Setting up the AUTO-Uragan program module is done in the following way:

  1. Go to the AUTO-Uragan module object settings panel, which is created on the basis of the LPR channel object.
  2. In the Sensitivity of vehicle detection (1-255) field (1), enter the sensitivity value which characterizes the motion detector sensitivity to the contrast of video image. When recognizing, the AUTO-Uragan module also determines the vehicle dimensions. The lower the value, the higher the detector sensitivity. The Sensitivity of vehicle detection parameter value is selected by testing the detector for false positives.

  3. In the Car position in frame, % field (2), enter the value in percent, showing the position of a car in a displayed frame. This setting is relevant only for those cars which plates have not been recognized. If the plate has not been recognized, the module gives as a result the frame located at the specified distance from the frame with first car appearance.

    Note

    The moment when the car appears in the frame is considered as 0%. The moment when the car leaves the frame is considered as 100%.

  4. Set the Full interval between cars checkbox (3) if you want the recognizer is to be in a waiting state with motion absence in the whole frame. This adjustment can improve the quality of recognizing long vehicles (e.g. trucks) in the frame.
  5. Set the Recognize license plates only in areas where motion is detected checkbox (4) to increase the recognizing speed on mega-pixels video cameras.

  6. Enter the value of minimal validity of recognition in percent in the Minimum validity of LP recognition (recommended range 60-100%) field (5). Validity is defined by the degree of similarity between results of recognition and the LP template and it allows distinguishing the LP from other marks on the vehicle.

    Note

    The validity is displayed in the List of parameters of the Active monitor dialog box.

  7. Set the Obscured LPs checkbox (6) to increase the quality of recognizing the vehicles with obscured plates.
  8. Set the Skip unrecognized LPs checkbox (7) if it is necessary to ignore unrecognized numbers.
  9. The non-editable Number of lanes in camera field of view field (8) displays the number of lanes captured by the AUTO-Uragan module.
  10. Set the Allow checkbox (9) to enable the possibility of recognizing the two-line LPs.
  11. Set the maximum width and height of area where the search of LPs is performed (set in percent of the full frame) (10). Click the  button to set these parameters. In the Two-line LPs opened dialog box, click the Stop video button when the appropriate frame appears and select the area of the required size.

    Click the OK button and the specified area parameters will be automatically entered in the Maximum width and Maximum height fields.
  12. Set the minimum area width and height where the search of LP is performed in the Minimum width and Minimum height fields (11) (set in percent of the full frame) by analogy with the Maximum width and Maximum height parameters—see step 11.

  13. In the Current version field (12), select the SDK version of the AUTO-Uragan module. SDK version 3.8 (default) is recommended. 

    Note

    You can also change the SDK version using the batch files (see Changing the SDK version using batch files).

    Attention!

    After changing the SDK version, it is necessary to restart Auto PSIM to apply the changes.

  14. Set the Parallel checkbox (13) if it is necessary to recognize a LP number simultaneously on several processors using parallel computing, which improves the performance of the AUTO-Uragan module.

  15. In the Number of CPUs field (14), specify the number of processors which will be used for the parallel computing, if the Parallel checkbox is set.

    Note

    Processors are physical and logical cores available on the Server. For example, if there are 8 cores available on the Server, and the Number of CPUs field value is set to 4, then only the cores from 1 to 4 will be involved in the LP numbers recognition.

  16. The typical minimum size and the typical maximum size of plates recognized by Auto-Uragan program module will be correspondingly displayed in the Typical minimum size and Typical maximum size non-edited fields (15).

    Note

    • If no LPs were recognized, the Typical minimum size and Typical maximum size fields won't be displayed.
    • The Typical minimum size and Typical maximum size fields are displayed only if the Debug 1-Debug 4 mode is enabled. The debug mode is described in Axxon PSIM software package. Administrator's Guide.

  17. Click the Apply button to save the changes.

    Note

    The Current version, Parallel, and Number of CPUs parameters will be applied to all activated AUTO-Uragan software modules in Auto PSIM.

Setting up the AUTO-Uragan program module is completed.
