Referring to fig. 1, an application scenario of the information query method in the embodiment of the present application includes:
the system comprises a terminal 101, an information inquiry device 102, an image acquisition device 103 and a storage server 104;
although the terminal 101 is represented by a pattern of a smart phone, the type of the terminal 101 is not limited to the smart phone, and may be a terminal device such as a tablet computer, a laptop portable computer, a desktop computer, a self-service terminal, and a wearable electronic device; the information query apparatus 102 may be specifically a computer device capable of performing data processing, such as a server, an independent physical server, a server cluster or distributed system composed of a plurality of physical servers, or a cloud server providing basic cloud computing services, such as a cloud database, cloud computing, big data and an artificial intelligence platform.
The image capturing device 103 is configured to capture a parking field image of a parking lot in a certain area of the parking lot, which is determined by a photographing angle of view of the image capturing device 103, and as shown in the drawing, the image capturing device 103 may capture a parking field image of a plurality of parking spaces within the photographing angle of view and a vehicle parked in each parking space.
The storage server 104 is used for storing data, and may actively send data to the information query device 102, or return data corresponding to a data request to the information query device 102 based on the data request sent by the information query device 102.
The information query device 102 may provide a parking space query service for the user of the terminal 101, that is, the user of the terminal may query the parking space where the user parks his vehicle in the parking lot through the information query device 102. The specific process of providing parking space inquiry by the information inquiry device in the embodiment of the present application will be described in detail below. The following describes an information query method in the embodiment of the present application with reference to an application scenario shown in fig. 1:
referring to fig. 2, an embodiment of an information query method in the embodiment of the present application includes:
201. acquiring parking space information of a target vehicle and license plate information of the target vehicle corresponding to a parking field image of the target vehicle;
the method of the embodiment can be applied to an information inquiry device. When the parking space inquiry service is provided, the information inquiry device acquires parking space information of a target vehicle and license plate information of the target vehicle corresponding to a parking field image of the target vehicle, wherein the target vehicle is a vehicle parked in a parking lot, and therefore the parking field image is a field image of a parking space where the target vehicle is located, and the field image comprises an image of the target vehicle and an image of the parking space; parking space information is any information relating to the parking space of the target vehicle, which may be, for example, the specific location of the parking space; the license plate information may be a license plate number of the target vehicle.
The parking space information and the license plate information can be obtained by carrying out image recognition on the parking field image, namely, the parking field image is processed and analyzed according to an image recognition algorithm, and the license plate information corresponding to the image of the target vehicle and the parking space information corresponding to the image of the parking space are recognized. The specific image recognition algorithm is not limited, and may be, for example, an image recognition algorithm based on a neural network, an image recognition algorithm based on wavelet moments, or the like.
The license plate information corresponds to the target vehicle, and meanwhile, the parking space information also corresponds to the parking space of the target vehicle, so that the parking space information of the target vehicle and the license plate information of the target vehicle are associated, and the corresponding parking space information can be inquired according to the license plate information of the target vehicle.
202. Receiving a parking space inquiry request sent by a terminal, and determining parking space information of a target vehicle according to license plate information of the target vehicle carried by the parking space inquiry request;
when a terminal user needs to inquire the parking space for parking the vehicle, a parking space inquiry request is sent to the information inquiry device through the terminal, and the request carries the license plate information of the target vehicle of the terminal user. The information inquiry device responds to the request, and because the association relationship between the parking space information of the target vehicle and the license plate information of the target vehicle is established, the information inquiry device can inquire the parking space information corresponding to the license plate information according to the license plate information carried in the request.
203. Returning the parking space information of the target vehicle to the terminal so that a user of the terminal determines the parking position of the target vehicle;
after the parking space information of the target vehicle is determined according to the parking space query request of the terminal user, the information query device returns the parking space information of the target vehicle to the terminal, so that the terminal user can determine the parking position of the target vehicle according to the parking space information, and the parking space can be found quickly.
In the embodiment, the parking space information of the target vehicle and the license plate information of the target vehicle corresponding to the parking field image of the target vehicle are obtained, and the association relationship between the parking space information of the target vehicle and the license plate information of the target vehicle is established, so that when a parking space inquiry request of a terminal user is received, the parking space information of the target vehicle can be determined according to the license plate information of the target vehicle carried by the request, and after the parking space information is returned to the terminal user, the terminal user can quickly find the parking space for parking the vehicle according to the indication of the parking space information, thereby greatly facilitating the vehicle finding of a vehicle owner in a parking lot, and greatly reducing the time for the vehicle owner to find the vehicle.
