Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0032] The specific implementation of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0033] Figure 1 A schematic diagram of an underground garage electronic map drawing system based on the Internet of Vehicles in one embodiment of the present application is shown. Figure 1 As shown, the system may include: a plurality of vehicle-mounted terminals 11 and a map maintenance device 12 .

[0034] The map maintenance device 12 may send a task to a plurality of vehicle terminals 11 , and the task may be an underground garage mapping task.

[0035] Each vehicle terminal 11 is equipped with a display screen, through which tasks sent by the map maintenance device 12 can be displayed, for example, underground garage mapping tasks can be displayed.

[0036] When the vehicle terminal 11 displays a task, it also displays a first control and a second control corresponding to the task, and in response to the first control being selected, the vehicle terminal 11 accepts the task. In response to the second control being selected, the vehicle terminal 11 abandons the task.

[0037] When the task is a garage drawing task and the first control corresponding to the garage drawing task is selected, the vehicle-mounted terminal 11 starts to monitor the position of the vehicle, wherein the vehicle is a vehicle equipped with the vehicle-mounted terminal 11 .

[0038] How the vehicle-mounted terminal 11 monitors the position of the vehicle is not described here. Figure 2 A corresponding embodiment of a method for drawing an electronic map of an underground garage based on the Internet of Vehicles.

[0039] After the vehicle terminal 11 detects that the vehicle has entered the underground garage corresponding to the underground garage drawing task, it sends first certification information to the map maintenance device 12, where the first certification information is used to prove that the vehicle has entered the underground garage indicated by the underground garage drawing task.

[0040] After receiving the first certification information, the map maintenance device 12 verifies the first certification information to determine whether the vehicle enters the underground garage. After the verification is passed, a data collection instruction can be sent to the vehicle terminal 11.

[0041] After receiving the data collection instruction sent by the map maintenance device 12, the vehicle terminal 11 collects and stores the monitoring data obtained by the steering sensor, speed sensor and gyroscope configured on the vehicle to monitor the vehicle respectively.

[0042] Afterwards, after detecting that the vehicle has left the underground garage, the vehicle-mounted terminal 11 may send the monitoring data and the second certification information to the map maintenance device 12. The second certification information is used to indicate that the vehicle has left the underground garage.

[0043] After the map maintenance device 12 verifies the second certification information, it draws an electronic map of the underground garage based on the monitoring data.

[0044] The network is used as a medium to provide a communication link between each vehicle terminal 11 and the map maintenance device 12, and may be a wired network or a wireless network.

[0045] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPSec) and the like may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may also be used to replace or supplement the above-mentioned data communication technologies.

[0046] The vehicle-mounted terminal 11 may be any electronic device, including but not limited to a smart phone, a vehicle computer, etc.

[0047] The map maintenance device 12 may be a server that provides various services, such as a background management server that provides support for the device operated by the user using the vehicle terminal 11. The background management server may analyze and process the received request data, and feed back the processing results to the terminal device.

[0048] Optionally, the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0049] Those skilled in the art will know that Figure 1 The number of vehicle-mounted terminals in the embodiment is only for illustration, and any number of terminal devices, networks and servers may be provided according to actual needs. This embodiment of the present application does not limit this.

[0050] Under the above system architecture, an embodiment of the present application provides a method for drawing an electronic map of an underground garage based on the Internet of Vehicles, which can be executed by any electronic device with computing and processing capabilities. For example, the electronic device is a vehicle-mounted terminal.

[0051] Figure 2 A flowchart of a method for drawing an electronic map of an underground garage based on the Internet of Vehicles in an embodiment of the present application is shown. Figure 2 As shown, the method for drawing an electronic map of an underground garage based on the Internet of Vehicles provided in an embodiment of the present application includes the following S201 to S204.

[0052] S201, in response to receiving an underground garage mapping task sent by a map maintenance device, detecting a location of a vehicle.

[0053] Among them, the vehicle-mounted terminal is configured on the vehicle.

[0054] After the map maintenance device issues the underground garage drawing task, the display screen configured by the vehicle terminal can display the underground garage drawing task and display the first control and the second control. If the first control is selected, the vehicle terminal receives the underground garage drawing task, and if the second control is selected, the vehicle terminal abandons the underground garage drawing task.

[0055] After receiving the underground garage mapping task, the vehicle terminal starts to monitor the location of the vehicle. The embodiment of the present application does not limit how the vehicle terminal monitors the location of the vehicle. For example, the vehicle terminal can be configured with a positioning function to monitor the location information of the vehicle terminal, and the location of the vehicle can be determined based on the location information of the vehicle terminal.

[0056] S202, after detecting that the vehicle enters the underground garage, first certification information is sent to the map maintenance device, so that after the map maintenance device verifies the first certification information, it sends a data collection instruction to the vehicle terminal.

[0057] The embodiments of the present application do not limit how to determine whether a vehicle enters an underground garage.

