To configure the RoadAR software module, do the following:

  1. Depending on the license type, go to the settings panel of the RoadAR module (fast) or RoadAR module (slow) object, which is created on the basis of the LPR channel object.
  2. In the Number of streams field (1), enter the number of streams that the RoadAR SDK will use in parallel computations. A value of 0 disables the calculating process paralleling for the license plate recognition.

  3. In the Maximum track size (frames) field (2), enter the maximum number of frames for one track that will be processed by the RoadAR SDK (the smaller the value, the faster the recognition result will be given, but it will also be less accurate). The default value is 0. The number of frames is not limited.

    Attention!

    If the LP recognition upon request is used (see Setting up the Camera of recognition upon request module), the Maximum track size (frames) should be equal to 1.

  4. Set the Skip unrecognized LPs checkbox (3) to ignore the vehicles with unrecognized license plates.

  5. Set the Use GPU checkbox (4) if it is necessary to use the NVIDIA GPU resources to increase the license plate recognition performance. By default, only the CPU resources are used.

    Attention!

    The startup (initialization) of the license plate recognition algorithm on NVIDIA GPU can take about one minute. No LP recognition events will be received until the initialization is complete.

  6. By default, only numbers of the main country are recognized, which is specified in the settings panel of the LPR channel object (see Selecting the country and license plate recognition SDK). If it is also necessary to recognize the numbers of additional countries, click the Select country button (5) and in the Country selection window that opens, select the required countries.
  7. If it is necessary to determine the speed by video, specify the appropriate camera settings (6). The specified parameters should correspond to the actually used camera and its mounting parameters.
  8. To save the settings, click the Apply button (7).

The configuration of the RoadAR software module is complete.

Note

If several Roadar 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).
