Frequently Asked Questions

Camera connection

* Which type of camera is supported?

In Fotonic Viewer 1.1, Fotonic Astra/Astra S/Astra Pro, Microsoft Kinect v2, Fotonic E-series and Fotonic P60U cameras are supported.

* How do I connect a camera?

First start the Fotonic Viewer and physically connect the camera.

Switch to the “Cameras” dialog.

Press the button “Scan”. This will start a scan for any supported cameras and list the result.

Select one of the results and press “Connect” or double click in the list.

* How do I disconnect a camera?

Go to the “Cameras” dialog, select the camera and press “Disconnect” or double click in the list.

Camera settings

* How do I modify the exposure time and other internal settings of a connected camera?

All device-specific settings are shown in the “Device” dialog. To show the settings of a specific camera, click in one of the views showing a signal from that camera.

File saving and loading

* Which file types are supported?

Fotonic Viewer saves file sequences in the .pcd file format. (

Each frame is saved in one .pcd file, with its timestamp as name.

The save target is always a folder (not: a file). The folder needs to be empty before saving.

After a sequence has been saved, a settings.xml file is generated which contains information about the camera settings for each frame.

* How do I save data from a camera?

Connect a camera. Switch to the “File” dialog. Select the camera to save from in the “From Camera” drop-down.

Select a folder in the “To Folder”-field to save to. This folder needs to be empty.

Select the number of frames to save and press “Save”. A value “0” will save frames indefinitely, until manually stopped.

To stop saving before the specified number of frames has been reached, press “Stop Saving”.

* How do I load saved data?

Switch to the “File” dialog.

To add a new directory with saved files, press “Add New”. Select a directory containing .pcd-files, assign it an alias and press “Create”.

Under “Load”, all added file sequences are listed. These can all be thought of as separate cameras and can be loaded and played, one by one or simultaneously.

To load one of the directories in the list, select it and press “Load” or double click in the list.

* How do I control the playback of a saved sequence?

Each loaded file sequence is treated as an individual camera. Therefore, its settings can be found in the “Device”-dialog. Here you can pause or resume playback, select frame and set whether playback should restart once the end of the sequence is reached.

Viewer settings

* How do I split the window so I can show two different camera streams or one look at one camera stream from different angles simultaneously?

Click “Viewport Settings” under the “Window” menu. In the subsequently showing dialog you can define into how many parts the window should be split.

* I cannot see one of the dialogs you mentioned. How do I find it?

Dialogs can be hidden from the “Settings” menu.

They can also be rearranged and detached from the main window by clicking in their title bar and dragging them.

* How do I change which camera is being shown?

Switch to the “Viewer” dialog. Select the tab corresponding to the view where you want to switch camera.

Select whether to display the camera data as a 2D image or a 3D point cloud.

All available cameras show up as tabs. Click on a tab to activate that camera in the selected view.

Keep in mind that some camera types only are available in 2D mode.

* How do I change between RGB/Brightness/Distance modes?

Go to the “Viewer”-dialog and select a view and a camera. Switching between RGB, brightness and distance is done with the “Camera Output” buttons.

Note that the available options will vary depending on the camera type.

* How do I change the coloring in a view?

Go to the “Viewer”-dialog and select a view and a camera.

Select either “Distance” or “Brightness” as camera output mode. Select between “Color” or “Grayscale”, and specify a range with the “Scaling” sliders.

* How do I control the camera view?

You can always reset the view position by pressing “Zoom Extent” in the “Viewer”-dialog. This will position the view so that it shows the entire point cloud.

Known issues
