: manual scaling tool

Dear jing liu, I used the same method that you mentioned. I put all markers in the ground frame to be able to calculate distances as body segments length. I think the accuracy will be aright if markers be placed on the functional joints, and in the same way we measure the subject's body segments len...

Re: IMU placer and Inverse Kinematics tool

Dear Dr. Ayman, many thanks for your response, you mentioned that changing the position of IMUs is for visualization purposes, does it mean that if (after using IMU placer) I change the place of IMUs (in the sidebar menu, properties window of each IMUs) from Center of mass into the correct place of ...

IMU placer and Inverse Kinematics tool

Hi everyone, I am using the IMU placer and Inverse Kinematics tools to calculate joint angles. I would be grateful if anyone could help me with the following matter: After using the IMU placer, it is possible to change the orientation of some IMUs and then use the IMU inverse kinematics tool. I want...

Re: Manual scaling and computation of segment scaling factors

Dear Vincent,

I am useing manual scaling, too. For the model's segment lengths, I put markers on the model in a same parent frame and calculated the marker distances.

I hope you find it helpful.

Best regards

scaling, heading direction

Hi Everyone, I am using Xsens data for Inverse Kinematics of a full body model. I had a question, I would appreciate if you can assist me: When I apply the required rotations, and defining the heading direction, the model walking direction will not match the heading direction that I defined. For exa...
