untar data

Hello,

Thanks for your great work. There is some problem when I untar your data, can I help to have a look?

Hello,

Thank you for the kind words about our project! Before I attempt to answer your question, let me provide some context. I had originally tarred the preprocessed data on CentOS Linux (Version 7), where the tar version was “tar (GNU tar) 1.26”.

After reading your github issue, I downloaded and untarred the database_humandog.tar.gz file in question on both Linux (CentOS 7) and Mac OS (13.0.1), using the commands bash download_preprocessed.sh; tar -xzvf database_humandog.tar.gz. I was able to successfully download and untar database_humandog.tar.gz for both cases, so I do not think this is an OS issue. However, the error message suggests that you were trying to untar the file from a BSD-based system (as opposed to a UID-based system such as Linux, which was the OS where I tarred the file in the first place). Therefore, I would recommend you to try adding the --numeric-owner flag to the untar command and see if it works:

tar -xzvf database_humandog.tar.gz --numeric-owner

Otherwise, try redownloading the tarred file and untar that instead. Let me know if you have any follow-up questions.

Hi,

Thanks for your reply. I guess it may be the problem with my SSD.
I have another question about the depth, in read_depth of vidbase.py, I notice that you reshape the depth to 256192. Why the shape of depth is like that rather than the same as the image shape (720960)? Thanks!

That is because the depth measurements provided by the iPad Pro has a resolution of 256 x 192. Later we resize it to be the same as the image shape (960x720) in vidbase.py https://github.com/andrewsonga/Total-Recon/blob/be22ad9e12739d26533e98b2cdab09f706e40a45/dataloader/vidbase.py#L162