[0058] In one embodiment, the underground garage mapping task includes the area range of the underground garage. When the positioning information of the vehicle-mounted terminal indicates that the vehicle-mounted terminal enters the area range, it is determined that the vehicle enters the underground garage.

[0059] In another embodiment, the underground garage mapping task includes the area range of the underground garage, and the vehicle-mounted terminal has a positioning function. The process of the vehicle-mounted terminal determining that the vehicle enters the underground garage may include: obtaining positioning information of the vehicle-mounted terminal according to the positioning function; after determining the area range of the vehicle entering the underground garage according to the positioning information, obtaining the posture data monitored by the gyroscope and the speed data monitored by the speed sensor; when the posture data indicates that the vehicle is traveling downhill and the speed data indicates that the vehicle is traveling downhill and exceeds a first distance threshold, determining that the vehicle enters the underground garage.

[0060] Using speed data, posture data and positioning information to jointly determine the way a vehicle enters an underground garage can make the judgment result more accurate.

[0061] The embodiment of the present application does not limit the specific value of the first distance threshold, and it can be set according to experience. For example, the first distance threshold is 15 meters, or 20 meters, etc.

[0062] In one embodiment, the vehicle is equipped with a camera, and the vehicle terminal is equipped with a positioning function. When the vehicle terminal detects that the vehicle enters the underground garage, before sending the first certification information to the map maintenance device, the method further includes: obtaining a target image including the entrance of the underground garage and a target timestamp of the target image through the camera; obtaining the positioning information of the vehicle terminal according to the positioning function; and generating the first certification information including the target image, the target timestamp and the positioning information.

[0063] The embodiments of the present application do not limit how to obtain a target image including the entrance of the underground garage by using a photographing device.

[0064] In one embodiment, after receiving the image captured by the camera, the vehicle-mounted terminal recognizes the image, and after recognizing that the image includes the following garage entrance, the image is used as the target image.

[0065] In one embodiment, the vehicle terminal is configured with a target recognition model for identifying whether an image includes an underground garage entrance. For example, the model may be any CNN (Convolutional Neural Network), such as VGG (Visual Geometry Group), ResNet (Residual Network), etc. The vehicle terminal may use the target recognition model to recognize the image captured by the camera, and when recognizing that a certain image includes an underground garage entrance, determine that the certain image is a target image.

[0066] In one embodiment, after the vehicle terminal determines the area where the vehicle enters the underground garage based on the positioning information, it uses the target recognition model to recognize the image captured by the shooting device.

[0067] After the vehicle enters the area of ​​the underground garage, the image recognition is started to obtain the target image, which can reduce the waste of computing resources and energy of the vehicle terminal.

[0068] In one embodiment, when the image captured by the camera is uploaded to the vehicle terminal, the timestamp when the image is captured is also uploaded. After the vehicle terminal determines that any image captured by the camera is a target image, the timestamp uploaded with the image is used as the target timestamp.

[0069] By configuring the first proof information including the target image, the target timestamp and the positioning information, it is possible to better determine that the vehicle has entered the underground garage corresponding to the underground garage drawing task, which is conducive to determining that the vehicle has entered the underground garage according to the task requirements, and further conducive to accurately drawing the electronic map of the underground garage.

[0070] After the vehicle-mounted terminal generates the first certification information, it sends the first certification information to the map maintenance device. After the map maintenance device verifies the first certification information, it sends a data collection instruction to the vehicle-mounted terminal.

[0071] The embodiments of the present application do not limit how the map maintenance device verifies the first certification information.

[0072] For example, the map maintenance device stores an entrance image of an underground garage corresponding to the underground garage drawing task. The map maintenance device calculates the similarity between the target image and the entrance image, and when the similarity between the target image and the entrance image exceeds a similarity threshold, determines that the target image includes the entrance of the underground garage.

[0073] The embodiment of the present application does not limit the specific value of the similarity threshold, and it can be set based on experience. For example, the similarity threshold is 0.95, or 0.98, etc.

[0074] Afterwards, the map maintenance device calculates the time difference between the target timestamp and the time when the first certification information is sent, and determines the size relationship between the time difference and the time difference threshold. If the time difference is less than the time difference threshold, the target timestamp verification is passed.

[0075] The embodiment of the present application does not limit the specific value of the time difference threshold, and it can be set according to experience. For example, the time difference threshold is 1 second, or 5 seconds, etc.

[0076] The map maintenance device determines whether the location indicated by the positioning information in the first certification information is within the area of ​​the underground garage. If the location is within the area of ​​the underground garage, the positioning information verification is passed. Otherwise, if the location is outside the area of ​​the underground garage, the positioning information verification is failed.

[0077] When the target image, target timestamp and positioning information are all verified, it means that the first certification information is verified. After that, the map maintenance device sends a data collection instruction to the vehicle terminal.

