Could you offer the camera_calibration.txt file?

@Emanuele97x Hi, I found that you load the camera_calibration.txt in ViPCDataLoader_ft class when training the model in weakly supervised manner. However, I don't have this file at all.

Could you offer this file? Thanks in advance.

Hi! @zhanghm1995
These files are present in the view folder in the dataset, just for the objects we use for the weakly supervised training (you can find them in train_list_clean_.....txt files). Hope you find it!

Best,

Emanuele

Hi, @Emanuele97x I'm not sure whether I missed something. I cannot find this file after extracting the dataset as below.

And from your descriptions, I wonder are the camera parameters same for all objects or different for each object?

[Ema97]

They are inside the folder of each specific object, indeed if you look at the dataloader for each object we extract camera_calibration.txt and rendering_metadata.txt.

@Emanuele97x , sorry to ask you again. I don't know why I cannot find the camera_calibration.txt in my original extracted dataset,

,

I guess these files maybe exist in your ShapeNetViPC-PartPart.tar.gz file, and I'm downloading it at the same time to see what's wrong. In this case, I wonder to know how to generate the camera_calibration.txt file for the whole ShapeNet-ViPC dataset.

The file is present only for the selected obects, please check train_list_clean_plane.txt for an example.

@Emanuele97x , so it means we can only obtain the camera_calibration.txt in those selected objects? Is there any way to get the camera parameters for all objects?
