As described above, with the continuous development of basic technologies such as satellite positioning, internet of vehicles, and road calculation algorithms, accuracy and instantaneity of vehicle navigation have been improved. However, existing vehicle navigation schemes are generally required to be implemented based on high-speed, stable satellite signals and network signals. Once a vehicle enters a mountain area, a grassland, a desert, a tunnel, a bridge bottom and other areas with poor satellite signals or network signals, key information such as traffic states, road states, traffic accidents and the like in front or around cannot be obtained in real time, so that the accuracy and the instantaneity of vehicle navigation are affected.

In order to overcome the defects in the prior art, the invention provides two methods for processing shared information, a system for processing shared information and a computer readable storage medium, key information around a vehicle can be acquired through a vehicle-mounted camera, and real-time sharing of the key information around the vehicle is realized through inter-vehicle radio wave communication, so that reliability, accuracy and real-time performance of vehicle navigation are improved.

In some non-limiting embodiments, the method for processing shared information provided in the first aspect and/or the second aspect of the present invention may be implemented via the shared information processing system provided in the third aspect of the present invention. Specifically, the processing system is configured with a memory and a processor. The memory includes, but is not limited to, the above-described computer-readable storage medium provided in the fourth aspect of the present invention, having stored thereon computer instructions. The processor is coupled to the memory and configured to execute computer instructions stored thereon to implement the method of processing shared information as provided in the first and/or second aspects of the present invention.

Referring first to fig. 1, fig. 1 is a flow chart illustrating a method for processing shared information according to some embodiments of the present invention.

As shown in fig. 1, in the process of collecting and outputting shared information, the shared information processing device configured on the first vehicle may collect surrounding images in all directions of front, rear, left, right, etc. of the first vehicle through the camera of the vehicle recorder, the reverse image, and the 360 ° panoramic image system, and record the collecting position and collecting time of each image.

In some embodiments, the operation of capturing the image may be manually triggered based on control instructions provided by a user. Specifically, the processing device may acquire touch, click, and voice control instructions provided by a user via a human-computer interaction interface such as a touch button, a mechanical button, a knob, and a microphone that are in the vehicle, and acquire at least one image around the first vehicle according to the acquired control instructions.

Further, in some embodiments, the operation of capturing images may be automatically implemented based on an artificial intelligence model of machine vision. In particular, the processing device may continuously and indiscriminately acquire a plurality of images around the host vehicle at various stages of the first vehicle traveling, temporary stop, and the like. The processing device may then identify and filter at least one image with preset content therein based on the pre-constructed and trained artificial intelligence model of machine vision, and determine a category for each image based on one or more preset content in each image. The solution of the artificial intelligence model of machine vision constructed and trained is not related to the technical improvement of the present invention and will not be described herein.

Further, in some embodiments, the preset content may be selected from at least one of traffic state, road state, traffic accident, and event. For example, the processing device may recognize the number and/or the density of vehicles around the host vehicle, in particular in front of the host vehicle, from the acquired at least one image. If the identification result indicates that the number of vehicles in the acquisition area is smaller than or equal to the first number threshold value n, the processing device can determine that the images indicate traffic states of unobstructed road conditions. If the identification result indicates that the number of vehicles in the acquisition area is greater than the first number threshold n and less than the second number threshold m, the processing device can determine that the images indicate traffic states of the creep road conditions. If the identification result indicates that the number of vehicles in the collection area is greater than or equal to a second number threshold m, the processing device can determine that the images indicate traffic states of the congested road conditions. For another example, the processing device may identify whether there are conditions of road falling stones, road cracks, road depressions, road flooding, road traffic restriction, road construction, and the like around the host vehicle according to the acquired at least one image. If the identification result indicates that at least one of road falling stones, road cracks, road depressions, road flooding, road traffic limitation and road construction exists in the acquisition area, the processing device can determine that the images indicate corresponding road states. For another example, the processing device may identify whether there is a scratch, a damage, an injury, or the like of the vehicle around the host vehicle according to the at least one acquired image. If the identification result indicates that at least one of vehicle scratch, vehicle damage and personal injury exists in the acquisition area, the processing device can determine that the images indicate corresponding traffic accidents. For another example, the processing device may identify whether a situation such as a festoon, a walk, a festival celebration, a road show, a guard vehicle team, etc. exists around the host vehicle according to the at least one acquired image. If the identification result indicates that at least one of a festoon, a walk, a festival celebration, a road director and a guard car team exists in the acquisition area, the processing device can determine that the images indicate corresponding activity events.

