BVH driven box lift example#
Example of a MoCap model using data from an inertial measurement unit (IMU) based suit. The model uses a BVH file with data from an Xsens suit. The ground reaction forces are predicted using the GRF prediction algorithm.
Main file Example:
The model works using virtual markers placed on the BVH rig (i.e. the stick-figure model specified by the BVH file). The virtual markers are used to make the Musculoskeletal model moved similar to marker based MoCap models.
AnyBody automatically calculates the virtual markers positions, and the model is scaled directly from the size of the BVH stick figure. Hence the model contains no Parameter identification step to find the parameters. The remaining parts of the model are equivalent to other MoCap model based on C3D files.
This particular example shows how to model a box which connects to the hand segments. This is useful when investigation the effects of interaction with environment objects even when there is no kinematic data for that object.
