Specific embodiment
In below describing, in order to illustrate rather than in order to limit, it is proposed that the such as tool of particular system structure, technology etc
Body details, thoroughly to understand the embodiment of the present invention.However, it will be clear to one skilled in the art that concrete without these
The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known system, device, electricity
Road and the detailed description of method, in case unnecessary details hinders description of the invention.
In embodiments of the present invention, start photographic head, perform shooting operation；Detect on the image shot in the photographic head
The multiple spot grasping manipulation of generation, determines the encirclement area that the multiple spot grasping manipulation is formed on the image that the photographic head shoots
Domain；Extract the search content in the enclosing region；Search is completed based on the search content, Search Results are got.
In order to illustrate technical solutions according to the invention, illustrate below by specific embodiment.
What Fig. 1 showed the method for search of taking pictures provided in an embodiment of the present invention realizes flow process, and details are as follows：
In S101, start photographic head, perform shooting operation.
The realization of function of search of taking pictures firstly the need of completing to take pictures exercise question by photographic head, in the embodiment of the present invention
In, start photographic head, so that user is shot by manipulating photographic head to the search content on paper, wherein, the search
Content includes but is not limited to English word, words, paragraph word, exercise question or two-dimension code pattern.
In S102, the multiple spot grasping manipulation produced on the image shot in the photographic head is detected, determine the multiple spot
The enclosing region that grasping manipulation is formed on the image that the photographic head shoots.
After photographic head shooting is completed, the image that it shoots can be shown on a terminal screen, now, Yong Huke
Multiple spot grasping manipulation (for example, the five fingers grasping manipulation) is carried out with the image to showing on screen, user will first refer to that nature falls more
On screen, then central areas of pointing to are slided more, realize multiple spot grasping manipulation, and passing through smoothed curve will refer to initial nature more
Fall some touch screen points connection formed on screen, and the enclosing region for being formed is the multiple spot grasping manipulation and shoots in photographic head
Image on formed enclosing region.
In S103, the search content in the enclosing region is extracted.
In S104, search is completed based on the search content, get Search Results.
In embodiments of the present invention, the encirclement of multiple spot grasping manipulation formation is intercepted out on the image that photographic head shoots first
Region, carries out content recognition to the image of the enclosing region afterwards.Firstly, since the search content of search of taking pictures is mostly text
Format content, because in most of the cases, in the image of shooting, the pixel color of textual portions is black, paper part
Pixel color is white, therefore the text in image can be distinguished by analysis pixel color, and by analyzing the row of text
The paragraph format of spacing or text searches for the zone boundary of content to determine, so as to further intercept out search content graph
Picture.After search content images are intercepted out, by optical character recognition (Optical Character Recognition,
OCR the word in search content images) is identified, and the search content of text formatting is generated according to recognition result, so as in clothes
The Search Results of the search content are matched in business device background data base, to present to user.
As one embodiment of the present of invention, as shown in Fig. 2 S104 specifically can be accomplished by：
In S201, the search-type is determined according to the area of the enclosing region.
In S202, the search to the search content is completed in the corresponding data base of the search-type, got
Search Results.
The corresponding search content occupied area of different search-types is also different, be therefore, it can according to enclosing region
Area determining search-type, specifically：
If the area of the enclosing region is less than default area threshold, it is that word or words are released to determine the search-type
Justice search.If user needs the lexical or textual analysis of searching words or words, due to the text area shared by word or words it is less, for example,
Only several English or Chinese combinatorics on words, therefore, if detecting the area of enclosing region less than a certain default area threshold,
Then it is believed that now corresponding search-type is that word or words lexical or textual analysis are searched for.
If the area of the enclosing region is more than or equal to the default area threshold, determine that the search-type is section
Fall character translation or exercise question search.If user needs translation result or the answer of exercise question for searching for paragraph word, then obviously, right
For paragraph word or exercise question, the text area shared by it is larger, may occupy the text filed of some rows, therefore, if
The area of enclosing region is detected more than a certain default area threshold, then it is believed that now corresponding search-type is paragraph text
Word is translated or exercise question search.
After search-type is determined, then server end can complete right according to search-type in corresponding data base
The search of search content, so, the execution of search operation can be more purposive, and hunting zone clearly, improves search
Efficiency.
Additionally, as one embodiment of the present of invention, as shown in figure 3, S104 specifically can be accomplished by：
In S301, judge whether the search content is coded graphics, and the coded graphics includes Quick Response Code or bar shaped
Code.
In S302, if the search content is the coded graphics, the coded graphics is decoded, obtained according to solution digital content
Get Search Results.
For coded graphics, such as Quick Response Code or bar code, because its corresponding display content possesses certain
Marked feature, for example, bar code is that the nicking differed by the width of a plurality of black is constituted, and Quick Response Code is by multiple sizes
What the black color lump for differing was constituted, therefore, it can directly identify whether search content is code pattern according to above-mentioned marked feature
Shape, if it is, directly decode to the coded graphics, decodes the information carried in coded graphics, and according to parsing
Information carry out feedback search result.For example, when the information for parsing is network address, then the network address is accessed, downloads corresponding net
Page content feed is to user.
Further, S104 can be realized by way of shown in Fig. 4：
In S401, the search content to extracting shows, so that user is true according to the search content input for showing
Recognize instruction or cancel instruction.
In S402, if detecting the confirmation instruction input, search is completed based on the search content, get search
As a result.
In the embodiment shown in fig. 4, after extracting search content, the search content is shown, so that user is confirmed in search
Hold extract correctness, only user confirm and have input confirmation instruction after, just communicated with server background, perform
Search operation, with the correctness for ensureing to search for content.
In embodiments of the present invention, the search content in the image that photographic head shoots is determined by multi-fingered grasp operation,
The accuracy that contents extraction is searched in search procedure of taking pictures is ensure that, the operating efficiency of search of taking pictures is improve.
It should be understood that the size of the sequence number of each step is not meant to the priority of execution sequence, each process in above-described embodiment
Execution sequence should be determined with its function and internal logic, and any limit should not be constituted to the implementation process of the embodiment of the present invention
It is fixed.
