Tag&Track configuration

The Tag&Track function allows the PTZ camera to follow an object based on the trajectories obtained by the usual camera using the Tracker object. Thus, to use this function, you must first create and configure the following objects in Axxon PSIM:

1. The PTZ camera (see Configuring PTZ IP cameras).
2. The usual (stationary) camera with a tracker (see Configuring IP devices and Creating and configuring the Tracker object).
   

To configure the Tag&Track function, do the following:

1. Create the Tag&Track object on the basis of the Camera object (not the PTZ camera!).
   

   Note

   If a camera is linked with the PTZ device, you cannot create the Tag&Track object. If you first create this object and then link a camera with the PTZ device, the settings for changing the Tag&Track object are unavailable.
   

2. From the PTZ drop-down list, select the PTZ device object linked with the corresponding PTZ camera that is used for object tracking (1).

   

3. In the Auto switch (s): field (2), enter the time period in seconds after which you want to automatically switch to the next object in the automatic Tag&Track mode.

4. Select a line in the table (3). To do that, left-click any cell in the line.
   

   Note

   You can sort lines by one of the specified parameters. To do this, click the name of the corresponding column.

5. Click the Edit button (4). The Settings window opens.
   If you skip step 3 and don't select a line in the table, the Settings window doesn't open and the message "String not selected" is displayed.
   
   

   Note

   • For calibration, you can use the video with a low resolution, so the display quality in the Settings window can differ from the original video from a camera.
   • In this window, you can display a video in the separate window and increase the size of this window to the required one. To do this, right-click the video while holding down the Shift key on the keyboard. You can perform the same operations with video in the separate window as in the Settings window.
     
6. Click the required point on the image from the stationary camera (on the left). As a result, the coordinates of this point are specified in the X and Y fields (5). The point on the image is highlighted with a red square.
   
7. Rotate the PTZ camera (on the right) so that the cross that is in the center points at the same point as selected on the stationary camera. Use the Up, Down, Left, Right buttons to control a camera, and the + and - buttons to zoom in and out (6).
8. In the Rate field (7), set the moving speed of the PTZ camera lens. Possible values are from 1 to 10, the default value is 1.
9. Click the Request PTZ button (8).
10. The PAN, TILT, ZOOM fields are filled in with the corresponding PTZ camera coordinates (9).
11. If the check is required, click the Send to PTZ button (10). As a result, a camera is positioned to the obtained coordinates.
12. Click the OK button (11). The specified coordinates are displayed in the table on the Tag&Track object settings panel.
13. Repeat steps 4-11 at least five times for different points on the video. We recommend setting as many points as possible. 
    

14. Click the Apply button.
    

    Note

    When you set too few points, or in some other cases when points aren't set properly and the algorithm cannot process them, the "Invalid calibration" message is displayed when you click the Apply button.

    

    In this case, click the OK button and add or edit the points.

Configuring the Tag&Track function is complete.
