License plate recognition data rematching method and system for unattended parking lot

Abstract

The invention relates to a license plate recognition data rematching method and system for an unattended parking lot. The method comprises the steps of recording a license plate to a database when a vehicle enters the parking lot, identifying the license plate when the vehicle leaves the parking lot, prompting payment information if the identification succeeds, and otherwise, calculating the similarity between the license plate of the vehicle and a license plate which does not leave the parking lot in the database; if more than one identical non-warehouse-out license plate with the highest similarity exists, carrying out re-matching fault-tolerant processing on the vehicle license plate, selecting the non-warehouse-out license plate with the highest similarity in the database for display, and carrying out payment after the user confirms the license plate. The method is realized through a license plate recognition unit, a license plate matching unit, a license plate similarity calculation unit and a control terminal in the system. The invention can solve the problems that when the parking lot is unattended, due to the fact that license plate information recognition is wrong when the vehicle enters and exits the parking lot, a user cannot pay normally, the waiting time for leaving the parking lot is long, and the user experience is poor; thus, the response processing efficiency of an operation center is improved, and unattended parking lot is truly achieved.

Description

technical field [0001] The invention relates to the technical field of devices or equipment for collecting tolls, tolls or entry fees at one or more management points, in particular to a method and system for rematching license plate recognition data for unattended parking lots. Background technique [0002] With the development of mobile Internet, artificial intelligence, electronic payment and other technologies, unattended parking lots are also developing rapidly. Many parking lots across the country have adopted the unattended parking lot model, which has achieved good results in parking management. economic benefits. [0003] In fact, the ultimate goal of the unattended parking lot is the less human and cashless intelligent management of the entire parking lot. On the basis of ensuring the safety of vehicles and property, human intervention should be minimized to realize non-sensing parking and online payment. , intelligent prompts, remote virtual services and other co...

Problems solved by technology

However, at present, the most likely cause of unattended parking lots to fail to operate normally is the inability to recognize license plates well; the current mainstream technology for license plate recognition is obtained by recognizing video image information, but due to factors such as lighting conditions, angles, and occlusions, often There are systematic errors such as recognition errors and non-recognition, which often cause the parking lot to fail to match the license plate information of the vehicle when it enters the venue, and the end user cannot pay the fee normally, and the waiting time for the exit is long. The feeling is poor, and it is often necessary to call the on-duty personnel to deal with it, which brings challenges to the "unattended" parking lot, and also causes the problem that "unattended" cannot be fully realized in fact.
