Installation

Environment

  • Ubuntu 16.04
  • python 3.6
  • CUDA 10.1

Requirements:

You can install the requirements by running pip install -r requirements.txt.

If you use other versions of PyTorch or CUDA, be sure to select the corresponding version of torch_scatter.

Data Preparation

Download dataset

The raw data can be found in SSCNet.

The repackaged data can be downloaded via Google Drive or BaiduYun(Access code:lpmk).

The repackaged data includes:

rgb_tensor   = npz_file['rgb']		# pytorch tensor of color image
depth_tensor = npz_file['depth']	# pytorch tensor of depth 
tsdf_hr      = npz_file['tsdf_hr']  	# flipped TSDF, (240, 144, 240)
tsdf_lr      = npz_file['tsdf_lr']  	# flipped TSDF, ( 60,  36,  60)
target_hr    = npz_file['target_hr']	# ground truth, (240, 144, 240)
target_lr    = npz_file['target_lr']	# ground truth, ( 60,  36,  60)
position     = npz_file['position']	# 2D-3D projection mapping index

Train and Test

Configure the data path in config.py

'train': '/path/to/your/training/data'

'val': '/path/to/your/testing/data'

Train

Edit the training script run_SSC_train.sh, then run

bash run_SSC_train.sh

Test

Edit the testing script run_SSC_test.sh, then run

bash run_SSC_test.sh

Visualization and Evaluation
