Embodiment Construction

[0057] The present invention discloses a motor vehicle coupling identification system, including distributed terminal, check-based station, and central device, which provides a license plate relay identification method based on cross-lentic location prediction techniques, mainly based on the identification system. The step is: the central device receives the license plate number information you want to relay, that is, TC s = {IMG s Num s , T s L s } (Including: the image, license plate number, time and geographic location of the target license plate vehicle, position prediction of the target license plate (vehicle). The specific process is as follows:

[0058] First, the central device is based on the license plate number information Tc that is received by the receiving relay. s Under which position of the predictive target license plate may appear under the camera, and predict a set of locations (ie, cross-mirror position prediction, narrowing the scope of the target license plat...

Abstract

The present invention relates to a motor vehicle license plate relay recognition system and license plate relay recognition method, comprising a distribution terminal, a bayonet base station and a central device. The distribution terminal is used for collecting and processing image information; the bayonet base station is fixedly installed in each The traffic bayonet is used to collect and process image information on the one hand, and information transfer between distributed terminals and central equipment on the other hand; on the one hand, the central equipment is used to manage all the distributed terminals and bayonet base stations in the system and coordination, on the other hand, according to the received license plate information, the location of the target license plate is predicted. By predicting and calculating the cross-mirror position of the target vehicle, and cyclically executing the relay recognition process of the license plate, the system realizes the motor vehicle license plate relay recognition, which can greatly improve the real-time performance of the target motor vehicle license plate recognition and positioning, and has broad practical prospects.

Description

Technical field [0001] The present invention relates to the field of computer, intelligent identification, and more particularly to a motor vehicle license plate relay identification system and license plate relay identification method. Background technique [0002] The whole process of the transportation system is real-time and accurate to obtain the motor vehicle license, which is of great significance for the implementation and management of intelligent transportation systems. [0003] At present, the image identification of the target motor vehicle sign mainly depends on the urban monitoring system built in the transportation management department. If you want to track a motor vehicle, you can only enter the target motor vehicle card information, then mainly depend The calculation resource of the data center is identified and searched from a massive image. Since the target license plate is identified from a massive image, it takes a long time to search, and the target vehicle...
