Sample list

There are two main categories of samples: Camera and Applications. The samples in the Camera category focus only on how to use the camera.

Instructions

1. Install Zivid Software

2. Download Zivid Sample Data

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
cmake --build .

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.

See Configure C++ Samples With Optional Dependencies for instructions on how to install the optional dependencies and configure the samples to use them.

The samples can now be run from the build directory, for instance like this:

./CaptureFromFileCameraVis3D
