Configure C++ Samples With Optional Dependencies

This tutorial shows how to configure optional dependencies for the Zivid C++ Samples with CMake.

Requirements

Optional requirements

Some of the samples depend on external libraries, in particular:

참고

The following instructions have been tested with these versions of the dependencies:

  • Visual Studio 2019 and higher

  • CMake 3.24 and higher

  • PCL 1.12.1

  • Eigen 3.4.0

  • OpenCV 4.7.0

Install Eigen 3 from the package manager by running:

sudo apt install libeigen3-dev

Navigate to the build directory you created in zivid-cpp-samples and run

mkdir build
cd build
cmake -DEIGEN3_INCLUDE_DIR=/usr/include/eigen3 -DUSE_OPENCV=OFF -DUSE_PCL=OFF -DUSE_OPEN3D=OFF ../source
cmake --build .

Install PCL from the package manager by running:

sudo apt install libpcl-dev

Navigate to the build directory you created in zivid-cpp-samples and run

mkdir build
cd build
cmake -DUSE_PCL=ON -DUSE_EIGEN3=OFF -DUSE_OPENCV=OFF -DUSE_OPEN3D=OFF ../source
cmake --build .

Install OpenCV from the package manager by running:

sudo apt install libopencv-dev clang-tidy

Navigate to the build directory you created in zivid-cpp-samples and run

mkdir build
cd build
cmake -DUSE_OPENCV=ON -DUSE_EIGEN3=OFF -DUSE_PCL=OFF -DUSE_OPEN3D=OFF ../source
cmake --build .

Download and install prebuilt Open3D binaries from https://github.com/isl-org/Open3D/releases.

For version 0.19.0, download the tarball from https://github.com/isl-org/Open3D/releases/download/v0.19.0/open3d-devel-linux-x86_64-cxx11-abi-0.19.0.tar.xz

The tarball contains a folder named open3d-devel-linux-x86_64-cxx11-abi-0.19.0. Copy the contents of this folder to /usr/local.

You can do this in one go by running the following command in the terminal:

sudo tar --strip-components=1 -xvf ./open3d-devel-linux-x86_64-cxx11-abi-0.19.0-C /usr/local

Navigate to the build directory you created in zivid-cpp-samples and run

mkdir build
cd build
cmake -DUSE_OPEN3D=ON -DUSE_EIGEN3=OFF -DUSE_OPENCV=OFF -DUSE_PCL=OFF ../source
cmake --build .

Download the latest stable release of Eigen from http://eigen.tuxfamily.org/ and extract the folder to your desired destination. When configuring the CMake project, include Eigen to configure the samples that depend on it.

Navigate to the build directory you created in zivid-cpp-samples and run

cmake -DEIGEN3_INCLUDE_DIR=<path> -DUSE_OPENCV=OFF -DUSE_PCL=OFF -DUSE_EIGEN3=OFF ../source

where <path> is the full path to where you installed Eigen, e.g. C:/Program Files/Eigen.

In CMake GUI, click Add Entry to add the path to Eigen. Add EIGEN3_INCLUDE_DIR and point the value to where you extracted the folder.

Screenshot of CMake GUI where you can enter Eigen 3 include directory.

Ensure that the box USE_EIGEN3 is checked and click Configure. Then click Generate and Open Project to open the Visual Studio solution.

Download and install prebuilt PCL binaries by choosing the .exe at https://github.com/PointCloudLibrary/pcl/releases. Check the option to install 3rd Party Libraries.

Screenshot of PCL installation wizard on Windows.

Some settings must be included in the PATH system variable before you can configure the Zivid PCL code samples. On your PC, navigate to Control PanelSystem and SecuritySystemAdvanced System SettingsEnvironment Variables. Under System variables, select the Path variable and click Edit.

Screenshot of system information on Windows.

In the Edit environment variable window, click New and add the paths to the PCL binaries and OpenNI2 (3rd party library), e.g.

C:\Program Files\PCL 1.12.1\bin
C:\Program Files\OpenNI2\Tools

if you have installed PCL 1.12.1 and OpenNI2 in Program Files. You may have to sign out of your Windows account and in again for the changes to take place.

You may have to manually link to some of the third-party PCL libraries, like VTK. If you encounter errors, add the path to the binaries of the library in the PATH system variable. E.g. for VTK, you would add C:/Program Files/PCL 1.12.1/3rdParty/VTK/bin if you installed PCL 1.12.1 in Program Files.

