Specific embodiment

In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, Detailed description of the invention will be compareed below A specific embodiment of the invention.It should be evident that drawings in the following description are only some embodiments of the invention, for For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other Attached drawing, and obtain other embodiments.

To make simplified form, part related to the present invention is only schematically shown in each figure, they are not represented Its practical structures as product.In addition, there is identical structure or function in some figures so that simplified form is easy to understand Component only symbolically depicts one of those, or has only marked one of those.In addition, unless otherwise instructed, in this hair " upper and lower " of bright middle appearance, " left and right ", " forward and backward ", " one, another " etc. are relative concept.

In one embodiment of the invention, as shown in Figure 1, a kind of automatic photography patterning process, comprising:

The profile information of step S100 acquisition photographic subjects.

Specifically, as needed, photographic subjects can be adult or children, it can be one or more personages.Work as shooting When target is personage, profile information include the head of people, body, each artis location information, can by these location informations To describe the appearance profile of a people.Since profile information is for photography composition service, so not needing to obtain body curve's Precise information, volume available is slightly larger and the simple closed geometry body of characteristic replaces.As an example, one as shown in Figure 6 The profile information of people, wherein head position information is expressed with the position of the rectangle frame (head frame 1) comprising head, further Ground can use the upper left point coordinate and lower-right most point coordinate representation of head frame, or be indicated with lower-left point coordinates and upper right point coordinates；Body Location information is expressed with the position of the rectangle frame (body frame 3) comprising body, further, can be sat with the upper left point of body frame Mark and lower-right most point coordinate representation, or indicated with lower-left point coordinates and upper right point coordinates；Each artis, with the central point in each joint The coordinate of (artis 4) is expressed；The data volume of processing can be reduced in this way, reduced and calculated photography complexity.Profile information can lead to Cross human testing, critical point detection technology obtains.

Step S200 generates initial composition frame to the photographic subjects according to the profile information.

Specifically, composition frame refers to the closure frame with certain shapes and size, for limiting the shape, big of photographic picture It is small.In general, composition frame is rectangle frame, left and right width is greater than upper-lower height.As needed, it is rotated by 90 ° in such as camera When realizing perpendicular clap, the upper-lower height of composition frame is then greater than left and right width.The ratio between wide height of composition frame is to have certain requirements, mainly The size of sensor depending on photographic units such as cameras, popular has 3:2 format, and there are also the formats such as 1:1,4:3, so Composition frame needs to meet preset photography the ratio of width to height requirement.

Destruction personage's integrality such as limb is cut off or cut in order to avoid occurring photographic subjects in the picture exported of photographing, image The phenomenon that, it needs to generate composition frame according to the profile information of photographic subjects.Optionally, it is required according to photography, for example, only needing to shoot The upper part of the body of personage, then extract the upper part of the body information of photographic subjects from profile information, and composition frame can only include photographic subjects Upper part of the body information；If being required without special photography, usually press and guarantee that the entire integrality of personage considers, composition frame needs include The entire profile information of photographic subjects.

In addition, according to composition rule, photographic subjects usually require to be placed in order to protrude photographic subjects, promote shooting quality The central area position of composition frame.As a preferred embodiment, optionally it is also possible to consider photographies to want according to profile information It asks, obtains the external envelope frame of photographic subjects；Using the center of the external envelope frame as the center of composition frame, then it is wide high by preset photography Than obtaining the rectangle frame of a complete external envelope frame comprising photographic subjects, a more satisfactory composition frame is so obtained, until It is the composition frame for meeting predeterminated position composition rule and pre-set dimension composition rule less, i.e., by taking personage is shone as an example, if this composition There was only photographic subjects in frame, without other personages, exports and photograph by this composition frame, then photographic subjects are in picture (or photo) Corresponding position meets position composition rule, and size of the photographic subjects in picture (or photo) is also to meet size composition rule Then.Predeterminated position/size composition rule is upper in picture (or photo) to photographic subjects according to the aesthetic requirement of shooting The set of the default judgement of the factors such as lower left and right spatial position/size.

