Configuring the VIT module

Configure the VIT program module as follows:

1. Go to the Hardware tab in the System settings dialog window (1).
2. Select the VIT module object, corresponding to the set VIT program module in the objects tree in the Hardware tab (2). The settings panel of the selected object will open on the right of the window.
   

3. Set the Zooming checkbox checked to increase the plate recognizing speed on mega-pixel video cameras without loss of recognizing quality (3).

   Note

   This check box is relevant when the value of the Zone width parameter is more than 150 pixels (see Setting up the LPR channel detector section). The recognizing speed is increasing:

   • 2 times if the value of the Zone width parameter is more than 150 pixels;
   • 4 times if the value of the Zone width parameter is more than 400 pixels;
   • 8 times if the value of the Zone width parameter is more than 800 pixels.
4. If there is frame loss during recognition when mega-pixel video cameras are in use, then the frame loss can be compensated by increasing the maximum number of recognition streams. For this change the value of the Number of streams for frame processing field (4):
   

   1. If the value of the Number of streams for frame processing field is 0,recognition will be performed in the same stream it was started. It is the default value.

   2. If the value of the Number of streams for frame processing field is 1, recognition will be performed in the parallel stream to the process that starts it. This is the recommended value.

   3. If the value of the Number of streams for frame processing field is 2, recognition will be performed in two streams simultaneously to the process that starts it. But in this case 2 licenses are in use.
      
      

5. Perform fine tuning of SDK if required (5, see VIT module object settings panel)

6. Click Apply to save the changes.

The VIT program module is now configured.
