How to make camera calibration #124

System Description Camera Name and Model: BFS-U3-16S2M-CS Operating System: Ubuntu 18.04 Bionic Spinnaker Version: 2.2.0.48 ROS Version: Melodic

Computer details Processor: Xavier AGX RAM: 32G

Do the cameras work with SpinView? Yes.

problem describe:

I use ROS camera_calibration [http://wiki.ros.org/camera_calibration] to find distortion, intrinsic and projection coefficient, then put into the test_params.yaml but output image didn't make any changes. Does anyone know how to make the camera calibration correctly ?

@Keddie-yang the camera driver does not correct for the camera distortion or intrinsic parameters. It just publishes that information as CameraInfo messages. The node which uses the images can read the CameraInfo messages and correct for distortion etc.

OK, I get it. Thank you.
