MVS-Texturing

Welcome to our project that textures 3D reconstructions from images. This project focuses on 3D reconstructions generated using structure from motion and multi-view stereo techniques, however, it is not limited to this setting.

The algorithm was published in Sept. 2014 on the European Conference on Computer Vision. Please refer to our project website (http://www.gcc.tu-darmstadt.de/home/proj/texrecon/) for the paper and further information.

Please be aware that while the interface of the texrecon application is relatively stable the interface of the tex library is currently subject to frequent changes.

Dependencies

The code and the build system have the following prerequisites:

• cmake (>= 3.1)
• git
• make
• gcc (>= 5.0.0) or a compatible compiler
• libpng, libjpg, libtiff, libtbb

Furthermore the build system automatically downloads and compiles the following dependencies (so there is nothing you need to do here):

• rayint https://github.com/nmoehrle/rayint
• Eigen http://eigen.tuxfamily.org
• Multi-View Environment http://www.gcc.tu-darmstadt.de/home/proj/mve
• mapMAP http://www.gcc.tu-darmstadt.de/home/proj/mapmap

Compilation

1. git clone https://github.com/nmoehrle/mvs-texturing.git
2. cd mvs-texturing
3. mkdir build && cd build && cmake ..
4. make (or make -j for parallel compilation)

If something goes wrong during compilation you should check the output of the cmake step. CMake checks all dependencies and reports if anything is missing.

If you think that there is some problem with the build process on our side please tell us.

If you are trying to compile this under windows (which should be possible but we haven't checked it) and you feel like we should make minor fixes to support this better, you can also tell us.

Execution

As input our algorithm requires a triangulated 3D model and images that are registered against this model. One way to obtain this is to:

• import images, infer camera parameters and reconstruct depth maps using the [Multi-View Environment] (http://www.gcc.tu-darmstadt.de/home/proj/mve/), and
• fuse these depth maps into a combined 3D model using the [Floating Scale Surface Reconstruction] (http://www.gcc.tu-darmstadt.de/home/proj/fssr/) algorithm.

A quick guide on how to use these applications can be found on our project website.

By starting the application without any parameters and you will get a description of the expected file formats and optional parameters.

Troubleshooting

When you encounter errors or unexpected behavior please make sure to switch the build type to debug e.g. cmake -DCMAKE_BUILD_TYPE=DEBUG .., recompile and rerun the application. Because of the computational complexity the default build type is RELWITHDEBINFO which enables optimization but also ignores assertions. However, these assertions could give valuable insight in failure cases.