To sum up, the above-mentioned composition frame obtained according to the profile information of photographic subjects, referred to as initial composition frame.

Step S300, which judges to whether there is in the initial composition frame, accompanies body, described to accompany body photographic subjects for other.

Specifically, body is accompanied to refer to that other similar with photographic subjects can photographic subjects.For example, photographic subjects are natural person When, accompany body for other people or crowd.In the occasion of such as more people's aggregation, by photographic subjects (specific one natural person) and one It is a or it is multiple accompany body (other natural persons) to carry out identification differentiation, so as to be obtained as far as possible using photographic subjects as image center Composition frame, and then obtain such as only including the single portrait of photographic subjects.So being needed to promote the shooting quality of photographic subjects Judge in initial composition frame in addition to photographic subjects, if there is also accompany body or accompany body a part (i.e. initial composition frame with accompany Body exists overlapping).It may be there is no accompanying body in initial composition frame, or there are one to accompany body, or accompanies body there are multiple.

Step S400 when in the initial composition frame there is no accompany body when, using the initial composition frame as target pattern frame Output.

Specifically, showing that the initial composition frame currently formed only includes photographic subjects there is no body is accompanied in initial composition frame. Since current composition frame has been more satisfactory composition frame, can obtain only include such as single people photo, so can should Initial composition frame is exported as target pattern frame.

Step S500 judges whether there is one and accompanies body must be also as bat when in the initial composition frame in the presence of body is accompanied Take the photograph target.

Specifically, the influence for considering to accompany body is needed, for example, accompanying physical efficiency no from structure when in initial composition frame in the presence of body is accompanied It is removed in picture frame, still must also be used as photographic subjects.If can remove from composition frame, photographic subjects can be further promoted Shooting effect.In initial composition frame there may be one accompany body or it is multiple accompany body, whether judgement each accompanies body that must respectively As photographic subjects, obtaining further according to each judging result for accompanying body must also accompanying as photographic subjects with the presence or absence of one Body.Each accompany the judging means of body can be with are as follows: the overlapping area for accompanying body Yu initial composition frame to be calculated, if the overlapping area is greater than Preset value, then this accompanies body that must also be used as photographic subjects.Preferably, the overlapping area for each accompanying body Yu initial composition frame is calculated, And calculate the ratio that the area accounts for the entire area for accompanying body.When the ratio is greater than or equal to preset value, then this accompanies body necessary Also photographic subjects are used as；Otherwise, this accompanies body not as photographic subjects.As shown in fig. 7, there are one in initial composition frame to accompany body, Wherein big frame indicates that initial composition frame, the expression of small frame accompany body, left side figure be accompany body must also as an example of photographic subjects, The right figure is an example for accompanying body not as photographic subjects；Left side figure, which reflects, accompanies the most of in initial composition frame of body, Illustrate that body is accompanied to be closer with photographic subjects, even if body can will be accompanied to remove by mobile initial composition frame, but such photographic subjects Also it can be in the edge of initial composition frame, do not meet default composition rule, so such case needs will accompany body also as shooting A part of target.

Step S600, which exists in the initial composition frame, accompanies body, and all when accompanying body all not as photographic subjects, again Generation accompanies body disturbance degree no more than current composition frame, and exports as target pattern frame.

Body is accompanied specifically, existing in the initial composition frame, if all when accompanying body all not as photographic subjects, illustrate own Accompany influence all very little of the body to initial composition frame.Such case can accompany body disturbance degree smaller than current composition frame by regenerating Composition frame further promote shooting quality.Body disturbance degree is accompanied to reflect the influence for accompanying body to composition frame, for example, by accompanying body Accounting for the overlapping area of composition frame or the overlapping area accompanies the ratio of body to judge.

