Note

This repository contains TensorFlow and PyTorch implementations of BTS.

Preparation for all implementations

$ cd ~
$ mkdir workspace
$ cd workspace
### Make a folder for datasets
$ mkdir dataset
### Clone this repo
$ git clone https://github.com/cleinc/bts

Prepare NYU Depth V2 test set

$ cd ~/workspace/bts/utils
### Get official NYU Depth V2 split file
$ wget http://horatio.cs.nyu.edu/mit/silberman/nyu_depth_v2/nyu_depth_v2_labeled.mat
### Convert mat file to image files
$ python extract_official_train_test_set_from_mat.py nyu_depth_v2_labeled.mat splits.mat ../../dataset/nyu_depth_v2/official_splits/

Prepare KITTI official ground truth depth maps

Download the ground truth depthmaps from this link KITTI.
Then,

$ cd ~/workspace/dataset
$ mkdir kitti_dataset && cd kitti_dataset
$ mv ~/Downloads/data_depth_annotated.zip .
$ unzip data_depth_annotated.zip

Follow instructions from one of the below implementations with your choice.

Note: Modify arguments '--encoder', '--model_name', '--checkpoint_path' and '--pred_path' accordingly.

Live Demo

Finally, we attach live 3d demo implementations for both of TensorFlow and Pytorch.
For best performance, get correct intrinsic values for your webcam and put them in bts_live_3d.py.
Sample usage for PyTorch:

$ cd ~/workspace/bts/pytorch
$ python bts_live_3d.py --model_name bts_nyu_v2_pytorch_densenet161 \
--encoder densenet161_bts \
--checkpoint_path ./models/bts_nyu_v2_pytorch_densenet161/model \
--max_depth 10 \
--input_height 480 \
--input_width 640
