Optionally, the real-time road condition image may be an image of a road surface condition of a road on which the vehicle is currently driving, the real-time position may be specific position information of the road on which the vehicle is currently located, and the real-time road condition features may be features representing a state of the real-time road condition image, for example, the real-time road condition features may include features of congestion of the road, smoothness of the road, mud of the road, water logging of the road, road collapse, and the like, the vehicle may summarize features that do not affect normal driving of the vehicle into normal road condition features, such as features of smoothness of the road, and the like, and summarize features that may affect normal driving of the vehicle into risky road condition features, such as features of congestion of the road, roughness of the road, mud of the road, water logging of the road, road collapse, and the like.

In specific implementation, after acquiring a plurality of real-time road condition images, the vehicle camera can perform image recognition on the real-time road condition images, and extract real-time road condition features of the real-time road condition images by adopting a machine vision technology.

Specifically, the image recognition can be performed by inputting the real-time road condition image collected by the vehicle-mounted camera into the image processing model to capture the characteristics of the image. The machine vision technology is based on a bionic angle, a machine replaces human eyes to measure and judge, for example, the simulation eyes acquire images through a vision sensor (such as a vehicle-mounted camera), and image processing and recognition are carried out by an image processing system after acquisition, the machine vision technology can be divided into a monocular vision technology, a binocular vision technology and a multi-ocular vision technology, wherein the monocular vision technology refers to the fact that one vision sensor can complete vision tasks such as positioning and the like.

As an example, in the running process of a vehicle on a road, the vehicle-mounted camera acquires a real-time road condition image a, a real-time road condition image B and a real-time road condition image C in real time, and a real-time position a corresponding to the real-time road condition image a, a real-time position B corresponding to the real-time road condition image B and a real-time position C corresponding to the real-time road condition image C, and respectively performs image recognition on the real-time road condition image a, the real-time road condition image B and the real-time road condition image C, and extracts that the real-time road condition feature of the real-time road condition image a is that the road is flat, the real-time road condition feature of the real-time road condition image B is that the road is muddy, and the real-time feature of the real-time road condition image C is that the road is collapsed by adopting a monocular vision technology and a binocular vision technology.

in the embodiment of the invention, if the vehicle detects that the communication connection is established between the vehicle and the sharing system corresponding to the road surface to which the real-time position of the image acquired by the vehicle-mounted camera belongs, the vehicle can send the target road condition image to the sharing system (the information base end and the road surface end), thereby realizing the information sharing between the vehicle and the sharing system.

Alternatively, the sharing system may be a system for sharing information with a vehicle to ensure that the vehicle can acquire the traveling road information in real time and quickly, and may include an information base end and a road surface end, where the information base end may be a terminal arranged in a certain area and used for processing the received road condition information, and is generally arranged in an area where road condition damage easily occurs. The road surface end can be a port arranged in each road, in the process of actually arranging the road surface end, the number of the road surface ends needs to be ensured to cover more roads as far as possible, and if the total coverage cannot be ensured due to factors such as environmental limitation, the road with higher danger probability can be arranged when the vehicle runs.

In specific implementation, if it is detected that communication connection is established between the vehicle and the sharing system corresponding to the road surface to which the real-time position belongs, the target position corresponding to the target road condition image is acquired, the target road condition image and the target position are packaged, and the target road condition image and the target position are sent to the information base end corresponding to the road surface to which the real-time position belongs.

Specifically, after the vehicle is in communication connection with the information base, the target road condition image and the target position may be packaged into one or more packages.

Step 104, receiving a current road condition risk score sent by the road end, wherein the current road condition risk score is a score aiming at the target road condition image and obtained after risk calculation is carried out on the target road condition image by the road end;

in the embodiment of the invention, the current road condition risk score is a score aiming at a target road condition image obtained after the road surface end receives the target road condition image sent by a vehicle and carries out risk calculation on the target road condition image, and after the vehicle sends the target road condition image to the road surface end, the road surface end can return the current road condition risk score to the vehicle.

