Wrong Intrinsics #64

Closed zjrandom951 closed 3 months ago

zjrandom951 commented 3 months ago

There seems to be an issue with the camera's intrinsics, some focal is 0.

Was an image transposed fromportrait to landscape? It seems the intrinsics matrices rows are simply permuted as expected when transposing from portrait to landscape as in https://github.com/naver/dust3r/blob/main/dust3r/datasets/base/base_stereo_view_dataset.py#L202

when i try to run the training script, if the image resulotion is not square, then there is a probability that the diagonal element of the camera's intrinsics matrix is 0

thanks, it should be because the image was transposed.
