Vehicle license-plate identification device

Abstract

The invention discloses a vehicle license-plate identification device. The device comprises a barrier gate column, a barrier gate rail, an image collection camera and an image identification host. Theimage collection camera is arranged on the barrier gate rail. The image identification host is arranged on the barrier gate column. The image collection camera is in communication connection with theimage identification host. The barrier gate rail is in mechanical connection with the barrier gate column, and can rotate along a fixed shaft. By adopting the technical scheme of the invention, the image collection camera and the image identification host are separately arranged; and on installation, an existing barrier gate in an entrance / exit is fully utilized, punching and ground breaking construction are avoided, installation does not need to be impacted for an on-site environment in practical application, convenience is brought for on-site construction, and a practical use effect is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of automatic vehicle identification, in particular to a license plate identification device. Background technique [0002] At present, license plate recognition devices are installed at the entrance and exit of the parking lot to facilitate the automatic collection of vehicle information entering and leaving the parking lot. Usually, the entrance and exit vehicle recognition cameras are installed on the edge of the traffic lane, installed through the column, and recognize the license plate of the vehicle driving in the traffic lane. [0003] There are following defectives in prior art: [0004] First, there is no way to ensure that the camera shooting direction is in the same direction as the driving lane, and it cannot be guaranteed that the captured license plate is in the horizontal direction, and there is an oblique angle, resulting in a low license plate recognition rate. [0005] Second, the on-site ...

AI Technical Summary

Problems solved by technology

[0004] First, there is no way to ensure that the camera shooting direction is in the same direction as the driving lane. It cannot guarantee that the captured license plate is in the horizontal direction, and there is an oblique angle, resulting in a low license plate recognition rate.

[0005] Second, the on-site environment makes the installation more troublesome and the construction cost is relatively high
