This is the error I get when I run the sample calibration code from the official documentation link samples/cpp/tutorial_code/calib3d/camera_calibration/
what(): /home/manohar/opencv-3.1.0/modules/core/src/convert.cpp:5475: error: (-215) src.size == dst.size && src.channels() == dst.channels() in function cvConvertScale
I entered the correct number of squares and other required details. Please help me with this, Thanks in advance.
