Attention!

To ensure the correct operation of the CARMEN-Carriages software module, it is necessary to additionally install the software from the manufacturer’s website.

The CARMEN-Carriages software module is configured as follows:

  1. Go to the CARMEN-Carriages module object settings panel, which is created on the basis of the LPR channel object.
  2. In the Symbol height group, specify the height parameters for carriage license plate number symbols on the video image from the camera:
    1. In the Average field (1), enter the average height of the symbol in pixels.
    2. In the Minimum field (2), enter the minimum height of the symbol in pixels.
    3. In the Maximum field (3), enter the maximum height of the symbol in pixels.
  3. In the Slope (%) field (4), 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.
  4. In the Min. contrast field (5) enter the estimated difference between the shades of gray of the LP symbols and the background.
  5. In the X in Y (%) field (6), 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.

  6. In the Delay field (7), 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.

    Note

    Increasing the delay time can be useful if the same carriage number is displayed too often.

  7. 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.
  8. In the Recognition frame rate field (9), enter the number of frames per second that will be processed by the recognizer.
  9. 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.
  10. 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.
  11. Select the ISO filter checkbox (18) 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).
  12. Select the Long code filter checkbox (19) 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%).
  13. 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.
  14. Click the Apply button (21) to apply the settings.

Configuring the CARMEN-Carriages software module is complete.
