In some optional implementation manners of this embodiment, the obtaining of the information to be published includes: and acquiring the current position of the vehicle in response to receiving flameout information sent by the vehicle corresponding to the license plate number. Information indicating that the vehicle stalls at the current position is generated as the information to be released. The issuing terminal starts a navigation function to collect position information of the vehicle. When the vehicle is powered off and depends on, the vehicle sends flameout information to the issuing terminal. The issuing terminal may generate information indicating that the vehicle stalls at the current position as the information to be issued.
In this embodiment, the binding relationship between the telephone number of the issuing terminal and the license plate number is registered in the server in advance. The server may be a public network server or a server in NB-IoT (Narrow Band Internet of Things). And encrypting the license plate number through a preset encryption algorithm to obtain a ciphertext. For example, the license plate "suxyz" is subjected to MD5 encryption to obtain "653993D 755C0AD44EFEE7A3AD4B7D8E 6". The encryption can be carried out by the terminal or the server.
And step 203, generating the network release address according to the ciphertext.
In this embodiment, the above MD5 password is further split:
6539:93D7:55C0:AD44:EFEE:7A3A:D4B7:D8E6
the addresses thus generated were https://6539:93D7:55C0: AD44: EFEE:7A3A: D4B7: D8E 6: 80/index
The issuing terminal can use NB-IoT (SIM card applies for an IPV6 address in advance, and each mobile phone can apply for an IPV6 address for issuing the information to be issued.
Optionally, an existing public network address may also be used for address mapping, so that a server needs to be erected:
for example, the public network address is: 101.2.3.2
The public network server generates data corresponding to the current license plate:
https://101.2.3.2/653993D755C0AD44EFEE7A3AD4B7D8E6/index.html
and step 204, generating a hypertext transfer protocol page according to the information to be issued.
In this embodiment, a hypertext transfer protocol page, such as an html page, accessible via the URL address is generated according to the information to be published. The hypertext transfer protocol page may be generated using a general web page generation tool.

Setting the mobile phone authority, setting socket information, setting connection configuration information, and setting monitoring and encryption. And then published by the network address generated in step 203. There are two methods for system release:
the method comprises the following steps: with NB-IoT SIM cards, each handset can apply for an IPV6 address and issue.
The second method comprises the following steps: with network mapping: because the public network IP is on the router, when the outer network accesses, the outer network needs to pass through the router, and port mapping needs to be carried out on the router, so that the access port of the inner network website is opened.
With continued reference to FIG. 3, a flow 300 of yet another embodiment of a method for publishing information in accordance with the present application is shown. The method for releasing the information is applied to the reading terminal and comprises the following steps:
In the present embodiment, an executing subject (e.g., the terminal device shown in fig. 1) of the method for distributing information may obtain an image including license plate information by scanning a license plate. Or selecting an image including license plate information from an album of the reading terminal. A new button can be added to the picture browsing interface to read the release information corresponding to the license plate in the picture.
In the present embodiment, the license plate number can be recognized from the image according to an existing image recognition method. For example, using OCR (Optical Character Recognition).
In some optional implementations of the embodiment, identifying the license plate number from the image, as shown in fig. 4, includes the following steps:
step 3021, image processing is performed on the image.
Generally, a conclusion is obtained according to analysis of a field environment and a shot image, automatic backlight processing, automatic white balance processing, automatic exposure processing, automatic explosion processing and the like of a camera are realized, and image scaling, noise filtering, contrast enhancement and the like are performed on the image.
And step 3022, positioning the license plate from the image after the image processing.
The license plate is generally positioned by adopting algorithms such as projection analysis, connected domain analysis, machine learning and the like to detect the license plate according to information such as texture features, color features, shape features and the like in the acquired image.
And step 3023, performing character segmentation on the license plate, and extracting at least one character.