And 105, receiving reminding information aiming at the target road condition image, which is sent by the road side, if the current road condition risk score is greater than or equal to a preset threshold value.

In the embodiment of the invention, if the current road condition risk score is greater than or equal to the preset threshold, the reminding information aiming at the target road condition image sent by the road side is received, and if the current road condition risk score is less than the preset threshold, the vehicle does not process or respond to the target road condition image and keeps running normally.

Optionally, the preset threshold may be a value set in advance by a relevant technician according to an actual demand, for example, the preset threshold may be 70 minutes, 80 minutes, 90 minutes, and the like, and the reminding information may be information sent by a road end for reminding a current road condition when the current road condition risk score is greater than or equal to the preset threshold, for example, the reminding information may be "a road in a position 50 meters ahead is muddy, and please drive cautiously. "," the road collapsed 100 m ahead, please stop driving or detour. The vehicle receiving the reminding information may be a vehicle currently sending the target road condition image, an adjacent vehicle, or a cloud server, which is not limited in this respect.

As an example, referring to fig. 2, a flow chart of steps for processing a real-time road condition image between a vehicle and a sharing system is shown, assuming that a real-time road condition image a, a real-time road condition image B, a real-time road condition image C, a real-time position a corresponding to the real-time road condition image a, a real-time position B corresponding to the real-time road condition image B, and a real-time position C corresponding to the real-time road condition image C are collected by a vehicle-mounted camera in real time during the driving of the vehicle, a preset threshold value is 70 minutes, and image recognition is respectively performed on the real-time road condition image a, the real-time road condition image B, and the real-time road condition image C, and a monocular vision technology and a binocular vision technology are adopted to extract that the real-time road condition feature of the real-time road condition image a is flat, the real-time road condition feature of the real-time road condition image B is smooth, and the real-time road condition feature of the real-time road condition image C is a landslide, taking the real-time road condition image C as a target road condition image, detecting that a vehicle establishes communication connection with a sharing system corresponding to a road surface to which the real-time position C belongs, acquiring a target position corresponding to the target road condition image, packaging the target road condition image and the target position, sending the target road condition image and the target position to an information base end corresponding to the road surface to which the real-time position belongs, updating data of the information base end based on the target road condition image, carrying out risk calculation on the target road condition image by the road surface end to obtain a current road condition risk score for the target road condition image, wherein the current road condition risk score is greater than a preset threshold value, and receiving reminding information sent by the road surface end for the target road condition image: "there is a road collapse on the road at present, please go round the road. ".

In an embodiment of the invention, a vehicle uploads a target road condition image acquired in real time to an information base, the information base can update the road condition, when the vehicle needs to acquire the road condition information of a road ahead in the driving process, an information acquisition request can be sent to an information base end according to a preset time period, and then a current road condition image corresponding to the information acquisition request is acquired from the information base end, and the vehicle can acquire reminding information corresponding to the current road condition image, so that a driver can actively plan a corresponding driving route, or a vehicle with an automatic driving function can automatically plan a corresponding driving route.

Meanwhile, in order to ensure the timeliness of obtaining the road condition of the vehicle in the driving process, the time period of the current road condition image can be requested from the information base end, the current road condition image and the position information exceeding the preset time period are cleared, and invalid information is prevented from occupying a storage space.

Referring to fig. 3, a flowchart of steps of another method for prompting a road surface condition provided in the embodiment of the present invention is shown, and is applied to a sharing system, where the sharing system includes an information base end and a road surface end, and specifically includes the following steps:

step 301, if it is detected that a communication connection is established between a sharing system corresponding to a road surface to which a real-time position belongs and a vehicle, receiving a target road condition image sent by the vehicle by the information base;

in the embodiment of the invention, the sharing system can process the road condition information, and receive, store, update, transmit and the like, if the sharing system detects that the information base end corresponding to the road surface to which the real-time position belongs is in communication connection with the vehicle, the information base end receives the target road condition image sent by the vehicle.

