How can I receive extrinsic_calibration service?

[enddl3224]

Hi, I'm trying to use camera-lidar calibration tool using tag_based_pnp_calibrator.launch.xml. and I want to check the values(initial_reprojection_error, current_reprojection_error, filtered_reprojection_error).

If I receive extrinsic_calibration service, then request_received_ = true; I think I can also get the above values as well.

How can I receive extrinsic_calibration service?

I'm attaching some pictures.

• Code

• Image view

• TF tree

• node, topic info

Thank you.

@enddl3224 Although you provided a lot of data I don't fully understand. Are you using the calibrator manager? If not, you can always send the service manually

Thank you for comment! I'm using the calibrator manager(sensor_calibration_manager). But could you tell me how can I send the service manually? I guess I didn't send the service.

Please check if the service name from both the server and the client coincide. When creating launchers, it is the most common mistake, and that is why newer versions should allow to use the tools without writing launchers (the so called default project). To send services manually just type ros2 service call service_name and then use autocomplete to deduce the type and contents. Sadly, that is out of the scope of the support we can do as it falls outside the intended use of these tools and correspond to the integration work of users

Thank you so much! I'll try it.
