[0028] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0029] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0030] The traffic condition sharing method, system, medium and device of the present invention are used to accurately, quickly and timely obtain real-time traffic conditions and share them.

[0031] like Figure 1a As shown, the road condition sharing method, system, medium and device of the present invention are applied to an application scenario constructed by a vehicle and a cloud processor. The vehicle sends first road condition information and first road condition photo information, and the cloud processor receives the first road condition information and first road condition photo information sent by the vehicle; identifies the first road condition photo information to obtain second road condition information; determines whether the first road condition information belongs to the second road condition information, and if so, obtains location information based on the first road condition photo information, and marks the corresponding location on the map based on the location information. In this way, real-time road condition information is shared with other vehicles for accurate, fast and timely acquisition of real-time road conditions and sharing.

[0032] like Figure 1b As shown, in one embodiment, the traffic condition sharing method of the present invention includes the following steps:

[0033] Step S11, receiving first road condition information and first road condition photo information sent by a vehicle.

[0034] Specifically, the vehicle obtains the first road condition photo information through a camera device when driving. The camera device can be installed in front of the vehicle, on the vehicle body, etc. The camera is used to take road condition photos to obtain the first road condition photo information.

[0035] Specifically, the first road condition photo information is obtained based on photographing the road ahead with a vehicle-mounted camera.

[0036] Specifically, the first road condition information acquisition includes:

[0037] Step S111: receiving voice information.

[0038] Specifically, when the vehicle is driving on the road, if the driver finds that there is a problem with the road condition, he will describe the road condition problem by recording, and send the recording information containing the description of the road condition problem to the cloud processor. The cloud processor receives the voice information.

[0039] Step S112: Convert the voice information into text information to obtain the first road condition information.

[0040] Specifically, the voice information is converted into text information based on a preset voice-to-text software. The voice-to-text software includes: Tencent Cloud Voice Recognition, Xunjie Text Assistant, iFlytek Hear, etc.

[0041] Step S12: Identify the first road condition photo information to obtain second road condition information.

[0042] Specifically, the identifying the first road condition photo information to obtain the second road condition information includes:

[0043] Step S121: Recognize the first road condition photo information based on a preset image recognition algorithm to obtain a recognition result.

[0044] Specifically, the image recognition algorithm includes: a convolutional neural network (CNN) algorithm and a feature extraction algorithm. Based on the preset image recognition algorithm, the road condition corresponding to the first road condition photo information can be obtained, thereby obtaining a recognition result. For example, a convolutional neural network model is trained with a standard road condition photo. After the convolutional neural network model is trained, the first road condition photo to be identified is put into the convolutional neural network model to obtain the corresponding recognition result.

[0045] Step S122: Convert the recognition result into text information to obtain second road condition information.

[0046] Step S13, determining whether the first road condition information belongs to the second road condition information, and if so, obtaining location information based on the first road condition photo information, and marking a corresponding location on a map based on the location information.

[0047] Specifically, the determining whether the first road condition information belongs to the second road condition information includes:

[0048] Step S131: Obtain a first traffic condition keyword based on the first traffic condition information.

[0049] Specifically, a road accident word library is preset, and a first road condition keyword is obtained from the first road condition information based on the road accident word library. Specifically, the first road condition information is segmented to obtain multiple words based on a preset Chinese text word segmentation algorithm, and the first road condition keyword is identified from the multiple words based on the preset road accident word library. The preset road accident word library is a pre-set word library containing vocabulary related to road accidents, and the first road condition information can be segmented to obtain multiple words, and the first road condition keyword is obtained by performing recognition on the preset road accident word library. The preset Chinese text word segmentation algorithm includes: reverse maximum matching method, Chinese sentence word segmentation algorithm (MaxMatch), etc.

[0050] Step S132, obtaining a second road condition keyword based on the second road condition information. A road section accident word library is preset, and a second road condition keyword is obtained from the second road condition information based on the road section accident word library. Specifically, the second road condition information is segmented to obtain a plurality of words based on a preset Chinese text segmentation algorithm, and the second road condition keyword is identified from the plurality of words based on the preset road section accident word library. The preset road section accident word library is a pre-set word library containing vocabulary associated with road section accidents, and the second road condition information can be segmented to obtain a plurality of words, which are identified through the preset road section accident word library to obtain the second road condition keyword. The preset Chinese text segmentation algorithm includes: reverse maximum matching method, Chinese sentence word segmentation algorithm (MaxMatch), etc.

[0051] Step S133, determining the similarity between the first traffic condition keyword and the second traffic condition keyword. Specifically, the similarity between the first traffic condition keyword and the second traffic condition keyword is compared based on a preset text similarity algorithm. For example, the text similarity algorithm is a semantic matching LSA (latent semantic analysis) type model, and the text topic matrix obtained by LSA can be used for text similarity calculation, and the calculation method is generally through cosine similarity.

[0052] Specifically, obtaining location information based on the first road condition photo information and marking a corresponding location on the map based on the location information include: the first road condition photo information includes the location information of the location when the first road condition photo was taken. Therefore, the location information can be obtained based on the first road condition photo information. After obtaining the location information, marking can be made on the corresponding location on the map according to the location information.

[0053] Specifically, marking the corresponding location on the map based on the location information includes: presetting the corresponding relationship between the road condition and the mark; judging the corresponding mark of the second road condition information based on the second road condition information and the corresponding relationship; and marking the corresponding location on the map. In this way, different marks can be set according to different road conditions, which is convenient for users to view and to identify different road conditions in a timely manner according to different marks.

[0054] Step S134: If the similarity is greater than a preset threshold, it is determined that the first road condition information belongs to the second road condition information.

[0055] Specifically, the following steps are also included:

[0056] Step S141: Acquire the second road condition photo information of the marked location sent by other vehicles.

[0057] Step S142: Identify the second road condition photo information to obtain third road condition information.

[0058] Step S143: determine whether the road condition is normal based on the third road condition information.

[0059] Step S144: when the traffic is normal, remove the mark of the location corresponding to the second road condition photo information on the map. In this way, it is possible to determine whether the traffic condition of the marked location has returned to normal based on the second road condition photo information of the marked location sent by other vehicles. If it has returned to normal, it can be updated in time to avoid misleading other users' travel.
