3DCDNet-Urb3DCD

The experimental code of 3DCDNet on Urb3DCD dataset

Requirement

python 3.7.4
torch 1.8.10
visdom 0.1.8.9
torchvision 0.9.0

Urb3DCD Dataset

The Urb3DCD Dataset can be found from ( I. de Gélis, S. Lefèvre, and T. Corpetti, “Change Detection in Urban Point Clouds: An Experimental Comparison with Simulated 3D Datasets,” Remote Sensing, vol. 13, no. 13, p. 2629, Jul. 2021, doi: 10.3390/rs13132629.)

Pretrained Model

The pretrained model fro Urb3DCD is available at [Google Drive] and [Baiduyun] (the password is: txx5).

Test

Before test, please download datasets and pretrained models. Change path to your data path in configs.py. Copy pretrained models to folder './outputs_{sub_dataset_names}/best_weights', and run the following command:

cd 3DCDNet_ROOT
python test.py

Training

Before training, please download datasets and revise dataset path in configs.py to your path.

cd 3DCDNet_ROOT
python -m visdom.server
python train.py

To display training processing, open 'http://localhost:8097' in your browser.
