[0035] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0036] As mentioned above, if a large vehicle blocks the view while driving, it is difficult for the driver of the car behind to know important road condition information such as whether there is an intersection ahead, whether there are pedestrians crossing the road, the real-time status of the traffic light ahead, whether there is congestion ahead, etc. At this time, if the vehicle behind rashly changes lanes, overtakes, or accelerates without knowing the road conditions ahead, it is very easy to cause a traffic accident.

[0037] In order to solve the above problems, the present invention provides a road perspective method based on image sharing, a road perspective device based on image sharing, and a computer-readable storage medium, which can help drivers extend their line of sight based on road image sharing technology, so that drivers of following vehicles can see road conditions at a farther distance with the help of shared road images, thereby reducing and avoiding the occurrence of traffic accidents.

[0038] Please refer to Figure 1 , Figure 1 A schematic diagram of the architecture of a road perspective system provided according to some embodiments of the present invention is shown.

[0039] like Figure 1As shown, in some embodiments of the present invention, the road perspective system based on image sharing can be implemented based on the Internet of Vehicles technology, including the vehicle-mounted systems of multiple vehicles 11-13, the user mobile terminals 21-22 of multiple users, the road monitoring device 30 set on the road, and the cloud server 40 configured in the cloud. The vehicle-mounted monitoring device of the front vehicle 12-13 and the user mobile terminal 22 can collect the road condition image in front of the vehicle in real time as a sharing end of the road condition image. The road monitoring device 30 set in each area of ​​the road can collect the road condition image of the area in real time as a sharing end of the road condition image. The cloud server 40 is configured in the cloud of the Internet of Vehicles, which can serve as a transfer end of the road condition image and provide the road condition image uploaded by the sharing end to the receiving end in need. The driver of the rear vehicle 11 can use the vehicle-mounted system of the vehicle or the user mobile terminal 21 as the receiving end of the road condition image, and achieve the effect of road perspective by acquiring and displaying the road condition image in front.

[0040] The following will describe the above-mentioned road perspective method based on image sharing in conjunction with some embodiments in which the vehicle-mounted system of the rear vehicle 11 is used as a road perspective device. Figure 2 and Figure 3 , Figure 2 A schematic diagram of the architecture of a road perspective device based on image sharing provided according to some embodiments of the present invention is shown. Figure 3 A schematic flow chart of a road perspective method based on image sharing provided according to some embodiments of the present invention is shown.

[0041] like Figure 2 As shown, the above-mentioned road perspective device based on image sharing provided by the present invention may include a memory 111 and a processor 112. The memory 111 may include a computer-readable storage medium on which computer instructions are stored. The processor 112 is connected to the memory 111 and is suitable for executing the computer instructions stored on the memory 111 to implement a road perspective method based on image sharing. The road image sharing technology helps the driver extend his line of sight, so that the driver of the rear vehicle 11 can see the road conditions at a longer distance with the help of the shared road image, thereby reducing and avoiding the occurrence of traffic accidents.

[0042] like Figure 3 As shown, the road perspective method based on image sharing provided by the present invention may include step 301: determining the area to be perspective according to the perspective instruction input by the user.

[0043] In some embodiments of the present invention, the road perspective function can be activated in response to the user's operation of the vehicle system. Specifically, during the driving of the vehicle, the user can open the road perspective application by operating the central control system. The interface of the road perspective program may include a button for vehicle perspective mode. The user can click the vehicle perspective mode button to activate the vehicle perspective mode, so as to observe the traffic conditions such as the status of traffic lights, traffic flow, and pedestrian flow in the area blocked by the large vehicle 12 in front, so as to decide whether to change lanes, overtake, or accelerate.

