Control Panel

The control panel is located on the right side in the Zivid Studio GUI. It contains two sections:

  • Camera

  • Capture

Camera

This section is used to scan for, connect to, and disconnect from available cameras.


Camera Dropdown Options

Camera

Function

Scan for connected cameras

Show all cameras plugged into the PC and list them by model and serial number.

Connect

Connect to the camera selected in the drop-down menu. Zivid Studio can connect to a single camera at a time.

Disconnect from active camera

Disconnect from the active camera.

Capture

This section is used to capture 3D images. Here you can control and configure the camera settings. This section has two modes:

  • Assisted Mode

  • Manual Mode

Assisted Mode

This mode is the easiest to use.

  • Specify the maximum capture time

  • Click Analyze & Capture

This triggers the camera to analyze the scene and output the camera settings required to cover as much of the dynamic range in the scene as possible. Immediately after this, the camera performs a second capture using these settings.

  • The Capture button performs a capture with the settings suggested by the assisted capture, without additional scene analysis.


Ambient Light Adaptation is used when ambient light (AC powered) is mixed with the camera’s projector.

  • Select your power grid frequency from the drop-down menu. 60 Hz is typically used in Japan, Americas, Taiwan, South Korea, and the Philippines. 50 Hz is the normal in rest of the world.

Acquisition and filter settings appear at the bottom right corner of the “Capture” section after camera captures. It is possible to save all settings to disk.

  • Click on File → Export Capture Settings

  • Then click Save settings to folder

The folder needs to be empty. Settings can be loaded using the Zivid SDK.

Manual Mode

In the manual mode, users must configure all settings and filters manually.

Settings and Filters

Exposure Settings

Exposure Options

Setting

Function

Exposure Time

The duration a single camera image is exposed to light.

Aperture Step/F-number

The opening that controls the amount of light to the camera sensor through the lens.

Brightness

The output power (the amount of light) emitted by the LED projector.

Gain

The amplification of the signal from the camera sensor.

Filters

Filter Options

Setting

Function

Noise Removal

Remove points where the projected pattern signal-to-noise-ratio is below the specified threshold.

Outlier Removal

Remove points if the distance to their neighboring pixels within the small local region is larger than the threshold specified in mm.

Reflection Removal

Remove points impacted by reflections and thus erroneous.

Gaussian Smoothing

Perform Gaussian smoothing on the point cloud.

Contrast Distortion

Correct and/or remove points affected by blurring in the camera lens.

The color temperature of ambient light affects the appearance of the color image. Set the white balance by adjusting blue, green and red color balance to make color images look natural.

Single and Live Captures

  • The Single button captures a single acquisition with the specified settings, which is then displayed.

  • The Live button triggers continuous captures, which enables you to view the scene in real-time.


HDR

For high dynamic range scenes, it is necessary to use multi-acquisition HDR. In this mode, the camera captures one image per acquisition. Each image captured uses the settings configured for the specific acquisition. These images are then automatically merged into a single, high-quality HDR frame.

Once you select the manual mode, you can click the Add Acquisition button to add additional acquisitions. By default, each new acquisition added uses the settings of the previous acquisition. You can clone a specific acquisition by clicking on the three dots next to that acquisition and then on the Clone acquisition option. Use the same menu to reset acquisition settings or delete individual acquisitions. Disable or enable acquisitions with the checkbox.

  • Click the HDR button to capture an image with the acquisition settings specified; unchecked acquisitions are ignored by the capture.


You can also use the Assisted mode to get suggested settings, and then switch to the Manual mode to fine tune these settings manually.