Then, in response to identifying and screening out the image with any one or more preset contents, the processing device may store the image with any one or more preset contents to the shared information set or memory of the corresponding category as shown in table 1 for later step invocation.

TABLE 1

Category(s)	Time	Position of	Data type
				Traffic state	T1	P1{x1,y1,z1}	Frame data
Road condition	T2	P2{x2,y2,z2}	Frame data
				Traffic accident	T3	P3{x3,y3,z3}	Frame data
Event of activity	T4	P4{x4,y4,z4}	Frame data
				Special 1 (private)	T5	P5{x5,y5,z5}	Text of
Special 2 (help seeking)	T6	P6{x6,y6,z6}	Text, sound, etc

Furthermore, in the embodiment shown in table 1, the processing device may be further preferably configured with an information category of the private information and/or the recourse information for storing the private information and/or recourse information transmitted to the outside of the host vehicle (i.e., the first vehicle).

As shown in fig. 1, after capturing an image and determining the type of the image, the processing device may perform approximate screening on the captured multiple images according to the type, the capturing position and the capturing time to screen out the image similar to at least one existing image captured by the host vehicle (i.e. the first vehicle) and/or the external vehicle (i.e. the at least one third vehicle), so as to avoid the bidirectional burden of the sender and the receiver caused by repeated transmission of the same or similar data.

Specifically, the processing device may first read category information, acquisition position information, and acquisition time information of the existing image. Here, the existing image includes, but is not limited to, at least one image acquired in advance of the host vehicle (i.e., the first vehicle), and/or at least one image acquired in advance by at least one external vehicle (i.e., the third vehicle). The processing device may read, from a local memory of the host vehicle (i.e., the first vehicle), category information, acquisition location information, and acquisition time information of an existing image acquired in advance by the first vehicle. In addition, the processing device may further read, from a local memory of the host vehicle (i.e., the first vehicle), the category information, the acquisition position information, and the acquisition time information of the pre-received existing image pre-acquired by the at least one third vehicle. In addition, the processing device can also directly acquire the category information, the acquisition position information and the acquisition time information of the pre-acquired existing image from at least one external vehicle (namely a third vehicle) in real time.

The processing means may then compare the acquired images with these existing images. In response to the acquired image and any existing image belonging to the same category, the distance d between the first acquisition position and the second acquisition position of the existing image is smaller than a preset first distance threshold d _th And the time difference delta t between the first acquisition time and the second acquisition time of the existing image is smaller than the preset duration threshold delta t _th The processing device can determine that the acquired image approximates the existing image and screen out the acquired image.

Further, in some embodiments, the first distance threshold d _th A preset duration threshold Δt _th May preferably be set individually according to the category of the captured image. For example, the first distance threshold d is set for the traffic state information _th May be set to 100 meters with a preset duration threshold deltat _th May be set to 30 seconds. For another example, the first distance threshold d is set for the traffic accident information _th May be set to 10 meters with a preset duration threshold deltat _th May be set to 60 seconds.

As shown in table 2, if the acquired image and the existing image indicate the same content (i.e. belong to the same category), the processing device can determine that the acquired image approximates to the existing image and screen out the acquired image if the distance d= |p2-p1| <100m between the first acquisition position P1 and the second acquisition position P2 of the existing image and the time difference Δt= |t2-t1| <30s between the first acquisition time T1 and the second acquisition time T2 of the existing image. Therefore, the invention can accurately judge whether the content is approximate according to the content characteristics corresponding to each type of picture, thereby further avoiding the repeated transmission of the same or approximate data and reducing the bidirectional burden of a sender and a receiver.

