cannot detect asymmetric circles calibration pattern
Most of the photos from this sample:link_to_sample_on_dropbox are not detected as containing asymmetric circles calibration pattern. It can see only IMG_0565.jpg IMG_0566.jpg IMG_0568.jpg IMG_0569.jpg. Videos from the same device (iPad 3) and of the same calibration pattern are detected fine. So, I wonder, what am I doing wrong?
Code for calibration script is taken unchanged from opencv-2.4.9/sample/cpp/calibration.cpp
Command line string: ./calibration -pt acircles -w 4 -h 11 imagelist.yaml
(also tried ./calibration -pt acircles -w 11 -h 4 imagelist.yaml)
imagelist.yaml is attached: imagelist.yaml.jpg (please remove suffix '.jpg')
My ideas: Maybe it is because of EXIF signature generated by iOS devices? Maybe camera orientation, while taking photos, matters?
