Capture Tutorial

Introduction

This tutorial describes how to use the Zivid SDK to capture point clouds and 2D images.

For MATLAB see Zivid Capture Tutorial for MATLAB.

Tip

If you prefer watching a video, our webinar Making 3D captures easy - A tour of Zivid Studio and Zivid SDK covers the same content as the Capture Tutorial.

Prerequisites

Initialize

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

Note

Zivid::Application must be kept alive while operating the Zivid Camera. This is essentially the Zivid driver.

Go to source

source

Zivid::Application zivid;
Go to source

source

var zivid = new Zivid.NET.Application();
Go to source

source

app = zivid.Application()

Connect

Now we can connect to the camera.

Go to source

source

auto camera = zivid.connectCamera();
Go to source

source

var camera = zivid.ConnectCamera();
Go to source

source

camera = app.connect_camera()

Specific Camera

Sometimes multiple cameras are connected to the same computer, but it might be necessary to work with a specific camera in the code. This can be done by providing the serial number of the wanted camera.

auto camera = zivid.connectCamera(Zivid::CameraInfo::SerialNumber{ "2020C0DE" });
var camera = zivid.ConnectCamera(new Zivid.NET.CameraInfo.SerialNumber("2020C0DE"));
camera = app.connect_camera(serial_number="2020C0DE")

Note

The serial number of your camera is shown in the Zivid Studio.

You may also list all cameras connected to the computer, and view their serial numbers through

Go to source

source

auto cameras = zivid.cameras();
std::cout << "Found " << cameras.size() << " cameras" << std::endl;
for(auto &camera : cameras)
{
    std::cout << "Camera Info: " << camera.info() << std::endl;
}
Go to source

source

var cameras = zivid.Cameras;
Console.WriteLine("Number of cameras found: {0}", cameras.Count);
foreach (var camera in cameras)
{
    Console.WriteLine("Camera Info: {0}", camera.Info);
}
Go to source

source

cameras = app.cameras()
for camera in cameras:
    print(f"Camera Info:  {camera}")

File Camera

The file camera option allows you to experiment with the SDK without access to a physical camera. The file cameras can be found in Sample Data where there are multiple file cameras to choose from. Each file camera demonstrates a use case within one of the main applications of the respective camera model. The example below shows how to create a file camera using the Zivid Two M70 file camera from Sample Data.

Go to source

source

const auto fileCamera =
    userInput ? fileCameraPath : std::string(ZIVID_SAMPLE_DATA_DIR) + "/FileCameraZividTwoM70.zfc";
Go to source

source

fileCamera = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "/Zivid/FileCameraZividTwoM70.zfc";
Go to source

source

default=get_sample_data_path() / "FileCameraZividTwoM70.zfc",
Go to source

source

auto camera = zivid.createFileCamera(fileCamera);
Go to source

source

var camera = zivid.CreateFileCamera(fileCamera);
Go to source

source

camera = app.create_file_camera(file_camera)

The acquisition settings should be initialized like shown below, but you are free to alter the processing settings.

Go to source

source

const auto settings =
    Zivid::Settings{ Zivid::Settings::Acquisitions{ Zivid::Settings::Acquisition{} },
                     Zivid::Settings::Processing::Filters::Smoothing::Gaussian::Enabled::yes,
                     Zivid::Settings::Processing::Filters::Smoothing::Gaussian::Sigma{ 1.5 },
                     Zivid::Settings::Processing::Filters::Reflection::Removal::Enabled::yes,
                     Zivid::Settings::Processing::Filters::Reflection::Removal::Experimental::Mode::global,
                     Zivid::Settings::Processing::Color::Balance::Red{ 1 },
                     Zivid::Settings::Processing::Color::Balance::Green{ 1 },
                     Zivid::Settings::Processing::Color::Balance::Blue{ 1 } };
Go to source

source

var settings = new Zivid.NET.Settings
{
    Acquisitions = { new Zivid.NET.Settings.Acquisition { } },
    Processing = { Filters = { Smoothing = { Gaussian = { Enabled = true, Sigma = 1.5 } },
                               Reflection = { Removal = { Enabled = true, Experimental = { Mode = ReflectionFilterModeOption.Global} } } },
                   Color = { Balance = { Red = 1.0, Green = 1.0, Blue = 1.0 } } }
};
Go to source

source

settings = zivid.Settings()
settings.acquisitions.append(zivid.Settings.Acquisition())
settings.processing.filters.smoothing.gaussian.enabled = True
settings.processing.filters.smoothing.gaussian.sigma = 1
settings.processing.filters.reflection.removal.enabled = True
settings.processing.filters.reflection.removal.experimental.mode = "global"
settings.processing.color.balance.red = 1.0
settings.processing.color.balance.green = 1.0
settings.processing.color.balance.blue = 1.0

You can read more about the file camera option in File Camera.

