Introduction

This repository is the code implementation of the paper RSBuilding: Towards General Remote Sensing Image Building Extraction and Change Detection with Foundation Model, which is based on the Open-cd project.

The current branch has been tested under PyTorch 2.0.1 and CUDA 11.7, supports Python 3.7+, and is compatible with most CUDA versions.

If you find this project helpful, please give us a star ⭐️, your support is our greatest motivation.

1. Installation

Dependencies

• Linux
• Python 3.7+, recommended 3.9
• PyTorch 2.0 or higher, recommended 2.0
• CUDA 11.7 or higher, recommended 11.7
• MMCV 2.0 or higher, recommended 2.0

Install RSBuilding

Download or clone the RSBuilding repository.

git clone git@github.com:Meize0729/RSBuilding.git
cd RSBuilding

Environment Installation

We recommend using Miniconda for installation. The following command will create a virtual environment named rsbuilding and install PyTorch and MMCV.

Note: If you have experience with PyTorch and have already installed it, you can skip to the next section. Otherwise, you can follow these steps to prepare.

Tips: We recommend installing the version that has been practically tested and proven to work.

Step 0: Install Miniconda.

Step 1: Create a virtual environment named rsbuilding and activate it.

conda create --name rsbuilding python=3.9
conda activate rsbuilding

Step 2: Install PyTorch, we recommend using conda to install the following version:

conda install pytorch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2 pytorch-cuda=11.7 -c pytorch -c nvidia

Step 3: Install MMCV. We recommend using pip to install the following version:

pip install mmcv==2.0.1 -f https://download.openmmlab.com/mmcv/dist/cu117/torch2.0/index.html -i https://pypi.tuna.tsinghua.edu.cn/simple

Step 4: Install other dependencies.

pip install -r requirements.txt

2. Dataset Preparation

We provide the dataset preparation method used in the paper. Data preparation and preprocessing can be somewhat time-consuming. You may choose to work with only the datasets you wish to use.

You can access detailed preprocessing instructions at the following location:

cd tools/data_process.md

✅ Upon completing all the data preprocessing steps along this path, I trust that the train.txt and test.txt files within your data_list folder for the datasets you plan to use have been accurately populated with the absolute paths.

3. Model Training

The entire training process involves: Pretrain ➡️ Finetune on specific datasets.

We provide the configuration files of the models used in the paper, which can be found in the configs_pretrain and configs_finetune folder. The Config file is completely consistent with the API interface and usage method of MMsegmentation. If you want to know more about the meaning of the parameters, you can refer to the MMSegmentation documentation.

Pretrain

We offer configuration files for four different backbone models. The pre-training process can be skipped as we have released our pre-trained weights.

During the pre-training process, the training will be conducted on the datasets listed in data_list/pretrain/train.txt. You can add or remove any dataset as needed, while monitoring the metrics using the datasets shown in data_list/pretrain/test.txt.

Step1: During the pre-training phase, we require the pre-trained weights of the backbone for initialization. You can obtain the pre-trained weights for the Swin series here, and for the ViT series here, or find specific download links in configs_pretrain/__base__/models/xxx.py. We have not included the preprocessing code for the pre-trained weights in this repository, but it is straightforward to handle.

❗️Step2❗️: After downloading the pre-trained weights for backbone, you need to replace Line 32 in configs_pretrain/xxx.py with the specific path. Meanwhile, change the Line 41 to the location where you want to save the training logs and weights.

Step3: And then, use following command to train your own model:

# Single-Card Training
python tools/train.py configs_pretrain/xxx.py  # xxx.py is the configuration file you want to use

# Multi-Card Training
sh ./tools/dist_train.sh configs_pretrain/xxx.py ${GPU_NUM}  # xxx.py is the configuration file you want to use, GPU_NUM is the number of GPUs used

Finetune

Step1: Download the pre-trained model from following link: Baidu NetDisk (The access code: rsmz). If you use your own pre-trained weights, you can ignore the above steps. But we are sorry, we are not yet able to release all pre-trained weights publicly.

❗️Step2❗️: After downloading the pre-trained weights, you need to replace Line 33 in configs_finetune/***/xxx.py with the specific path. Meanwhile, change the Line 41 to the location where you want to save the training logs and weights.

Step3: And then, use following command to train your own model or use the command specified in the configuration file to start the training:

# Single-Card Training
python tools/train.py configs_finetune/xxx.py  # xxx.py is the configuration file you want to use

# Multi-Card Training
sh ./tools/dist_train.sh configs_finetune/xxx.py ${GPU_NUM}  # xxx.py is the configuration file you want to use, GPU_NUM is the number of GPUs used

4. Model Testing

After you have obtained the fine-tuned model weights on a specific dataset, you can perform metric testing using the following command.

# Single-Card Testing
python tools/test.py configs_finetune/***/xxx.py ${CHECKPOINT_FILE} # xxx.py is the configuration file you want to use, CHECKPOINT_FILE is the checkpoint file you want to use

# Multi-Card Testing
sh ./tools/dist_train.sh configs_finetune/***/xxx.py ${CHECKPOINT_FILE} ${GPU_NUM}  # xxx.py is the configuration file you want to use, CHECKPOINT_FILE is the checkpoint file you want to use, GPU_NUM is the number of GPUs used
