Detailed Description

The present application provides a file searching method, a device, a storage medium and a mobile terminal, so that the purposes, technical schemes and technical effects of the present application are more clear and clarified, and the following further describes the present application in detail, and it should be understood that the specific embodiments described herein are only for explaining the present application and are not intended to limit the present application.

Referring to fig. 1, fig. 1 is a flow chart of a file searching method provided in an embodiment of the present application, which is applied to a mobile terminal, and the specific flow of the file searching method may be as follows:

s101: and acquiring a file searching instruction, wherein the file searching instruction carries the first target characteristic information.

Specifically, when the user needs to search for a picture or video file stored in the mobile terminal, the user may enter a file search interface (as shown in fig. 2) of the mobile terminal, and may input the first target feature information in the file search interface, and then the mobile terminal may receive a file search instruction triggered by an input operation of the user on the first target feature information. The first target feature information may be a keyword or a template file, when the first target feature information is a keyword, the keyword may be a type name of a shot object in a picture or a video file that a user needs to search, for example, "person", "animal", "landscape", "building" or "food", and when the first target feature information is a template file, the template file may be a template video (for example, a video that a shooting subject is a child) or a template picture (for example, a baby face picture).

S102: determining a first target electric signal corresponding to the first target characteristic information, and determining a positioning electric signal corresponding to each stored file in the mobile terminal according to the file searching instruction, wherein the first target electric signal and the positioning electric signal are discrete electric signals.

The storage mode of the stored file in the mobile terminal may include two modes of decentralized storage and whole storage, specifically, when the stored file is stored in the mobile terminal in a decentralized storage mode, the information stored in the mobile terminal by each stored file is a positioning electric signal corresponding to the stored file, the positioning electric signal is a discrete electric signal, the discrete electric signal refers to an electric signal with discontinuous time and continuous amplitude, for example, the positioning electric signal corresponding to the picture 1 may be a discrete electric signal f [ (D11 p, D12p,..1 m) p ] formed by a group of electric signals with discontinuous time and continuous amplitude, the positioning electric signal corresponding to the picture 2 may be a discrete electric signal f [ (D21 p, D22p,..d (2 m) p) ] formed by another group of electric signals with discontinuous time and continuous amplitude, and so on, so the mobile terminal may directly obtain the positioning electric signal corresponding to each stored file from the local memory.

In other embodiments, when the stored files are stored in the mobile terminal in a manner of being stored entirely, the information stored in the mobile terminal by each stored file is generally digital information, for example, digital information representing the stored files formed by using different combinations of numbers 0 and 1, where the S102 may specifically include:

S1021: first digital information of each stored file in the mobile terminal is acquired.

The first digital information is stored data of the stored file in the mobile terminal, and specifically, the first digital information may be obtained by performing analog-to-digital conversion on a corresponding file in a storage process of the file.

S1022: and loading the first digital information on a preset discrete electric signal to obtain a positioning electric signal corresponding to each stored file.

The preset discrete electric signal can be a sinusoidal discrete electric signal, and the amplitude of the sinusoidal discrete electric signal can be set to be [ -W, W ], wherein W >1, and the frequency of the sinusoidal discrete electric signal is n/2 pi. If the information is expected to be loaded quickly, the frequency of the sinusoidal discrete electric signal is increased, namely n is increased; if more information is desired to be loaded, the amplitude, i.e. the W, is increased, which can be considered in detail.

In specific implementation, the length of the first digital information can be obtained, the information loading length of the corresponding preset discrete electric signal is determined according to the length of the first digital information, and then the corresponding first digital information is loaded onto the preset discrete electric signal according to the information loading length of the preset discrete electric signal, so that the positioning electric signal corresponding to the corresponding stored file is obtained. Thus, by loading the digital information of each stored file on a corresponding preset discrete electrical signal, the resulting locating electrical signal of that stored file is also a discrete electrical signal, i.e., the locating electrical signal may be understood as a discrete electrical signal loaded with the digital information of the stored file.

