Background
The Operations Commander system has the ability for the system to map plates to new values. In layman's terms this means that this process of filtration can take an image of a plate and find many possibilities of what the plate may be matched to based on commonly misconstrued characters and the license plates registered or in the known area database. An example of this may be a plate that is read by LPR may be read as ABC128 when the plate is actually ABC123.
The user is able to make this update and store the details. This can be problematic for the user if the plate is never seen again and 8's are regularly interpreted as 3's
Update
This issue in the functionality of the LPR software is addressed by the use of the above methods and the use of the lookup table implemented to match which characters are easily misconstrued. The lookup table that follows is comprised of data from past LPR updates by users;
| Characters | Similar Characters | Characters | Similar Characters |
| 1 | "1I" | K | "HKR" |
| 2 | "2Z" | M | "HKM" |
| 3 | "38B" | O | "0DOQ" |
| 5 | "5S" | P | "FP" |
| 8 | "38B" | Q | "0DOQ" |
| B | "38B" | R | "HKR" |
| D | "0DOQ" | T | "TY" |
| E | "EF" | V | "VY" |
| F | "EFP" | Y | "VTY" |
| H | "HKMR" | Z | "2Z" |
| I | "1I" |
