Detailed Description
Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the prior art, the storage mode of the picture information corresponding to the POI in the map is as follows: the picture data of the picture itself is stored in the cloud storage, and the picture related information (POI type information, POI related relationship, POI description information, and the like) is stored in the database. Therefore, the storage mode of the POI pictures in the current map is to be related to the POI, only relevant picture labels are added to store the POI pictures in the cloud, and then the cloud performs consistency check by using picture encryption check codes.
When a user views POI pictures, the user can only select all the pictures or view all the pictures according to labels, and the time of picture formation, the time situation and the change of picture formation can only be presumed according to the picture album.
The above scheme can complete the storage of POI associated pictures, but has the following disadvantages:
(1) The related information of the picture is stored in a database mode, the picture is not added with related information, and once the database information is changed, the picture is possibly inaccurate in description, and the information and the picture are inconsistent;
(2) The pictures are stored into the cloud storage, and once someone maliciously modifies or deletes data in the cloud storage, the information associated with the database is even still present, and the pictures are lost, so that the pictures are empty;
(3) When the information in the database is deleted, the related data in the cloud storage needs to be synchronously deleted. However, the scheme is easy to cause the condition that the picture in the cloud storage is not deleted, so that a large amount of redundant data is generated in the cloud storage.
Aiming at the problems, the embodiment of the application provides a method for processing the interest point picture, which can be used for solving the problems. The method of interest point image processing is described in detail below in several specific implementations.
Fig. 1 is an application scenario schematic diagram of a method for processing a picture of an interest point according to a first embodiment of the present application. As shown in fig. 1, the method for processing the point of interest picture provided in this embodiment is applied to a distributed storage system, where after generating a picture file according to the point of interest picture and the point of interest picture, slicing the picture file, and performing distributed storage on sliced data. When different interesting pictures are updated in different time periods aiming at the same interest point, the link address of the front picture can be added in each picture file, so that the time sequence chain of the interest point pictures can be established while the safety of the picture data is ensured.
In addition, the distributed database can be accessed through different terminal devices (such as a notebook computer, a personal computer and a smart phone), for example, the link address of the first slice data stored in the general database of the target picture file can be obtained by inputting identification information (such as the name of the interest point, the number of the interest point and other attribute information of the interest point) of the interest point, then the next slice data is sequentially obtained through a chain connection relation among the slice data until all the slice data are obtained, and then the complete interest point picture is displayed, so that the interest point picture can be effectively prevented from being tampered maliciously.
Fig. 2 is a flowchart of a method for processing a picture of a point of interest according to a second embodiment of the present application. As shown in fig. 2, the method for processing a picture of a point of interest provided in this embodiment includes:
step 101, receiving an acquisition request of the point of interest data.
Specifically, when the point of interest picture needs to be displayed, for example: the user may initiate a request for obtaining the point of interest data on the map when searching for a hotspot location such as a mall, a hospital, a parking lot, etc., where the request for obtaining may include identification information of the point of interest (for example, a name of the point of interest, a number of the point of interest, and other attribute information of the point of interest, etc.).
In one possible scenario, when the user needs to navigate to the parking lot a, the face map of the parking lot entrance may be displayed when the user is about to navigate to the parking lot entrance, and at this time, the identification information of the interest point in the acquisition request may be the name of the parking lot a.
In another possible scenario, when the user needs to find the B restaurant, the name of the B restaurant may be entered in the map, and an acquisition request for the point of interest data may be initiated to acquire a face map of the B restaurant.
Step 102, acquiring a target picture file according to the acquisition request.
In this step, a target picture file may be acquired according to the acquisition request, where the target picture file includes the point of interest picture and association information of the point of interest picture. It is to be appreciated that the point of interest picture may be a face view of the point of interest, and the associated information of the point of interest picture may be a capturing time of the face view of the point of interest.
It should be noted that, the related information of the point of interest picture may be stored in the point of interest picture to form the target picture file, and in addition, the related information of the point of interest picture may be stored in an additional database. And optionally, the related information of the interest point picture is encrypted and then stored in the interest point picture to form the target picture file.
And step 103, displaying the interest point picture and the associated information.
In this step, after the target picture file is acquired according to the acquisition request, the point-of-interest picture and the associated information may be displayed. Specifically, the face map corresponding to the point of interest and the time taken by the face map may be displayed at a designated position on the map, for example, the face map of the parking lot a and the time taken by the face map are displayed below the map, or the face map of the restaurant B and the time taken by the face map are displayed below the map.
In this embodiment, by receiving an acquisition request of the point of interest data, and then acquiring a corresponding target picture file according to the identification information of the point of interest in the acquisition request, where the target picture file includes the point of interest picture and the associated information of the point of interest picture, when the acquired point of interest picture and the associated information of the point of interest picture are displayed, since the target picture file itself carries the associated information, the problem that the point of interest picture does not coincide with the associated information of the picture when the information is displayed due to the change of external information is avoided.
