To set up the AUTO-Uragan program module, do the following:

  1. Go to the settings panel of the AUTO-Uragan module object, 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 that characterizes the motion detector sensitivity to the contrast of the video image. When recognizing, the AUTO-Uragan module also determines the vehicle dimensions. The lower the value, the higher the detector sensitivity. The value of the Sensitivity of vehicle detection parameter 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 the displayed frame. This setting is relevant only for the cars whose license plates aren't recognized. If the license plate isn't recognized, the module gives as a result the frame located at the specified distance from the frame with the first car appearance.

    Note

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

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

  6. In the Minimum validity of LP recognition (recommended range 60-100%) field (5), enter the value of minimal validity of recognition in percent. The validity of recognition is determined by the degree of similarity between the recognition result and the LP template and allows distinguishing the LP from other marks on the vehicle.

    Note

    During license plate recognition, the validity is displayed in the list of parameters in the Active monitor window.

  7. Set the Obscured LPs checkbox (6) to increase the quality of recognizing vehicles with obscured license plates.
  8. Set the Skip unrecognized LPs checkbox (7) to ignore unrecognized license plates.
  9. The Number of lanes in camera field of view non-editable field (8), displays the number of lanes determined by the AUTO-Uragan module.
  10. Set the Allow checkbox (9) to enable the ability to recognize the two-line LPs.
  11. Set the maximum width and height of the area within which the license plate is searched (set in percent of the full frame) (10). Click the Х button to set these parameters. In the Two-line LPs window that opens, click the Stop video button when the appropriate frame appears and select the area of the required size.

    After you click the OK button, the specified area parameters are automatically entered in the Maximum width and Maximum height fields.
  12. Set the minimum area width and height within which the license plate is searched (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 drop-down list (12), select the SDK version of the AUTO-Uragan program module. We recommend using the 3.8 (default) version. 

    Note

    For the proper operation of Auto PSIM on the computer with OS Windows 7 and lower, the 3.7 SDK version is required.

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

    After you change the SDK version, you must restart Auto PSIM to apply the changes.

  14. Set the Parallel checkbox (13) if you want to recognize a license plate simultaneously on several processors using parallel computing, which improves the performance of the AUTO-Uragan program module.

  15. In the Number of CPUs field (14), specify the number of processors that are 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 are involved in the license plate recognition.

  16. The typical minimum size and the typical maximum size of license plates recognized by the Auto-Uragan module are displayed in the Typical minimum size and Typical maximum size non-editable fields, respectively (15).

    Note

    If no LPs are recognized, the Typical minimum size and Typical maximum size fields aren't displayed.

    The Typical minimum size and Typical maximum size fields are displayed only with the enabled debug mode (Debug 1-Debug 4). 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 are applied to all activated AUTO-Uragan program modules in Auto PSIM.

Setting up the AUTO-Uragan program module is complete.
