Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
In order to improve the efficiency of image management operation, according to an aspect of the present invention, provide a kind of image storage method.This image storage method is particularly useful for the storage of great amount of images.Fig. 1 shows the indicative flowchart of image storage method 100 according to an embodiment of the invention.As shown in Figure 1, image storage method 100 comprises step S110, step S120 and step S130.
In step s 110, the Globally Unique Identifier of image is determined.Wherein, the Globally Unique Identifier of image is mapped to the memory address of image one to one.
Each image to be stored will be stored in unique memory address.This memory address can be disk address, also can be based on the address in the database of disk address foundation.Globally Unique Identifier is unique in whole storage system.Mapping relations one to one between Globally Unique Identifier and the memory address of image.
Particularly, step S110 can comprise: first, and the binary number that stochastic generation is 64, using the Globally Unique Identifier as image to be stored.Then, the man-to-man mapping between the memory address setting up this Globally Unique Identifier and this image to be stored.Note that the construction method of above-mentioned Globally Unique Identifier is only example object, not restriction of the present invention.Those skilled in the art also can utilize other means to build Globally Unique Identifier.
In the step s 120, set up and the multiple index of storage figure picture according to the satellite information of image to be stored.By this multiple index, GradeNDivision is carried out to whole image storage space, the efficiency of the bookkeepings such as image retrieval, analysis and display can have been significantly improved.
The satellite information of image can comprise the Globally Unique Identifier of determined image in above-mentioned steps S110.This Globally Unique Identifier can as the key assignments of above-mentioned multiple index.The satellite information of image can also comprise the user identifier of image collecting device.For an image storage system, it may need the image storing a lot of user.User can be identified according to the user identifier of its image collecting device.Such as, user can manage multiple image collecting device with same application (APP).So user can be logged in the user identifier of user name as the image collecting device of this user of this APP.The satellite information of image can also comprise image sources identifier.There is its oneself source in each image, such as specific image harvester.Image sources identifier can be the product ID of image collecting device.The satellite information of image can also comprise date of image capture.
The multiple index of image can be set up according to the satellite information of image.Wherein, each higher level's index corresponds to one or more subordinates index.Higher level's index and subordinate's index are two relative concepts.Its subordinate's index can be indexed by higher level's index.The image involved by image subordinate all with it index involved by higher level's index is completely the same.
At least there is higher level's index that corresponds to multiple subordinates index.Thus, the image corresponding to higher level's index can be allocated to different subordinate's indexes.In concrete example, the possible overwhelming majority even all higher level's index corresponds to multiple subordinates index.
Fig. 2 shows the schematic diagram of multiple index according to an embodiment of the invention.As shown in Figure 2, this multiple index comprises two-stage.In Fig. 2, uppermost form represents first order index, and three middle forms represent second level index.First order index relate to stored all images.Each second level index comprises a part of image.Nethermost cylinder represents the storage space of image, such as different server clusters.
In multiple index, each higher level's index comprises the value for determining adjacent subordinate index.For determining that the value of adjacent subordinate index is for being divided into corresponding adjacent subordinate index by the image involved by this higher level's index.Thus, whole multiple index becomes indivisible entirety.In concrete example, each higher level's index can be a concordance list, and this concordance list can comprise multiple row, and wherein the value of certain row is used for determining adjacent subordinate index.That is, according to the difference of the value in these row, the image of correspondence is divided into different adjacent subordinate indexes.
Still for the multiple index shown in Fig. 2, the value in last row of the first order index in Fig. 2 is the collection date of image, and it is for determining adjacent subordinate index.As shown in curve different in Fig. 2, gather the date be " 20141020 " image by be divided in the second level index shown in Fig. 2 leftmost that, gather the date be the image of " 20141021 " by that in the middle of being divided in the second level index shown in Fig. 2, gather the date be " 20141022 " image by be divided in the second level index shown in Fig. 2 rightmost that.
In multiple index, most subordinate index comprises the Globally Unique Identifier of image.In other words, Globally Unique Identifier is positioned at multiple index bottom, to set up the contact of the storage space of multiple index and image.
