title: OpenCV C++ Stereo Calib Example
body: <p>I want to run the OpenCv Stereo Calib sample. But I have a error message like "<strong>0 pairs have been successfully detected. Error: too little pairs to run the calibration</strong> "</p>
  
  <p>I created a folder under data folder. It's name is Stereo. And there is a pair of image like 1.jpg and 2.jpg in the stereo folder. When I run the program I have error message mentioned above.</p>
  
  <p>You can see my pictures in the attachment.</p>
  
  <p>What should I do? How can I run this example?</p>
