You may have seen a stacked character plate, or perhaps you even have one on your vehicle.
When it comes to license plates, the USA is incredibly diverse. Each US state has its unique license plate with distinct design features, fonts styles, colors, templates, and more. Often times state flags, slogans, names, or images will be embedded into the license plate, or having “stacked characters” added to the rest of the plate information. TagMaster NA’s innovative CT-45 LPR camera is able to accurately read stacked characters on license plates throughout the USA.
One of the key advantages of working with TagMaster NA LPR is that we view the OCR engine and library as dynamic. We keep up to date on new plate issuances, new fonts, syntaxes, colors, sizes, stacked characters, etc. and ensure they are added and updated into our OCR library to ensure the best performance possible. We can also provide changes and updates for new plates/issuances/difficult-to-read plates in your region. Read our recent Press Release: Lake Lanier LPR, here we were able to update the LPR camera OCR with new state issued license plates ensuring accuracy above 98% for this location.
Most of our license plates regularly issued for non-commercial passenger vehicles usually have 5-7 characters while vanity plates or specialty plates can have up to 8 characters.
Stacked characters can sometimes be issued to represent things like: wildlife preservation, military service, and etc.
Some license plates have some of its characters placed on each other vertically while the remaining characters are arranged horizontally. These stacked characters can be on the left side or the right side of the plate, but are generally found stacked on the left hand side of the license plate.
Although the stacked characters are notoriously difficult for LPR to recognize and read, TagMaster LPR takes it to another level. Our highly intelligent onboard processing and OCR engine has the capability to not only recognize stacked character plates, but with a simple toggle button on the convenient web-based UI you can choose to read these stacked characters, or you can select to ignore them. This gives you the ultimate flexibility and accuracy advantage possible.
Our goal at TMNA R&D is for our LPR solutions is to make the user’s life as easy as possible by ensuring the highest accuracy, best capture rates and fastest processing with our state of the art LPR camera solution; CT-45.
How are we able to read these difficult license plates without issue?
It all starts with our OCR engineering team putting their PhDs to work. Having a highly adjustable and easy to tune engine with an easy to use web based user interface allows us to offer the market an accuracy and performance level unmatched.