TABLE 2

As shown in fig. 1, after capturing the image and determining the image category, the processing device may determine shared information from the content of the approximately screened image and transmit the shared information to the second vehicle via radio waves.

In some embodiments, the shared information includes, but is not limited to, an image collected by the host vehicle, text information corresponding to the content of the image, and/or a sound signal corresponding to the content of the image. The processing device may determine the corresponding transmission carrier frequency according to the type of the acquired image as shown in table 3, and then input the transmission carrier frequency to the modulator of the radio wave transmission module shown in fig. 2, and the modulator performs modulation synthesis of the shared information in the form of image, text and/or voice according to the transmission carrier frequency. The processing device may amplify the modulated shared information via a high frequency amplifier, and transmit the shared information via the vehicle antenna to a frequency band of the transmission carrier frequency, so as to transmit the shared information via the frequency band of the transmission carrier frequency to an external second vehicle.

TABLE 3 Table 3

Further, in the embodiment shown in table 3, the processing device may further acquire and store disclosure authority information of each acquired image and/or a transmission distance of the host vehicle (i.e., the first vehicle) to the external second vehicle. Then, the processing device can comprehensively determine the transmission carrier frequency of the shared information according to the category of the image and the public authority information and/or the transmission distance of the image. For example, a transmission carrier frequency with a lower frequency but a weaker penetration capability is configured for the help seeking shared information with a longer transmission distance, and a transmission carrier frequency with a higher frequency but a stronger penetration capability is configured for the shared information such as traffic state, road state, traffic accident, activity event, etc. with a shorter transmission distance. For another example, a carrier frequency of a transmission of a specific frequency is configured for encrypted shared information of a point-to-point transmission.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a determination of a frequency band occupation according to some embodiments of the present invention.

As shown in fig. 3, in some embodiments of the present invention, considering that a plurality of vehicles employing the present invention may transmit shared information on the same frequency band at the same time, the processing apparatus may preferentially determine whether the corresponding frequency band f2 is occupied before transmitting the shared information (e.g., road state information such as a front construction). If the judging result indicates that the message being sent exists on the frequency band f2, the processing device can judge that the frequency band f2 is occupied, so that the message is confirmed again after waiting for the first waiting time T-retry millisecond, and the message is cycled back and forth until the message of the current frequency band f2 is sent completely (i.e. the frequency band f2 is recovered to an unoccupied state), or the number of times of confirmation reaches a preset number of times threshold M, or the vehicle (i.e. the first vehicle) has driven out of a preset second distance threshold L-max. In response to the number of acknowledgements reaching the preset number of times threshold M, or the host vehicle (i.e. the first vehicle) has driven out of the preset second distance threshold L-max, the processing means may determine that the shared information to be transmitted has not been time-efficient, thereby discarding the transmission.

Otherwise, if the above determination result indicates that there is no message being sent on the frequency band f2, the processing device may determine that the frequency band f2 is unoccupied. At this time, in order to separate the shared information to be transmitted from the previous message, the processing apparatus may wait for the second waiting time T-int0 ms before transmitting the shared information to the frequency band f2 of the carrier frequency. In addition, in some embodiments, the processing device may further repeat transmission of the shared information to the frequency band f2 of the transmission carrier frequency at intervals according to the third waiting time T-int1, so as to ensure that the shared information can be reliably sent and received.

Referring further to fig. 4, fig. 4 is a schematic diagram illustrating the elimination of shared information crosstalk provided according to some embodiments of the present invention.

As shown in fig. 4, if a plurality of vehicles near the site acquire the same image almost simultaneously, and almost simultaneously confirm that no data is being transmitted in the corresponding frequency band f2, the processing devices disposed on the respective vehicles determine that the respective vehicles can transmit the shared information, so that after waiting for the second waiting time T-int0 ms, the respective local shared information is transmitted to the corresponding frequency band f2, respectively, and data crosstalk in which a plurality of shared signals are superimposed is generated in the frequency band. For this reason, in some embodiments of the present invention, the processing device may immediately acquire real-time feedback information from the frequency band f2 after completing the operation of transmitting the shared information to the corresponding frequency band f2, and compare the real-time feedback information with the transmitted shared information to verify whether there is data crosstalk on the frequency band f 2.

