3.Because licenseplate is efficient in identifing vehicles , LicensePlate Recognition(LPR)is foundamental in ITS , In recent years , as the technology of manufactory progress .
5.An improved vehicle licenseplate tilt correction method based on Sobel edge detector and a new plate pre-processing algorithm based on area filter is present.
8.The system fuses the information of the Car Model exported by CMIS, licenseplate exported by LicensePlate Recognition System, and the data saved in the non-contacting IC card to obtain toll decree and hence greatly improves the reliability of the system.
9.A recognition method of licenseplate character is presented, which extracts the space structure feature of Chinese character and then recognizes them using multilevel classifier.
10.This paper solves one of critical technology problems in LPR—license-plate Chinese character recognition, This study has biggish theory meaning and practice value.
