I have run the code and got "terminate called after throwing an instance of 'DeficientImagesException'", then I find it only supporting jpg or png in line 47, mono.cpp

disk.zip I have got a reproject error 0.0558, but Calibration Quality: 68.656589 %. As in other issue, the problem is that I did not take photos at diffrent distances? Is there any literature tell us how to make better photos?

@spdfghi Could you tell me the length of the circle radius and distance?

spdfghi commented 1 month ago

@chaehyeonsong r=0.45 and d=1, board is here: diskboard.pdf made by mathematica code

@spdfghi . I examined the dataset. The main problem is deficient images. You need to extend the image sets I recommend to include closer scenes and farther scenes (closer scenes are important). Moreover, increase the circle radius and decrease the number of circles. (3x5 grid might be appropriate in your case)

@chaehyeonsong Thanks, I will try. And could you provide a more theoretical explanation for why? In the papers I have read, it is mentioned that the calibration distance and measurement distance should be close
