| 1 | The Symbol height group |
Minimum |
field
| Enter the value in the text field | Sets the minimum height of the carriage number symbol in |
pixelsthe video image from the camera
| Pixels | 28
| >=0 |
| Average |
field | Enter the value in the text field | Sets the average height of the carriage number symbol in |
pixels| the video image from the camera | Pixels | 32 | >=0 |
| Maximum |
field | Enter the value in the text field | Sets the maximum height of the carriage number symbol in |
pixels| the video image from the camera | Pixels | 40 | >=0 |
| 2 | The Symbol inclination |
group field | Enter the value in the text field | Sets the average |
slope inclination 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
| Percent | -2
| <>=0 |
| Minimum (%) |
field | Enter the value in the text field |
Sets the slope inclination 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
| Percent | -30
| <>=0
|
| Maximum (%) |
field | Enter the value in the text field | Sets the maximum |
slope inclination 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
| Percent | 21
| <>=0 |
| 3 | The Advanced settings group |
Slope (%) |
field
| Enter the value in the text field |
Sets the | Sets the slope of the carriage 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 | Percent | 1 | <>=0 |
Min. contrast |
field
| Enter the value in the text field | Sets the estimated difference between the shades of gray of the LP symbols and the background | Shades of gray
| 15 | >=0 |
X in Y (%) |
field
| Enter the value in the text field | Sets the |
rate | ratio of the horizontal and vertical 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 | enter zero or a negative value, then the value will automatically changed to 100 | Percent | 100 | >=0
|
| Delay |
field| | Enter the value in the text field | Sets 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 | Milliseconds | 1000 | >=0 |
| 4 | The Filters group |
| ISO filter |
checkbox | Set the checkbox | Enables 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) | - |
YesYes − Set—the filtering is enabled |
No − the Clear—the filtering is disabled |
| Long code filter |
checkbox| | Set the checkbox | Enables the long numbers filtering. If the video image does not contain |
the carriage | the carriage number, but contains some other text, the recognition module can display a |
false carriage | false carriage number. The long numbers filtering reduces the likelihood of the false |
numbers | codes appearing, increases the runtime (by about 5%), and degrades the recognition of |
the carriage | the carriage codes on the images with |
a carriage | a carriage code (by about 0.5%) | - |
YesYes − Set—the filtering is enabled |
No − Clear—the filtering is disabled |
| Checksum test |
checkbox | Set the checkbox | Enables the testing of the checksum of the numbers | - |
NoYes − Set—the testing is enabled |
No − Clear—the testing is disabled |
