Setting up license plate recognition upon request

The Licence Plate Recognition channel enables license plate recognition upon request. This is enabled by the dedicated functionality included in the Licence Plate Recognition channel that enables configuring cameras that capture images and pass them to the recognition module after a specific trigger activates. It can be, for example, a macro, a script, or some event. This functionality is implemented on the basis of a separate object in Auto-Intellect.

In order to configure the recognition upon request, create the Camera of recognition upon request child object on the basis of the LPR channel parent object.

On the settings panel of the Camera of recognition upon request object, in the Camera drop-down list, select the camera that will work on request from the list of cameras displayed in the Video capture device tree.

The request, which will trigger the camera, can be configured in two ways:

1. Using a macro. To do this, switch to the Programming tab in Intellect and select the Macros item in the programming tools tree. A window for creating a macro will open, enabling you to create an event of any complexity that will trigger the recognition upon request. An example of the simplest macro for recognition upon request is shown in the figure below. For details on working with macros, see Creating macros.
   

2. Using a script or the IIDK interface. To do this, switch to the Programming tab in Intellect and select the Scripts item in the programming tools tree. A window for creating a script will open, enabling you to create an event of any complexity that will trigger the recognition upon request.  For details on working with scrfipts, see Creating a script. An example of a simple script for working with a camera for recognition upon request is shown below.

   QUERY_CAMERA|ID|RECOGNIZE

   where ID is ID of the camera in the Intellect object tree. 

   For details on the IIDK interface, see Intellect Integration Developer Kit (IIDK).

   At the moment of this writing, the functionality described in this section works only with the CARMEN and VIT recognition modules.
