Then run using "rosrun optitrackros forward_pos_to_drone.py"
The script launches a topic called "CameraStream" and publishes the following data in a message type defined in "Camera.msg"
float32 label float32[3] pos float32[4] quart float32 timestamp
The label corresponds to the label value defined in the dictionary "bodynames" on line 37 of "forward_pos_to_drone.py".
The keys in the dictionary must correspond to the names of the rigid bodies that are to be tracked as defined on the Motive software for Optitrack.
