Note

If you create several RR recognition channels, the load on the CPU cores can be uneven, because the even distribution mode isn't enabled by default. The enable it, set the 1 value for the string parameter of the IsProcessObject registry key (see Vertical solutions). In this case, each recognition channel is started in a separate process.

To configure the RR vendor and model recognizer module, do the following:

  1. Go to the settings panel of the RR vendor and model recognizer object that is created on the basis of the LPR channel object.

  2. From the drop-down list, select the type of neural network for recognizing vendors and models of RR vehicles:

    1. Lightweight for CIS countries (default);

    2. Medium-weight for CIS countries;

    3. Lightweight for other countries;

    4. Medium-weight for other countries.

  3. In the Number of streams field, specify the number of streams that the SDK of the RR recognizer uses during parallel computing. The 0 value (default) disables parallelization during license plate recognition.

    Attention!

    Increasing the number of streams during parallel computing also increases the load on the CPU. All changes are applied only after you restart Axxon PSIM.

  4. Click the Apply button to save the settings.

    Attention!

    To increase the performance of license plate recognition, you can use computing resources of the graphics card. To do this, when configuring the LPR channel object (see Selecting a device for license plate recognition), from the Use GPU drop-down list, select the required device. By default, only CPU computing resources are used.

    The start (initialization) time of the license plate recognition algorithm using a graphics card can take several minutes. No license plate recognition events are received until the initialization is complete.

    GPU files are included in the distribution package starting with Auto PSIM version 1.0.1.293. No additional installation is required.

    For Auto PSIM earlier than version 1.0.1.293, you must activate computing resources of a graphics card:

    1. Download the distribution package to activate the GPU for the RR module from the AxxonSoft website.
    2. Unzip the downloaded archive.
    3. Put all files of the downloaded archive into the folder on the computer with installed Auto PSIM at C:\Program Files (x86)\Axxon PSIM\Modules64\UrmLpr\RR_gpu.

Configuration of the RR vendor and model recognizer module is complete.
