ROS2 and Fusion API

Is it currently possible to create a ROS2 node that does not directly attach to a camera but subscribes to camera data from other nodes and uses the fusion API to perform multi camera body tracking on that data?

If so, what topics would it make sense to subscribe to?

Hi @ml22
Welcome to the Stereolabs community.

Our roadmap currently does not include porting the Fusion module to the ROS Wrapper 2, only partially supporting GNSS in a single-camera setup.

You could create your ROS 2 wrapper around the sl::Fusion class that retrieves the information from ā€œNā€ running ROS 2 Nodes.
You must also modify the code of the sl::ZedCamera component to enable the publishing of the camera information to the Fusion module:
