License plate recognition system in the application of intelligent residential area

2022-12-02 00:00:00

Same as the license plate recognition technology matures and development, and its application have been widely promoted.In the context of current residential parking situation, license plate recognition system has gradually become a part of the parking in people life, and is playing an increasingly important role.As a way to monitor essential technological means, believe that the future for license plate recognition system existing problem must lead the whole intelligent transportation industry into a new stage of development.Several main problems existing in the current parking license plate recognition system:

1, the license plate location and character segmentation
2, the contradiction between high resolution and can identify
3, the adaptability of license plate recognition system in urgent need to strengthen
4, license plate recognition system for dirty license plate recognition effect is not good

environment is the main factor affecting the license plate recognition, when collecting vehicle image, due to environmental changes drastically, light Bai Tianguang stronger and weaker at night, different light and backlight, morning and afternoon light direction is different also, when captured images are greatly influenced by ambient light, high speed, the dynamic range of acquisition equipment and so on all make the imaging quality is difficult to get effective guarantee.When recognition algorithm thought license plate to achieve the best position of imaging system to trigger the system start filming, the trigger equipment reliability and response speed has higher requirements.So to solve the problems of the environment caused the low recognition rate, depends on the camera sensitive parts processing of external environment.

with the widespread application of the parking lot system, parking management system in the construction of intelligent community system with the advantages are obvious.Along with the expansion of intelligent community system construction throughout the country and promotion, security level unceasing enhancement, the expansion and development of security products up to the car park entrance guard in the IC card management system in the 21st century intelligent building shows a great potential for development and rising space.Residential intelligent parking lot management system according to the operation type can be divided into: mechanical parking lot management system, remote control car park management system;According to the distribution mode is divided into: plane three-dimensional parking lot parking lot management system, management system;According to the charging methods can be divided into: artificial charge parking lot management system, IC card parking system.Among them, in the intelligent community system, license plate recognition system to gradually replace the IC card charging parking system used in residential area, is currently a good cost performance car park management system type.
