Starting from DetectorPack 3.10, a utility was added to the RR LPR add-ons (see Installing DetectorPack add-ons), which allows you to create GPU network caches without using C-Werk. The presence of the cache speeds up the initialization and optimizes video memory consumption.

To optimize the operation of the License plate recognition (RR) and RR vehicles on GPU, do the following:

  1. Stop the Server (see Shutting down a Server).

    Attention!

    If the system has the software running on GPU, it is necessary to stop its operation.

  2. Create the GPU_CACHE_DIR system variable (see Appendix 9. Creating system variable) by specifying in the Variable value field the path to the cache location with an arbitrary folder name. For example, D:\GPU_cache. The specified directory will store the cache for all used detection tools and neural networks.

  3. To call the utility, open in the command line: C:\Program Files\Common Files\Grundig\DetectorPack\RoadarGpuCacheGenerator.exe and press Enter.

  4. Select the required cache sets by specifying the y value:

    1. lpr recognition—recognition of a vehicle license plate;
    2. vehicle recognition—recognition of a vehicle.

      When you select the lpr recognition cache set, you need to specify the required countries in the numeric or alphabetic form. After you select all required countries, enter the -1 value.

    3. When you select the vehicle recognition cache set without lpr recognition,

      you must choose the territory where vehicle recognition is going to be performed:

      1. CIS countries (1);
      2. Other countries (2).
  5. Select one of the accuracy and performance values by specifying the corresponding number:

    1. Medium accuracy, high performance of the GPU (1)—provides medium recognition accuracy, less load on the GPU;
    2. High accuracy, medium performance of the GPU (2)—provides high recognition accuracy, but creates a higher load on the GPU.
  6. Specify the ID of the required GPU (see General information on configuring detection) and press Enter.

    As a result, the process of creating a cache will start, which will take about 30 minutes. The duration of the process depends on the selected types of cache, number of countries and NVIDIA GPU model.

Optimizing the operation of the License plate recognition (RR) and RR vehicles on GPU is complete. 

Attention!

If you update the RR LPR add-ons (see Installing DetectorPack add-ons) or change the NVIDIA GPU model, the cache must be recreated.
