Confusion about code details. #13

Dear Tang, thank you for sharing the code for reproduction!

However, I am confused about the meaning of $K$ and $R$ in the function get_K_R() mentioned in line 93 of demo.py, and what is the purpose of this function. Can you provide some explanations for better understanding?

K, R = get_K_R(90, degree, 0, resolution, resolution).

Thank you for your time and looking forward to your reply. Best regards.

Hi, it converts degree to intrinsic matrix (K) and extrinsic matrix (R), and then you can use this matrix to compute correspondence.
