• calculate direction of view from ArucoMarkers (or to be more specific: orientation of ArucoMarker. (Under the assumtion, that it is alligned with the head, it becomes the head orientation))
• add checkbox "export Marker Orientation" to gui
• export in txt

added enhancement feature medium labels

"add checkbox "export Marker Orientation" to gui" necessary, because following export option is existing?

"autocorrect head direction" could try to chatch the error that someones marker is not alligned with the orientation/direction of the head

be careful to name is viewing direction; it is only the head direction; the viewing direction is the direction the person is looking at

added recognition label

added To Do label

After taking a first quick glance at this, following obstacles occur:

• for computation of the direction the camera matrix is needed, hence the CalibFilter needs to be passed down to the recognition part
• currently the view direction is computed via: colPos - pos is could lead to problems with the combination of code and multicolor markers. As in this case pos -> Code and colPos -> color marker
