visp_tracker \object_position_hint

[dvedova]

Hi, when I run the visp_tracker, I can get it to track a model that I defined. Sometimes the tracker will fail, and when it does fail, I'd like to try and automatically reinitialize. According to the documentation, if I publish an estimation of the location of the model I wish to track to the topic named \object_position_hint, the visp_tracker will try to use this estimate to re-initialize the tracker.

In order to get the tracker to re-initialize, is there anything else I need to do? (Other than publishing my estimate to \object_position_hint?)

Is there some additional parameter or option I must set to true in order to get the tracker to use the information in \object_position_hint?
