To enable goal of the invention, feature, the advantage of the present invention more obvious and understandable, below in conjunction with the present invention
Accompanying drawing in embodiment, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that disclosed below
Embodiment be only a part of embodiment of the invention, and not all embodiment.Based on the embodiment in the present invention, this area
All other embodiment that those of ordinary skill is obtained under the premise of creative work is not made, belongs to protection of the present invention
Scope.
Embodiment one：
As shown in Fig. 2 being a kind of schematic flow diagram of method that photo is shot when sweeping topic provided in an embodiment of the present invention, institute
The method of stating can include：
Step S201, designated terminal receive execution sweep the instruction of topic after, call the camera of the designated terminal.
Usually, the button that the startup specified is taken pictures is both provided on the interface for sweeping topic application program, user clicks on this and pressed
Key (can also be triggered) by voice, fingerprint, gesture or physical button, that is, have issued the instruction for performing and sweeping topic.
Alternatively, calling the process of the camera of the designated terminal can include：
Obtain the rear camera number of the designated terminal；
If the designated terminal only one of which rear camera, the camera is chosen as preferred camera；If described
Designated terminal has more than two rear cameras, then a camera is therefrom chosen as preferred camera, as specific choosing
Which camera is selected, can be set according to actual conditions, the present embodiment is not especially limited to this；
Call the preferred camera.
Why when there is multiple rear cameras, only choosing one of them and being called, be because current terminal
It is in order that shooting the photo come more meets the aesthetic requirement of people, and is had no for text identification too big that multi-cam, which is set,
Effect, adds resource consumption when taking pictures and in processing procedure on the contrary.
Optionally, of course, simultaneously multiple cameras can also be called to be taken pictures according to the default setting of terminal system.
Step S202, the parameter of taking pictures of the camera is adjusted according to default regulative mode, to reduce and text
The unrelated information of this identification.
Due to requirement more and more higher of the current user for the effect of taking pictures of each Terminal Type, each Terminal Type is all constantly to it
The camera of carrying is upgraded, and the performance of camera is stronger and stronger, and these newly-increased functions can be very good to meet
The mankind's is aesthetic, but contains too many garbage for computer text identification, and this step is by camera
Parameter of taking pictures be adjusted, to reduce the information unrelated with text identification.
Now, can be using two kinds of different display patterns in the display interface for sweeping topic application and being presented to user：
The preview effect that photo is shot according to parameter of taking pictures described in after regulation, institute is shown in pattern one, display interface
See i.e. gained；
The preview effect that photo is shot according to parameter of taking pictures described in before regulation is shown in pattern two, display interface, i.e.,
The display effect of terminal system acquiescence.
Two kinds of display patterns cut both ways, according to pattern one, What You See Is What You Get, and user can be to shooting the effect of photo
Have and intuitively experience, but the pattern with user normally take pictures experience difference it is larger, user receive get up to have certain difficulty；If
Using pattern two, the pattern is normally taken pictures with user experience, it is easy to be easily accepted by a user, but for final effect of taking pictures
Really, user lacks and intuitively experienced.
Which kind of display pattern is specifically used, can be configured according to actual conditions, it is of course also possible in display interface
Upper to show both patterns simultaneously, the present embodiment is not especially limited to this.
Preferably, step S202 can specifically include：
Step S2021, default first numerical value is reduced to by the resolution ratio of the camera.
The resolution ratio that camera shoots photo generally refers to the pixel number that photo is included, and resolution ratio determines bitmap
As the fine degree of details.Under normal circumstances, the resolution ratio of image is higher, comprising pixel it is more, image is more clear,
The quality of printing is also better.Meanwhile, it can also increase the memory space of file occupancy.
In actual use, user shoots the image quality of photo in order to pursue, it is intended to using the camera of high-resolution, make
The resolution ratio that producer constantly lifts produced terminal camera is obtained, the resolution ratio of conventional terminal is all more than thousand in the market
The rank of ten thousand pixels.
And for application is inscribed in general sweeping, when it carries out text identification, and so high resolution ratio is not needed, additionally
Not only increased resolution ratio can not improve its recognition performance, the time that processing is compressed to photo can be increased on the contrary, therefore,
In the present embodiment, the resolution ratio of camera is preferably reduced to default first numerical value, first numerical value can be swept according to each
The actual conditions of topic application are configured, and the present embodiment is not especially limited to this.Preferably, can be by statistical method to not
Photo with resolution ratio carries out text identification, regard discrimination highest resolution ratio as first numerical value.
Step S203, is received in the designated terminal after the instruction for performing and taking pictures, and controls the camera according to regulation
The parameter of taking pictures afterwards shoots photo, and regard the photo obtained by shooting as the original photo that text identification is carried out when sweeping topic.
Usually, the tripper for shooting photo is both provided on the interface for sweeping topic application program, user clicks on the button
(can also be triggered by voice, fingerprint, gesture or physical button), that is, have issued the instruction for performing and taking pictures.
Sweep topic to apply after the original photo is obtained, it is pre-processed, then perform text identification, output is known
Text after not, scans for finally according to text, search result is fed back into user.These belong to prior art, this implementation
Example is repeated no more to its detailed process.
