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++

source

Zivid::Application zivid;

C#

source

var zivid = new Zivid.NET.Application();

Python

source

app = zivid.Application()

Connect

C++

source

auto camera = zivid.connectCamera();

C#

source

var camera = zivid.ConnectCamera();

Python

source

camera = app.connect_camera()

Configure

C++

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);

C#

source

var suggestSettingsParameters = new Zivid.NET.CaptureAssistant.SuggestSettingsParameters {
    AmbientLightFrequency =
        Zivid.NET.CaptureAssistant.SuggestSettingsParameters.AmbientLightFrequencyOption.none,
    MaxCaptureTime = Duration.FromMilliseconds(1200)
};

Console.WriteLine("Running Capture Assistant with parameters:\n{0}", suggestSettingsParameters);
var settings = Zivid.NET.CaptureAssistant.Assistant.SuggestSettings(camera, suggestSettingsParameters);

Python

source

suggest_settings_parameters = zivid.capture_assistant.SuggestSettingsParameters(
    max_capture_time=datetime.timedelta(milliseconds=1200),
    ambient_light_frequency=zivid.capture_assistant.SuggestSettingsParameters.AmbientLightFrequency.none,
)

print(f"Running Capture Assistant with parameters: {suggest_settings_parameters}")
settings = zivid.capture_assistant.suggest_settings(camera, suggest_settings_parameters)

Capture

C++

source

const auto frame = camera.capture(settings);

C#

source

using(var frame = camera.Capture(settings))

Python

source

with camera.capture(settings) as frame:

Save

C++

source

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

C#

source

var dataFile = "Frame.zdf";
frame.Save(dataFile);

Python

source

data_file = "Frame.zdf"
frame.save(data_file)

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.