In the multiple index shown in Fig. 2, Globally Unique Identifier is the key assignments in this multiple index, and it is expressed with word " Key ".As shown in Figure 2, namely " Key " in the index of second level row store the Globally Unique Identifier of this multiple index, the storage space one_to_one corresponding of itself and image.
Below to set up the secondary index shown in Fig. 2, the detailed process setting up multiple index is described.For image to be stored, first obtain its satellite information, satellite information can comprise the collection date (Date) of the user identifier (Uid) of image collecting device, image sources identifier (Sn) and image.Then, the satellite information of image is added to first order index.When the satellite information of image is with when in storage system, the satellite information of conventional images is identical, in this step, no longer repeat to add to first order index.As shown in the first order index of Fig. 2, fourth line in first order index can represent that the user identification code image collecting device that to be the sequence number of the user of " 135 " be " daggsd " acquires image on October 22nd, 2014, and this image has been stored in storage system.Be appreciated that the data in every a line of first order index cannot indicate the number of corresponding image, only can represent the image existing in storage system and there is this satellite information.Such as, fourth line in first order index corresponds to three row data in the index of the rightmost second level.Finally, according to the collection date of image, the part satellite information of image and Globally Unique Identifier are added to corresponding second level index.Such as, the rightmost second level index shown in Fig. 2 is added to by gathering user identifier (Uid), image sources identifier (Sn) and the Globally Unique Identifier that the date is the image collecting device of the image of " 20141022 ".Because each Globally Unique Identifier is unique, so each provisional capital in the index of the second level corresponds to an image uniquely.Such as, in the index of the second level, that the first row rightmost represents that the image collecting device that the sequence number that user identification code is the user of " 135 " is " daggsd " has been stored into the storage space corresponding with Globally Unique Identifier " D " at the image that on October 22nd, 2014 gathers.Be appreciated that, the sequence number of user that user identification code is " 135 " is that the image collecting device of " daggsd " may acquire multiple image on October 22nd, 2014, these images have mutually different Globally Unique Identifier, as shown in three row data in rightmost second level index in Fig. 2.
In step s 130, which, the memory address of the image that Globally Unique Identifier image being stored into image maps.Here store operation to as if view data itself.
Image can be stored with dot matrix way.Dot matrix is the array of point, and the point in array can be called the pixel of image.Storage figure picture can also be carried out, the mode of such as vector with mathematical way.
In another one angle, image can be the image of various form, such as JPG form, BMP form etc.
In Fig. 2, nethermost cylinder represents the storage space of image, such as different server clusters.As shown in curve in figure, the image that " Key " value of second level index is respectively " A " and " C " is stored into corresponding address in first server cluster, the image being " B " by " Key " value of second level index is stored into corresponding address in second server cluster, and the image being " D " by " Key " value of second level index is stored into corresponding address in the 3rd server cluster.
Above-mentioned image storage method 100 shows the concrete execution sequence of step S110, step S120 and step S130.But one of ordinary skill in the art will appreciate that, shown execution sequence is only example, and unrestricted.Such as, step S130 can perform prior to step S120.Alternatively, step S130 can perform with step S120 simultaneously, to improve the execution speed of image storage method 100.
When retrieving the image stored based on above-mentioned image storage method 100, show, the bookkeeping such as deletion time, first, can go to retrieve most higher level's index, according to most its subordinate's index of higher level's indexed search.Similarly, retrieve step by step, until retrieve most subordinate index.Finally, the memory address of this image can be retrieved according to the Globally Unique Identifier of the image in most subordinate index, obtain this image.
Above-mentioned image storage method 100 make use of multiple index.At least one higher level's index can index multiple subordinates index, solves the problem of the bookkeeping inefficiencies such as image retrieval in prior art, display, deletion thus, correspondingly achieves the beneficial effect improving image management efficiency.
Alternatively, the multiple index setting up image in above-mentioned steps S120 may further include step S121, and first group of satellite information according to image sets up first order index.
This step S121 can specifically comprise: first, judges whether first group of satellite information of image repeats with first group of satellite information of the image in first order index.Then, for the situation not having to repeat, first of image group of satellite information is added in this first order index.So, avoid the row duplicated in first order index, ensure that its accuracy of first order index.