[0044] In response to the user's selection of the vehicle perspective mode, the processor 112 may further require the user to input the number of vehicles to be perspective or the target perspective distance. Afterwards, the processor 112 may determine the area to be perspective based on the perspective instruction input by the user. In some embodiments, if the perspective instruction input by the user indicates the number of vehicles to be perspective, the processor 112 may use the vehicle network communication module to send the position information and the quantity information of the vehicle 11 to the cloud server 40, thereby determining the area to be perspective surrounded by the corresponding number of nearby vehicles through the cloud server 40, and determining all image capture devices in the area to be perspective. The vehicle network communication module here is preferably a 5G network communication module, which is used to improve the real-time performance of live broadcast of road conditions. The image capture device here includes but is not limited to the vehicle-mounted monitoring device of the front vehicles 12 to 13, the user mobile terminal 22 and the road monitoring device 30. The vehicle-mounted monitoring device may be a digital video recorder (DVR).

[0045] In other embodiments, if the perspective instruction input by the user indicates the target perspective distance, the processor 112 may first perform a threshold judgment on the target perspective distance input by the user to determine the method for determining the area to be perspective. Specifically, the distance threshold may be determined based on the maximum communication distance (e.g., 5 to 50 meters) of a near-field communication module such as a vehicle-mounted Bluetooth module. If the target perspective distance input by the user is less than or equal to the maximum communication distance of the vehicle-mounted Bluetooth module, the processor 112 may directly adjust the scanning distance of the vehicle-mounted Bluetooth module to the corresponding distance to determine the area to be perspective. Conversely, if the target perspective distance input by the user is greater than the maximum communication distance of the vehicle-mounted Bluetooth module, the processor 112 may use the vehicle-mounted network communication module to send the location information of the vehicle 11 and the target perspective distance to the cloud server 40, thereby determining the target perspective distance range as the area to be perspective through the cloud server 40, and determining all image capture devices within the area to be perspective.

[0046] like Figure 3 As shown, the road perspective method based on image sharing provided by the present invention may further include step 302: acquiring a road condition image of a corresponding area according to the area to be perspectived.

[0047] After determining the area to be viewed and all the image capturing devices therein, the processor 112 can determine the transmission channel of the road condition image according to the perspective instruction input by the user. In some embodiments, the processor 112 can perform a threshold judgment on the target perspective distance input by the user to determine the transmission channel of the road condition image. The distance threshold can be determined according to the maximum communication distance of the vehicle-mounted Bluetooth module. If the target perspective distance input by the user is less than or equal to the maximum communication distance of the vehicle-mounted Bluetooth module, the processor 112 can use a near-field communication module such as a vehicle-mounted Bluetooth module to search and connect all image capturing devices within the target perspective distance range to obtain all road condition images within the target perspective distance range. On the contrary, if the target perspective distance input by the user is greater than the maximum communication distance of the vehicle-mounted Bluetooth module, the processor 112 can use the vehicle-mounted network communication module to send the location information of the vehicle 11 and the target perspective distance to the cloud server 40, thereby obtaining all road condition images within the target perspective distance range from the cloud server 40.

[0048] Those skilled in the art will appreciate that the above-mentioned scheme of acquiring all road condition images within a long distance from the cloud server 40 is only a non-limiting implementation mode provided by the present invention, which is intended to clearly demonstrate the main concept of the present invention and provide some specific schemes that are convenient for the public to implement, rather than to limit the protection scope of the present invention. Optionally, in other embodiments, if the target perspective distance input by the user is greater than the maximum communication distance of the vehicle-mounted Bluetooth module, the processor 112 may first use the vehicle-mounted Bluetooth module to acquire all road condition images within its maximum communication distance range, and then use the vehicle-mounted network communication module to acquire all road condition images outside the maximum communication distance range of the vehicle-mounted Bluetooth module from the cloud server 40, so as to also obtain all road condition images within the target perspective distance range.

[0049] like Figure 3 As shown, the road perspective method based on image sharing provided by the present invention may further include step 303: filtering the acquired road condition images according to the perspective instruction.

[0050] As described above, the road condition images acquired by the vehicle system may include vehicle monitoring images, mobile terminal images, and road monitoring images acquired through network transmission channels and Bluetooth transmission channels. The processor 112 needs to filter these road condition images from various sources to determine the appropriate road condition images for display. In some embodiments of the present invention, the filtering of road condition images can be implemented with the help of a filtering module.