The embodiments of the present application will be described in further detail below on the basis of the aforementioned embodiment shown in fig. 2. Referring to fig. 3, another embodiment of the information query method in the embodiment of the present application includes:
301. acquiring parking space information of a target vehicle and license plate information of the target vehicle corresponding to a parking field image of the target vehicle;
the parking lot images may be acquired by an image acquisition device installed in the parking lot. In a preferred embodiment, the image capturing device may be configured with an image capturing element, and may further be configured with a data processing element based on an edge computing technology, where the data processing element is configured to analyze and process a parking lot image captured by the image capturing element according to a preset image recognition algorithm, and the data processing element may be a CPU with certain computing capability, and more specifically, the CPU may be an STM32 single chip microcomputer, and the use of the STM32 single chip microcomputer may effectively reduce power consumption and improve the operating capability of the CPU.
The edge computing technology is an open platform integrating core capabilities such as network, computing, storage, application and the like on one side close to a data source, and provides a nearest-end service nearby. Therefore, in this embodiment, the image capturing device is configured with the data processing element on the side of the data source (i.e., the image capturing element) based on the edge computing technology, so that the data processing element can respond to and process the image captured by the image capturing element in time, i.e., provide data computing service in time. Therefore, the image acquisition equipment is configured based on the edge computing technology, so that a faster network service response can be generated, data computing and processing services can be provided in real time, and the data processing efficiency is improved. Meanwhile, data are only transmitted in the local equipment, so that data transmission with the outside is not needed, and safety and privacy protection can be better realized.
And the data processing element analyzes and processes the parking field image to obtain the parking space number of the target vehicle and the license plate information of the target vehicle. Specifically, in the parking lot, each parking space is identified by a physical display mark to have a corresponding number, and the image capturing device for capturing the image of the parking site also has a corresponding number. Therefore, the image acquisition equipment identifies the vehicle image in the parking field image to obtain the license plate information of the target vehicle; the parking space image in the parking field image is identified, and the number of the parking space of the target vehicle can be obtained. And then, the image acquisition equipment sends the number of the image acquisition equipment, the license plate information of the target vehicle and the parking space number of the target vehicle to an information inquiry device, the information inquiry device determines the position information of the image acquisition range of the image acquisition equipment in the parking lot according to the number of the image acquisition equipment, and determines the parking space information of the target vehicle by combining the position information and the parking space number of the target vehicle.
The entity display mark of the parking space number can be an LED display screen or display marks such as characters printed on a wall body, a column and other bearing objects, the specific form of the display mark is not limited, and the display mark of the parking space number can be identified.
In this embodiment, when determining the position information of the image acquisition range of the image acquisition device in the parking lot, the information query device receives the parking lot map data sent by the storage server, where the parking lot map data includes a mapping relationship between the number of each image acquisition device and the image acquisition range. And then, the information inquiry device determines the image acquisition range of the image acquisition equipment according to the mapping relation and the number of the image acquisition equipment, and determines the position information of the image acquisition range in the parking lot.
The image capture range of the image capture device refers to the range of the object captured by the image capture device, and the position information of the image capture range in the parking lot is the position of the captured range of the object in the parking lot.
For example, after a camera with the number a (hereinafter referred to as an a camera) identifies a parking field image to obtain a parking space number (assumed as number 05) of a target vehicle and license plate information of the target vehicle, the number of the camera, the license plate information of the target vehicle and the parking space number of the target vehicle are sent to an information inquiry device, the information inquiry device determines position information of an image acquisition range of the camera in a parking lot according to the number of the a camera, and if the image acquisition range of the a camera is a parking space of 1-10 numbers in a first floor a of the parking lot, the image acquisition range can be determined to be located in the first floor a of the parking lot. And, since it is determined that the parking space number of the target vehicle is 05, combining the position information of the image acquisition range in the parking lot (i.e. the first floor a area of the parking lot) and the parking space number 05 of the target vehicle, it can be determined that the parking space information of the target vehicle is the number 05 parking space in the first floor a area of the parking lot.
It is described above that the parking space information of the target vehicle is obtained by combining the position information of the image capturing range in the parking lot and the parking space number of the target vehicle, but the entity display mark of the parking space may also directly display the parking space information, for example, in the above example, the entity display mark directly displays the parking space information as "first floor a zone 05", so that the image capturing device can directly recognize the parking space information of the target vehicle, and the information inquiring device does not need to perform the step of "combining the position information and the parking space number of the target vehicle".
In this embodiment, there are other ways to obtain the parking space information of the target vehicle, for example, the image acquisition device transmits the parking field image to the information query device after acquiring the parking field image, and the information query device performs analysis processing on the parking field image according to an image recognition algorithm to obtain the corresponding parking space information of the target vehicle and the license plate information of the target vehicle. In this case, the image capturing apparatus may not need to be provided with a data processing element. The present embodiment does not limit the manner of acquiring the parking space information of the target vehicle.
