Can I reduce kitti_Raw data for training ? about penet_icra2021

[JUGGHM]

Hi Laihu:
Thanks for your interest! The files are loaded in kitti_loader.py. And the paths are written in function get_paths_and_transform(split, args) . You could explicitly maintain a path list and only load files in the list, i.e. replace the *_sync in line51 with 2011_09_26_drive_0001_sync or other directories. I hope this might help!

Thanks, JUGGHM for the quick reply, I think you misunderstand my question as I request about kitti_raw data, not kitti_depth.
Kindly guide me through this issue, as all know Kitti_raw dataset is very huge, and out of 5 dates of data, I have 3 dates. like 2011_09_26 , 2011_09_28 and 2011_09_30.

The paths of corresponding RGB images are obtained via the function get_rgb_paths(p). So I think they are actually the same.

Thank you very much, JUGGHM. As you said path is the same.

Hello, thank you very much for your research. How to get_ rgb_ Paths (P) is modified to reduce the data set. Thank you for your patience

For example, you could include fewer images by modifying the * in the following code (involving all files/directories) into elements in a pre-defined list corresponding to some subset.
glob_d = os.path.join( args.data_folder, 'data_depth_velodyne/train/*_sync/proj_depth/velodyne_raw/image_0[2,3]/*.png' )

您好，非常感谢您的回复。麻烦再打扰问您一下，如果我想训练数据时，只用2011_9_26的raw  data来训练，不是kitti depth来训练，如何进行修改，可以详细说一下吗，很抱歉打扰到您了，希望得到您的回复

您好，KITTI上深度图补全中稀疏深度图都在kitti_depth中，raw里面只有彩色图，所以我不是很理解如何只用彩色图进行补全；如果要做单目深度估计的话，这部分代码需要重新组织。原始代码的逻辑是先从kitti_depth中读取深度图，再根据深度图文件名去raw中获取对应的彩色图像。

好的，非常感谢您

hello, I want to know how to change RGB images path if I have only 2011_09_26.

I think you could change as following:
From
'data_depth_velodyne/train/*_sync/proj_depth/velodyne_raw/image_0[2,3]/*.png'
to
'data_depth_velodyne/train/2011_09_26_*_sync/proj_depth/velodyne_raw/image_0[2,3]/*.png'
for all similar formatted paths in the dataloader.

Hello, thank you very much for your research. The kitti data set is relatively large, because my computing power is not enough (only 2080ti*2), so I want to use part of the data set for training, for example, there is a five-day data set, can I only use a one-day data set, please guide me How to reduce the dataset for training, looking forward to your reply.Thank you for your patience.
