Problems solved by technology

[0002] With the rapid development of society, the automatic license plate recognition system has been widely used, but the installation angle of the automatic recognition camera of the license plate in the prior art is not the best angle, resulting in a relatively low recognition rate of the license plate. In this case, work is required When personnel go to the scene to manually adjust the license plate recognition camera according to the recognition effect of the license plate recognition camera, it takes a lot of time and labor costs, and the staff can only adjust the angle of the license plate recognition camera based on experience

Abstract

The present invention is applicable to the technical field of license plate recognition, and provides a camera angle adjustment method, system, storage medium, and electronic equipment, wherein a camera angle adjustment method includes the following steps: acquiring multiple license plate photos; Photos, generate multiple deflection photos; identify all deflection photos, select deflection photos with successful license plate recognition, and record the deflection angle collection in each deflection photo with successful license plate recognition as A j ;Calculate; set the camera according to B t deflection angle in α t Adjust in turn, and obtain each time according to the deflection angle α t Adjusted corresponding license plate recognition rate C t , take the corresponding deflection angle as the target adjustment angle of the license plate recognition camera. Through the method for adjusting the camera angle of the present invention, the times of adjusting the camera angle are reduced, the adjustment time is saved, and the recognition rate of successful license plate recognition is improved.

Description

technical field [0001] The present invention relates to the field of license plate recognition, in particular to a camera angle adjustment method, system, storage medium, and electronic equipment. Background technique [0002] With the rapid development of society, the automatic license plate recognition system has been widely used, but the installation angle of the automatic recognition camera of the license plate in the prior art is not the best angle, resulting in a relatively low recognition rate of the license plate. In this case, work is required When personnel go to the scene to manually adjust the license plate recognition camera according to the recognition effect of the license plate recognition camera, it takes a lot of time and labor costs, and the staff can only adjust the angle of the license plate recognition camera based on experience. Contents of the invention [0003] The purpose of the present invention is to provide a camera angle adjustment method, sys...
