Starting with with DetectorPack 3 3.10, a utility was added to the VT LPR add-on on (see   Installing DetectorPack add-ons), which allows you to create GPU neural network caches without using using Axxon One. The presence of the cache speeds up the initialization and optimizes video memory consumption.

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

1. Stop the
Server
2. server (see
 Shutting down a Server
3. Stopping the server).
   

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

4. Create

the 

5. the GPU_CACHE_DIR

 system

6.  system variable (

see 

7. see Appendix 9. Creating system variable) by specifying in

the 

8. the Variable value

 field

9.  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

detection tools

10. detectors and neural networks.

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

 and press 

12.  and press Enter.

13. Enter the required countries
 
14. in the numeric or alphabetic form.

15. After you
selected
16. select all required countries,
enter
17. enter done.
18. The default
resolution
19. frame width is
1920x1080
20. 1920 pixels. If
you want to change the resolution
21. necessary, enter
y
22.  y value and the required
resolution
23. frame width. For example,
 
24. 2048.
25. To leave the default value,
enter
26. enter n.
    
27. Specify the minimum width of the license plate according to the actual size of the license plate in the frame as a percentage. The minimum allowed value is 0, the maximum value is 100.
    
28. Specify
the 
29. the ID
 of
30.  of the required GPU (see
 
31. Selecting Nvidia GPU when configuring
detection tools
32. detectors).
33. Press Enter.

As a result, the process of creating cache starts, which takes 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 VT on plate recognition VT on GPU is complete.
