The RAPter gives us a very nice design and implementation for doing man-made scene reconstruction. According to the nature of its algorithm, it also shows a potential use in terms of 3D plane detection. However, the documentation related to it is pretty poor, so I decided to write here a summary of how to install it on Ubuntu 16.04 LTS.
Workspace
The first thing is to create a workspace directory in the user’s home directory and a 3rdparty subdirectory under workspace. Thus we can define the workspace path WORKSPACE_DIR as $ENV{HOME}/workspace and the third party dependencies path THIRD_PARTY_DIR as ${WORKSPACE_DIR}/3rdparty. In the following steps, we will store all the implementations of RAPter tools and experimental data in workspace and download all the dependencies in 3rdparty.
Dependencies
RAPter requires several dependencies, including OpenCV, PointCloudLibrary, CoinBonmin, and libfbi. Prior to downloading and installing all these dependences, we need to first get prepared with a few tools, including Git, SVN, and CMake via the following commands.
|
|
OpenCV
To install the latest version of OpenCV, we can use the installation script here. We first download this script in the 3rdparty directory, and then execute:
|
|
Type the sudo password and OpenCV will be installed.
PointCloudLibrary
There is no ready-made script for PointCloudLibrary, so the installation of it could be a bit tedious.
Setup Prerequisites
The PointCloudLibrary also needs a bunch of prerequisite tools. We use the commands below to have them set up.

|
Build PointCloudLibrary
In the 3rdparty directory, PointCloudLibrary is obtained by:
|
|
Now we get into pcl, create a release directory in it, and then follow the cmake build process.
|
|
Once the build is finished, we install it by:
|
|
CoinBonmin
As usual, we need to install the prerequisites:
|
|
Then we download CoinBonmin in 3rdparty:
|
|
CoinBonmin also requires a third party solver. To get it, we have to first go to the directory CoinBonmin-stable/ThirdParty/Mumps and run:
|
|
To compile and install CoinBonmin, we have to go back to the root directory of it, which is CoinBonmin-stable, and create a build directory in it, then run the cmake process.
|
|
libfbi
We only have to download libfbi in 3rdparty, no prerequisites or installation is required.
|
|
Compilation
Finally, all the dependencies are satisfied. We first get the RAPter in the workspace directory:
|
|
Then get into the root of RAPter, which is RAPter/RAPter, and build it.
|
|
Besides, we may also need to change the default directories of dependencies in CMakelist.txt. For example, following this article, the directory of PointCloudLibrary PCL_DIR should be ${THIRD_PARTY_DIR}/pcl/ instead of ${THIRD_PARTY_DIR}/pcl-trunk2/install/share/pcl-1.8/.