For example, exist in the composition frame as shown in figure 8, the left side is initial composition frame and accompany body, the overlapping of body and composition frame is accompanied Area, which accounts for, accompanies the ratio of the entire area of body small, belongs to and accompanies the case where body is not as photographic subjects；By moving to left composition frame, the right side is obtained The composition frame on side has been not present in the composition frame and has accompanied body, and accompanying the overlapping area of body and composition frame is 0, and body disturbance degree is accompanied to reduce, It can be exported as target pattern frame.

For another example, as shown in figure 9, the left side is initial composition frame, exist in the composition frame and accompany body, moving to left composition frame to keep away When accompanying body on the right of exempting from, the left side occurs newly accompanying body again, it is apparent that the left side newly accompanies the overlapping area of body and composition frame than initial structure Picture frame it is smaller, so can obtain one accompanies the smaller composition frame of body disturbance degree, can be exported as target pattern frame.

In other instances, relatively initial composition frame possibly can not retrieve and accompany the smaller composition frame of body disturbance degree, but It is smaller due to accompanying body to influence, practical photograph is avoided even exporting initial composition frame and can also cut by the photo after such as photographing Exist in piece and accompanies body.Further, when there are it is a variety of accompany body disturbance degree smaller composition frame when, therefrom selection accompanies body disturbance degree most Small composition frame is exported as target pattern frame.

Step S700, which works as to exist in the initial composition frame, accompanies body, and at least accompanies body that must also be used as in the presence of one and shoot mesh When mark, also body and the photographic subjects will must be accompanied to constitute new photographic subjects as photographic subjects, and replaced with new photographic subjects For photographic subjects, step S100 is jumped to.

Specifically, accompany body there are one in the initial composition frame, and when this is accompanied body also and must be incorporated into photographic subjects, this is accompanied Body and photographic subjects combination, obtain new photographic subjects, replace photographic subjects with new photographic subjects, restart new round target structure The generation of picture frame, output process.When accompanying body there are multiple in initial composition frame, and some or all accompany body must be as shooting mesh When mark, also body and photographic subjects must be accompanied to combine as photographic subjects by all, new photographic subjects be obtained, with new photographic subjects Instead of photographic subjects, restart generation, the output process of new round target pattern frame.

Usual photographic process is: discovery photographic subjects, adjustment photographic unit (such as camera) are directed at photographic subjects, are taking the photograph at this time There is the image comprising photographic subjects in the visual field of shadow component, composition frame then is set to the photographic subjects in present image (preview pane in similar digital camera)；If satisfied to the image in composition frame, photography is executed.So in setting composition frame Before, has the image comprising photographic subjects in the visual field of photographic unit, if it is the intensive scene of more people, which can The profile information of all persons in the image can be obtained at this time comprising accompanying body.Optionally, disposable before photography composition The profile information (or exporting by the prime module of photography composition) of all persons in image is identified and calculated, and is stored. It in this way can be when photographic subjects adjust, for example, newly-increased one is accompanied body, it is not necessary to re-recognize again and calculate the wheel for accompanying body Wide information, and the profile information of body can be accompanied to obtain new photographic subjects with this according to the profile information of stored photographic subjects Then profile information further obtains the initial composition frame of new photographic subjects.Can certainly, it is first obtained in photography composition The profile information of photographic subjects goes to identify and calculate the related profile information for accompanying body when needed again；The present embodiment uses The former mode.

The present embodiment adjusts photographic subjects by dynamic in the scene that personage is intensive, to adaptively realize that number is not true Fixed, the uncertain composition of movement.The patterning process of the present embodiment be although be described with photographic subjects for personage, it is apparent that Also being suitble to photographic subjects is that animal, plant or building etc. have the object of clear profile, method be it is general, no longer repeat.

In another embodiment of the present invention, as shown in Fig. 2, a kind of automatic photography patterning process, comprising:

The profile information of step S100 acquisition photographic subjects.

Step S210 establishes the external envelope frame of photographic subjects according to the profile information.