The main idea of character segmentation is that based on a binarization result or an edge extraction result of a license plate, information such as structural features of characters, similarity between characters, intervals between characters and the like is utilized, on one hand, single characters are respectively extracted, and processing of special conditions such as adhesion and broken characters is also included. On the other hand, characters with similar width and height are classified into one class so as to remove the license plate frame and some small noises. The algorithms generally used are: projection analysis, connected domain analysis, character clustering, template matching and the like.
Step 3024, identifying a license plate number based on the at least one character.
The character recognition algorithms currently in use are: template matching method, artificial neural network method, support vector machine method and Adaboost classification method. After machine learning or matching with the character database template, the result with the highest matching degree is selected to be output
In this embodiment, the license plate number is encrypted by a predetermined encryption algorithm to obtain a ciphertext. For example, the license plate "suxyz" is subjected to MD5 encryption to obtain "653993D 755C0AD44EFEE7A3AD4B7D8E 6".
And step 304, generating a first network publishing address according to the ciphertext.
In this embodiment, the above MD5 password is further split:
6539:93D7:55C0:AD44:EFEE:7A3A:D4B7:D8E6
the addresses thus generated were https://6539:93D7:55C0: AD44: EFEE:7A3A: D4B7: D8E 6: 80/index.
If the reading terminal is connected with a public network, a mapping address of the public network can be generated:
for example, the public network address is: 101.2.3.2
The public network server generates data corresponding to the current license plate:
https://101.2.3.2/653993D755C0AD44EFEE7A3AD4B7D8E6/index.html
In this embodiment, the information issued by the owner can be viewed by accessing the address generated according to the license plate. For example, a car moving phone number left when temporarily parking a car. The reading terminal can directly click the number to contact the owner of the vehicle. Other means may be used to leave messages to the owner, such as a message board.
In some optional implementations of this embodiment, the method further includes: and acquiring a second network release address generated in advance according to the license plate number bound with the reading terminal. A hypertext transfer protocol page is generated based on the published information. The hypertext transfer protocol page is posted via the second network posting address. The read terminal can add the read information into the information of the read terminal and then transmit the information. And adding the information into the information system of the user to form a connection. The information read by scanning the license plate of other people can be transmitted to the mobile phone of the user and sent out again, and the following table shows that:
TABLE 4
With continued reference to fig. 5, fig. 5 is a schematic diagram of an application scenario of the method for publishing information according to the present embodiment. In the application scenario of FIG. 5, the owner of the license plate "Zhe xxx" 501 temporarily stops the vehicle at the gate of another person. In order not to influence the trip of others, the mobile phone (issuing terminal) of the owner of the vehicle is used for leaving the information 502 waiting for issuing in the contact way of moving the vehicle. And the issuing terminal generates an HTML webpage according to the information to be issued. The address https:// [6539:93D7:55C0: AD44: EFEE:7A3A: D4B7: D8E 6: 80/index.html is generated by the issuing terminal after being encrypted according to the license plate number 'Zhe xxx'. And the releasing terminal starts HTTP service and releases HTML web page on the website. When a passer wants to contact a car owner, a license plate photo can be shot through a mobile phone (a reading terminal) of the passer, then the reading terminal identifies a license plate number, and the car owner is calculated according to the encryption of the license plate number to publish the vehicle related information on a website https:// [6539:93D7:55C0: AD44: EFEE:7A3A: D4B7: D8E 6: 80/index. The reading terminal accesses the website and opens the HTML webpage, so that the information issued by the owner can be seen. The passerby can then contact the owner of the vehicle to move the vehicle according to the telephone number left by the owner of the vehicle.
According to the method provided by the embodiment of the application, after the user is bound with the current automobile license plate, the user can inform the mobile phone of the current condition and information, and the mobile phone can automatically start the service to be used as a content provider to broadcast to other users or wait for other users to request the service. Other users can directly scan the license plate and can know the information issued by the user. Therefore, the driver, the automobile and the outside personnel can share the information, and the automobile information can be shared among different users through the mobile phone.