When configuring the CMake project, the paths to PCL should already be configured.

Navigate to the build directory you created in zivid-cpp-samples and run

cmake -DUSE_PCL=ON -DUSE_EIGEN3=OFF -DUSE_OPENCV=OFF ../source

In CMake GUI, ensure that the box USE_PCL is checked and click Configure.

Click Generate and Open Project to open the Visual Studio solution.

Download and install prebuilt OpenCV binaries from https://opencv.org/releases/. Extract them to your desired destination, e.g.

C:\Users\Public

Some settings must be included in the PATH system variable before you can configure the Zivid OpenCV code samples. On your PC, navigate to Control PanelSystem and SecuritySystemAdvanced System SettingsEnvironment Variables. Under System variables, select the Path variable and click Edit.

Screenshot of system information on Windows.

In the Edit environment variable window, click New and add the path to the OpenCV binaries, e.g.

C:\Program Files\opencv\build\x64\vc16\bin

if you have installed OpenCV 4.7.0 and extracted it to C:/Program Files/opencv.

When configuring the CMake project, include OpenCV to configure the samples that depend on it.

Navigate to the build directory you created in zivid-cpp-samples and run

cmake -DOpenCV_DIR=<path> -DUSE_EIGEN3=OFF -DUSE_PCL=OFF ../source

where <path> is the full path to the OpenCV build folder, e.g. C:/Program Files/opencv/build.

In CMake GUI, click Add Entry to add the path to OpenCV. Add OpenCV_DIR and point the value to the OpenCV build folder.

Ensure that the box USE_OPENCV is checked and click Configure. Then click Generate and Open Project to open the Visual Studio solution.

You need Halcon installed on your PC to run the Halcon C++ samples. Go to Install Zivid + HALCON for Windows for further instructions.

After you have installed Halcon, configure CMake to use Halcon samples.

Navigate to the build directory you created in zivid-cpp-samples and run

cmake -DUSE_HALCON=ON -DUSE_EIGEN3=OFF -DUSE_OPENCV=OFF -DUSE_PCL=OFF -DUSE_OPEN3D=OFF ../source

Ensure that the box USE_HALCON is checked and click Configure.

Then click Generate and Open Project to open the Visual Studio solution.

Download and install prebuilt Open3D binaries from https://github.com/isl-org/Open3D/releases. Open3D does not support multi-configuration builds, so you must choose which to configure for.

Extract them to your desired destination, e.g.

C:\Program Files\Open3D
C:\Program Files\Open3D-Debug

In order for CMake to find Open3D you must do one of the following:

  • set the CMAKE_INSTALL_PREFIX variable to point to the folder containing the CMake folder, or you must

  • set the Open3D_DIR variable to point to the folder containing the Open3DConfig.cmake file

Navigate to the build directory you created in zivid-cpp-samples and run

cmake -DUSE_OPEN3D=ON -DCMAKE_INSTALL_PREFIX=<path-to-open3d> -DUSE_EIGEN3=OFF -DUSE_OPENCV=OFF -DUSE_PCL=OFF ../source

where <path-to-open3d> is the path to the Open3D folder, e.g. C:/Program Files/Open3D.

Add to CMAKE_INSTALL_PREFIX or set Open3D_DIR variable to point to the Open3D folder.

Ensure that the box USE_OPEN3D is checked and click Configure.

../../../_images/cmake_gui_screenshot_add_open3d.png

Then click Generate and Open Project to open the Visual Studio solution.

In order to run the Open3D samples, you must add the Open3D binary folder to your PATH environment variable.

If you want to configure multiple dependencies at once, you can simply add multiple dependencies at the same time in CMake. For example, if you want to use all samples that require Eigen and Open3D, you can run

mkdir build
cd build
cmake -DEIGEN3_INCLUDE_DIR=/usr/include/eigen3 -DUSE_OPEN3D=ON -DUSE_PCL=OFF -DUSE_OPENCV=OFF ../source
cmake -DEIGEN3_INCLUDE_DIR=<path-to-eigen> -DUSE_OPEN3D=ON -DCMAKE_INSTALL_PREFIX=<path-to-open3d> -DUSE_PCL=OFF -DUSE_OPENCV=OFF ../source

where <path-to-open3d> is the path to the Open3D folder, e.g. C:/Program Files/Open3D.
