OptiTrack plug-in - stream unlabeled marker
Dear all,
I have recently bought an Optitrack V120:Trio System and I am currently trying to stream tracking data from Optitracks Software Motive to Vizard. I am using the following code: Code:
import viz viz.go optitrack = viz.add('optitrack.dle') motive = optitrack.addMotive('127.0.0.1') print motive.getMarkerList() 1) The returned marker list does not contain the label names, but names like "__builtin__._OptiTrackMarker(1)" 2) Unlabeld markers are not contained in the returned marker list. However, it is not possible to label single marker in Motive in Live mode. However, I do need to stream the position of single markers. Any ideas? Kind regards, Rennschu |

Does the marker have an index? If so, you could try the motive.getMarker(val) command and use the index value.

Hi Jeff,
we use the following code to try to get coordinates of the marker positions: Code:
import viz viz.go() optitrack = viz.add('optitrack.dle') motive = optitrack.addMotive('127.0.0.1') print motive.getMarkerList() marker = motive.getMarker(0) print marker.getPosition() The code returns the following text: ************************************************** **************************** ** Loading optitrack.py ************************************************** **************************** optitrack.dle OptiTrack Extension ** OptiTrack: [Client] Initializing using ethernet address: 127.0.0.1 ** OptiTrack: [Client] Initializing command listener. ** OptiTrack: [Client] Initializing data listener. ** OptiTrack: [Client] Connected. (HostApp: HostVer: 0.0.0.0 HostIP: 127.0.0.1 () [__builtin__._OptiTrackMarker(1), __builtin__._OptiTrackMarker(2), __builtin__._OptiTrackMarker(3), __builtin__._OptiTrackMarker(4)] [0.0, 0.0, 0.0] ** Load Time: 0.24 seconds So, we have the two problems: 1) The position is always [0.0,0.0,0.0] 2) Markers not belonging to a rigid body do not appear in the MarkerList Could you help us with that? |

I'll follow up with a developer. Can you tell me which versions of Vizard 5, Motive software, and Windows you are running?
