2012-10-15 03:32:08 -0600 | commented answer | How to calculate the distance from the camera origin to any of the corners? (square chessboard calibration) Thank you for your answer! If not a chessboard what would you use? I would like to care about the angle because the robot can stand anywhere in the room. |

I am kind of new to OpenCV and I was trying out the tutorials in the OpenCV tutorial sections - by the way really good tutorials, thx for the authors. The reason I started to trying out the tutorials, so I can get a little familiar with OpenCV. I have a project going on with a humanoid robot where I want to use OpenCV and try out some cool things. I already calibrated the robots camera thx to the OpenCV tutorials. I read both the calibration tutorials to get as much info about it as I can. At the end of this one there is a question (the same question what my topic has). Is there an answer to it somewhere, or is there somebody who could answer it? I would really appreciate it, because than I could use the chessboard for calibrating, image detecting, and for distance measurements! I realize I can't do everything with a help of a chessboard, but for starter, and as a beginner it would help me a lot! Parameters I have:
