Once more, Quercus Technologies proves its high success rate in license plate recognition, achieving 99.7% reliability with UK license plates

Quercus Technologies is continuously improving the recognition of license plates in the regions and countries where it recognizes plates and aims to increase the list further, in response to new customer demands as well. The SmartLPR Access license plate recognition cameras, which control access to numerous car parks around the world, have once again proven their high reliability after analyzing a sample of over 3,000 UK license plates, with a 99.7% success rate. 

This rate has been calculated by discarding only those recognitions that have resulted in an error regarding a single character due to the placement of dark-colored fixing screws on the UK plates, 1% of the total. This indicates that in the case of wanting to use an n-1 comparison for automatic access, the operation would be optimal and the probabilities of being right are infinitely higher than the probabilities of an unauthorized vehicle accessing the facilities.

It is well known that the placement of the fixing screws in the UK causes alterations to the ANPR parking systems, as explained in more detail in the University of Hertfordshire article. As you can see in the image, part of the sample analyzed by our team is the case in which an "S" is interpreted as a "G" due to the location of the fixing screw.

Throughout the year, Quercus Technologies' Research and Development and Customer Service departments, always prioritizing our customers' needs and interests, continue to improve the recognition rates of our products in all regions and continue creating new recognized countries. Some of the highlights of this year are the improvements in the license plates corresponding to Belgium, Germany, Australia, Russia, Mexico and some states of the United States, such as Arizona or Colorado, and the integration of new license plate models into our reading engine from countries like Iceland, Sri Lanka, Nebraska or Mexico City, among many other regions of the world.

At Quercus Technologies we understand that evidence is more important than words, and that is why we constantly provide data which is relevant to our customers and our industry. We provide the customer with performance analysis of their facilities, among other services offered.