In summary, this programme embodiment designated terminal receive execution sweep the instruction of topic after, call the specified end
The camera at end；The parameter of taking pictures of the camera is adjusted according to default regulative mode, with reduction and text identification
Unrelated information；Received in the designated terminal after the instruction for performing and taking pictures, control the camera according to the institute after regulation
State parameter of taking pictures and shoot photo, and regard the photo obtained by shooting as the original photo that text identification is carried out when sweeping topic；It is described to press
According to default regulative mode the parameter of taking pictures of the camera is adjusted including：The resolution ratio of the camera is reduced to
Default first numerical value.It is that the parameter of taking pictures of camera is adjusted in the photograph taking stage, to reduce by the present embodiment
The information unrelated with text identification, for example, reduction resolution ratio, due to the default resolution of current end product it is general all compared with
Height, and have higher and higher trend, and for the text identification during sweeping topic, certain resolution ratio can meet it
Demand, not only extra increased resolution ratio can not improve its recognition performance, can increase on the contrary photo is compressed processing when
Between, therefore, it need not be taken additional time according to the photo for parameter shooting of taking pictures described in after regulation and it is handled, effectively
Accelerate Text Feature Extraction speed.
Embodiment two：
As shown in figure 3, being a kind of schematic flow diagram of method that photo is shot when sweeping topic provided in an embodiment of the present invention, institute
The method of stating can include：
Step S301, designated terminal receive execution sweep the instruction of topic after, call the camera of the designated terminal；
Step S302, the parameter of taking pictures of the camera is adjusted according to default regulative mode, to reduce and text
The unrelated information of this identification；
Step S303, is received in the designated terminal after the instruction for performing and taking pictures, and controls the camera according to regulation
The parameter of taking pictures afterwards shoots photo, and regard the photo obtained by shooting as the original photo that text identification is carried out when sweeping topic.
Wherein, step S301 is identical with the step S201 in embodiment one, step S303 and the step in embodiment one
S203 is identical, specifically can refer to the description in embodiment one, and the present embodiment is repeated no more to this.
Step S302 can specifically include：
Step S3021, default first numerical value is reduced to by the resolution ratio of the camera.
Step S3021 is identical with the step S2021 in embodiment one, specifically can refer to the description in embodiment one, this reality
Example is applied to repeat no more this.
Step S3022, default second value is brought up to by the acutance of the camera.
Camera shoots the acutance of photo, and " definition " is also sometimes, and it is reflection plane of delineation definition and image side
One index of the sharp keen degree of edge.If acutance heightened, the detail contrast on the plane of delineation is also higher, it appears that more clear
Chu.
In photography, the high sharpness of camera lens is a double-edged sword, on the one hand, it causes the visual effect of picture to become clear
It is clear, on the other hand, due to the raising of contrast, the main details that some get small thank for it originally can be amplified again, and cover secondary
Details is wanted, the decline of actual detail and the missing of level is caused, such as among portraiture photography, too high acutance causes application on human skin
Small scar, pimple be exaggerated and highlight (namely than it is actual visually look it is more obvious), so as to cause the coarse of face
And sensation of dryness, therefore, during portraiture photography, it will not typically select too high acutance.
But in this embodiment, because captured photo is to be used for text identification, the definition of photo can be directly influenced
The accuracy rate of text identification, therefore more pay close attention to the definition of photo, and be then to the flaw in some details for thus bringing can
With receiving.In the present embodiment, the acutance of the camera is preferably brought up into default second value, the second value
The actual conditions that topic application can be swept according to each are configured, and the present embodiment is not especially limited to this.Preferably, Ke Yitong
Cross statistical method and text identification is carried out to the photo of different acutancees, regard discrimination highest resolution ratio as the second value.
Step S3023, grayscale mode is adjusted to by the exposal model of the camera.
Grayscale mode refer to single tone show image, normally, the color of a pixel is represented with eight bits, one
Can show the gray tone (containing black and white) of 256 ranks (color range) altogether, that is, 256 kinds of lightness grey, be from black → ash → in vain
Transition, described black-and-white photograph is this pattern in daily life.
Why to be taken pictures using grayscale mode, be due to that the color information in photo is for text identification
Unnecessary, not only extra increased color information can not improve its recognition performance, can increase on the contrary and photo is carried out at gray processing
The time of reason, therefore, in the present embodiment, the exposal model of the camera is preferably adjusted to grayscale mode.
Further, color range difference excessive under grayscale mode is unnecessary for text identification, therefore can be use up
Under amount reduction color range value, extreme case, the exposal model of the camera can be adjusted to the white-black pattern of binaryzation, also
That the gray value of the pixel on image is set to 0 or 255, that is, whole image showed significantly only have it is black and white
Visual effect.For example, a gray threshold can be preset, the data of image are divided into two parts with the gray threshold：It is more than
The pixel group of the gray threshold and the pixel group less than the gray threshold.The pixel value that will be greater than the pixel group of the gray threshold is set
It is set to white (or black), the pixel value less than the pixel group of the gray threshold is set as black (or white).
It is especially noted that above step S3021, step S3022 and step S3023 have no the limit of precedence
It is fixed, its order can be adjusted according to actual needs, one of those or two can also be only selected according to the actual requirements
Step is performed, and other steps are refused to perform.Further, similar parameter can also be added according to the actual requirements to adjust
Save step, for example, the parameters such as aperture, shutter, sensitivity, focusing, light-metering, white balance are adjusted, the present embodiment to this not
Make specific limit.
In summary, this programme embodiment further increases the bat to the camera on the basis of embodiment one
The mode being adjusted according to parameter, can also be by institute except the resolution ratio of the camera is reduced into default first numerical value
The acutance for stating camera brings up to default second value, the exposal model of the camera is adjusted into grayscale mode.Pass through
The present embodiment, is that the parameter of taking pictures of camera is adjusted in the photograph taking stage, to reduce the letter unrelated with text identification
Breath, for example, reduction resolution ratio, improves acutance, sets grayscale mode etc., according to the photo for parameter shooting of taking pictures described in after regulation
It need not take additional time and it is handled, effectively accelerate Text Feature Extraction speed.