Configure

As with all cameras there are settings that can be configured. These may be set manually, or you use our Capture Assistant.

Capture Assistant

It can be difficult to know what settings to configure. Luckily we have the Capture Assistant. This is available in the Zivid SDK to help configure camera settings.

Go to source

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);
Go to source

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);
Go to source

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)

There are only two parameters to configure with Capture Assistant:

  1. Maximum Capture Time in number of milliseconds.

    1. Minimum capture time is 200 ms. This allows only one acquisition.

    2. The algorithm will combine multiple acquisitions if the budget allows.

    3. The algorithm will attempt to cover as much of the dynamic range in the scene as possible.

    4. A maximum capture time of more than 1 second will get good coverage in most scenarios.

  2. Ambient light compensation

    1. May restrict capture assistant to exposure periods that are multiples of the ambient light period.

    2. 60Hz is found in Japan, Americas, Taiwan, South Korea and Philippines.

    3. 50Hz is common in the rest of the world.

Manual configuration

Another option is to configure settings manually. For more information about what each settings does, please see Camera Settings. Note that Zivid Two has a set of standard settings.

Single Acquisition

We can create settings for a single acquisition capture.

Go to source

source

const auto settings =
    Zivid::Settings{ Zivid::Settings::Experimental::Engine::phase,
                     Zivid::Settings::Acquisitions{ Zivid::Settings::Acquisition{
                         Zivid::Settings::Acquisition::Aperture{ 5.66 },
                         Zivid::Settings::Acquisition::ExposureTime{ std::chrono::microseconds{ 6500 } } } },
                     Zivid::Settings::Processing::Filters::Outlier::Removal::Enabled::yes,
                     Zivid::Settings::Processing::Filters::Outlier::Removal::Threshold{ 5.0 } };
Go to source

source

var settings = new Zivid.NET.Settings
{
    Acquisitions = { new Zivid.NET.Settings.Acquisition { Aperture = 5.66,
                                                          ExposureTime =
                                                              Duration.FromMicroseconds(6500) } },
    Processing = { Filters = { Outlier = { Removal = { Enabled = true, Threshold = 5.0 } } } }
};
Go to source

source

settings = zivid.Settings()
settings.experimental.engine = "phase"
settings.acquisitions.append(zivid.Settings.Acquisition())
settings.acquisitions[0].aperture = 5.66
settings.acquisitions[0].exposure_time = datetime.timedelta(microseconds=6500)
settings.processing.filters.outlier.removal.enabled = True
settings.processing.filters.outlier.removal.threshold = 5.0

Multi Acquisition HDR

We may also create settings to be used in a multi-acquisition HDR capture.

Go to source

source

Zivid::Settings settings;
for(const auto aperture : { 11.31, 5.66, 2.83 })
{
    std::cout << "Adding acquisition with aperture = " << aperture << std::endl;
    const auto acquisitionSettings = Zivid::Settings::Acquisition{
        Zivid::Settings::Acquisition::Aperture{ aperture },
    };
    settings.acquisitions().emplaceBack(acquisitionSettings);
}
Go to source

source

var settings = new Zivid.NET.Settings();
foreach (var aperture in new double[] { 9.57, 4.76, 2.59 })
{
    Console.WriteLine("Adding acquisition with aperture = " + aperture);
    var acquisitionSettings = new Zivid.NET.Settings.Acquisition { Aperture = aperture };
    settings.Acquisitions.Add(acquisitionSettings);
}
Go to source

source

settings = zivid.Settings(acquisitions=[zivid.Settings.Acquisition(aperture=fnum) for fnum in (11.31, 5.66, 2.83)])

Fully configured settings are demonstrated below.

2D Settings

It is possible to only capture a 2D image. This is faster than a 3D capture. 2D settings are configured as follows.

    Zivid::Settings2D{ Zivid::Settings2D::Acquisitions{ Zivid::Settings2D::Acquisition{

Load

Zivid Studio can store the current settings to .yml files. These can be read and applied in the API. You may find it easier to modify the settings in these (human-readable) yaml-files in your preferred editor.

