object_position not published

[ank95]

Hi I am trying to estimate the pose of an object using visp_tracker. When i run the tutorial.launch and echo the object_position topic can see the estimated pose. But when i try to do the same using my own webcam, i don't see anything being published on the topic. tf only the transform between the camera and base_link.

I am running the vision_visp compiled from ROS package and i'm using Ubuntu 16.04 with ROS Kinetic.