[0078] S203, in response to receiving the data collection instruction, collecting and storing monitoring data obtained by the steering sensor, the speed sensor and the gyroscope respectively monitoring the vehicle.

[0079] After receiving the data collection instruction, the vehicle terminal obtains the authentication to send the monitoring data to the map maintenance device, and can send the monitoring data to the map maintenance device.

[0080] The monitoring data includes: steering data obtained by a steering sensor when monitoring the vehicle, speed data obtained by a speed sensor when monitoring the vehicle, and posture data obtained by a gyroscope when monitoring the vehicle.

[0081] S204, after detecting that the vehicle has left the underground garage, sending second certification information and monitoring data to the map maintenance device, so that after the map maintenance device verifies the second certification information, it can draw an electronic map of the underground garage according to the monitoring data.

[0082] The vehicle-mounted terminal continuously collects and stores monitoring data, and continuously detects whether the vehicle has left the underground garage. The embodiments of the present application do not limit how to detect whether the vehicle has left the underground garage.

[0083] For example, the vehicle-mounted terminal has a positioning function, through which the positioning information of the vehicle-mounted terminal itself can be obtained. After determining the area where the vehicle leaves the underground garage based on the positioning information, it is determined that the vehicle leaves the underground garage.

[0084] In another embodiment, the vehicle is further equipped with a camera, which can capture images. When it is detected that the image includes an exit of the underground garage, it can be determined that the vehicle has left the underground garage.

[0085] In one embodiment, before sending the second proof information and monitoring data to the map maintenance device, the second proof information needs to be generated first. The process of generating the second proof information may include: obtaining the positioning information of the vehicle terminal according to the positioning function; generating the second proof information including the positioning information.

[0086] Afterwards, the vehicle terminal sends the second certification information and monitoring data to the map maintenance device. The second certification information can indicate that the vehicle has left the underground garage, and further indicates that the monitoring data includes the entire process from the vehicle entering the underground garage to leaving the underground garage, which is conducive to drawing a complete and accurate electronic map of the underground garage.

[0087] After receiving the second certification information and the monitoring data, the map maintenance device first verifies the second certification information. The embodiments of the present application do not limit how the map maintenance device verifies the second certification information.

[0088] For example, the map maintenance device verifies whether the location indicated by the positioning information included in the second certification information is outside the area of ​​the underground garage. When the location indicated by the positioning information is outside the area of ​​the underground garage, it is determined that the second certification information is verified.

[0089] After the second certification information is verified, the map maintenance device draws an electronic map of the underground garage based on the monitoring data.

[0090] By using the vehicle's posture data, speed data, and steering data, the vehicle's driving trajectory can be calculated through integration to obtain an electronic map of the underground garage.

[0091] In the technical solution provided in the embodiments of the present application, the on-board terminal collects and stores monitoring data obtained by the steering sensor, speed sensor and gyroscope configured on the vehicle, and sends the data to the map maintenance device, which generates an electronic map of the underground garage based on the detection data. This method does not require the use of satellite positioning, but is based on inertial navigation data (including data measured by the gyroscope and speed sensor) and steering data to accurately calculate the vehicle's driving trajectory, thereby realizing the accurate drawing of the electronic map of the underground garage.

[0092] Furthermore, by using the map maintenance equipment to publish tasks and the on-board terminal to accept tasks, any vehicle equipped with a steering sensor, a speed sensor and a gyroscope can perform the underground garage drawing task, thereby improving the parallelism of drawing electronic maps of each underground garage, thereby improving the efficiency of drawing electronic maps of multiple underground garages.

[0093] Furthermore, the vehicle-mounted terminal sends the first proof information and the second proof information to the map maintenance device. After the map maintenance device verifies the first proof information and the second proof information respectively, it instructs data collection and draws an electronic map of the underground garage based on the monitoring data. This can ensure the accuracy and high quality of the monitoring data to a certain extent, thereby ensuring the accuracy of the drawn electronic map.

[0094] In some embodiments, the map maintenance device maintains an account corresponding to the vehicle-mounted terminal. After completing the drawing of the electronic map of the underground garage, the map maintenance device can increase the resource value on the account by a certain value to reward the vehicle-mounted terminal for completing the underground garage drawing task, which is conducive to getting more vehicle-mounted terminals to participate in completing the underground garage drawing task, and then facilitating the faster completion of the drawing of multiple underground garage electronic maps.

[0095] Afterwards, the map maintenance device may send a task completion notification to the vehicle terminal, where the task completion notification includes a resource value reward corresponding to the underground garage drawing task, and the resource value reward is added to the resource value of the account by the map maintenance device.

[0096] The vehicle-mounted terminal receives the task completion notification sent by the map maintenance device, and completes the underground garage mapping task.

[0097] Based on the same inventive concept, the embodiment of the present application also provides an electronic map drawing device for underground garages based on the Internet of Vehicles, as shown in the following embodiment.