[0051] Please refer to Figure 4 , Figure 4 A schematic diagram showing the working principle of a screening module provided according to some embodiments of the present invention is shown.

[0052] like Figure 4 As shown, the above-mentioned screening module 113 can be a software module or a hardware module configured in the vehicle system. In the above-mentioned vehicle perspective mode, the processor 112 can control the vehicle-mounted monitoring device of the vehicle 11 to capture the road condition image in front of the vehicle 11 in real time. The screening module 113 can obtain the road condition image in front of the vehicle 11 in real time, and perform image recognition on the obtained road condition image to determine the license plate information of the vehicle 12 in front. Afterwards, the screening module 113 can filter the obtained vehicle-mounted monitoring image according to the recognized license plate information to filter and obtain the vehicle-mounted monitoring image captured by the vehicle 12 in front.

[0053] Optionally, in some embodiments, if the front vehicle 12 is not equipped with an on-board monitoring device or does not provide an on-board monitoring image, the screening module 113 can screen the acquired mobile terminal image according to the recognized license plate information to screen and obtain the mobile terminal image shot by the user mobile terminal 22 bound to the front vehicle 12. The mobile terminal image can be a shared image directly uploaded by the user mobile terminal 22 to the cloud server 40, or a live broadcast image obtained by the cloud server 40 from other network live broadcast platforms through an open network interface.

[0054] Optionally, in some embodiments, if the front vehicle 12 is not equipped with an onboard monitoring device or does not provide an onboard monitoring image, the processor 112 may also send the license plate information identified by the screening module 113 to the cloud server 40, so that the cloud server 40 determines the position of the front vehicle 12 and feeds back the identity information of the road monitoring device 30 at the corresponding position. The screening module 113 may screen the acquired road monitoring image according to the acquired identity information to screen and obtain the road monitoring image taken by the road monitoring device 30 at the corresponding position.

[0055] In some preferred embodiments, the processor 112 may also calculate the actual perspective distance of the vehicle-mounted monitoring image taken by the vehicle ahead according to the position information of the vehicle 11 and the position information of the vehicle ahead. If the perspective distance is less than the target perspective distance indicated by the perspective instruction input by the user, the processor 112 may control the screening module 113 to perform secondary recognition on the vehicle-mounted monitoring image taken by the vehicle ahead to obtain the license plate information of the vehicle ahead 13. Afterwards, the screening module 113 may perform secondary screening on the acquired vehicle-mounted monitoring image according to the license plate information of the vehicle ahead 13 to screen and obtain the vehicle-mounted monitoring image taken by the vehicle ahead 13.

[0056] It is understandable that, compared with the above mobile terminal images and the above road monitoring images, the vehicle monitoring images taken by the vehicle monitoring device are more in line with the driver's first-person perspective, and can give the driver of the rear vehicle 11 a visual experience of seeing through the front vehicle 12. Therefore, the vehicle monitoring image is more suitable as the preferred road condition image of the above vehicle perspective mode, which is conducive to improving the user experience.

[0057] like Figure 3 As shown, the road perspective method based on image sharing provided by the present invention may further include step 304: displaying the screened road condition image on the display of the vehicle 11 to perform perspective on the area to be perspectived.

[0058] After screening and obtaining the road condition image of the area to be viewed, the processor 112 can send the screened road condition image to the display 114 of the vehicle 11 to display the road condition image. The display 114 includes but is not limited to the central control display screen, the smart rearview mirror, and the user mobile terminal 21 such as a smart phone and a tablet computer bound to the vehicle 11. By displaying the road condition image taken by the front truck 12 on the display 114 of the vehicle 11, the driver of the rear vehicle 11 can clearly observe the road condition image in front of the front truck 12 as if he has viewed the front truck 12, thereby effectively reducing and avoiding the occurrence of traffic accidents.

