Description

Technical Field

[0001] The present invention relates to the technical field of license plate recognition equipment, and in particular to a rapid license plate recognition equipment for a barrier gate. Background Art

[0002] Because existing recognition modules are mostly installed outdoors, excessive light can cause license plate reflections, reducing recognition rates. Furthermore, recognition rates can be affected by fog, heavy rain, and other weather conditions. Therefore, it's necessary to adjust the camera's position to obtain a clearer image of the license plate.

[0003] Furthermore, in some parking lots or roads, vehicles may be traveling in different directions and parked at different locations, necessitating adjustments to the camera's position to ensure accurate license plate recognition for vehicles traveling in different directions. The camera's mounting position is fixed, and the lens in the camera is retracted to collect license plate information from vehicles parked at different distances. However, since the camera's mounting angle is fixed, adjusting the lens's telescopic adjustment makes it difficult to collect license plate information from vehicles parked close together. Summary of the Invention

DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] See also Figures 1-13 As shown, the present invention is a license plate rapid recognition device for a barrier gate, which is installed at the entrance of a passage. The barrier gate includes an outer shell 1, a transmission system and an identification module;

[0057] The transmission system and the identification module are installed in the outer shell 1, and one end of the identification module extends from the slot 101 of the outer shell 1;

[0058] The control end of the transmission system is electrically connected to the transmission end of the identification module. The identification module transmits a control signal to the transmission system and is used to control the release or blocking of vehicles on the channel.

[0059] The recognition module collects the vehicle image including the license plate through the acquisition device 4, and converts the color image of the vehicle image into a grayscale image to reduce the amount of data;

[0060] Then, through methods such as texture analysis, the license plate area is accurately extracted from the processed image, and the recognized license plate number and other results are output in text, image or other forms, such as displaying on a display screen, storing in a database or transmitting to other systems for further processing;

[0061] At the same time, the acquisition device 4 is connected to the network cable, and the extracted data is uploaded through the network cable and compared with the license plate information stored in the memory;

[0062] If the same license plate information exists, the recognition module transmits a release signal to the transmission system;

[0063] If the same license plate information does not exist, the recognition module transmits a blocking signal to the transmission system.

[0064] Thus, through the installed collection equipment 4, the automated management of vehicles, such as parking lot management, access control management, traffic flow monitoring, etc., can be achieved, reducing manual intervention and improving management efficiency and accuracy.

[0065] The composition structure of the recognition module, refer to Figures 8-13 The recognition module includes a fixed base 2 and a collection device 4. One end of the collection device 4 is connected to a cover 3, which is fitted on the end of the fixed base 2. The other end of the collection device 4 is connected to the fixed base 2 through a swing component 5. The swing component 5 drives the collection device 4 to reciprocate around the cover 3.

[0066] Because existing recognition modules are mostly installed outdoors, excessive light can cause license plate reflections, reducing recognition rates. Furthermore, recognition rates can be affected by fog, heavy rain, and other weather conditions. Therefore, it's necessary to adjust the camera's position to obtain a clearer image of the license plate.

[0067] Furthermore, in some parking lots or roads, vehicles may be traveling in different directions and parked at different locations, necessitating adjustments to the camera's position to ensure accurate license plate recognition for vehicles traveling in different directions. The camera's mounting position is fixed, and the lens in the camera is retracted to collect license plate information from vehicles parked at different distances. However, since the camera's mounting angle is fixed, adjusting the lens's telescopic adjustment makes it difficult to collect license plate information from vehicles parked close together.

[0068] The present application drives the acquisition device 4 to move by the swing component 5, thereby changing the overall tilt angle of the acquisition device 4, thereby obtaining a larger imaging viewing angle, making it easier to obtain a clearer license plate image.

[0080] In this application, the swing motor 502 drives the transmission rod 501 to rotate. Since a rotating disk 503 is installed at the end of the transmission rod 501, a cylinder 504 is eccentrically distributed on the rotating disk 503;

[0081] The rotating disk 503 drives the rod body 505 to swing around the pin shaft 506 through the cylinder 504, and the other end of the rod body 505 drives the ring sleeve 403 and the fuselage 401 to swing, thereby changing the inclination angle of the fuselage 401, thereby obtaining a larger imaging angle and facilitating the acquisition of a clearer license plate image.

[0082] The fixing base 2 is provided with a spherical groove 203 at the end of the slot hole 101. The cover body 3 includes a spherical cover 301.
