Equation 7 in the paper --> Camera intrinsics $ K $

Closed this issue · 1 comments

Hi, I find out that there seems to be a typo in your paper:
at Page 10, Section C.1, Equation 7, where the camera intrinsics $K$ is given as:

Should it be:

$$ K = \begin{bmatrix} fx & 0 & cx \\ 0 & fy & cy \\ 0 & 0 & 1 \end{bmatrix} $$

I have checked again, and there is only one version in arxiv site: https://arxiv.org/abs/2409.06765

Yeah I noticed this shortly after uploading... thanks for bringing it up. You are correct, the namings should be fx at index (0,0) and cy at index (2,1).