[0059] In some embodiments, if the screening module 113 obtains multiple road condition images that meet the target perspective distance, the processor 112 can give priority to displaying the road condition images obtained through the near field communication module such as the vehicle-mounted Bluetooth module to the display 114 of the vehicle 11 to improve the real-time performance of the road perspective. In some embodiments, if the screening module 113 obtains multiple road condition images that meet the target perspective distance, the processor 112 can also give priority to displaying the road condition images with higher resolution to the display of the vehicle 11 to improve the clarity of the road perspective.

[0060] Those skilled in the art will appreciate that the above-mentioned vehicle perspective mode is only a non-limiting perspective mode provided by the present invention, which is intended to clearly demonstrate the main concept of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit the scope of protection of the present invention.

[0061] Optionally, in other embodiments, the interface of the road perspective program may further include a road congestion observation mode button. The user may click the vehicle perspective mode button in the navigation state to start the road condition observation mode, so as to observe the congestion condition of the road ahead.

[0062] Specifically, in response to the user's selection of the road condition observation mode, the processor 112 may further require the user to input a target perspective distance. The target perspective distance in the road condition observation mode may generally be 1 to 10 kilometers. Afterwards, the processor 112 may determine the position of the vehicle 11 after the target perspective distance along the navigation route as the target position of the area to be perspective based on the position information, navigation information, and target perspective distance input by the user of the vehicle 11. Thereafter, the processor 112 may use the vehicle network communication module to send the target position of the area to be perspective to the cloud server 40 to obtain the identity identification information of the road monitoring device 30 at the corresponding position from the cloud server 40. The screening module 113 may screen the acquired road monitoring images based on the acquired identity identification information to screen and obtain the road monitoring images taken by the road monitoring device 30 at the corresponding position.

[0063] Compared with the above-mentioned vehicle-mounted monitoring images and the above-mentioned mobile terminal images, the road monitoring images taken by the road monitoring device 30 have a higher, wider and more stable observation angle, which is more conducive to the driver's overall observation of the entire road section, so as to provide the driver with a reference for whether to change the navigation route. Especially in today's "Sky Eye" era, the road monitoring device 30 is spread across every corner of the city road, and can provide the driver with road condition images of any area without blind spots, so that the driver can clearly observe the road congestion conditions in any area on the navigation route.

[0064] In some preferred embodiments, for the scenario where the navigation program provides multiple optional routes, the processor 112 can also determine the position of the vehicle 11 after traveling the target perspective distance along each optional route as the target position of multiple areas to be perspective based on the position information of the vehicle 11, the navigation information of the multiple navigation routes, and the target perspective distance input by the user. Afterwards, the processor 112 can use the vehicle network communication module to send the target positions of the multiple areas to be perspective to the cloud server 40 to obtain the identity recognition information of the road monitoring device 30 at each corresponding position from the cloud server 40. The screening module 113 can screen the acquired road monitoring images according to the acquired identity recognition information to screen and obtain the road monitoring images taken by the road monitoring device 30 at each corresponding position.

[0065] After screening and obtaining the road monitoring images of each corresponding position, the processor 112 can display the road monitoring images of each target position on multiple displays of the vehicle 11 for split-screen display, or display the road monitoring images of each target position on multiple areas of the same display for partitioned display, so that the driver can simultaneously observe the road congestion conditions of each optional route to select a smoother navigation route.

[0066] Those skilled in the art will appreciate that the above-mentioned scheme of using the vehicle-mounted system of the vehicle 11 as a road perspective device is only some non-limiting implementation methods provided by the present invention, which is intended to clearly demonstrate the main concept of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit the protection scope of the present invention. Optionally, in other embodiments, the driver of the rear vehicle 11 can also use a user mobile terminal 21 such as a smart phone or a tablet computer as a road perspective device to achieve the same road perspective effect.

[0067] As described above, the road perspective method and road perspective device provided by the present invention need to be implemented based on the sharing of road condition images. Therefore, in some embodiments of the present invention, the processor 112 can also upload the vehicle-mounted monitoring image captured by the vehicle-mounted monitoring device of the vehicle 11, and / or the mobile terminal image captured by the user mobile terminal 21 bound to the vehicle 11 to the cloud server 40 in real time.