The profile information is human body profile information, and the human body contour outline information includes that the head frame of the photographic subjects is sat Mark, body frame coordinate and each body joint point coordinate.According to the external envelope frame that the profile information establishes photographic subjects include: take it is described The minimum value of the head frame coordinates of photographic subjects, body frame coordinate and the x coordinate value in each body joint point coordinate is as left side x coordinate Value；Take the maximum value of the x coordinate value in head frame coordinate, body frame coordinate and each body joint point coordinate of the photographic subjects as right Side x coordinate value；Take the head frame coordinate of the photographic subjects, the minimum of body frame coordinate and the y-coordinate value in each body joint point coordinate Value is used as following y-coordinate value；Take the y-coordinate in head frame coordinate, body frame coordinate and each body joint point coordinate of the photographic subjects The maximum value of value is as top y-coordinate value；According to the left side x coordinate value, the right x coordinate value, the following y-coordinate value Top left co-ordinate and bottom right angular coordinate are obtained with the top y-coordinate value, it is true according to the top left co-ordinate and bottom right angular coordinate The external envelope frame of the fixed photographic subjects；Or, according to the left side x coordinate value, the right x coordinate value, the following y-coordinate Value and the top y-coordinate value obtain lower-left angular coordinate and upper right angular coordinate, according to the lower-left angular coordinate and upper right angular coordinate Determine the external envelope frame of the photographic subjects.

Step S220 generates initial composition frame according to the external envelope frame, and the initial composition frame includes the external envelope Frame, and concentrically with the external envelope frame.

Specifically, obtain the profile information of photographic subjects before starting composition, for example, the upper left point coordinate of head frame and Lower-right most point coordinate, Body frame upper left point coordinate and lower-right most point coordinate, each artis coordinate；According to the seat of the above each point Mark obtains the external envelope frame of photographic subjects (using rectangle frame, abbreviation figure frame).Specifically, taking all each point x coordinates most Small value is used as left side x coordinate value x_min, the maximum value of all each point x coordinates is taken to be used as the right x coordinate value x_max, take all each point y The minimum value of coordinate is as following y-coordinate value y_min, take the maximum value of all each point y-coordinates as top y-coordinate value y_max, thus The top left co-ordinate for obtaining figure frame is (x_min, y_max), bottom right angular coordinate is (x_max, y_min), lower-left angular coordinate is (x_min, y_min), upper right angular coordinate is (x_max, y_max), figure frame can be determined according to top left co-ordinate and bottom right angular coordinate, it can also be with Figure frame is determined according to lower-left angular coordinate and upper right angular coordinate.As an example, as shown in fig. 6, the figure frame 2 has been It is whole surround the head of personage, body, artis minimum rectangle frame.Optionally, it is required according to photography, for example, need to only shoot people The upper part of the body of object can intercept the upper half from the external envelope frame if the external envelope frame of an overall profile information has been established It is allocated as the external envelope frame for needs.

Take the center of external envelope frame as the center of initial composition frame, then obtains a complete packet by preset photography the ratio of width to height Rectangle frame (i.e. initial composition frame) containing the external envelope frame.

Specifically, for example, with constant (height of the height of i.e. initial composition frame equal to external envelope frame of the height of external envelope frame Degree), according to preset photography the ratio of width to height, the width of initial composition frame is calculated, if the width of the initial composition frame is more than or equal to The width of external envelope frame obtains just then by the symmetrical outreach of the corresponding side length of the width of external envelope frame to the width of initial composition frame Beginning composition frame；Otherwise, the width according to external envelope frame is constant (width that the width of i.e. initial composition frame is equal to external envelope frame), presses According to preset photography the ratio of width to height, the height of initial composition frame is calculated, the symmetrical outreach of the corresponding side length of the height of external envelope frame is arrived The height of initial composition frame, obtains initial composition frame.

