Issue with YOLOV11 Node Output

[besma14]

Hello,

I am using a Basler camera with ROS2, and its topic is configured as /cam0, /cam1 ... . I launch the YOLO node with the following command using the GPU: ros2 launch yolo_bringup yolov11.launch.py input_image_topic:="/cam1"
However, I do not receive any detection output on topics like /yolo/dbg_image or /yolo/detections. The camera is functioning correctly and publishing images on /cam0.

Could you please assist me in diagnosing and resolving this issue?

i have ROS2 Humble, ubuntu 22.04, i used the dockerfile

Thank you in advance for your support.

@besma14 can you check the QoS of the camera topics? Both, the publisher and subscriber must have the same QoS.

hi, I looked at the QoS as you mentioned as you can see in the screenshots and I still don't have an image

[besma14]

I changed the Qos to RELIABLE but I still don't have my image, please help me

@besma14 check if the /yolo/yolo_node is subscribed to you /cam1 topic.

@besma14 I also want to use Basler camera to realize YOLO real-time detection, can you help me solve some problems? How can I use the Basler camera to achieve detection in Rviz2
