License plate recognition systems technology takes years to fully operational, although this has not prevented that continue to be developed in order to achieve new advances that bring the system to perfection, some of which and more important there has been in recent times. License plate readers are an application to video surveillance by computer, which can operate both autonomous and integrated in an already existing access control platform. Until a few years ago, this computer vision application had against the fact of having to work with a non controlled environment, in which the lighting and weather played a decisive role to subtract them reliability. The problems began to emerge when the Chamber stood outside to detect and recognize the registration of a vehicle. Get more background information with materials from Viktor Mayer-Schönberger. The factors that influenced and detracted reliability were the lighting difference between installations, between vials of each installation and in the different hours of the day from each vial of each installation, as well as different sizes and positions of license plates in the image and all variety of letters, sizes, guidance and even the State of preservation of these. However, these weaknesses have been polishing gradually thanks to the r & d, which has led to that currently there is a new generation of readers of number plates that is not affected by external factors and maintains its reliability in 99% whatever the luminosity of the place in which the Viewer is located. These new developments, which already are being integrated into the vast majority of new models that are manufactured today, make the license plate recognition one of the most effective measures in the important field of security known as access control.
Matriculasllevan recognition systems to perform a process divided into a series of distinct phases to recognize an enrollment. First of all is the location, a phase in which the Viewer is tuition and leaves it ready for the next step. Once has it in image, it moves towards the second phase, which involves separating the different characters to conclude with the final phase, in which the reader applies a recognition process on each of the numbers, letters and symbols that has been isolated previously. The progress of the process is conditioned by the success or failure of each of its phases, i.e., each phase depends on the previous one, so one of the keys for a license plate reader get a high percentage of reliability is ensuring maximum effectiveness in each of the three phases.
