User Interface

The window of LumiScan VGR Engineering has four parts:

  • The configuration panel at the top holds the buttons that act on the configuration as a whole

    • save, reload, download, upload.

  • The graph overview at the bottom shows the elements of the configuration in their categories and how they are connected.

  • The preview panel on the left shows the element selected in the graph overview and how the current settings affect it.

  • The editor panel on the right shows the settings of the selected element and is where they are changed.

Configuration panel

The four buttons act on the entire configuration. Files can also be dropped onto the buttons instead of using Upload.

Save

Saves the current state of the settings.

Reload

Loads the last saved settings back into the user interface. Use it to revert unsaved changes.

Download

Downloads a .zip file that contains the settings in the format of LumiScan VGR Engineering and in the format used by LumiScan VGR or other compatible software.

Upload

Uploads a file into the configuration: either a .zip file that was downloaded from LumiScan VGR Engineering, which restores that configuration, or a file that the settings refer to, for example a .hdvcal camera calibration file.

Graph overview

The graph overview shows the elements of the configuration as columns, one per category, connected from left to right: a configured camera produces an image, an object detection consumes it, and the detection result is used to control a robot. Each category can hold several elements, and an element can be connected to several elements of the next category.

Select

Click an element. The preview and the editor switch to it.

Add

Type a unique ID into the id field at the bottom of the column and click Add.

Remove

Select the element and click the X that appears in its top-right corner.

Connect

Drag from the source element to the target element.

Disconnect

Double-click the connection. The mouse pointer changes when it is over a connection.

What the elements of each category contain is described under Configuration Elements.

Editor panel

The editor shows the settings of the element selected in the graph overview and is where they are edited. It has two views, switched with the buttons in its top-right corner:

  • Form - the settings as input fields with labels, grouped by topic.

  • Raw JSON - the same settings as JSON text.

Both views show exactly the same information and allow the same changes; use whichever suits the task.

Preview panel

The preview shows the element selected in the graph overview. What it shows depends on the type of the element, and it is updated whenever a setting that affects the element is changed. Many element types offer two views, switched with the buttons in the top-right corner of the preview:

  • Image - the camera image.

  • Point cloud - the 3D data, which can be navigated with the mouse:

    • drag with the left mouse button to rotate,

    • drag with the right mouse button to pan,

    • turn the mouse wheel to zoom.

The point cloud view also shows the coordinate system: a red, a green and a blue line mark the x, y and z axis. They start at the coordinate origin and each has a length of 1.
