About

APD-MVS is an MVS method that adopts adaptive patch deformation and an NCC-based matching metric.

Our paper was accepted by CVPR 2023!

Dependencies

The code has been tested on Ubuntu 18.04 with Nvidia Titan RTX, and you can modify the CMakeList.txt to compile on Windows.

• Cuda >= 10.2
• OpenCV >= 3.3.0
• Boost >= 1.62.0
• cmake >= 2.8

Besides make sure that your GPU Compute Capability matches the CMakeList.txt!!! Otherwise you won't get the depth results! For example, according to GPU Compute Capability, RTX3080's Compute Capability is 8.6. So you should set the cuda compilation parameter 'arch=compute_86,code=sm_86' or add a '-gencode arch=compute_86,code=sm_86'.

Usage

Compile APD-MVS

git clone https://github.com/whoiszzj/APD-MVS.git
cd APD-MVS
mkdir build & cd build
cmake ..
make

Prepare Datasets

ETH Dataset

You may download train and test dataset from ETH3D, and use the script colmap2mvsnet.py to convert the dataset format(you may refer to MVSNet). You can use the "scale" option in the script to generate any resolution you need.

python colmap2mvsnet.py --dense_folder <ETH3D data path, such as ./ETH3D/office> --save_folder <The path to save> --scale_factor 2 # half resolution

Tanks & Temples Dataset

We use the version provided by MVSNet. The dataset can be downloaded from here, and the format is exactly what we need.

Other Dataset

Such as DTU and BlenderMVS, you may explore them yourself. !!! But remember to modify the ReadCamera function when you test on DTU !!!

Run

After you prepare the dataset, and you want to run the test for ETH3D/office, you can follow this command line.

./APD <ETH3D root path>/office

The result will be saved in the folder office/APD, and the point cloud is saved as "APD.ply"

It is very easy to use, and you can modify our code as you need.