Preferably, according to the width of external envelope frame and height and preset photography the ratio of width to height, width accounting is calculated separately With height accounting；Compare the size of width accounting and height accounting；When height accounting is greater than width accounting, according to external envelope frame Height and described photography the ratio of width to height calculate the width of initial composition frame, and keep external envelope frame height it is constant, by external envelope frame The symmetrical outreach of width arrive the width of initial composition frame, obtained rectangle frame is initial composition frame；When the height accounting is little When the width accounting, the height of initial composition frame is calculated according to the width of external envelope frame and described photography the ratio of width to height, and protect The width for holding external envelope frame is constant, and by the height of the symmetrical outreach of the height of external envelope frame to initial composition frame, obtained rectangle frame is Initial composition frame.Example is highly 0.8, preset photography the ratio of width to height is 3:2 if the width of an external envelope frame is 0.4 (showing that camera is imaged according to 3:2), calculating width accounting (the ratio between corresponding width) is 0.1333 (=0.4/3), is highly accounted for It is 0.4 (=0.8/2) than (the ratio between corresponding height), wherein height accounting is greater than width accounting, to guarantee in external envelope frame Content is not cut out, thus selection external envelope frame height remain unchanged, calculate initial composition frame width be equal to 1.2 (= 0.8/2*3), the width for obtaining initial composition frame is 1.2, is highly 0.8；By the symmetrical outreach of the width of external envelope frame to initial composition The width of frame, obtained rectangle frame are initial composition frame.

Whether step S510 accompanies body must be also as bat when accompanying body there are one in the initial composition frame described in judgement Take the photograph target；

For step S520 when accompanying body there are at least two in the initial composition frame, whether judgement each accompanies body necessary respectively Also photographic subjects are used as；

Each accompany body whether must be also as follows as the judgment step of photographic subjects:

The overlapping area of body Yu the initial composition frame is accompanied described in calculating, and is calculated the overlapping area and accounted for and described accompany body The ratio of entire area；

Judge whether the ratio is greater than or equal to preset value；It is described to accompany when the ratio is greater than or equal to preset value Body must also be used as photographic subjects；It is described to accompany body not as photographic subjects when the ratio is less than preset value.

Step S530 judges whether there is one and accompanies body that must also be used as photographic subjects.

Specifically, when in initial composition frame there are it is multiple accompany body when, accompany body to judge respectively to each, which accompany body not as Photographic subjects, which must also be used as photographic subjects.According to each judging result for accompanying body, judges whether there is one and accompany body must Photographic subjects must be also used as.

Each accompany body judgment method be it is identical, are as follows: calculate and accompany the overlapping area of body Yu initial composition frame, and calculate this Area accounts for the ratio for accompanying the entire area of body.When the ratio is greater than or equal to preset value, then this accompanies body must be also as shooting Target；Otherwise, this accompanies body not as photographic subjects.As shown in fig. 7, the figure on the left side be accompany body must also as photographic subjects one A example, the figure on the right are an examples for accompanying body not as photographic subjects.

Step S610, which exists in the initial composition frame, accompanies body, and all when accompanying body all not as photographic subjects, mobile The initial composition frame accompanies the smallest composition frame of body disturbance degree as target pattern frame to obtain, and exports the target pattern Frame.

Accompany body specifically, existing in the initial composition frame, and all when accompanying body all not as photographic subjects, it is mobile primary or Repeatedly initial composition frame regenerates several new composition frames, and selection accompanies body to influence from obtained new composition frame and initial composition frame The smallest effective composition frame is spent to export as target pattern frame.Effective composition frame is the composition of the external envelope frame comprising photographic subjects Frame.

One or more combination can be selected to attempt to translate initial composition frame from up, down, left and right four directions.Further Ground can be moved up or down when the height of initial composition frame is greater than the height of external envelope frame.When initial composition frame Width be greater than external envelope frame width when, can be moved to the left or right.Further, according to accompanying body and photographic subjects Relative positional relationship select suitable moving direction, it is preferable that accompany the direction of body to move initial composition frame along this is removed, than Such as, as shown in figure 8, accompanying body on the right of initial composition frame, towards left direction movement.