In response to the comparison result that the real-time feedback information is consistent with the shared information, the processing device may determine that there is no data crosstalk on the frequency band f2, so as to repeatedly transmit the shared information of the preset number of times N to the frequency band f2 of the transmission carrier frequency at intervals according to the third waiting time T-int1 as described above.

Otherwise, in response to the comparison result that the real-time feedback information is inconsistent with the shared information, the processing device may determine that there is data crosstalk on the frequency band f2, so as to generate a random fourth waiting time T-rdm0 in the range of M to N, and after waiting for T-rdm ms, retransmit the shared information to the frequency band f2, and retrieve the real-time feedback information from the frequency band f2 to re-compare. At this time, if the acquired real-time feedback information is inconsistent with the shared information, the processing device may determine that there is still data crosstalk on the frequency band f2, so as to repeat the operations of random waiting, retransmission of the shared information, re-acquisition of the real-time feedback information, and re-comparison until the acquired real-time feedback information is consistent with the shared information. Thus, the invention can lead a plurality of senders to be separated. When a party (e.g. car a) transmits after T-rdm ms, a following transmitter (e.g. car B) acquires and confirms that there is already existing information on the frequency band f2 that is similar to or duplicate to the shared information to be transmitted by itself, the processing device configured in car B can cancel the related transmission operation, so as to avoid data crosstalk formed by the multiparty shared information on the transmission carrier frequency f2, avoid repeated transmission of the same or similar data, and avoid bidirectional burden of the transmitter and the receiver caused by the same or similar data.

Please refer to fig. 5 and fig. 6 in combination. Fig. 5 is a flow chart illustrating a method for processing shared information according to some embodiments of the present invention. Fig. 6 illustrates a schematic diagram of a radio wave processing system provided in accordance with some embodiments of the invention.

As shown in fig. 5 and 6, in the process of receiving and processing the shared information, the shared information processing apparatus disposed on the first vehicle may acquire the shared information transmitted by the external vehicle via the radio wave via the antenna.

Specifically, the processing device may scan the bands f1 to f6 of each preset transmission carrier frequency one by one at intervals of a preset interval time T-rev ms as shown in table 3, so as to determine whether the bands f1 to f6 where each transmission carrier frequency is located have shared information to be received. In response to a judging result that the shared information to be received exists in any frequency band, the processing device can acquire the shared information and input the shared information into the demodulator at the rear end, so that the demodulator determines the information category to which the shared information belongs according to the transmission frequency band of the shared information and/or analyzes the shared information to determine the corresponding information category, the acquisition position and the acquisition time. As described above, the information category is determined by analyzing the content of the image collected by the transmitting end (i.e., the external vehicle) of the shared information, and is selected from at least one of traffic state, road state, traffic accident, and event. The traffic state may be selected from at least one of a clear road condition, a slow road condition, and a congested road condition. The road condition may be selected from at least one of road drop, road crack, road pit, road flooding, road traffic limitation, road construction. The traffic accident may be selected from at least one of vehicle scratch, vehicle damage, personal injury, and death. The event is selected from at least one of a festive train, a parade, a festival celebration, a road director, and a guard fleet.

Then, the processing device can perform approximate screening on the acquired shared information according to the type, the acquisition position and the acquisition time of the acquired shared information so as to further screen shared information similar to the local existing information, and sort and temporarily store the approximately screened shared information into a corresponding cache according to the type of the shared information.

