Hi,
I'm trying to calibrate realsense in a similar fashion as i did for Kinect in ROS using a checkerboard.
For RGB----->rosrun camera_calibration cameracalibrator.py image:=/camera/color/image_raw camera:=/camera/color --size 8x6 --square 0.0245
For Depth-->rosrun camera_calibration cameracalibrator.py image:=/camera/color/image_rect_raw camera:=/camera/depth --size 8x6 --square 0.0245
But everytime i get the error service not found.
But when i did for kinect it saved .yaml file automatically in .ros folder. I already did the dynamic calibration as mentioned on Intel website. But that calibration file i guess i cannot use .yaml file in ros. So, i was trying to get the same .yaml file for d415 in ROS. Please help.

On a question on the RealSense GitHub site about getting a .yaml for D415, an Intel support member suggested getting the required information with an SDK program called rs-enumerate-devices, using the '-c' command to retrieve calibration information.

Thanks for your reply. I did " rs-enumerate-devices-c" and it spits a bunch of data but how i'm supposed to use it as a .yaml file which should be stored in .ros folder so that whenever i do roslaunch it should open with those calibrated parameters.

I do not know anything about the workings of yaml files unfortunately. You can though apparently dump parameters to a yaml file in ROS using the command 'rosparam dump'.
http://wiki.ros.org/rosparam# rosparam_dump http://wiki.ros.org/rosparam# rosparam_dump
If you want to know more about yaml file creation, a good place to ask may be the RealSense GitHub, where the RealSense engineers and developers are. You can post there by going to the link below and clicking the 'New Issue' button.

Just 1 more thing i already did dynamic calibration. I checked with the depth tool as well. It looks quite ok till 3-4m. So do i need to do custom calibration as well?

'Custom calibration' describes the calibration process, and 'dynamic calibration' refers to the name of the calibration software (the Dynamic Calibration API). So if you have used the Dynamic Calibration software then you have already done a custom calibration.
It is normal for the depth accuracy to start drifting noticeably after 3 to 4 m. It is called RMS Error, where depth noise increases over distance.

So when i'm launching roslaunch realsense2_camera rs_camera.launch
Even though if i type rqt_image_view, i am able to see rgb and depth images but anybody knows about these error. I guess its either because of kernel issue or sdk.

If you want to use RGBD mode, please try using this launch instruction instead:
roslaunch realsense2_camera rs_rgbd.launch

Still getting exactly the same error. Is it my SDK version??

Fourcc code errors are difficult to resolve. It can be hard to solve because past cases of them on this forum typically end up without a clear resolution. I see you have posted the case on the GitHub too, and that may be the best place for you to get a resolution.
There has been a previous case on this forum of fourcc code RW16. That case was unresolved, but the details may be helpful to you.
