How can I get acceleration ground truth from VICON?

edit

Hi.

My advice would be to capture the data by running the cameras as quickly as possible without sacrificing strobe illumination - This depends on the type of camera.

Ideally, any filter algo needs to incorporate terms for the motion model of the object being tracked. It latency is not so important, smoothing functionality is available within Vicon Tracker that implements a simple moving average smoothing algorithm, you can set the window of this filter to as many as is comfortable for your application.
