Problems solved by technology

[0006] In order to solve the existing technology, due to the different maintenance capabilities of vehicle owners, there are differences in the requirements for auxiliary means required for maintenance. However, in the prior art, there is a lack of such intelligent auxiliary tools for vehicle maintenance, resulting in the existing vehicle maintenance. It is difficult for the car owner to carry out the problem. This invention proposes a method for smart glasses to recognize the license plate and obtain vehicle information in the process of car maintenance.

Embodiment 1

[0053] Embodiment 1: A method for smart glasses to identify and obtain vehicle information through license plate recognition in the process of car maintenance, including the following steps:

[0054] S1. The operator puts on the smart glasses, switches the glasses mode to the recognition mode, and performs license plate recognition;

[0055] S2. Collect images of the vehicle through the front camera of the smart glasses;

[0056] S3. Transmitting the collected image information to the image recognition and matching module in the host computer, first performing image preprocessing, segmenting the collected vehicle image, and locating the area where the license plate is located;

[0057] Then the characters in the license plate area are individually segmented, and each character or number forms a separate image for recognition. By using an offline already trained classification model, the single character or number image is classified and recognized, and each character or number...

Embodiment 2

[0063] Embodiment 2: It has the same technical solution as Embodiment 1, the difference is: a light source is installed in the camera 15 accommodating portion and corresponds to the light source hole 8 on the second straight board 14, the microphone 11 is installed inside the first straight board 4, glasses Near the connection between the frame 2 and the convoluted bend; the speaker 12 is installed on the part of the temple 1 close to the ear when wearing smart glasses; the camera 15 is supported by the camera 15 bracket 9 and installed in the camera 15 accommodating part, and the gyroscope is used for Identify vibration signals and set different vibration signals to perform corresponding actions on smart glasses for car maintenance. Light sources, microphones, and speakers are multi-directional interactive means for maintenance using smart glasses, and realize a full range of intelligent interactions to improve the intelligence of smart glasses.

Embodiment 3

[0064] Embodiment 3: have the same technical scheme as Embodiment 2, the difference is: camera 15, light source, microphone 11 and loudspeaker 12 are connected to control panel 10, and this control panel 10 has wireless communication module, is used to receive camera 15, light source, The signal sent by the microphone 11 can be used for data processing on the received signal, and the control board 10 is equipped with a wireless signal transceiver module, and uses the signal transceiver module to send and receive signals to the remote server. The wireless signal includes, Wifi, Bluetooth, GPS, FM. Since the smart glasses are directly connected to the control board, the control board then performs signal interaction with the remote server, and the control board can also perform data processing on the received signal, that is, some simple recognition operations or other operations can be completely performed by the control board. Recognition or other processing, or pre-processing...

Abstract

The invention discloses a method of recognizing a vehicle license plate through intelligent glasses and acquiring vehicle information during a vehicle maintenance process, which belongs to the field of vehicle maintenance and aims at solving the technical problems of recognizing the vehicle license plate through the intelligent glasses and acquiring the vehicle information during the vehicle maintenance process. According to the technical points, characters in the vehicle license plate region are cut independently, each character or number forms an independent image, recognition is carried out, an offline well-trained classification model is adopted to carry out classification recognition on each character or number image, a confidence score of each recognition character is judged, and the character with the highest confidence is selected to serve as the final recognized character. The method of the invention has the effects that the vehicle information is basic information acquired by other data during the vehicle maintenance process, the intelligent glasses used for vehicle maintenance have a vehicle license plate recognition function, and an important role is played.

Description

technical field [0001] The invention belongs to the field of automobile maintenance, and in particular relates to a method for smart glasses to identify and obtain vehicle information through license plate identification during the automobile maintenance process. Background technique [0002] When domestic car owners have problems or need maintenance, most of them still rely on 4s shops. But 4S stores have two obvious disadvantages, expensive and time-consuming. [0003] When people settle for the next best thing and choose the plethora of informal repair shops, although it is convenient and cheap, it is tantamount to entrusting their body to those without formal qualifications. When doctors with medical qualifications send their children to teachers without teaching qualifications, they are a little bit discouraged. [0004] There are also some hands-on skills, car owners who are willing to do it themselves, because they have not gone through professional learning, they w...
