There are two main categories of samples: Camera and Applications. The samples in the Camera category focus only on how to use the camera. The samples in the Applications category use the output generated by the camera, such as the 3D point cloud, a 2D image or other data from the camera. These samples shows how the data from the camera can be used.

Windows
Launch the Command Prompt by pressing Win + R keys on the keyboard,
then type cmd and press Enter.
Navigate to a location where you want to clone the repository, then run to following command:
git clone https://github.com/zivid/zivid-cpp-samples
Configure the sample solution with CMake, open it in Visual Studio, build it, run it. For more information see Configure C++ Samples With CMake and Build Them in Visual Studio in Windows.
Ubuntu
Open the Terminal by pressing Ctrl + Alt + T keys on the keyboard.
Navigate to a location where you want to clone the repository, then run to following command:
git clone https://github.com/zivid/zivid-cpp-samples
cd zivid-cpp-samples
Build the project:
mkdir build
cd build
cmake <options, see below> ../source
make -j
Some of the samples depend on external libraries, in particular Eigen 3,
OpenCV, PCL, or HALCON. If you don't want to install those, you can
disable the samples depending on them by passing the following options,
respectively, to cmake: -DUSE_EIGEN3=OFF, -DUSE_OPENCV=OFF,
-DUSE_PCL=OFF, -DUSE_HALCON=OFF.
If you do want to use them:
- Eigen 3: Set
-DEIGEN3_INCLUDE_DIR=<path>where<path>is the root directory of your Eigen3 installation (the folder containing Eigen/Core, Eigen/Dense etc.) - PCL and OpenCV: If a recent enough version is installed on
your system, these should just work. If not, set
-DPCL_DIR=<path>/-DOpenCV_DIR=<path>where<path>is the directory containingPCLConfig.cmakeandOpenCVConfig.cmake, respectively. - HALCON: If a recent enough version is installed on your system, these should just work.
The samples can now be run from the build directory, for instance like this:
./CaptureFromFileCameraVis3D
If you want to use Zivid in HALCON, we provide a GenICam GenTL producer that comes with the Zivid Software.
Zivid and HALCON are compatible with Windows 10 and 11, and Ubuntu 20.04, 22.04, 24.04.
Note:
Support for Ubuntu 18.04 is removed since SDK 2.10.
To set up and use Zivid in one of these operating systems, please follow their respective instructions on the following pages:
- Install Zivid + HALCON for Windows
- Install Zivid + HALCON for LINUX
- Create a HALCON "Hello World" Program
- How to Run a HALCON Sample
- Debug in HALCON
- HALCON Sample Videos
The following HALCON versions have been tested and confirmed to work with Zivid cameras:
- 19.05 Progress, 20.05 Progress, 21.11 Progress
We recommend using one of the HALCON versions we have tested.
For more information about the Zivid cameras, please visit our Knowledge Base. If you run into any issues please check out Troubleshooting.

To run continuous integration locally, use Docker. With Docker installed, run this command:
docker run -it -v <unix-style-repo-path>:/host -w /host/continuous-integration/linux ubuntu:20.04
Where <unix-style-repo-path> is the unix-style path to the repo on
your computer. On Linux, use $PWD for this. On Windows you need to
translate the windows-style path to a unix-style one (e.g.
/c/Users/alice/Documents/zivid-cpp-samples).
Now run ./setup.sh to install dependencies. Once setup has completed,
you can run ./lint.sh && ./build.sh repeatedly to check your code.
Tip:
If your build hangs, try to increase the memory available to Docker.
