Embodiment 1
The photographic quality that photo influences to shoot is shot to solve in the prior art to trigger camera by pressing operation
Problem, the embodiment of the present application 1 provides a kind of photographing instruction sending method.The photographing instruction sending method that the embodiment of the present application is provided
Executive agent can be terminal device, for example, mobile phone, tablet personal computer, etc. or perform photographing instruction sending method
Software.
For ease of description, hereafter using terminal device as exemplified by performing this method main body, the embodiment to this method is entered
Row is introduced.It is appreciated that being a kind of exemplary explanation using terminal device as this method main body is performed, it is not construed as
Restriction to this method.
The implementation process schematic diagram of this method is as shown in figure 1, comprise the steps：
Step S101：Determine area accounting of the target area in preview image；
Here preview image is the image in camera lens view-finder collected in real time after camera is opened, and preview image can
For user's preview, to select suitable shooting angle and opportunity to take pictures, when camera is opened, multiframe can be continuously got
Preview image.The preview image determined in this step can be got at camera current time, can so be taken pictures in satisfaction
During condition, camera is controlled to go to take pictures in time.
Target identification thing can be reference object of the camera when taking pictures, and target identification thing such as can be preliminary dimension
Card, such as debit card, credit card, business card, member card, access card, mass transit card etc..The preliminary dimension can be Standard Bank
The size of card, or most standard business card size, etc..
Target area is target identification thing region residing in preview image, then target area is in preview image
Area accounting, can be ratio of the area with the preview image gross area of target area.It is determined that target area is in preview image
In area accounting when, can first determine the target area in preview image, target area and preview image are then calculated again
Area accounting.
, can be by determining the border of target identification thing in preview image it is determined that during target area in preview image
Line determines that the region that the boundary line of target identification thing is surrounded is regarded as region of the target identification thing in preview image,
That is target area.Such as, for the card of preliminary dimension, because the edge of card is often four line segments, then can root
According to four line segments for meeting default second condition detected in presumptive area, to determine the border of the target area where card
Determination card target area in preview image will will be described in detail as target area in line, the region that boundary line is surrounded hereinafter
The step of domain, do not repeat herein.
, can be in target area in preview in order to obtain clear photograph, the i.e. higher photo of target identification thing identification
Accounting goes to shoot compared with Gao Shizai in image, then can first determine the area accounting, the determination method of specific area accounting is such as
Can be：By the ratio of target area pixel quantity and the total pixel quantity of preview image, as target area in preview graph
Area accounting as in.
For target identification thing is card, target area is generally rectangular cross-section, then can be according to four recognized
Line segment calculates the area accounting of target area.Specifically, can multiplying according to target area adjacent two edges pixel quantity
Product, determines the pixel quantity of target area, then with target area pixel quantity divided by the total pixel quantity of preview image,
It can obtain area accounting of the target area in preview image；Or, can be according to the length of target area adjacent two edges
Product, the area of preview image is determined, then with the area divided by the preview image gross area of preview image, you can obtain target
Area accounting of the region in preview image.
In actual applications, it is determined that during area accounting, determined by calculation as described above,
Can also be determined by obtaining the area accounting of other devices offers, the application is not limited this.
Step S102：When the area accounting meets default first condition, to camera corresponding with the preview image
Send photographing instruction.
Default first condition described here can be that the area accounting is being preset in span, the default value model
Enclosing to pre-set.When the area accounting is in default span, the definition of target identification thing can expire
The default definition requirement of foot.Definition requirement mentioned here such as can be that the target identification thing in image can visually be known
Not, the target identification thing or in image can be by optical character identification (Optical Character Recognition, OCR)
Unit is recognized.
Such as, it is determined that area accounting of the target area in preview image be 0.8, if area accounting set in advance
Span be 0.75~0.95, then can be considered that the area accounting that is determined in step 12 meets default first condition, i.e.,
Photographing instruction can be sent to camera corresponding with preview image.Here camera corresponding with preview image can obtain that this is pre-
Look at the camera of image.
