To optimize the operation of the License plate recognition VT on GPU, do the following:

  1. Stop the server (see Stopping Stop the server).
    Note
    titleAttention!

    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:\IX_GPU_cache. The specified directory will store the cache for all used detectors and neural networks.

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

  4. Enter the required countries in countries in the numeric or alphabetic form.