On the basis of the above embodiment, fig. 3 is a schematic flow chart of a method for processing a point of interest picture according to a third embodiment of the present application. As shown in fig. 3, the method for processing a picture of an interest point provided in this embodiment may further include:
step 201, receiving an update request of the point of interest data.
Specifically, an update request of the point of interest data is received, wherein the update request includes the point of interest update picture and update association information of the point of interest update picture.
For example, for the face map currently stored in restaurant B, which is photographed in month 2017, 6, the face may change significantly due to the longer time the restaurant B may be refitted. At this time, the server may accept and receive an update request for the B restaurant, and the update request includes the B restaurant update picture and update related information of the B restaurant update picture, which may be, for example, a face image taken in 3 months in 2019.
The updating request of the interest point data is received, and the updating picture file is generated according to the interest point updating picture and the updating association information in the updating request, so that the data of the same interest point can be updated in a staged mode, and the map user can acquire the latest picture information.
And 202, updating the picture according to the interest points and generating an updated picture file according to the updated associated information.
Optionally, after generating the updated picture file according to the point of interest updated picture and the update association information, a forward link and a backward link may also be generated. Specifically, the backward link is used for connecting the current updated picture file to the picture file updated last time, and the updated picture file includes the backward link. For example, the B-restaurant picture file corresponding to month 2019 and 3 includes a forward link for linking the B-restaurant picture file corresponding to month 2019 and 3 to the B-restaurant picture file corresponding to month 2017 and 6, and the B-restaurant picture file corresponding to month 2017 and 6 includes a backward link for linking the B-restaurant picture file corresponding to month 2017 and 6 to the B-restaurant picture file corresponding to month 2019 and 3.
Fig. 5 is a schematic diagram of a picture file data link structure according to a fifth embodiment of the present application, and fig. 7 is a schematic diagram of displaying a point of interest picture and associated information according to the embodiment shown in fig. 5. As shown in fig. 5 and 7, 3 picture files (e.g., face view 1, face view 2, and face view 3) are corresponding to one interest point, wherein the face view 1, the face view 2, and the face view 3 may be arranged according to the generated time sequence. The back link SH11 is included in the face figure 1, and the back link SH11 is used to link the face figure 1 to the face figure 2. The front link SH01 and the back link SH21 are included in the face fig. 2, wherein the front link SH01 is used to link the face fig. 2 to the face fig. 1, and the back link SH21 is used to link the face fig. 2 to the face fig. 3. Further, the front link SH11 and the rear link SH31 are included in the face map 3, wherein the front link SH11 is used to link the face map 3 to the face map 2, and the rear link SH31 is used to link the face map 2 to the next face map.
By generating the forward link and the backward link, a chain structure between the picture files is established according to the time sequence, and the picture files have time sequence relations because the picture files record the front picture file and the rear picture file, the time information of the attached picture of the POI can be effectively displayed according to the time sequence relations, and when all the picture files of one POI can be stored in the mode, the historical change of one POI can be effectively and reasonably displayed.
In addition, after generating the updated picture file, the updated picture file may be further subjected to slicing processing to form a data slice set, wherein a plurality of data slices are sequentially arranged in the data slice set, and a first link for connecting the first data slice to a previous data slice and a second link for connecting the first data slice to a second data slice are generated for the first data slice, wherein the second data slice is a next data slice of the first data slice in the data slice set.
With continued reference to fig. 5, for the face fig. 1, the data slicing operation may be performed on the face fig. 1, for example, may be divided into 5 data slices (data slice 1, data slice 2, data slice 3, data slice 4, and data slice 5), while a first link SH01 and a second link SH02 are generated for the data slice 1, and SH02 and SH03 are allocated for the data slice 2, where SH02 is used to link the data slice 1 and the data slice 2. SH03 and SH04 are assigned to data slice 3, wherein SH03 is used to link data slice 2 with data slice 3. SH04 and SH05 are assigned to the data slice 4, wherein SH04 is used to link the data slice 3 with the data slice 4. Whereas if the data slice 5 is the last data slice, it need only be allocated SH05 for linking forward to the data slice 4.
And, the backward link of the face fig. 1 may be set to SH11 of the first data fragment in the face fig. 2, so that the face fig. 2 may be acquired through the face fig. 1 and SH11, while the forward link set in the face fig. 2 may be SH01 of the first data fragment in the face fig. 1, so that the face fig. 1 may be acquired through the face fig. 2 and SH01, and the forward link set in the face fig. 2 may be SH21 of the first data fragment in the face fig. 3, so that the face fig. 3 may be acquired through the face fig. 2 and SH 21.
And the image file is subjected to slicing processing to form a data slice set, and the chained connection relation of each data slice is established by storing the linked form of the last data slice and the next data slice in each data slice, so that each data slice can be sequentially acquired to generate the image of the interest point and display the image.
In addition, after the first link and the second link are generated for the first data slice, a first link hash value may be generated according to the first link and a preset hash algorithm, and a second link hash value may be generated according to the second link and the preset hash algorithm, where the first data slice includes the first link hash value and the second link hash value, and the second data slice includes the second link hash value.