For example, so that target identification thing is the card of pre-set dimension as an example, when being taken pictures to the card, the is preset
When one condition can be that the definition of the card meets default definition requirement, image-region and preview graph image planes where card
The span of product accounting.
The photographing instruction sending method that the application is provided is particularly suitable for use in quiet zoom lens, and quiet zoom lens here refer to when taking pictures
Can not the camera lens that can not adjust of auto-focusing and focal length, quiet zoom lens for other feature-rich camera lenses low cost,
Size is small, can apply in more scene, such as, for the ultra-thin terminal device of volume, because mirror is installed in its inconvenience
The larger zoom lens of head volume or the camera lens for being capable of auto-focusing, therefore quiet zoom lens are a kind of selections well.
Because the focal length of quiet zoom lens is fixed, then the definition of target identification thing and target identification object distance in image
It is related from a distance from camera lens, when target identification thing is closer to apart from the distance and focal length of camera lens, mesh in the image shot
The definition for identifying other thing can be higher；Also, when the timing of size one of target identification thing, the accounting of target area in the picture with
Target identification thing is linear correlation apart from the distance of camera lens, when target identification thing is nearer apart from camera lens, and target area is in figure
Accounting as in can be larger.That is there is corresponding relation in target area accounting in the picture and the definition of image.
So, for target identification thing that the quiet zoom lens of parameter identical and size are preliminary dimension, it may be predetermined that
The camera lens can clearly photographic subjects marker when, the span of target area area accounting in preview image.So,
When being taken pictures again with the quiet zoom lens of identical parameters to the target identification thing of preliminary dimension next time, you can according to target area in institute
State the area accounting in preview image, come judge target identification thing in preview image it is whether clear.Certain ginseng mentioned here
It is not absolute identical that number is identical, for different camera lens, as long as the corresponding relation phase of image accounting and definition
With.
In order to prevent causing to take pictures of poor quality because camera lens such as rocks at the reason, the pre- of continuous sampling can be such as preset
Number of image frames is look at, when the area accounting of the continuous predetermined frame number preview image is satisfied by default first condition, to sampling phase
Machine sends photographing instruction, controls the sampling camera automatic camera, sampling camera here can be for obtaining preview image
Camera.Certainly, area accounting here refers to area accounting of the target area in preview image, as it was noted above, phase chance is pressed
Preview image is obtained according to certain picture-taken frequency, each preview image is a frame, then can determine that each frame is pre- respectively
Look at the area accounting of image, when the area accounting of the preview image of continuous predetermined frame number is satisfied by default first condition, i.e. table
Rocking for bright mirror head now just can send photographing instruction, to obtain higher shooting matter in range of receiving to sampling camera
The photo of amount.
Camera is after photographing instruction is received, you can perform photographing operation.Then the image of camera shooting can be received,
According to the boundary line of determination, the image of the target area is intercepted in the image shot from camera, the figure of target identification thing is used as
Picture.Region unnecessary beyond objective area in image image is so just can remove, storage area can be both saved, can also expire
Processing requirement of the sufficient later stage to image.
After the image of target identification thing is obtained, spatial alternation can also be carried out to the image of target identification thing, to cause
Target identification thing in image is in preset state.Preset state is state set in advance, and herein, preset state can be just
Depending on state, face the image of state, refer to when sight is perpendicular to objective plane, it is acquired without translating, rotate, scale, inclining
The image of the spatial alternations such as oblique and perspective.Such as, for business card, the acquisition of the image is by determined by will be in image
Name panel region, by projective transformation, is transformed to advise the business card image intercepted out after positive rectangular shape.
Below using by card as the photographing instruction sending method that the application offer exemplified by target identification thing, is discussed in detail,
The implementation process schematic diagram of this method as described in Figure 2, comprises the steps：
Step S201：Determine in the presumptive area of the preview image in the presence of four line segments for meeting default second condition；
Because the area accounting when the card in image is more visible in preview image is often than larger, then card
Four edges can be nearer with the frontier distance of image, therefore presumptive area is preferably in the fringe region of image, i.e. presumptive area
Each pixel and the distance of closest image boundary be less than preset distance.As shown in figure 3, presumptive area inside border away from
From being x respectively with a distance from adjacent image boundary1, x2, x3, x4, the presumptive area can be by developer according to area above
Accounting is set, and is defined by four marginal positions that card can be detected in image clearly.
