Thanks for help. Now i know more and can move on. Спасибо большое ( on Russian language) Added new edits above

Hello everyone ! I wanted to calibrate my camera ( Bus 001 Device 002: ID 058f:3881 Alcor Micro Corp.) screen I did everything that was written in this article

and tried with this video

But nothing happened

My algorithm of actions 1) git clone image_pipeline in folder src in catkin_ws 2) entered the folder catkin_ws then catkin_make 3) roscore in another terminal 4) source .devel/setup.bash 5) rosdep install camera_calibration

until this step everything is fine

6) then i checked what topics are running rostopic list (and now i have first trouble) i saw only
/rosout /rosout_agg (screen) although must see /camera/camera_info /camera/image_raw

then I leave it without attention and went to the next step. In a little window picture freezes and I saw in terminal bunch of errors with title: error data jpeg or something like that Camera calibration window doesn't see images from camera

screen 1 screen 2

New algorithm:

1)roscore

2)

The traceback for the exception was written to the log file

On this step I've already have a problem

3) rosrun nodes ( Hope I done it right)

I've done camera calibration. I used a usb_cam package The whole problem was in terrible usb camera. I bought a new camera Logitech c615 and it worked perfectly

I edited cpp file where for source node was chosen video0 instead of video 1 in .launch file I did the same

Algorithm (If needed): 1) catkin_make and catkin_make install in a catkin_ws folder 2)roscore 3)source setup.bash in catkin_ws/devel in a folder 4) rosrun usb_cam usb_cam_node 5)rosrun camera_calibration cameracalibrator.py –size 8×6 –square 0.028 image:=/usb_cam/image_raw camera:=/usb_cam that's it Thanks to peteblackerthe3rd for help.

Sorry, It’s my first practice with ROS, so I can be very slow in some situations. I launched usb_cam_test and it was fin

I did it again with publishing the nodes (I think) , but i can't launch image_proc. Added new edits above. What I'm sup
