If several RR recognition channels are created, the load on the CPU cores may 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).

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. Set the Use GPU checkbox if you want to use computing resources of the graphics card selected when configuring the LPR channel object (see Selecting a device for license plate recognition) to increase the performance of license plate recognition. By default, only CPU computing resources are used.

    The start (initialization) time of the license plate recognition algorithm using a graphics card may take several minutes. No license plate recognition events will be received until the initialization is completed.

    To activate the computing resources of a graphics card, do the following:

    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\Roadar_gpu.

  3. 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.

  4. Click the Apply button to save the settings.
