Configure the ARH-Railway module as follows: 

1. Go to the Go to the Main settings tab (1) of the ARH-Railway module object settings panel.
   Image Added
2. From the SDK work sequence drop-down list (2) select Sequentail or Parallel. 
3. In the Quality field (3), enter the image quality of the carriage or container numbers, starting from which the numbers will be recognized. The value is determined experimentally.
4. In the Recognition frame rate, fps field (4), enter the number of frames per second processed by the recognizer. If you enter 0 or leave the field empty, the recognizer will process the maximum possible number of frames.
5. Go to thetab of SDK is created on the basis of the LPR channel object.

6. In the Symbol height group, specify the height parameters for carriage or containerlicense plate number symbols on the video image from the camera:
   1. In the Average Minimum field (12), enter the average minimum height of the symbol in pixels.
   2. In the Minimum Average field (21), enter the minimum average height of the symbol in pixels.
   3. In the Maximum field (3), enter the maximum height of the symbol in pixels.
7. In the Symbol inclination group, specify the slope parameters of the carriage number symbols on the video image from the camera:
   1. In the Average (%) field (4), enter the average slope of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
   2. In the Minimum (%) field (5), enter the minimum slope of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
   3. In the Maximum (%) field (6), enter the maximum slope of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
8. In the Advanced settings group, specify:
   1. In the Slope (%) field (
   4
   1. 7), enter the slope of the carriage LP number in relation to the video image received from the camera in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
   2. In the Min. contrast field (
   5
   1. 8) enter the estimated difference between the shades of gray of the LP symbols and the background.
   2. In the X in Y (%) field (
   6
   1. 9), enter the rate of the horizontal symbol resolution to the vertical one in percent. The horizontal resolution is the ratio of the symbol width on the video image to its actual width, and the vertical resolution is the ratio of the symbol height on the video image to its real height. If you put Zero or negative value, then the value will automatically changed to 100.

   2. In the Delay field (

   7

   1. 10), enter the time interval in milliseconds that should expire in order for the recognition module to display the next number recognition result. A value of zero means no delay.

      Info
      title Note
      Increasing the delay time can be useful if the same carriage number is displayed too often. If the LP recognition upon request is used (see Setting up the Camera of recognition upon request module), there should be no delay.

      
      

9. In the Quality field (8), enter the image quality of the carriage numbers, starting from which the numbers will be recognized. The value is determined experimentally.
10. In the Recognition frame rate, fps field (9), enter the number of frames per second processed by the recognizer. If you enter 0 or leave the field empty, the recognizer will process the maximum possible number of frames.
11. In the Symbol inclination group, specify the slope parameters of the carriage number symbols on the video image from the camera:
    1. In the Average (%) field (10), enter the average slope of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
    2. In the Minimum (%) field (11), enter the minimum slope of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
    3. In the Maximum (%) field (12), enter the maximum slope of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
12. In the Checksum test group, make the following settings:
    1. Select the 6 symbols check box (13) if it is necessary to check the checksum of the numbers that consist of 6 symbols.
    2. Select the 8 MOCO symbols and 4 signs check box (14) to check the checksum of the numbers that consist of 8 symbols.
    3. Select the 10 signs check box (15) if it is necessary to check the checksum of the numbers that consist of 10 symbols.
    4. Select the 11 signs check box (16) if it is necessary to check the checksum of the numbers that consist of 11 symbols.
    5. Select the Russian wagon number check box (17) if it is necessary to check the checksum of the Russian carriage numbers.
13. Filters group, specify:
    1. Select the ISO filter checkbox (11
    Select the ISO filter checkbox (18
    1. ) if it is necessary to enable the ISO carriage numbers filtering. When reading a number that consists of 11 symbols, the recognition module will attempt to read the ISO code (examples of ISO codes: GB4310, 22G1).
    2. Select the Long code filter checkbox (
    19
    1. 12) if it is necessary to enable the long numbers filtering. If the video image does not contain the carriage number, but contains some other text, the recognition module can display a false carriage number. The long numbers filtering reduces the likelihood of the false numbers appearing, increases the runtime (by about 5%), and degrades the recognition of the carriage codes on the images with a carriage code (by about 0.5%).
14. Set the UIC filter wagon number checkbox (20) if it is necessary to enable the filtering of UIC carriage numbers. If the check number in the carriage number does not match the expected check number according to the UIC standard, then this number will be ignored.
15. 1. Select the Checksum test checkbox (13) if it is necessary to check the checksum.
    1. e of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
    2. In the Maximum (%) field (12), enter the maximum slope of the symbol in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up.
16. Click the Apply button to Click the Apply button (21) to apply the settings.
