Select the country and license plate recognition SDK

General information

When you configure the LPR channel with the activated AUTO-Uragan/VT/RR/IV module, you must specify the country whose license plates must be recognized.

When you configure the LPR channel with the activated AR-Auto/AR-Railway module, you must specify the license plate recognition SDK.

Select the country for license plate recognition

To select the country, do the following:

1. Go to the settings panel of the LPR channel object, representing the activated recognition module.
   

2. From the Country drop-down list, select the country for license plate recognition.

   Attention!

   The By default value is available for the IV module. In this case it is possible to recognize license plates of all supported countries, though the recognition quality can decrease.

   There is a special utility for the VT and AUTO-Uragan modules (see PatCgfr.exe utility for active patterns configuration or PresetEditor.exe utility for active patterns configuration of VT module) using which you can set template configurations. Each configuration determines what license patterns will be recognized by the camera. Using various configurations, you can set various recognition rules for various cameras.

   If the software module supports the two-line license plate recognition, then in order to display them in the Event viewer in two lines, it is necessary to set the RemoveNewLine registry key value to 0 (for details, see Registry keys reference guide, for more information about working with the registry, see Working with Windows OS registry).

Select the license plate recognition SDK

To select the license plate recognition SDK, do the following:

1. Go to the settings panel of the LPR channel object, representing the activated recognition module.
   

2. From the Module drop-down list, select the SDK for license plate recognition.

   Note

   To add the SDK for license plate recognition, you must download the required SDK from the AxxonSoft website and install it using the EngineManager utility. The procedure of installing the recognition engines using the EngineManager utility is described in the engine_install_windows.txt file located in the folder with the corresponding recognition engine.

   If the AR-Auto module is activated, then the cmanpr-7.2.7.108: general SDK is used by default for recognizing all Latin characters of the license plates (for example, corresponding to countries such as Argentina, India, Africa, and Singapore), although the country recognition function is not used.

   The Hazard Identification Number Recognition Engine (ADR) SDK can be added to the list of the countries as a separate "country". This SDK is named cmanpr- <version number>: latin_eadr in the list of countries. If you select it as the country issuing the license plate, the recognition module can identify the license plates of the states using the Latin alphabet, as well as the specialized license plates of vehicles carrying hazardous goods, with detection and recognition of the type of cargo being transported. The information about the transported cargo will be displayed by the Vehicle Tracer module in the list of vehicle parameters and also sent in the event about the recognized number.

   Two-line license plates are supported in the AR-Auto module when the cmanpr-<version number> : arab recognizer is selected.

   In the online monitor, the recognized Arabic license plates are always displayed in two lines. The first line begins with the Arabic numbers, and then the Arabic letters are displayed. The second line, by default, begins with the Latin letters, then numbers. To display in the second line the Latin numbers first and then the letters, it is necessary to set the value of the string parameter of the VehiclePlateSearch.RightToLeft registry key to 0 (for details, see Registry keys reference guide, for more information about working with the registry, see Working with Windows OS registry).
