data format for flyingthings3D

JerryLeolfl commented 3 years ago

Hi, thanks for your great work. I have a question when retrainning the model. Flow file in Flyingthins3D is in .ptm format, but the dataloader is set for .flo. Do you have a link for .flo flow data?

CXMANDTXW commented 3 years ago

I have meet the same problem, and I noticed that the size of optical flow file in the https://lmb.informatik.uni-freiburg.de/resources/datasets/SceneFlowDatasets.en.html#downloads is 364G, but the size of optical flow file downloaded by the link in this repo is 621G(full dataset size). Hope to get some help. By the way, I can not download the original file(torrent,75GB),because the download speed is always 0.

The dataset is really hard to download...But I have succeeded: link: https://pan.baidu.com/s/14PP68B3dayf7VNmeu9f5gg key: njl9

I really suffered from the downloading process... finally, I bought a data downloading service in taobao.com, and uploaded it to the Baidu cloud. Now everyone can download it for free.

Nice work! However, there is a small problem. The download speed is still only 60kb / s. It takes 21 hours to download a 4G file.

CXMANDTXW commented 3 years ago

It's so hard to download this dataset,even try from the baidupan. The download speed is so low, IDM(60kb/s),baidupan(8kb/s). I had to spend a month downloading this dataset, and I chose to give up.

littlespray commented 3 years ago

Maybe you can try their VIP...I am really frustrated with it : (, but it will have a nice speed.

CXMANDTXW commented 3 years ago

VIP solve every thing.Damned Baidu disk. Now,the download speed increased to 10MB/s. Thank you very much.

Hi, bro Is this the 75-G subdataset shown in https://lmb.informatik.uni-freiburg.de/resources/datasets/SceneFlowDatasets.en.html? I downloaded the 311G full file data, but folw file is saved in a .pfm format, which has 3 channels. But what the network output is a 2-channel .flo file, where we cannot caculate loss between them. I wonder if it is .flo format flow file in this 75G subset

littlespray commented 3 years ago

Yes. Actually many papers only use the subset for training. The 75G subset contains the .flo files you need. Also, the RGB images are in link: https://pan.baidu.com/s/1poQ-mrHK0U6cuBg5kp4gmA key: sj4d

JerryLeolfl commented 3 years ago

Yes, I have used this for training. But I found that there are a lot of invalid flow files with value 'nan'. Did you meet this problem? And do you have any way to solve it? I just overlook these data by an if function in code.

JerryLeolfl commented 3 years ago

Hi, have you used the dataset for training, It seems songthing wrong with the dataloader format provided, where it treats flow file flow[1] in into_future as a flow from im[1] to im[2]. what is your way to load the dataset?

AllenYLJiang commented 3 years ago

Dear littlespray,

Can you please share the disparity and disparity change parts of the flyingthings3d dataset? Thank you!

manfred-git commented 3 years ago

Thank you so much for sharing the dataset! It has bothered me for quite a long time. I think you made a great contribution for the community.

plateau1 commented 2 years ago

For the full dataset, can you provide its RGB image (clean and final)? Thank you very much！

shenjinyun commented 1 year ago

hello, I wonder if you have the subset disparity file, which is FlyingThings3D_subset_disparity.tar.bz2, I am suffering from downloading it, Thanks.
