Vectorized Indoor Surface Reconstruction from 3D Point Cloud with Multistep 2D Optimization

Introduction

This is the implementation of VecIM (ISPRS JPRS 2021), a multistep and versatile indoor LoD2 vectorized reconstruction pipeline without the Manhattan or Atlanta world assumptions. The core idea behind this method is the combination of a sequence of 2D segment or cell assembly problems defined as global optimizations while reducing the reconstruction complexity. For more details, please refer to the following paper:

Run VecIM

Dependencies

• CGAL (v4.11 has been tested)
• OPENCV (v3.4.3 has been tested)
• GLOG
• MPRF
• GMP

Build

The project is built on CMake, and there is more than one way to compile it. The following is an example on Linux or macOS system:

$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make

Run

For a certain scene, the permanent structures including facade, floor, ceiling and cylinder (if any) are first segmented from the whole point cloud in the pre-processing. VecIM takes the point cloud of different components as the input and outputs a LoD2 indoor vectorized model.

Put different semantic point cloud (facade.ply, floor.ply, ceiling.ply, cylinder.ply) and parameter configuration file in the same folder with the path PATH, and then run:

./Facade/Facade PATH

An example of parameter configuration file is provided named as config_modeling.xml.
