Settings of LP processing include the following functionality:

1. Automatic transcoding of Latin characters into Cyrillic, if the license plate recognition module returns recognized numbers in Latin characters (for example, LPR IntelliVision, RoadAR).
2. Ignoring numbers that are contained in the predefined list of rules. Rules can contain either an exact number or a regular expression. This allows, for example, to ignore the LP numbers of a certain region.
3. Ignoring repeated license plate recognition.

LP processing is configured in the following way:

1. On the LPR channel object settings panel, go to the Settings of LP processing tab (1).
   
   
2. To enable automatic transcoding of Latin characters into Cyrillic, set the Character transcoding (Latin->Cyrillic) checkbox (2).

3. If it is necessary to ignore repeated license plate recognition, in the Skip repeated recognitions, s field, enter the time period in seconds greater than 0, during which the captured license plate should not be recognized again (3).

   The value of the Skip repeated recognitions, s field has a limit of 86400 seconds (number of seconds in a day).

   
   

4. To configure the ignoring of numbers according to the list of rules, do the following:

   1. Right-click on the Skipped LPs field, and then click the Add button (4).

      

   2. Enter the required rule using regular expressions (5). A rule can contain either an exact number or a regular expression.
      
      
      

      For example, the regular expression ".555.+" means that there can be only one arbitrary character before "555", and many arbitrary characters after "555".

      
      

   3. Click OK (6).

   4. To edit or delete an already added rule, right-click on it and select the appropriate action by clicking Edit (7) or Delete (8). The Delete all button (9) is used to delete all rules.
      

   5. You can check if the specified rule is correct. To do this, enter the test LP in the Enter LP field (10) and click Check (11). The result will appear below in the field (12).

      The maximum number of characters in the Enter LP field is 30.

      

5. Click Apply (13). 

The LP processing is now set up.
