For the precise tracking of the object under observation, you must calibrate the telemetry device by matching at least six telemetry device positions with the frame points of each overview camera.

Attention!

  • The recommended number of points that must be set is 6-10. If you add more points, the algorithm will be configured more precisely. However, this increases the chance that some of the points are set up incorrectly, which causes the decrease of the operation quality.
  • The points set in the calibration setting must not be on the same line for both the overview and the PTZ camera. It is recommended to set the points for both cameras so that they evenly cover the entire frame.
  • The calibration points must be set on the same surface (floor, ground). It is not recommended to set the points on different surfaces (for example, when some points are on the ground, and other points are on a tree, etc.).

To calibrate the telemetry device, do the following:

  1. Select the overview camera from the list (see Linking panoramic cameras to a PTZ camera).
  2. Focus the PTZ camera on any point. To do this, in the preview window click the button and change the orientation of the lens in one of the following ways:
    1. Left-click on the frame and holding the button, move the mouse cursor in the required direction.
    2. Use the Point&Click function (see Control using Point&Click).

  3. Left-click to add a point to the frame of the overview camera to which the PTZ camera is currently oriented.

Attention!

The object under observation must be inside the frame of the PTZ camera.

4. Repeat the process to set at least 6 points.
5. Repeat the process for all overview cameras (select the camera by clicking in the list of the overview cameras).
6. Click the Apply button to save the calibration points.

Calibration of the telemetry device is complete.

It is recommended to perform a calibration check after calibration is complete. To do this, do the following:

  1. Click the button to the right of the preview window of the overview camera.

  2. Click on different points in the image of the overview camera. If the PTZ camera is positioned correctly, the calibration is correct.

Note

To delete the calibration points, click the button.
