Quick Capture Tutorial

Introduction

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

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 settings = Zivid::Settings(settingsFile);

C#

source

var settings = new Zivid.NET.Settings(settingsFile);

Python

source

settings = zivid.Settings.load(settings_file)

Capture

C++

source

const auto frame = camera.capture2D3D(settings);

C#

source

using (var frame = camera.Capture2D3D(settings))

Python

source

with camera.capture_2d_3d(settings) as frame:

Save

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)

Export

C++

source

const auto dataFilePLY = "PointCloud.ply";
frame.save(dataFilePLY);

C#

source

var dataFilePLY = "PointCloud.ply";
frame.Save(dataFilePLY);

Python

source

data_file_ply = "PointCloud.ply"
frame.save(data_file_ply)

For other exporting options, see Point Cloud for a list of supported formats

Utilize

C++

source

const auto pointCloud = frame.pointCloud();
const auto data = pointCloud.copyData<Zivid::PointXYZColorRGBA>();

C#

source

var pointCloud = frame.PointCloud;
var pointCloudData = pointCloud.CopyPointsXYZColorsRGBA();

Python

source

point_cloud = frame.point_cloud()
xyz = point_cloud.copy_data("xyz")
rgba = point_cloud.copy_data("rgba")

Tip

1. You can export Preset settings to YML from Zivid Studio

2. 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.
