Quick Capture Tutorial

Introduction

This tutorial describes the most basic way to use the Zivid SDK to capture point clouds.

For MATLAB see Zivid Quick Capture Tutorial for MATLAB

Prerequisites

• Install Zivid Software.

• For Python: install zivid-python

Initialize

Calling any of the APIs in the Zivid SDK requires initializing the Zivid application and keeping it alive while the program runs.

C++C#Python

source

Zivid::Application zivid;

Connect

C++C#Python

source

auto camera = zivid.connectCamera();

Configure

C++C#Python

source

const auto suggestSettingsParameters = Zivid::CaptureAssistant::SuggestSettingsParameters{
    Zivid::CaptureAssistant::SuggestSettingsParameters::AmbientLightFrequency::none,
    Zivid::CaptureAssistant::SuggestSettingsParameters::MaxCaptureTime{ std::chrono::milliseconds{ 1200 } }
};

std::cout << "Running Capture Assistant with parameters:\n" << suggestSettingsParameters << std::endl;
auto settings = Zivid::CaptureAssistant::suggestSettings(camera, suggestSettingsParameters);

Capture

C++C#Python

source

const auto frame = camera.capture(settings);

Save

C++C#Python

source

const auto *dataFile = "Frame.zdf";
frame.save(dataFile);

The API detects which format to use. See Point Cloud for a list of supported formats.

Tip

You can open and view Frame.zdf file in Zivid Studio.

Conclusion

This tutorial shows the most basic way to use the Zivid SDK to connect to, capture, and save from the Zivid camera.