Here default second condition, can be the line segment that there is length in presumptive area in the range of preset length, this
In preset length scope can be determined according to specific card sizes.Certainly, the image collected due to camera is often not
The characteristics of image of target identification thing can completely be reduced, such as it is, relative in possible image for some edge of card
The characteristics of image answered is some discontinuous line segments, then, these line segments can at this time be merged, specifically merge line segment
When, it can be merged for the close line segment of in small distance, angle, then the length of line segment after merging is in preset length
In the range of when, then can be using the corresponding line segment in the border of the line segment as card.Card border corresponding four was so both can obtain
Bar line segment.
If it should be noted that the quantity for the line segment for being not detected by line segment or detecting is less than two, then it is assumed that not
Line segment is recognized, preview image frame can be reacquired, the operation such as image denoising is then performed to picture frame, then preview image is entered
Row detection.The straight line in presumptive area can be specifically detected by the line detection algorithm for image.
Step S202：According to four line segments in presumptive area, the boundary line of the target area where the card is determined.
Because the image that camera is collected tends not to completely reduce the characteristics of image of target identification thing, therefore detect
The corresponding each bar line segment of card border be possible to can be shorter than card actual edge size, or than card actual edge size
Grow, cause four line segments can not be end to end.So the extended line of four line segments can two-by-two be intersected and obtain four intersection points,
The connected obtained quadrangle of four intersection points can be used as the boundary line of card, and now the region in card boundary line institute frame is mesh
Mark region.
Step S203：Determine area accounting of the corresponding target area of card in the preview image；
The specific mode for determining area accounting can be found in the associated description in step S101, and here is omitted.
Step S204：When it is determined that area accounting meet default first condition when, to corresponding with the preview image
Camera sends photographing instruction.
The default first condition can be that area accounting is being preset in span, when area accounting is in default value model
When enclosing interior, the definition of target identification thing can meet default definition requirement.
, can be when continuous predetermined frame number preview graph in order to prevent causing photographic quality poor because camera lens such as rocks at the reason
When the area accounting of picture is satisfied by default first condition, photographing instruction is sent to camera corresponding with the preview image.
Camera is after photographing instruction is received, you can perform photographing operation.
Step S205：The image of camera collection is received, according to the boundary line of determination, image is intercepted, card is used as
Image；
Objective area in image so just be can remove with the image of exterior domain, storage area so can be both saved, also may be used
To meet processing requirement of the later stage to image.I.e. according to the boundary line of determination, intercepted in the image shot from the camera
The image of the target area, is used as the image of target identification thing.
Step S206：Spatial alternation is carried out to the image of card, to cause the card in image to be in preset state.
Here preset state such as can be to face state, for target identification thing is card, and card is in just
Can be that the four edges of card are just overlapped with the edge line of image depending on state.It is outer by the image obtained after spatial alternation
The similar actual business cards of shape, the image without other background image contents, the four edges of business card image are the boundary line of business card.
The method that the embodiment of the present application 1 is provided, by determining the target area where the target identification thing in preview image,
Then when it is determined that area accounting of the target area in the preview image meets default first condition, to the preview graph
As corresponding camera transmission photographing instruction, user is without trigger camera bat by performing pressing operation during entirely taking pictures
According to, it is to avoid camera produce it is unnecessary rock, and then avoid the problem of photographic quality of shooting is poor.
Whether the application can be according to area accounting of the target area in preview image, to detect card in clearly
State, relative to being detected in the prior art by modes such as pixel values, the process resource of consuming is less.And in presumptive area
Each pixel and the distance of closest image boundary to be less than preset distance, i.e. presumptive area be the side in preview image
Edge region, it so ensure that card goes to take pictures again when accounting is larger in preview image, and area accounting when taking pictures exists
Within the scope of area accounting during predetermined apparent, it can so cause the apparent shot, and accorded with size
Close requirement of the later stage to image procossing.
