Configuring the camera

If an image source is a camera, you can use a live image from the camera in the Defect Detection Station App to position the camera and make camera setting adjustments.

Note

The Station App refreshes the image every 500 milliseconds.

The settings you can change are:

• gain — increases the brightness of the images output by the camera. The value you enter is the raw gain value for the camera. The default value is 10.

• exposure — The amount of time, in milliseconds, that the image sensor is exposed to light when capturing an image. The default value is 4000.

• gstreamer — Station App uses the gstreamer library to capture images from a camera, and make them available for analysis with your model, or for adding to a dataset. The default settings are video/x-bayer, format=bggr ! bayer2rgb ! video/x-raw, format=RGBA. For more information, see gstreamer.

Configure the camera (Station App)

To configure the camera (Station App)

1. Open the Station App on your edge device by opening a browser and navigating to x.x.x.x:3000. For x.x.x.x, use the IP address of your edge device.

2. On the left menu of the application, choose Management and then Image sources.

3. In Images sources, choose the image source with the camera that you want to configure. If you don't have an image source, do Adding an image source.

4. Choose the Image capture tab.

5. In the Image preview section, turn on Live preview. The preview image is updated every 500ms.

6. Decide if the image from the camera is acceptable.

   You can use the following commands to pan and zoom the image.

   • Pan image — Choose the pan button ( ). Click and hold the mouse button and then drag the mouse to pan across the image.

   • Zoom image — Zoom in an out of the image with the zoom in button ( ) and the zoom out button . Double-click the image to zoom 2x into to the image. Use the mouse scroll wheel to zoom in and out of the image. The mouse cursor position is the center position for zooming (in or out).

   • Reset image size — Choose the reset button ( ) or press Ctrl + 0.

   If you need to make changes, choose Edit image settings to make changes. You can adjust the Gain and Exposure values.

   To make Gstreamer setting changes, do the following:

   1. Choose Advanced settings.

   2. In the Gstreamer pipeline edit box, enter the changes that you want to make.

   3. Choose Apply to apply your changes. To reset to the default values, choose Reset.

   Changes are immediately saved to the camera. Use the preview image to confirm that the changes are acceptable.

   Choose Save to save your changes.

7. Next step: Collecting images for your datasets.
