The OptiTrack System will detect and track pre-defined objects equipped with IR markers. This system only works on Windows so a Yarp Module was implemented to send the object's data to a Yarp Port, that can be accessed from every PC containing Yarp. To run this Software you need to download this ZIP file and extract it to a ZIP_FOLDER.
SOFTWARE - http://users.isr.ist.utl.pt/~nmoutinho/OptiTrack/OptiTrack.zip
Then you need to install Tracking Tools so Windows can recognize the OptiTrack and install the correct drivers:
- 32 bits: http://users.isr.ist.utl.pt/~nmoutinho/OptiTrack/TrackingTools.2.5.1.Final_x32.exe - 64 bits: http://users.isr.ist.utl.pt/~nmoutinho/OptiTrack/TrackingTools.2.5.1.Final_x64.exe
These versions were tested and they work.
After this you only need to run the start.bat file located on the ZIP_FOLDER and all the object's data will be sent to a Yarp Port named "/optitrack/trackable_objects". The data sent to this port is a Yarp Bottle containing:
DATA: [Time Stamp , Number of Trackable Objects , Trackable ID_1 , Position_1 , Quaternion_1 , Euler_1 , ... , Trackable ID_n , Position_n , Quaternion_n , Euler_n], considering we have n objects.
NOTE: Only visible object's data will be send to the Yarp Port.
Create New Trackable Object
The file "project.ttp" has already defined one trackable object. To add a new object to the project:
- Run the Tracking Tools program - Click on Open Existing Project and choose the project file (located on ZIP_FOLDER/src/Data/project.ttp) - Go to View -> Trackable Properties to activate the Trackables objects properties
On the Perspective View window you will see white points corresponding to the markers on the scene.
- Press the Ctrl key and with the left button of the mouse click on each white point you want to be part of your new trackable object - Click on Create From Selection on the Trackables properties window. - Click on Save
DONE! You have created a new object and from now on you will be able to track it everytime it appears on the scene.
