Abstract

The invention relates to a license plate voting method and device, computer equipment and a storage medium. Under the condition that the frame difference between a first image frame and a second imageframe is smaller than a preset frame difference threshold value, putting the first identification result into a to-be-voted queue, the second image frame being in front of the first image frame, thefirst image frame corresponding to the first identification result, the second image frame corresponding to the second identification result, and the second identification result and the first identification result being identification results adjacent to the target license plate; voting is carried out according to the recognition result in the to-be-voted queue, a license plate voting result is determined, the recognition result in the to-be-voted queue is screened, the stable recognition result is selected for license plate voting, and therefore the license plate voting result is more accurate and reliable.

Description

technical field [0001] The present application relates to the technical field of license plate recognition, in particular to a license plate voting method, device, computer equipment and storage medium. Background technique [0002] With the development of image recognition technology, license plate recognition equipment on the market has been widely used. In order to improve the accuracy of license plate recognition results, license plate voting is a relatively common post-processing method. License plate voting, that is, in continuous video sequences , for the same target license plate, put the obtained license plate recognition results in a fixed-length queue, and then integrate the recognition results in the queue to get a voting result as the license plate output. However, in the case of partial occlusion of the license plate in the related art, such as occluding a part of the lower edge of the license plate, the recognition effect of the license plate recognition algor...
