As shown in fig. 2, as a preferred embodiment of the present invention, the method further includes:
step S20: judging the regional partition environment data exceeding the update period based on the current latest regional partition environment data to obtain a judging result;
that is, the regional zone environmental data is continuously collected and uploaded by the vehicle, but needs to be updated; and is updated based on a set update period, so a new vehicle is required to upload;
step S21: identifying a target road section and/or a target position covered by the regional partition environmental data in the judging result;
when the updating period is exceeded and the updating is not performed, the target road section and/or the target position corresponding to the original regional partition environment data need to be identified, and the corresponding target road section and/or the target position is generally used as the marking data of the regional partition environment data, so that the covered target road section and/or the target position are easy to obtain;

when the driving direction coincides with at least one section of the target road section (all the target road section can be omitted or related data of the target road section can be collected), and/or the driving direction is positioned in a set distance range passing through at least one target position (the driving direction does not need to pass through the target position and only needs to reach the set distance range of the target position, because the data collecting device has a certain collecting range coverage), the driving direction coincides with the set distance range (all the target road section can be omitted) and a first vehicle corresponding to the driving direction can be obtained; or the first vehicle occupies a smaller volume, and the traffic capacity of the first vehicle is larger than that of the object to be passed;
step S24: sending an acquisition reporting request to a first vehicle to acquire updated environment data of a coverage target road section and/or a target position acquired by the first vehicle;
the acquisition and reporting request generally carries an acquisition and reporting visual angle, such as a parallel right-facing visual angle, a lowest definition, a format and the like, acquires updated environment data of a first vehicle acquired covering a target road section and/or a target position, and requires strict corresponding acquisition according to the target road section and/or the target position, so that the acquisition and reporting request also comprises a navigation route with a target road section and/or a target position mark;
step S25: and updating the regional partition environment data according to the updated environment data.
It can be understood that the regional partition environment data can be updated one by one according to the requirements of the target road section and/or the target position through a data updating mechanism of a preset period so as to meet the latest requirement that the regional partition environment data is up-to-date, thereby ensuring the accuracy of the traffic prompt information.
As a preferred embodiment of the invention, the first environmental data comprises video data and/or image data. The video data and/or image data is typically captured by an onboard camera and may also include a user's marking portion, as may the second environmental data.
As shown in fig. 3, as a preferred embodiment of the present invention, the method further includes:
step S30: identifying vehicles returning the first environmental data, generating a traffic prompt of the vehicles according to preset conditions to obtain the authorized times N, and marking the corresponding vehicles as second vehicles, wherein the preset conditions comprise updating the length of a target road section covered by the environmental data and the number of target positions; the preset target may further include a second vehicle; that is, when the second vehicle returns the first environmental data in the area, the next time the second vehicle is outside the area, the passing prompt of the vehicle can be obtained through the first request signal, and the authorization times of the passing prompt of the vehicle is related to the vehicle which returns the first environmental data; thus, the second environment data and the return do not need to be acquired outside the area;
namely, dividing the first environmental data according to preset conditions to obtain the number of times of acquisition authorization of the traffic prompt, for example, the length of each covered target road section is 5m, the number of times of acquisition authorization of the traffic prompt is +1, each covered target position is one, in the first environmental data, identifiers of corresponding target road sections exist, the target positions (such as parking spaces and the like) can be distinguished according to numbers, so that the first environmental data are directly counted, the total length of the covered target road sections and the total number of the target positions can be obtained, and then the total length and the total number are divided by the length of the target road sections and the number of the target positions authorized at a time to obtain the number of times of acquisition authorization of the traffic prompt N;
step S31: establishing a corresponding relation between a second vehicle and the pass prompt acquisition authorization times N, and storing the corresponding relation;
the corresponding relation between the second vehicle identification and the pass prompt acquisition authorization number N is generally adopted;
step S32: when a first request signal of an unknown vehicle is detected, judging whether the unknown vehicle is a second vehicle or not;
step S33: if so, sending the traffic prompt information to a second vehicle according to the first request signal, and subtracting 1 from the number of times N of obtaining the authorization of the traffic prompt, thereby obtaining the updated number of times of obtaining the authorization of the traffic prompt.
The number of times N of obtaining the authorization of the traffic prompt is reduced by 1 when the second vehicle obtains the traffic prompt information once, namely the number of times N of obtaining the authorization of the traffic prompt is consumed;
the number of grants is obtained based on the second vehicle update pass prompt. In addition, the number of times of obtaining the authorization by the traffic prompt and the consumption condition of the number of times of obtaining the authorization by the traffic prompt can be displayed on a central control screen of the second vehicle.
It should be understood that, by calculating the number of times the pass prompt obtains the authorization, the second vehicle returns the first environmental data in the area as follows: when the vehicle is outside the area next time, a passing prompt of the vehicle can be obtained through the first request signal, and the authorization times of the passing prompt of the vehicle is related to the vehicle which returns the first environment data; therefore, the traffic prompt can be obtained without collecting the second environmental data outside the area, and it is to be understood that the second vehicle is not subjected to the related calculation of the object to be passed at this time, so that the traffic prompt is generally the corresponding traffic prompt under the condition that the object to be passed is the largest, or the traffic prompts of the similar vehicle type closest to the second vehicle, or a plurality of traffic prompts are displayed for the user of the second vehicle to select, and in this case, the traffic prompt about the interior of the area can be obtained at the highest speed, so that whether the vehicle enters the interior of the area can be conveniently and comprehensively judged.

step S142: determining a second existing identifier and an obstacle in the regional partition environmental data;
in the regional partition environment data, including regional partition environment pictures, the second existing markers and barriers can be determined in the same way, the second existing markers are also existing markers which meet the preset similarity between the second existing markers and the regional partition environment pictures in the marker library, and the barriers are objects which do not appear in the marker library, such as branches, large stones, lost objects and the like which obstruct road sections; determining an obstacle, including confirming an approximate size of the obstacle in the same manner as in the previous step;
step S143: identifying the size relation between the first existing marker and the second existing marker, and determining the passing size of the obstacle-removing object in the area according to the size relation;
the actual size of the existing markers is known, and the size relationship comprises a size proportion relationship; the width or height (known) of the general access area that allows traffic without obstructions, such as the maximum width of the road segment; subtracting the height or the height occupied by the barrier from the width or the height of the allowed passage to obtain the passage size of removing the barrier in the area; the height or height occupied by the obstacle can be calculated in the last step; the above calculation is not difficult;
step S144: and selecting regional subarea environment sub-data with the passing size larger than the passing requirement size of the object to be passed. At this time, all the regional subarea environment data, including a plurality of regional subarea environment sub-data, are selected, wherein the passing size is larger than the passing requirement size of the object to be passed, namely, the requirement is met, and the object to be passed can smoothly pass without obstruction in the road section or the position of the regional subarea environment sub-data meeting the requirement.
By matching the regional zone environmental data according to the first mark and applying the relation between the known markers, the regional zone environmental data which is in theoretical compliance with the smooth passing size of the object to be passed and the road section and/or position corresponding to the regional zone environmental data are finally selected, so that reliable passing reference can be provided for the passing of the object to be passed.
