libmotioncapture

Interface Abstraction for Motion Capture System APIs such as VICON, OptiTrack, Qualisys, Nokov, or VRPN.

This can be used as C++ library or Python package. For Python, use

pip install motioncapture

For C++, follow the instructions below.

This is a fork of https://github.com/USC-ACTLab/libmotioncapture/ with the following changes:

• Python bindings
• Factory method
• Refactored API
• Support for VRPN by default

Compile options

By default, libmotioncapture supports the following hardware:

• VICON - SDK git submodule
• Qualisys - SDK git submodule
• OptiTrack - binary parsing over network (no dependency)
• VRPN - SDK git submodule
• NOKOV - manually obtain SDK and copy to deps/nokov_sdk/ and copy the .so file to the /lib or /usr/lib.

CMake flags can be used to disable individual systems in CMakeLists.txt.