Step S120 can also comprise step S122, and second group of satellite information according to image sets up second level index.In this step, second of image group of satellite information is added in the index of the second level.Thus, the multiple index set up is secondary index.As mentioned above, Fig. 2 shows the schematic diagram of secondary index according to an embodiment of the invention.
On the one hand, the memory space brought of secondary index and calculated amount all less.On the other hand, because one-level index can correspond to a lot of secondary indexs.That is, the dimension of one-level index can be far longer than secondary index.So, both can manage all images easily by secondary index, improve the efficiency of management.
One of ordinary skill in the art will appreciate that, can also set up more than three grades indexes, it can support the store and management of greater amount image.But the burden that this stores bringing to storage system and calculating aspect is larger.
According to an example of the present invention, above-mentioned steps S121 sets up first order index and comprises further: the first satellite information according to image sets up first order index with the collection date.Wherein, the collection date of image is used for the image involved by first order index to be divided into second level index.Thus, involved in the index of each second level image is image gathered on the same day.Above-mentioned steps S122 sets up second level index and comprises further: set up second level index according to the first satellite information of image and Globally Unique Identifier.
According in the scheme of this example, according to the difference on the collection date of image, image is divided into different second level indexes.Secondary index as shown in Figure 2, first order index comprises three row.On the collection date that last row " Date " are image, as mentioned above, it is for determining the second level index of image.
The collection date of image is an important attribute of image.In the management system of the image of multi-user, user may propose the request such as retrieval and display about the image on particular acquisition date.Such as, for a kind of APP of the image information for monitoring ad-hoc location, it may have millions of users.The image that this APP utilizes image acquisition device a large amount of.For user, the image reviewing and retrieve a certain period may be expected.With the collection date Further Division image of image, can more convenient image management.
Secondary index as shown in Figure 2, above-mentioned first satellite information may further include user identifier (Uid) and/or the image sources identifier (Sn) of image collecting device.Both is also one of important attribute of image.When proposing the requests such as the retrieval of image and display as user, wishing can the result expected to user of fast return.The user identifier of image collecting device is the attribute relevant with user with image sources identifier, utilizes them, can navigate to the image that user expects more quickly.
Fig. 3 shows the indicative flowchart of image storage method 300 according to another embodiment of the present invention.As shown in Figure 3, this image storage method 300 comprises step S310, step S320, step S330 and step S340.Wherein, step S310, step S320 and step S330 are similar with the corresponding steps in above-mentioned image storage method 100 respectively, for simplicity, do not repeat them here.
In step s 320, set up and the multiple index of storage figure picture according to the satellite information of image.Wherein, the satellite information of image comprises the collection date of image.In step S340, delete the index of the image gathered at first and the image gathered at first according to the collection date of image, to discharge storage space.
The storage space of storage system is limited.How this limited storage space of Appropriate application is a major issue.For user, the user of the APP of the image information for monitoring ad-hoc location such as, above in example, recent image is normally more valuable.In this step S340, delete the image that gathers at first and its index according to the collection date of image, remain for prior image user, can while meeting consumers' demand, release storage space.
Be appreciated that in above-mentioned image storage method 100 and 200, can by subordinate's index stores of image in server cluster, this server cluster is different from the server cluster of the subordinate's index storing other images.Subordinate's index of image is multiple.Server cluster also can have multiple.By subordinate's index stores of different images in different server clusters, thus, more reasonably can utilize storage space.
For certain image to be stored, its memory address can be positioned at different server clusters from the memory address of other images.Again get back to Fig. 2, the user identifier Uid of image collecting device is " 123 ", image sources identifier Sn is " dddddc " and the image that key value Key is " A " is stored in first server cluster, image collecting device user identifier Uid is similarly " 123 ", image sources identifier Sn is " adadfs " and the image that key value Key is " B " is stored in second server cluster.Different images is stored in different server clusters by the support of above-mentioned image storage method 100 and 200, is effectively expanded the storage space of image by different server clusters.