Optionally, referring to fig. 4, a schematic diagram of communication between the collection node and the sharing system is shown, where a vehicle-mounted camera of the vehicle is the collection node, a road surface end in the sharing system is used as an intermediate station (processor) for processing road surface conditions, an information base end is used as a connection node arranged in each place, the vehicle may store a private key of the vehicle-mounted camera in an information base of the information base end in advance, the information base end may share the private key base with the road surface end, and the sharing system may send road condition information and road danger level assessment to a relevant road processing department.

As an example, the information base end may synchronize a target road condition image acquired by a vehicle in real time, if it is detected that a communication connection is established between the sharing system corresponding to the road surface to which the real-time position belongs and the vehicle, the information base end receives the target road condition image sent by the vehicle, the target road condition image is a package of the target road condition image and the target position by the vehicle, and the target road condition image is sent to the information base end corresponding to the road surface to which the real-time position belongs, if the current road condition image exists at the information base end, the target road condition image is updated to be the current road condition image, and if the current road condition image does not exist at the information base end, the target road condition image is stored to the information base end as the current road condition image.

As another example, the vehicle may select to share information with other nearby vehicles, and after the vehicle acquires the target road condition image through the vehicle-mounted camera, the target road condition image may be transmitted to the other vehicles through the wireless network, so as to implement a road surface condition sharing function.

In an example of the present invention, the information base terminal may send the current road condition image to the vehicle, and when receiving an information acquisition request sent by the vehicle in a preset time period, the information base terminal sends the current road condition image corresponding to the information acquisition request in the information base to the vehicle.

Step 302, the road surface end performs risk calculation on a target road condition image sent by the vehicle to obtain a current road condition risk score corresponding to the road surface;

in the embodiment of the invention, the road surface end can carry out risk calculation on the target road condition image sent by the vehicle to obtain the current road condition risk score corresponding to the road surface.

Optionally, the road surface end may be configured with an information receiving device and an information processing device, so as to receive and process the road condition information sent by the vehicle, analyze the dangerous degree of the road surface condition, and prompt corresponding personnel or departments to maintain and process the road in time.

In the specific implementation, the pavement end receives a private key, a target road condition image and a real-time position sent by a vehicle, the road surface to which the real-time position belongs corresponds to a preset risk coefficient, the pavement end carries out risk calculation on risk road condition characteristics according to the preset risk coefficient, obtains a current road condition risk score corresponding to the road surface, and sends the current road condition risk score to the vehicle.

In particular, private key encryption algorithms use a single private key to encrypt and decrypt data, which must be protected from unauthorized agents since any party with the key can use to decrypt the data, private key encryption is also known as symmetric encryption because the same key is used for both encryption and decryption. Private key cryptographic algorithms are very fast (compared to public key algorithms) and are particularly suitable for performing cryptographic transformations on large data streams. Typically, a private key algorithm (called a block cipher) is used to encrypt one block of data at a time.

As an example, referring to fig. 5, a schematic diagram of an information base end searching for road condition information through a private key is shown, when a vehicle-mounted camera uploads the road condition information to the information base end for the first time, the private key and a serial number thereof need to be uploaded together, a user can select whether to connect the vehicle-mounted camera to a network, if the vehicle-mounted camera connects and uploads the vehicle-mounted camera, after the information base end checks the serial number compliance of the vehicle-mounted camera, the private key is added into a private key base of the user, information transmitted from the private key is received subsequently, the private key can be retrieved from the private key base, and a source of the information is trusted, after the vehicle-mounted camera adds the private key into the private key base, the user can obtain and request a shared information base through information carrying position information, and request the latest information of surrounding road conditions to the information base end.

Step 303, if the current road condition risk score is greater than or equal to a preset threshold, generating a prompting message for the target road condition image, and sending the prompting message and the current road condition risk score to the vehicle.
