Hi Landel Tech 1 I would like to have a question: what is the difference between calibration by a file from your computer and calibration by live video. Will dimention of object be changing significantly ?
They are the same. You can take the calibration cell structure and save it as a file on the computer then import it into a different inspection. As long as the physical setup doesn't move the calibration will still be valid.
For the most part, yes. The intersections are what the camera uses to calibrate itself. If you can't use a grid there are other methods such as point calibration. I may have done a video on that.
@@landeltech1240 Thanks for the answer. I was hoping not to have to glue the grid to the piece but if is mandatory i will do it. And another question : if I have the camera at 45 degrees with respect to the piece, does something change for the calibration?

calibration by live video means when we use check board for calibration

I'm not calibrating with a computer. Just importing an already saved calibration into a new spreadsheet.
Does this answer your question?
Thanks for the video. Is mandatory print the grid ?

I glued the grid to a piece of cardboard.
Process doesn't change for a 45 degree tilt.
