Description

I recorded zed2 topics using ros2 in a Rosbag file. I am aiming to replay this rosbag and utilize zed2 object detection on my rosbag data and visualize it in Rviz.

This is the zed/zed_node/obj_det/objects topic info Type: zed_interfaces/msg/ObjectsStamped

Publisher count: 0

Subscription count: 1

Node name: zed2_rviz2 Node namespace: /zed Topic type: zed_interfaces/msg/ObjectsStamped Endpoint type: SUBSCRIPTION GID: 01.0f.ad.42.7d.2d.bb.3b.01.00.00.00.00.00.40.04.00.00.00.00.00.00.00.00 QoS profile: Reliability: RELIABLE History (Depth): UNKNOWN Durability: VOLATILE Lifespan: Infinite Deadline: Infinite Liveliness: AUTOMATIC Liveliness lease duration: Infinite

I was adding object_detection enable parameter in zed_camera.launch.py file. I have attached my zed_camera.launch.py and terminal output for the same in the zip.
