Abstract

The invention discloses a vehicle license plate recognition method and system. The vehicle license plate recognition method includes acquiring license plate information of several vehicles in driveways by a shooting unit to obtain acquisition videos, acquiring license plate information of each frame in the acquisition videos, judging whether license plate numbers in the license plate information are new license plate numbers or not, if not, arranging the license plate information into corresponding arrays according to similarity of the license plate information, that is, arrays having highest similarity, and judging whether the maximum difference between the frame numbers of the license plate information in the arrays is up to a first preset value or not, and if yes, voting the license plate number in the arrays to obtain available license plate numbers. One shooting unit can acquire license plate information of the vehicles in the driveways, paving inductors and mounting stroboscopic lights and cameras in each driveway are omitted, and construction increment and difficulty adding are avoided.

Description

technical field [0001] The invention relates to the field of identification, in particular to a method and system for identifying a license plate. Background technique [0002] At present, the expressway license plate recognition generally adopts the single-frame capture recognition method, that is, the cars on each lane trigger the corresponding strobe lights and cameras to capture the current image through the sense of ground pressure, and the background processor processes the captured image. , to get a single license plate recognition result. [0003] However, with this method, it is necessary to pave each lane on the expressway, and install a strobe light and a camera for each lane, which increases the construction cost and difficulty. Contents of the invention [0004] In view of this, the present invention provides a method and system for license plate recognition to solve the problem of construction cost caused by laying ground sense in each lane and installing a ...
