Configuring the IntelliVision RIDR module

Configure the IntelliVision RIDR module as follows:

1. Go to the settings of the IntelliVision RIDR module object created under the LPR channel object.
   
   

2. Set the Use GPU (1) checkbox 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.

3. Select the numbers recognition accuracy in the Accuracy (2) drop-down list. The following options are available:
   
   1. Maximum - enables maximum recognition accuracy, but it causes great CPU and/or GPU load.  
   2. High - enables high recognition accuracy, it requires less computing resources than for maximum accuracy.
   3. Fast - enables high recognition speed, but the accuracy becomes worse.
4. Select the computing resources use mode in the Strategy (3) drop-down list. The following options are available:
   1. Process  - mild mode: no more than 1 core for 1 license plate.
   2. System - default mode: all available computing cores are in use;
   3. Core  - strict mode: 1 core per stream.
5. Specify the minimum time interval lasting between the frames processing for the Interval (4) parameter (i.e. all frames within this interval won't be processed).

6. Select the profile of country license plates that are to be recognized in the Profile (5) drop-down list. Greater profile number enables more accurate LPR comparing to the solution with smaller number, but it is more demanding to computing resources. The following options are available: 6 and 9.

7. Click Apply (6).

Configuration of the IntelliVision RIDR module is completed.
