Embodiment 1

[0027] figure 1 It is a schematic flow chart of a method for identifying a license plate number provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the license plate number is recognized by a local chip in a license plate recognition device. This method can be applied to a local chip Among them, it is executed by a device for recognizing the license plate number, which device can be implemented in the form of software and / or hardware.

[0028] Wherein, the local chip may include an AI (Artificial Intelligence, artificial intelligence) chip capable of processing a large number of computing tasks in artificial intelligence applications. The amount of calculations that AI chips can perform in parallel is far greater than that of CPUs (Central Processing Units, central processing units), and AI chips are dozens or even thousands of times faster than CPUs in training and reasoning AI algorithms. more efficient.

[0029] Such as ...

Embodiment 2

[0063] figure 2 It is a structural diagram of a device for recognizing license plate numbers provided by Embodiment 2 of the present invention. The device is configured in a local chip and includes: a target image acquisition module 210 , a target character recognition module 220 and a target license plate number recognition module 230 .

[0064] Wherein, the target image acquisition module 210 is used to acquire the target image; the target image includes the target vehicle; the target character recognition module 220 is used to determine the license plate area in the target image based on the local chip, and extract the target characters in the license plate area; The target license plate number recognition module 230 is configured to identify the target license plate number of the target vehicle based on the target characters.

[0065] Optionally, the device also includes:

[0066] An image capture module, used to capture images to be processed including the target vehicl...

Embodiment 3

[0081] Figure 4 It is a schematic structural diagram of an electronic device provided by Embodiment 3 of the present invention. Figure 4 A block diagram of an exemplary electronic device 40 suitable for implementing an embodiment of the invention is shown. Figure 4 The electronic device 40 shown is only an example, and should not impose any limitation on the functions and application scope of the embodiments of the present invention.

[0082] Such as Figure 4 As shown, electronic device 40 takes the form of a general-purpose computing device. Components of the electronic device 40 may include, but are not limited to: one or more processors or processing units 401 , a system memory 402 , and a bus 403 connecting different system components (including the system memory 402 and the processing unit 401 ).

[0083] Bus 403 represents one or more of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, a pr...

Abstract

The embodiment of the invention discloses a license plate number recognition method and device, electronic equipment and a storage medium, and the method is applied to a local chip, and comprises thesteps: obtaining a target image; wherein the target image comprises a target vehicle; determining a license plate area in the target image based on the local chip, and extracting target characters inthe license plate area; and based on the target character, identifying a target license plate number of the target vehicle. Through the technical scheme of the embodiment of the invention, the technical problems that the license plate recognition time is long and the device response speed is low due to the fact that the license plate recognition device needs to upload the license plate image to the cloud server for recognition are solved, and the technical effect of improving the license plate recognition speed through the local chip in the license plate device is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to a method, device, electronic device and storage medium for recognizing a license plate number. Background technique [0002] With the development of intelligent transportation systems, license plate recognition equipment is widely used in various fields. [0003] In order to ensure good traffic order or social security, products such as license plate recognition equipment based on license plate recognition technology are widely used in property communities, commercial buildings and government agencies. [0004] However, the existing license plate recognition equipment is to send the captured image to the cloud server, so that the cloud server can perform license plate recognition, and the recognition result is sent back to the local license plate recognition device. Identify technical issues with low productivity. Contents of the invention ...