In some embodiments, when the stored file is stored in the mobile terminal in a scattered storage manner, correspondingly, before S102, the method may further include: in the process of storing files, storing each file to be stored in a scattered storage mode to obtain storage information of the corresponding stored file (namely positioning electric signals corresponding to the stored file), and in the implementation, each file to be stored can be subjected to analog-to-digital conversion to obtain digital information of each file to be stored; acquiring the length of digital information of each file to be stored, and determining the information loading length of a corresponding preset discrete electric signal according to the length of the digital information; according to the information loading length of the preset discrete electric signal, loading the digital information of the file to be stored onto the preset discrete electric signal to obtain the corresponding storage information of the file to be stored (namely the positioning electric signal corresponding to the stored file), and storing the corresponding relation between the positioning electric signal and the stored picture, so that the user can check the stored file conveniently. Therefore, the file storage process and the file searching process can be matched, so that the time for converting the digital information of the stored file into discrete electric signals can be saved in the subsequent searching process of the stored file, and the searching efficiency is improved.

In this embodiment, when the first target feature information is a keyword, the S102 may further include:

s1023: and determining second digital information corresponding to the first target characteristic information.

Specifically, the mobile terminal may store second digital information corresponding to different first target feature information, and after obtaining the first target feature information input by the user, the corresponding second digital information may be found according to the first target feature information. The second digital information may be main file information representing a picture or video file having the first target feature information, the main file information being capable of distinguishing the file having the first target feature information from the file not having the first target feature information, for example, when the first target feature information is a keyword of "face", the second digital information may be face partial image information or video frame information representing a face picture or a face shot video existing using different combinations of the numbers 0, 1.

S1024: and loading the second digital information onto a preset discrete electric signal to obtain a first target electric signal corresponding to the first target characteristic information.

Specifically, the length of the second digital information can be obtained, and the information loading length of the corresponding preset discrete signal is determined according to the length of the second digital information; and loading the second digital information onto the corresponding preset discrete signal according to the information loading length to obtain a first target electric signal, wherein the first target electric signal can be understood as the discrete electric signal loaded with the second digital information.

In other embodiments, when the first target feature information is a template file, the S102 may include:

s1025: and carrying out analog-to-digital conversion on the first target characteristic information to obtain third digital information of the first target characteristic information.

The template file may be a picture or video file temporarily shot by a camera of the mobile terminal when the user inputs the first target feature information on the file searching interface, or may be a template picture or template video stored locally in advance, or may be a template picture or template video stored in a server connected to the mobile terminal through a network in advance.

Specifically, after obtaining a template picture or video input by a user, performing analog-to-digital conversion on the template picture or video to obtain third digital information of the template picture or video, where the third digital information is used to represent main file information of the target picture or video. For example, when the first target feature information is a template picture, boundary contour recognition of a photographed object may be performed on the template picture to obtain contour information of the photographed object in the template picture, then a local image corresponding to the photographed object in the template picture is determined according to the contour information of the photographed object, the local image is used as main file information of the template picture, and then analog-to-digital conversion is performed on the main file information of the template picture to obtain third digital information of the first target feature information.

S1026: and loading the third digital information onto a preset discrete electric signal to obtain a first target electric signal corresponding to the first target characteristic information.

Specifically, the length of the third digital information can be obtained, and the information loading length of the corresponding preset discrete signal is determined according to the length of the third digital information; and loading the third digital information onto the corresponding preset discrete signal according to the information loading length to obtain a first target electric signal, wherein the first target electric signal can be understood as the discrete electric signal loaded with the third digital information.

S103: searching a stored file conforming to the first target characteristic information according to the first target electric signal and the positioning electric signal.

As shown in fig. 3, S103 may specifically include:

s1031: judging whether a signal segment matched with the first target electric signal exists in the positioning electric signal, if so, executing S1032, and if not, prompting a user to redetermine the first target characteristic information.

