preprocessing problems?

[NIRVANALAN]

Hi! I am trying to do inference on my own dataset. I wonder why you do intrinsics[:2, :] /= 4 in Dataset Class?

Hello, The predicted depth map is a quarter of the input image in each dimension. The camera intrinsic is corresponding to the input image.

🤩 thanks for your elaboration!

hi, when training, why you not do intrinsics[:2, :] /= 4 in Dataset Class, but do in eval.py?

@UestcJay if you have a closer look at the camera .txt files of the training and evaluation set respectively, you'll find that for the training dataset, the camera intrinsics were already transformed according to intrinsics[:2, :] /=4 before being stored in the .txt files. For the validation set, this is not the case. Hence, this correction must only be done through the data loader during validation. As a take-away, you'll most likely have to add intrinsics[:2, :] /=4 if you're loading your own data
