Note: due to upload size limit, pretrain model and checkpoint are not uploaded. Please refer to Model section for model download.

Requirement

• python 2.7
• torch 0.4.1
• torchvision 0.2.1
• scikit-learn 0.20.3
• numpy
• matplotlib
• tqdm
• tensorboardX

Dataset

Two datasets are used: Matterport and Scannet. Please refer to [this website] for data download.
After data download, please config the data path in config.json.

Model

Download the model and pretrain file from [Google Drive]

Demo

1. Please set up environment and download the model.
2. run demo_rgbd_mp.sh. Result will be saved in ./result/demo_rgbd_mp/
3. run demo_rgbd_sc.sh. Result will be saved in ./result/demo_rgbd_sc/

Usage

Please set the data path in config.json

Sample bash files can be found in ./sample_bash for training and testing. You may use them directly or follow the below instruction to make your own training/testing scripts.

To train/test on matterport,

1. training:

   • a. train RGB model with l1 loss (train_RGB.py)
   • b. train fusion network with map_conv (no hybrid, just l1 at final scale) use RGB model for RGB encoder several epoch will be okay (5~10)
   • c. use the model above as pretrained model, apply hybrid (5~10)

2. testing: run test_RGBD.py
   func eval_normal_pixel for evaluation metric computation
   Metric result saved in ./model_path/model_name.csv, as the below sequence:
   

   Mean error|Median error|Percentage of error less than 11.25°|22.5°|30°
   

   The average result is stored in the last row. For metric detail meaning, please refer to paper

To train/test on scannet

1. training:

   • a. train RGB model with l1 loss (train_RGB.py)
   • b. train fusion network with map_conv (train_RGBD_ms.py, no hybrid, just l1 at final scale) use RGB model for RGB encoder several epoch will be okay (5~10)
   • c. use the model above as pretrained model, apply hybrid(train_RGBD_ms.py,5~10 epoch)

2. testing: run test_RGBD_ms.py
   func eval_normal_pixel for evaluation metric computation
   Average metric result saved in ./model_path/model_name.csv

3. Additionally, run test_RGBD_ms_sc.py
   For object detail normal computation. Pixels belonging to bed, sofa, chair are computed separately
