markers weight and adjusting virtual markers position
Posted: Wed May 03, 2023 8:56 am
Hello everyone,
I am working on a biomechanical modeling project using OpenSim software to estimate lower limb joint angles. For this, I have placed markers on the lower limb based on plug-in-gait lower limb protocol. However, during my experiments, I placed markers on a stick that was 2-4 cm away from the skin instead of attaching them directly to the skin.
My question is: should I give weight zero to these markers during scaling, or should I manually adjust tibia and thigh virtual markers position to match the experimental markers on the tibia and thigh?
Given the fact that these markers were placed on a stick and not directly on the skin during the experiments, what would be the best approach? How much weight should I give to these markers during scaling and during IK analysis? And should I manually adjust their position during scaling?
I would really appreciate any suggestions or insights on this matter. Thank you in advance.
