Choosing an optics model and calibrating PTZ camera optics

In order to correctly position the PTZ camera in ActivePTZ mode and in order for a PTZ camera to operate properly as part of the ActiveDome module, the camera's optics must first be calibrated.

If your camera's model is in the "Select vendor" dropdown list, then simply select it from the list. Otherwise:

  1. Select "Any camera (Analyze Optics Model)" in the "Select vendor" dropdown list.
  2. Arrange the camera such that the image contains as many contrasting areas as possible.
  3. Click "Start".

    The automatic optics calibration process will begin (it may take several minutes). During the calibration process, the camera will be pointed at different points in the scene. When the calibration is complete, the grid will appear above the image along with a button to "Send optics model to DSSL"

Tip

Preferably, there should not be motion and external noise (rain, snow, swaying trees) in the camera's field of view during the optics analysis.

If you would like to help us improve our software, you can send your calibration results to DSSL over the Internet by clicking "Send optics model to DSSL". And dialog will open where you can enter the camera's manufacturer and model, and see exactly what information will be sent. Leave the default value in the "To be sent to" field. The information will be sent when you click "Send".

The additional setting "Limit zoom for ActivePTZ and ActiveDome" lets you control the camera's maximum zoom level. The default value is "0%" (no restriction). If the value "100%" is specified, the camera will rotate into the desired direction without any zoom.

Tip

To test the calibration results, try to direct the camera at several points in ActivePTZ mode.
