Vehicle information identification method and device

Abstract

The invention discloses a vehicle information identification method and device. The method comprises the steps of obtaining image information of a license plate in a vehicle; obtaining color information of the license plate according to the image information; obtaining number information of the license plate according to the image information; and obtaining vehicle information of the vehicle according to the color information and the number information. The purpose of obtaining more comprehensive information of the vehicle is achieved. Therefore, even if two vehicles with different license plate colors but the same license plate number enter the same parking lot from front to back, the parking time length, the parking cost and other information of each vehicle can still be accurately recorded. Therefore, the technical problems that in the prior art, if two vehicles with different license plate colors but the same license plate number enter the same parking lot from front to back due tothe fact that only the license plate number is recorded, charging is disordered, and the parking duration and parking cost of each vehicle cannot be accurately obtained are solved.

Description

technical field [0001] The present application relates to the technical field of vehicle information intelligent identification, and in particular, relates to a vehicle information identification method and device. Background technique [0002] With the rise of intelligent image recognition technology and rising labor costs, more and more parking lots are changed to intelligent or even unmanned parking lots; and the existing related parking lots only record the license plate number of the vehicle as the vehicle information of the vehicle. It is then used to bind information such as parking duration and parking fees; however, because license plates of different colors may have the same license plate number, it is generally more common to have a license plate with white letters on a blue background, which is a very common one in our daily life. One is used for small cars, including the government and political and legal departments except police cars; the other is a black plat...

Problems solved by technology

[0002] With the rise of intelligent image recognition technology and rising labor costs, more and more parking lots are changed to intelligent or even unmanned parking lots; and the existing related parking lots only record the license plate number of the vehicle as the vehicle information of the vehicle. It is then used to bind information such as parking duration and parking fees; however, because license plates of different colors may have the same license plate number, it is generally more common to have a license plate with white letters on a blue background, which is a very common one in our daily life. One type is used for small cars, including the government and political and legal departments except police cars; the other is a black plate with yellow background, which is used for large cars in general, as well as driving school coaches, motorcycles and trucks; and currently There will be cases where the color is different but the license plate number is the same

Therefore, if two vehicles with different license plate colors but the same license plate number enter the same parking lot, the system will be confused when billing, resulting in the inability to accurately obtain the parking duration and parking fee of each car; Neither the billing platform can distinguish the color of the license plate, so the above problems cannot be effectively solved

[0003] For the problems existing in related technologies, no effective solutions have been proposed yet