Go to source

source

const auto settingsFile = "Settings.yml";
std::cout << "Loading settings from file: " << settingsFile << std::endl;
const auto settingsFromFile = Zivid::Settings(settingsFile);

Console.WriteLine("Loading settings from file: " + settingsFile);
var settingsFromFile = new Zivid.NET.Settings(settingsFile);
Go to source

source

settings_file = "Settings.yml"
print(f"Loading settings from file: {settings_file}")
settings_from_file = zivid.Settings.load(settings_file)

Save

You can also save settings to .yml file.

Go to source

source

const auto settingsFile = "Settings.yml";
std::cout << "Saving settings to file: " << settingsFile << std::endl;
settings.save(settingsFile);
Go to source

source

var settingsFile = "Settings.yml";
Console.WriteLine("Saving settings to file: " + settingsFile);
settings.Save(settingsFile);
Go to source

source

settings_file = "Settings.yml"
print(f"Saving settings to file: {settings_file}")
settings.save(settings_file)

Caution

Zivid settings files must use .yml file extension ( not .yaml).

Capture

Now we can capture a 3D image. Whether there is a single acquisition or multiple acquisitions (HDR) is given by the number of acquisitions in settings.

Go to source

source

const auto frame = camera.capture(settings);
Go to source

source

using (var frame = camera.Capture(settings))
Go to source

source

with camera.capture(settings) as frame:

The Zivid::Frame contains the point cloud and color image (stored on compute device memory) and the capture and camera information.

The Zivid.NET.Frame contains the point cloud and color image (stored on compute device memory) and the capture and camera information.

The zivid.Frame contains the point cloud and color image (stored on compute device memory) and the capture and camera information.

Load

Once saved, the frame can be loaded from a ZDF file.

Go to source

source

const auto dataFile = std::string(ZIVID_SAMPLE_DATA_DIR) + "/Zivid3D.zdf";
std::cout << "Reading ZDF frame from file: " << dataFile << std::endl;
const auto frame = Zivid::Frame(dataFile);
Go to source

source

var dataFile =
    Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "/Zivid/Zivid3D.zdf";
Console.WriteLine("Reading ZDF frame from file: " + dataFile);
var frame = new Zivid.NET.Frame(dataFile);
Go to source

source

data_file = get_sample_data_path() / "Zivid3D.zdf"
print(f"Reading point cloud from file: {data_file}")
frame = zivid.Frame(data_file)

Saving to a ZDF file is addressed later in the tutorial.

Capture 2D

If we only want to capture a 2D image, which is faster than 3D, we can do so via the 2D API.

Go to source

source

const auto frame2D = camera.capture(settings2D);
Go to source

source

using (var frame2D = camera.Capture(settings2D))
Go to source

source

with camera.capture(settings_2d) as frame_2d:

Caution

Zivid One+ camera has a time penalty when changing the capture mode (2D and 3D) if the 2D capture settings use brightness > 0. You can read more about it in 2D and 3D switching limitation.

Save

We can now save our results.

Go to source

source

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

source

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

source

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

Tip

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

Export

The API detects which format to use. See Point Cloud for a list of supported formats. For example, we can export the point cloud to .ply format.

Go to source

source

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

source

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

source

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

Save 2D

We can get 2D color image from a 3D capture.

Go to source

source

const auto image = pointCloud.copyImageRGBA();

2D captures also produce 2D color images.

Go to source

source

const auto image = frame2D.imageRGBA();
Go to source

source

var image = frame2D.ImageRGBA();
Go to source

source

image = frame_2d.image_rgba()

Then, we can save the 2D image.

Go to source

source

const auto imageFile = "Image.png";
std::cout << "Saving 2D color image to file: " << imageFile << std::endl;
image.save(imageFile);
Go to source

source

var imageFile = "Image.png";
Console.WriteLine("Saving 2D color image to file: {0}", imageFile);
image.Save(imageFile);
Go to source

source

image_file = "Image.png"
print(f"Saving 2D color image to file: {image_file}")
image.save(image_file)

Multithreading

Operations on camera objects are thread-safe, but other operations like listing cameras and connecting to cameras should be executed in sequence. Find out more in Multithreading.

Conclusion

This tutorial shows how to use the Zivid SDK to connect to, configure, capture, and save from the Zivid camera.
