At present, a lot of the parking lot application gateway management system on the market are the license plate recognition.Nantong ring set has been committed to developing high reliability of license plate recognition system, the recognition rate is 99%.At present in our life, we have two kinds of commonly used trigger mode of license plate recognition.Peripherals are triggered and video trigger. title="nantong huanli"

a, peripheral trigger

peripherals trigger works refers to the coil, infrared, or other vehicle detector through signal, receiving the vehicle license plate recognition system the trigger signal, acquisition vehicle images, license plate automatic recognition, as well as for subsequent processing.This method has the advantage of trigger rate is high, stable performance;Defect is need for cutting the ground laid coil, construction.

2, video trigger

video trigger mode refers to the license plate recognition system using dynamic movement target sequence image analysis and processing technology, real-time checkout automobile road vehicle movement situation, found that vehicles through the capture image, recognition of license plate, and for subsequent processing.Video trigger mode without using coil vehicle detector, infrared, or other hardware.This method has the advantage of convenient construction, do not need to cut the ground laid coil, also do not need to install the car inspection device and other components, but its shortcoming is also very significant, because of the limit of algorithm, the scheme of trigger rate and recognition rate than the peripheral triggers are much lower.
