Abstract

The invention discloses a license plate distinguishing system, comprising: a light source and a light receiver connected in sequence, an optical information analysis device and a type discrimination device; wherein: the light source is configured to emit projected light to the license plate; the light receiver is configured to receive the The reflected light of the license plate on the projected light; the optical information analysis device is configured to analyze the optical information of the reflected light; the type discrimination device is configured to determine the license plate type of the license plate according to the optical information . Wherein, the light information is attribute information of reflected light, specifically, frequency information or frequency change information. Determine the color of the license plate according to the frequency information, and then determine the type, or determine whether the color of the license plate changes according to the frequency change information, and determine the type of the license plate. The system can provide effective support and reference for the selection of the license plate recognition scheme. The system has simple structure, high reliability and good use effect.

Description

technical field [0001] The invention relates to the field of license plate recognition, in particular to a license plate distinguishing system. Background technique [0002] With the substantial increase in the level of the national economy, people's living standards are also increasing. On the one hand, it is obvious that the number of cars in various regions is growing steadily on the basis of a huge base. [0003] With the increase of the number of cars, the management workload and management difficulty of the cars will increase accordingly, and new requirements will be put forward for the management of the license plate number as the identity mark of the car. Among them, the most common one is Recognition of license plates. [0004] In my country, for traditional fossil fuel vehicles, license plates with 7-digit numbers are used, and uniform regulations have been made on the size, distribution, and characters of license plates. In the prior art, multiple recognition sc...
