Evaluation
You can evaluate by executing the following command:
- MatterportLayout dataset
python main.py --cfg src/config/mp3d.yaml --mode test --need_rmse
- ZInd dataset
python main.py --cfg src/config/zind.yaml --mode test --need_rmse
- PanoContext dataset
python main.py --cfg src/config/pano.yaml --mode test --need_cpe --post_processing manhattan --force_cube
- Stanford 2D-3D dataset
python main.py --cfg src/config/s2d3d.yaml --mode test --need_cpe --post_processing manhattan --force_cube
--post_processing
type of post-processing approach, we use DuLa-Net post-processing and optimize by adding occlusion detection (described in here ) to processmanhattan
constraint (manhattan_old
represents the original method), use DP algorithm to processatalanta
constraint, default is disabled.--need_rmse
need to evaluate root mean squared error and delta error, default is disabled.--need_cpe
need to evaluate corner error and pixel error, default is disabled.--need_f1
need to evaluate corner metrics (Precision, Recall and F$_1$-score) with 10 pixels as threshold(code from here), default is disabled.--force_cube
force cube shape when evaluating, default is disabled.--wall_num
different corner number to evaluate, default is all.--save_eval
save the visualization evaluating results of each panorama, the output results locate in the corresponding checkpoint directory (e.g.,checkpoints/SWG_Transformer_LGT_Net/mp3d/results/test
), default is disabled.
Training
Execute the following commands to train (e.g., MatterportLayout dataset):
python main.py --cfg src/config/mp3d.yaml --mode train
You can copy and modify the configuration in YAML
file for other training.
Inference
We provide an inference script (inference.py
) that you can
try to predict your panoramas by executing the following command (e.g., using pre-trained weights of MatterportLayout dataset):
python inference.py --cfg src/config/mp3d.yaml --img_glob src/demo/demo1.png --output_dir src/output --post_processing manhattan
It will output json files(xxx_pred.json
, format is the same as PanoAnnotator) and visualization images (xxx_pred.png
) under output_dir.
visualization image:
-
--img_glob
a panorama path or directory path for prediction. -
--post_processing
Ifmanhattan
is selected, we will preprocess the panorama so that the vanishing points are aligned with the axes for post-processing. Note that after preprocessing our predicted results will not align with your input panoramas, you can use the output file (vp.txt
) of vanishing points to reverse align them manually. -
--visualize_3d
3D visualization of output results (need install dependencies and GUI desktop environment). -
--output_3d
output the object file of 3D mesh reconstruction.
