Content and Copyright
--------------------------------

This software package PlaneSweepLib (PSL) contains a C++/CUDA implementation of plane sweeping stereo matching for pinhole and fisheye images.
The package comes with test data and scripts to run the software on the test data.
It was tested on Linux using the GCC Toolchain and on Windows using Visual Studio.

Prerequisites
--------------------------------

The code is written in C++ and CUDA. To use it you need a CUDA compatible Nvidia GPU.
The following libraries are required:

GCC Toolchain on Linux
Visual Studio C++ on Windows
CMake
Nvidia CUDA
Boost (system filesystem program_options)
OpenCV
Eigen3


Instructions Linux
-----------------------------

To compile the code open a terminal and cd to the root directory PlaneSweepLib of the package and run:

mkdir build
cd build
cmake ..
make

The package comes with test data and applications that show how to use the plane sweep code.
To run the tests on the provided data cd to the root directory PlaneSweepLib of the package and run:

sh runPinholePlanesweepTestsLinux.sh
sh runFisheyePlanesweepTestsLinux.sh

The results are written to the folder PlaneSweepLib/testResults.
To check if the code runs correctly reference results are provided in the folder PlaneSweepLib/referenceTestResults


Instructions Windows
---------------------------------

Open a command prompt and cd to the root directory PlaneSweepLib of the package and run:

mkdir build
cd build
cmake -G "Visual Studio 10 Win64" ..    (Replace "Visual Studio 10 Win64" with your version, cmake without arguments provides a list.
                                        Alternatively use cmake-gui to generate the project files.)
                                             
Open the project file PlaneSweepLib/build/PSL.sln with Visual Studio and compile the whole solution in Release mode.


The package comes with test data and applications that show how to use the plane sweep code.
To run the tests on the provided data go to the command prompt and cd to the root directory PlaneSweepLib of the package and run:

runPinholePlanesweepTestsWindows.bat
runFisheyePlanesweepTestsWindows.bat

The results are written to the folder PlaneSweepLib/testResults.
To check if the code runs correctly reference results are provided in the folder PlaneSweepLib/referenceTestResults