When the data of the number of the image acquisition equipment, the license plate information of the target vehicle and the parking space number of the target vehicle are sent, the image acquisition equipment forms a description field of the data based on a preset data reporting mechanism, and sends the description field to the information inquiry device. Because the description field is determined based on the mechanism, the description field also has a certain preset format, and the specific format is as follows: the number of the image acquisition device, the parking space number of the target vehicle and the license plate information of the target vehicle are all one sub-field of the description field, and each sub-field has a preset number of digits.
After receiving the description field, the description field is determined according to the preset data reporting mechanism, so that the information query device can reversely derive the description field according to the preset data reporting mechanism to identify the content of each subfield, thereby obtaining the information of the number of the image acquisition device, the parking space number of the target vehicle and the license plate information of the target vehicle.
For example, the number of the image capturing device is 10 bits, the number of the target vehicle is 2 bits, and the license plate information of the target vehicle is 10 bits, and the number of the target vehicle is less than the predetermined number of bits and is supplemented with 0. Assuming that the number of a certain camera is 12345, the corresponding subfield is 0000012345; if the number of the parking space of the target vehicle identified by the camera is 05, the corresponding subfield is 05; the license plate information of the target vehicle identified by the camera is cantonese B12345, and the corresponding subfield is 000 cantonese B12345. Therefore, the description field composed of the foregoing subfields can reflect information such as the number of the image capturing device, and the information querying device performs reverse derivation on the description field based on the preset data reporting mechanism, so as to obtain information such as the number of the image capturing device.
The information such as the serial number of image acquisition equipment is transmitted in a field describing mode, a plurality of information are bundled to be transmitted in the mode, compared with independent transmission among a plurality of information, the operation of data transmission can be greatly reduced, the efficiency of data transmission is improved, the information inquiry device can also determine which information are corresponding, and the information inquiry device can conveniently identify the transmission data.
When the description field is transmitted, the transmission may be performed based on a Message Queue Telemetry Transport (MQTT) protocol. The MQTT protocol belongs to a transmission protocol of the internet of things, is simpler, lighter and easy to use, mainly provides a subscription/publication mode, and is particularly suitable for limited environments (such as limited environments with low bandwidth, high network delay, unstable network communication and the like). The MQTT protocol can operate in embedded devices with limited processor and memory resources, and provides one-to-many message publishing using a publish/subscribe messaging model to decouple applications. That is, one MQTT client sends a message of a specific topic, and can support multiple subscribers to subscribe simultaneously.
For example, the notebook and the mobile phone both subscribe to a message with a temperature as a message topic, and when the temperature sensor issues the message of the temperature, both the notebook and the mobile phone receive the temperature issued by the temperature sensor.
Therefore, when the description field is transmitted based on the MQTT protocol, the information query device subscribes to a preset topic, the topic name of the preset topic comprises the name of the description field, and when the image acquisition device publishes the description field corresponding to the preset topic based on the MQTT protocol, the information query device can receive the description field corresponding to the preset topic.
For example, the subject name of a preset subject is "/pvupload/[ data ]", where "[ data ]" is the name of the description field.
In this embodiment, the image acquisition device may send the parking space number of the target vehicle and the license plate information of the target vehicle once every preset time (e.g., every 5 minutes), and the information query device may not send a response message for receiving the data to the image acquisition device when receiving the parking space number of the target vehicle and the license plate information of the target vehicle. Because the parking space number and the license plate information are transmitted every other preset time length, even if a certain transmission is unsuccessful, the parking space number and the license plate information are continuously transmitted to the information inquiry device after the preset time length, and therefore the information inquiry device can receive corresponding data. The operation of the information inquiry device can be reduced without sending a response message, and the processing resource is saved.
302. Receiving a parking space inquiry request sent by a terminal, and determining parking space information of a target vehicle according to license plate information of the target vehicle carried by the parking space inquiry request;
after the parking space information of the target vehicle and the license plate information of the target vehicle are obtained, the parking space information and the license plate information can be stored in a database in an associated mode, and the parking space information and the license plate information can be conveniently obtained at any time.
When a terminal user needs to inquire the parking space for parking the vehicle, the license plate number of the vehicle is input into the terminal, the terminal generates a parking space inquiry request carrying the license plate number and sends the request to the information inquiry device, and the information inquiry device searches the parking space information of a target vehicle corresponding to the license plate number from the database according to the license plate number carried by the parking space inquiry request.
303. Returning the parking space information of the target vehicle to the terminal so that a user of the terminal determines the parking position of the target vehicle;
the operation performed in this step is similar to the operation performed in step 203 in the embodiment shown in fig. 2, and is not described again here.
In this embodiment, the description field is determined based on the preset data reporting mechanism, and the information query device identifies the description field based on the preset data reporting mechanism, so that the related information can be easily determined, and the scheme realizability is improved.
