Available Views

There are five views available at the bottom of Zivid Studio. These views show the following features:

• The point cloud

• The color image

• The depth map

• The SNR map

• The normal map

To navigate between views you can either

• Use the keyboard shortcuts 1 through 5

• Change manually at the bottom of the GUI by clicking on the thumbnails

• Select from the drop-down menu in the top left corner

Point Cloud

This view displays the point cloud of the scene after a 3D capture or after loading a ZDF file.

• Use the left mouse button to rotate the point cloud.

• Use the right mouse button to pan.

• Zoom in or out by rolling the mouse wheel or, if available, by the middle mouse button followed by dragging the mouse.

Turning color (C, D and R) and mesh (M) on and off in this view helps evaluate the point cloud quality. The point size is also adjustable through the drop-down menu at the top left. Adjusting the point size is for example helpful for inspecting areas where textures are important. If you have enabled the Region Of Interest, you can also modify the visibility of this in the drop-down menu.

Color

This view displays the color image of the scene after a 2D capture or after loading a ZDF file.

• Position the mouse pointer over a pixel in the image to get image coordinates and RGB values. The pixel values are displayed in the status bar in the bottom left corner of the window.

• Zoom in or out by rolling the mouse wheel or, if available, by the middle mouse button followed by dragging the mouse.

• Use the left mouse button to pan the view.

When doing a 2D+3D capture with different pixel sampling you can switch between the 2D image from the 2D capture and 3D capture in the top-left drop-down.

Depth

This view displays the depth image of the scene after a capture or after loading a ZDF file.

• Position the mouse pointer over a pixel in the image to get image coordinates, XYZ values, and SNR values. The pixel values are displayed in the status bar in the bottom left corner of the window.

• Use the drop-down menu located at the top left corner of the view to modify the Z range.

• Use zoom and pan functionalities in the same way as described in the Color View.

The color scale represents the distance variation along the z-axis from the camera to the surfaces of the imaged objects. To modify the range along the z-axis, you can use a fixed Z range in the top-left drop-down to narrow the color scale.

Signal-to-Noise-Ratio

This view displays the SNR map of the scene after a capture or after loading a ZDF file.

• Position the mouse pointer over a pixel in the image to get image coordinates and SNR values. The pixel values are displayed in the status bar in the bottom left corner of the window.

• Use zoom and pan functionalities in the same way as described in the Color View.

The color scale represents the variation in the SNR values. A pixel found at the higher end of the color scale represents a point associated with strong signal quality. For a point associated with a pixel found at the lower end of the color scale the ratio is more influenced by noise. Hence, these points involves higher uncertainty.

For a detailed explanation, see the SNR values Article.

Normals

This view displays the normal map of the scene after a capture or after loading a ZDF file.

• Position the mouse pointer over a pixel in the image to get image coordinates, normal coordinates, and SNR values. The pixel values are displayed in the status bar in the bottom left corner of the window.

• Use zoom and pan functionalities in the same way as described in the Color View.

The normal map provides a 2D representation of the surface normals of a scene where RGB color components describe the normal vectors. It is helpful in inspecting surface curvatures, surface textures, and transitions between objects as the color gradients describe these well.

For an introduction to normals, see the Normals Article.
