NOTE: To build this project, you will need the Point Clouds Library (PCL) from "http://pointclouds.org/".

Linux: export OpenCV_DIR="~/OpenCV/build" mkdir build cd build cmake -D OpenCV_DIR=$OpenCV_DIR .. make

MacOSX (Xcode): export OpenCV_DIR="~/OpenCV/build" mkdir build cd build cmake -G Xcode -D OpenCV_DIR=$OpenCV_DIR .. open ExploringSfMWithOpenCV.xcodeproj

Windows (MS Visual Studio): set OpenCV_DIR="C:\OpenCV\build" mkdir build cd build cmake -G "Visual Studio 9 2008" -D OpenCV_DIR=%OpenCV_DIR% .. start ExploringSfMWithOpenCV.sln