The positioning electric signal and the first target electric signal are both discrete electric signals, that is, both the positioning electric signal and the first target electric signal include a plurality of electric signal segments with discontinuous time and continuous amplitude, and because the amount of information loaded on the positioning electric signal is generally greater than the amount of information loaded on the first target electric signal, the number of electric signal segments in the positioning electric signal is generally greater than the number of electric signal segments in the first target electric signal.

S1032: and taking the stored file corresponding to the corresponding positioning electric signal as the stored file conforming to the first target characteristic information.

In some embodiments, the file searching instruction may further carry second target feature information, and after S103, the method may further include:

s104: and determining a second target electric signal corresponding to the second target characteristic information.

Specifically, as shown in fig. 4, when a user needs to search a picture or a video file stored in the mobile terminal, the user may input second target feature information in addition to the first target feature information in the file search interface, and then the mobile terminal may receive a file search instruction triggered by an input operation of the user on the first target feature information and the second target feature information, where the file search instruction may carry the first target feature information and the second target feature information.

The first target feature information and the second target feature information may be two types of feature information of a picture or a video file that the user needs to search, for example, the first target feature information is a keyword "face", the second target feature information is a keyword "building", and then the picture or the video file that the user needs to search should have the picture information or the video information of the face and the building at the same time. In other embodiments, the second target feature information may be further detailed in the first target feature information, for example, the first target feature information is a keyword "face", and the second target feature information is an "old face".

In this embodiment, the second target feature information may be the same as the first target feature information, and the specific embodiment of S104 may refer to the specific implementation manners of S1023, S1024, S1025 and S1026, so that the description is omitted here.

S105: searching the stored file conforming to the first target characteristic information and the second target characteristic information according to the second target electric signal and the positioning electric signal corresponding to the stored file conforming to the first target characteristic information.

Wherein, the step S105 may specifically include:

s1051: and judging whether a signal segment matched with the second target electric signal exists in the positioning electric signal corresponding to the stored file conforming to the first target characteristic information, if so, executing S1052, and if not, prompting a user to redetermine the second target characteristic information.

The positioning electric signal and the second target electric signal are both discrete electric signals, that is, both the positioning electric signal and the second target electric signal include a plurality of electric signal segments with discontinuous time and continuous amplitude, and because the amount of information loaded on the positioning electric signal is generally greater than the amount of information loaded on the second target electric signal, the number of electric signal segments in the positioning electric signal is generally greater than the number of electric signal segments in the second target electric signal.

S1052: and taking the stored file corresponding to the corresponding positioning electric signal as the stored file conforming to the first target characteristic information.

And by analogy, when a user needs to search the picture or video file stored in the mobile terminal, besides the first target feature information and the second target feature information, a plurality of target feature information such as third target feature information and fourth target feature information can be input in a file searching interface, so that the picture or video file which the user needs to search can be positioned in multiple layers, and file searching efficiency is improved.

In other alternative embodiments, when the number of the stored files that meet the first target feature information is found to be greater, for example, greater than a preset number threshold (e.g., 100), after S103, the method may further include: displaying a prompt dialog to the user to enable the user to determine whether to input the second target feature information; after the user inputs the second target feature information, the second target feature information input by the user is acquired, and a second target positioning signal corresponding to the second target feature information is determined, so that the range of the picture or video file to be searched by the user is reduced layer by layer, and the accuracy of file searching can be improved.

Compared with the prior art, the file searching method in the embodiment is applied to the mobile terminal, the file searching instruction is obtained, the file searching instruction carries the first target feature information, then the first target electric signal corresponding to the first target feature information is determined, the positioning electric signal corresponding to each stored file in the mobile terminal is determined according to the file searching instruction, the first target electric signal and the positioning electric signal are discrete electric signals, and then the stored file conforming to the first target feature information is searched according to the first target electric signal and the positioning electric signal, so that when searching the picture or video file stored in the mobile terminal, the picture or video file required by a user can be quickly positioned, and meanwhile power consumption is reduced.
