The Tracker object registers the object tracks in the camera FOV during recording and saves them into in the VMDA metadata storage.

To configure the Tracker object, do the following:

Adjust
1. Configure the basic settings.
2. Optional:
add
3. configure a mask to disable analysis in any
part(s)
4. parts of the camera FOV.
5. Optional: set
detected object sizes
6. the size of the detected objects or configure the perspective settings (see Configuring perspective).

Basic settings

To configure the Tracker object, do the following:

1. Go to the Hardware tab in the System settings dialog
box
2. window.
3. In the
objects
4. object tree
in
5. on the Hardware tab, select the Camera object, corresponding to the camera, the video image from which you want to analyze.
6. Create the Tracker object on the

55. Go to the Basic settings tab (5).
56. In the Metadata sources table, set the checkboxes next to the objects used for metadata creation (6):
    
    1. Internal source. The resources of the Tracker object are used as the metadata source.

Tracker mask

To disable analysis in the area that is in the camera FOV, in you must click the Tracker Set mask tab button (12) , click on the Set Tracker mask button tab (21) and specify and specify the area in the video preview area. It is possible to You can disable analysis in several areas, i.e. to , that is, set several masks. To set an additional mask, click the the Set mask button again and specify an additional masked area in the video preview area.

To If, after clicking the Set mask button, you want to zoom in on the video preview field mask setting area for a more precise selection of the masked area, right-click the video preview area while holding down the Shift key on the keyboard after clicking the Set mask button. The video opens in a separate window, the size of which you can be resized change by dragging its borders. After setting you set the mask in this window, close it by clicking the  button button in the upper right corner.
