Can’t set PTP for ace2 camera

[leiwanrobotics]

Describe what you want to implement and what the issue & the steps to reproduce it are:

I want to sync my ace2 camera with gps time resource though PTP

Hardware setup description

Ubuntu22.04
ROS2 humble

Runtime information

When I set the ptp through ros service call, I can enable the ptp successfully. Then I Check Pott status through ros service as well, then it shows always waiting for service become available, it seems the camera didn’t get ptp. I also compare the timestamp of image with Unix timestamp, it’s 2 seconds different. But I can set PTP successfully though pylonviewer, it shows offset is around 100ns.

Is your camera operational with the Basler pylon Viewer on your platform?

Yes

Hello @leiwanrobotics
Just to be sure, so you are trying to synchronize 2 cameras together that's it? Can you describe a bit more your application ?
Can you please post the different ROS commands you are executing ?

Hi @FrancoisPicardDTI
Thanks for response. i am trying to sync camera with other sensors, like LiDAR. it's for autonomous vehicle. we have RTK to provide the time resource.

I execute the commands like:
ros2 service call /my_camera/pylon_ros2_camera_node/enable_ptp std_srvs/srv/SetBool "{data: true}"
ros2 service call /my_camera/pylon_ros2_camera_node/get_ptp_status std_srvs/srv/Trigger

Do you solve this problem ? @leiwanrobotics

I also use this command.

• ros2 service call /my_camera/pylon_ros2_camera_node/enable_ptp std_srvs/srv/SetBool "{data: true}"
• ros2 service call /my_camera/pylon_ros2_camera_node/get_ptp_status ""

waiting for service to become available...
requester: making request: pylon_ros2_camera_interfaces.srv.GetPtpStatus_Request()

response:
pylon_ros2_camera_interfaces.srv.GetPtpStatus_Response(ptp_status='', ptp_servo_status='', offset_from_master=0, success=False, message='The connected camera does not support this feature')
