Vicon Integration

This module bundles all the components which can be used to process a session of trials measured by a marker based Vicon system. The „old“ Vicon Workstation is supported as well as the current Nexus system.

Vicon Workstation

Read/write routines for file formats specif for the Vicon Workstation are supported (see the table) and the c3d format with the Vicon specific undocumented extentions.

Extention Description Mime type
.enf Trial meta data. text/vicon-enf
.mp Model parameters (session based)
.mkr Markerset text/vicon-mkr
.sp Parameters (not used yet) text/vicon-sp
.tvd Vicon Video Data (recognized but not supported) application/vicon-tvd
.vad Vicon Analog Data application/vicon-vad
.c3d C3d file format with Vicon specific undocumented extentions. application/vicon-c3d

Processing Vicon Session details

Each Vicon trial is represented by a set of different files with the same file name but different suffixes. The marker timeseries are read from the .c3d-files and additional meta data is read from ent correspoding .enf-files. The enf-Files can include different groups of properties. In the current implementation of the ViconTrialSet class only the properties from the „TRIAL_INFO“ groups are read and saved in the .d3d-files in the property group „ALL“.

Additional properties are added to the meta data. Have a look at following table.

Property name Description
SESSION This attributes should include the name of a session. The directory name which includes the trial is used as session name if it not starts with „Group“, else the name of the directory which includes this directory is used instead. (This property is added by the ViconTrialSet class)