Optionally, when only one accompanies body in initial composition frame, body is accompanied to be set as with reference to accompanying body this.When initial composition frame Inside have multiple when accompanying body, selects one body is accompanied to be set as with reference to accompanying body.The direction of body is accompanied to move one by default stepping along reference is removed Secondary initial composition frame obtains a new composition frame.Judge that the whether effective composition frame of new composition frame (completely includes photographic subjects The composition frame of external envelope frame).If not effective composition frame, then exported initial composition frame as target pattern frame.If it is Effective composition frame, then further calculate the new composition frame accompanies body disturbance degree, and accompanies body disturbance degree to carry out with initial composition frame Compare.If accompanying body disturbance degree smaller, exported the new composition frame as target pattern frame.

By judging whether new composition frame is effective composition frame, it ensure that the target pattern frame of output must be effective composition Frame is not in cut hand, cut situations such as foot.

Further, it by multiple continuous translation, obtains certain direction and accompanies the smallest effective composition frame of body disturbance degree, and made For the output of target pattern frame.Specifically, for example, when only one accompanies body in initial composition frame, body is accompanied to be set as with reference to accompanying this Body.When have in initial composition frame it is multiple accompany body when, select one body is accompanied to be set as with reference to accompanying body.Along remove with reference to accompany the direction of body by The default mobile primary initial composition frame of stepping, obtains first new composition frame.When first new composition frame be effective composition frame, and Body disturbance degree more hour is accompanied, then continues to move along former direction, obtains second new composition frame, judge accompanying for second new composition frame Body disturbance degree and validity, are so repeated continuously, until the obtained new composition frame of n-th accompanies body disturbance degree greater than previous Or the new composition frame of n-th be not effective composition frame.It is exported using N-1 new composition frames as target pattern frame.By above-mentioned Mode accompanies the smallest effective composition frame of body disturbance degree on some available direction, further reduced the shadow for accompanying body disturbance degree It rings, improves patterning quality.

Further, when in initial composition frame there are it is multiple accompany body when, select one to accompany body as with reference to accompanying body, along removing ginseng It examines and the direction of body is accompanied persistently to move initial composition frame, accompany the smallest effective structure of body disturbance degree in this direction according to preceding method acquisition Picture frame is denoted as a candidate composition frame；It selects another to accompany body as with reference to body is accompanied, repeats the above method, it is right to obtain another The candidate composition frame answered；In this way, obtaining each candidate composition frame for accompanying body to remove direction, then therefrom selection accompanies body disturbance degree minimum Candidate composition frame as target pattern frame export.For example two accompanied body (to accompany and body 1 and accompany body 2, accompany body 1 on the right side of photographic subjects Side accompanies body 2 on the left side of photographic subjects), according to the above method, accompany direction (i.e. to the left side) continuous translation of body 1 initial along removing Composition frame, acquisition accompany the smallest effective composition frame of body disturbance degree in this direction, are denoted as candidate composition frame 1.Again according to the above method, edge The initial composition frame of direction (i.e. to the right) continuous translation for accompanying body 2 is removed, acquisition accompanies body disturbance degree the smallest effectively in this direction Composition frame, as candidate composition frame 2.That compares candidate composition frame 1 and candidate composition frame 2 accompanies body disturbance degree, and therefrom body is accompanied in selection The smallest composition frame of disturbance degree is exported as target pattern frame, in this way, further reduced the influence for accompanying body disturbance degree, is improved Patterning quality.

Assessment accompanies the factor of body disturbance degree to include composition frame and accompany the overlapping area of body, and/or have with composition frame overlapping Accompany body quantity.For example, accompanying body disturbance degree with the overlapping area assessment of body is accompanied according to composition frame, then overlapping area is smaller, accompanies body shadow Loudness is lower；Overlapping area is 0, and accompanying body disturbance degree is 0, so selecting composition frame and accompanying the smallest composition of the overlapping area of body Frame.For another example, overlapping body quantity and composition frame are accompanied and accompanies the overlapping area of body to assess body is accompanied to influence according to having with composition frame Degree, further, can preferentially accompany body quantity few, accompany under body quantity preferential composition frame identical and accompany the overlapping area of body the smallest Composition frame.
