  1. Go to the VIT module object settings panel, which is created on the basis of the LPR Channel object.
  2. Set the Zooming checkbox checked to increase the plate recognizing speed on mega-pixel video cameras without loss of recognizing quality (1).

    Info
    titleNote

    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.


  3. To prevent the loss of processed frames, it is recommended that each megapixel of the video camera be processed in a separate stream. If there is a loss of frames, then it is necessary to increase the number of streams in the Number of streams for frame processing field (2):
    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 or more, recognition will be performed in two or more streams simultaneously to the process that starts it. However, in this case, 1 license channel is used for each stream.

5. Perform fine tuning of SDK if required (3, see VIT module object settings panel).

Note
titleImportant!

Fine tuning of SDK is to be performed only with the help of AxxonSoft specialists!
