AutoTRASSIR/AutoPass general settings

Important

Before the AutoTRASSIR configuration, we strongly recommend you to read the section AutoTRASSIR/AutoPass.

For the license plate recognition system to operate correctly, the camera must include certain features and be installed and set in a proper way. Please familiarize yourself with Selecting, installing, and configuring cameras to work with the AutoTRASSIR/AutoPass plugin.

Before using the AutoTRASSIR plugin, be sure you have correctly configured your database connection.

Main parameters of the AutoTRASSIR/AutoPass plugin are displayed on the Plugins -> AutoTRASSIR/AutoPass tab of the Settings window.

  • Only for the AutoTRASSIR plugin:

    In the LPR core configuration, select the version of AutoTRASSIR.

    Tip

    After changing the version of the plugin, the server must be rebooted.

  • Only for the AutoTRASSIR plugin:

    In the Country preset you can select the country in which license plate recognition will take place. Furthermore, the templates of the selected country and of the neighboring ones will be displayed in Visualization templates list. You can also select custom item and enable the required templates manually.

    The recognition template for the HSC AutoPass plugin is chosen during its setting (see Setup HSC AutoPass plugin on a channel).

    Tip

    AutoTRASSIR/AutoPass recognizes license plates regardless of the selected country visualization template. The display of the visualization templates is required only in the operator's interface. Thus, if the recognized license plate corresponds to the selected country template, it will be displayed in that country format in the operator's interface.

    or

    Otherwise, the recognized license plate will be displayed as a set of recognized characters.

    Tip

    Select Chinese in OCR type setting in order to increase the quality of Chinese license plate recognition in AutoTRASSIR (LPR3). Use standard OCR type in any other cases.

  • Only for the AutoTRASSIR plugin:

    The Licenses usage field shows the number of currently connected channels out of the maximum allowed (which is limited by your license).

  • Only for the AutoTRASSIR plugin:

    The Channels section displays the list of channels for which AutoTRASSIR has been activated.

  • For AutoTRASSIR and HSC AutoPass plugins:

    The Mismatch with list record setting lets you set up mismatch which can be used for the recognized numbers search in the internal lists, from 0 to 5 symbols.

    Tip

    E.g. the Mismatch with list record threshold value is set to 1 and the license plate number 6063361 is in the whitelist.

    In case AutoTRASSIR makes a mistake in 1 symbol when recognizing a license plate and recognizes 4063361 or 606336 instead of 6063361 number, due to 1 symbol mismatch, the mistakenly recognized number will match with the number from the whitelist.

  • For AutoTRASSIR and HSC AutoPass plugins:

    The External lists area displays a list of all of the external lists connected to AutoTRASSIR.