Specifically, as described above, in performing the approximate screening, the processing device may first read category information, acquisition location information, and acquisition time information of the existing information. Here, the existing image includes, but is not limited to, at least one image acquired in advance of the host vehicle (i.e., the first vehicle), and/or at least one image acquired in advance by at least one external vehicle (i.e., the third vehicle). The processing device may read, from a local memory of the host vehicle (i.e., the first vehicle), category information, acquisition location information, and acquisition time information of an existing image acquired in advance by the first vehicle. In addition, the processing device may further read, from a local memory of the host vehicle (i.e., the first vehicle), the category information, the acquisition position information, and the acquisition time information of the pre-received existing image pre-acquired by the at least one third vehicle. In addition, the processing device can also directly acquire the category information, the acquisition position information and the acquisition time information of the pre-acquired existing image from at least one external vehicle (namely a third vehicle) in real time.

Thereafter, the processing apparatus may compare each shared information acquired via radio waves with these existing information. In response to the acquired shared information and any existing information belonging to the same category, the distance d between the first acquisition position and the second acquisition position of the existing image is smaller than a preset first distance threshold d _th And the time difference delta t between the first acquisition time and the second acquisition time of the existing image is smaller than the preset duration threshold delta t _th The processing device can determine that the shared information is similar to the existing information and screen out the shared information.

Further, in some embodiments, the first distance threshold d _th A preset duration threshold Δt _th May preferably be set individually according to the category of the shared information. For example, traffic status messages as described aboveInformation about the first distance threshold d _th May be set to 100 meters with a preset duration threshold deltat _th May be set to 30 seconds. For another example, the first distance threshold d is set for the traffic accident information _th May be set to 10 meters with a preset duration threshold deltat _th May be set to 60 seconds.

As shown in table 2, if the obtained shared information and the existing information indicate the same content (i.e. belong to the same category), the processing device can determine that the shared information is similar to the existing information and screen out the shared information if the distance d= |p2—p1| <100m between the first acquisition position P1 and the second acquisition position P2 of the existing image and the time difference Δt= |t2-t1| <30s between the first acquisition time T1 and the second acquisition time T2 of the existing image. Therefore, the invention can accurately judge whether the content is approximate according to the content characteristics corresponding to each kind of information, thereby further avoiding the repeated transmission of the same or approximate data and further reducing the burden of a receiver.

Further, in some embodiments, the shared information includes, but is not limited to, an image captured by an external vehicle, text information corresponding to the content of the image, and/or a sound signal corresponding to the content of the image. After the approximately screened shared information is acquired, the processing device can sort and temporarily store the approximately screened text information and/or sound signals into corresponding caches according to the category of the shared information, and additionally store the approximately screened image data according to indexes.

Then, as shown in fig. 2, the processing device may further perform corresponding processing on the shared information subjected to the approximate screening according to the information category. For example, please refer to fig. 7. FIG. 7 illustrates a schematic diagram of a shared information display interface provided in accordance with some embodiments of the invention.

In the embodiment shown in fig. 7, in response to the collision of the vehicle collected by the second vehicle in front of the vehicle and transmitted via radio waves, and the shared information that the road section in front is in the creep road condition, the processing device configured in the vehicle may determine the corresponding traffic accident category icon (e.g. five-pointed star) and the creep icon (e.g. bold arrow) according to the category of the shared information. Then, the processing device can determine the corresponding coordinates P (x 1, y1, z 1) of each icon on the navigation map according to the acquisition positions of the shared information, and uses the accident point P (x 1, y1, z 1) as the center to mark five stars and match with a continuous flashing display mode, and then the corresponding category icons are displayed by tracing and thickening a certain lane area around the point P (x 1, y1, z 1). Here, the received image and/or text information may be displayed at a default zoom scale beside, may be displayed in an enlarged scale, or may be hidden to avoid interference with the navigation interface. In addition, the processing device can also automatically play the text-converted content through the default selected voice, or directly play the received and obtained sound signal through the audio player of the vehicle (namely, the first vehicle).

Therefore, even if the vehicle enters a mountain area, a grassland, a desert, a tunnel, a bridge bottom and other areas with poor satellite signals or network signals, the vehicle-mounted wireless communication system can still collect key information around the vehicle through the vehicle-mounted camera, and realize real-time sharing of the key information around the vehicle through inter-vehicle radio wave communication, so that a user is reliably, accurately and real-time reminded of rescheduling a driving path, and congestion is avoided in time.
