ideal calibration boards (chessboard or circles)

Hi,

1-Does the opencv download not have an image of an ideal calibration board in it which one can print out and paste to a flat piece of metal?

2-The tutorial (which is really good btw) of which I am testing the code in the calibration section, lacks sample images with a calibration board in different poses? I do not yet have a camera connected and it would be handy to have some testing images at hand to run the calibration code on.

If either or both of above are in the opencv package it would be great to know where. I have not managed to locate them.

TIA.

  1. OpenCV source packages for Windows and Unix on SourceForge contains pattern.png and acircles_pattern.png images in doc folder. As I know, OpenCV dev team uses them for calibration purposes usually.
  2. You can use test images for OpenCV camera calibration module. It can be found in opencv_extra git repository in testdata/cv/cameracalibration folder.

Thanks Alexander. Under \opencv\samples\cpp threre are jpgs right01-right14 which may also help to test some code.