That is, for the face fig. 1, a first link hash value SH01 and a second link hash value SH02 are generated for the data slice 1, and SH02 and SH03 are allocated to the data slice 2, wherein SH02 is used to link the data slice 1 and the data slice 2. SH03 and SH04 are assigned to data slice 3, wherein SH03 is used to link data slice 2 with data slice 3. SH04 and SH05 are assigned to the data slice 4, wherein SH04 is used to link the data slice 3 with the data slice 4. Whereas if the data slice 5 is the last data slice, it need only be allocated SH05 for linking forward to the data slice 4.
By encrypting the links to generate link hash values, the pictures can be generated again according to all slice data only after all the slice data hash values of the pictures corresponding to the interest points are collected, so that the pictures of the interest points are prevented from being tampered maliciously.
Further, FIG. 6 is a schematic diagram of the encrypted database data storage structure of the embodiment shown in FIG. 5. As shown in fig. 5-6, each data slice in the set of data slices may also be stored in a plurality of different link addresses, and the mapping relationship between the link address and the corresponding link hash value for each data slice may be stored in the encrypted database, and the first link hash value may be stored in the general database, where the first data slice is the first data slice in the set of data slices and the first link is the backward link.
By storing each data slice in the set of data slices into a plurality of different link addresses, a distributed multi-storage of all data slices is achieved, and the actual link address of the data slice corresponding to the link hash value is also recorded into the distributed encrypted database. However, because the related information storage records only one mapping relationship, there is no other meaning, and if there is no correct decryption mode and data slice integration mode, the corresponding interest point picture cannot be restored and processed.
In addition, the picture link address in the universal database is only the link hash value of the first slice data corresponding to the picture slice data, and the interest point picture can be generated again according to the full slice data only after the slice hash values of the corresponding pictures are completely collected, so that the interest point picture is ensured not to be tampered maliciously.
Moreover, as the picture files record the front and back picture files, the picture files have a time sequence relationship, and according to the time sequence relationship, the time information of the attached picture of the POI can be effectively displayed, and when all the picture files of one POI can be stored in the mode, the historical change of one POI can be effectively and reasonably displayed.
And if the data of the picture corresponding to the interest point of the POI is modified, but if the hash information corresponding to the picture is not modified, the historical condition of the picture can be restored according to the time sequence information contained in the picture file, because the related associated information is already stored in the picture file and is not strongly dependent on other databases.
In other words, because the POI picture itself can encrypt and record relevant important associated information of a picture part, the picture can be prevented from being damaged to the greatest extent under the condition that the database is abnormal, in addition, if network attack occurs, a user can not restore the picture by only using part of the picture slices, meanwhile, because the slices are stored in a distributed mode, only one place has data fluctuation, the picture can be restored by other regional storage, and the situation of losing the POI picture can not occur. In addition, because the POI picture has a chain structure, when redundancy occurs in the data, the whole data can be pulled out for processing through chain change of the picture, and the redundancy of the picture is effectively reduced.
Fig. 4 is a flowchart of a method for processing a picture of a point of interest according to a fourth embodiment of the present application. As shown in fig. 4, the method for processing a picture of an interest point provided in this embodiment includes:
Step 301, receiving a request for acquiring the point of interest data.
Specifically, when the point of interest picture needs to be displayed, for example: the user may initiate a request for obtaining the point of interest data on the map when searching for a hotspot location such as a mall, a hospital, a parking lot, etc., where the request for obtaining may include identification information of the point of interest (for example, a name of the point of interest, a number of the point of interest, and other attribute information of the point of interest, etc.).
In one possible scenario, when the user needs to navigate to the parking lot a, the face map of the parking lot entrance may be displayed when the user is about to navigate to the parking lot entrance, and at this time, the identification information of the interest point in the acquisition request may be the name of the parking lot a.
In another possible scenario, when the user needs to find the B restaurant, the name of the B restaurant may be entered in the map, and an acquisition request for the point of interest data may be initiated to acquire a face map of the B restaurant.
Step 302, obtaining a first link hash value according to the identification information of the interest point.
Step 303, obtaining a first link address of the first data slice according to the first link hash value.
Step 304, a first data slice is acquired according to the first link address.
Step 305, obtaining a second link address of the second data slice according to the second link hash value in the first data slice.
Step 306, obtaining a second data slice according to the second link address.
Step 307, generating a target picture file according to the acquired data slice set.
Step 308, displaying the point of interest picture and the associated information.
The picture link address existing in the general database is only the link hash value of the first slice data corresponding to the picture slice data, and after the acquisition request of the interest point data is acquired, the first link hash value can be acquired according to the identification information of the interest point, that is, the link hash value of the first slice data of the slice data is acquired first. Then, since the POI pictures and each slice data in the same POI picture have a chain structure, the subsequent data slices can be obtained at one time according to the link hash value of the first slice data, and the point-of-interest picture is generated according to the whole slice data after the slice hash values of the corresponding pictures are all collected.
