Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to facilitate understanding of the technical scheme of the present invention, application scenarios of the present invention are briefly described herein:
due to the popularization of smart home, various electronic products may be equipped with cameras, such as mobile phones, notebooks, monitors, smart watches, and other smart wearable devices. In practice, users often cannot realize maximum utilization of resources for the cameras, and often use a single handheld device, which results in waste of resources of the cameras.
As shown in fig. 1, it is assumed that a notebook, a television, a mobile phone and a monitor are disposed in a room, wherein each of the notebook, the television and the monitor includes one camera, and the mobile phone includes a front camera and a rear camera, i.e. five cameras in total in the room. When a person sits on the sofa and uses the mobile phone placed on the table to carry out video call, the user can only stay in the area A to bring inconvenience to the activities of the user if the user wants to keep the mirror under the conditions of not holding the mobile phone and not manually adjusting the mobile phone to the rear camera.
In addition, even when shooting at different angles by using a plurality of cameras during a video conference or video live broadcast, if a plurality of persons are simultaneously in a video conference scene, a situation that one or two persons cannot go out of the mirror may still occur due to a shooting blind area.
The invention aims to provide a shooting scheme which is used for realizing the switching of final display pictures based on the acquired pictures of two or more cameras, so that not only can random activities in the coverage areas of all cameras in the single-person video call process be realized, but also the complete display of all concerned objects in a multi-person video conference can be realized as far as possible.
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
Referring to fig. 1 and fig. 2 in combination, an embodiment of the present invention provides a photographing method, including:
s1, acquiring shooting pictures acquired by at least two cameras;
s2, identifying shooting pictures based on a preset display target, and extracting shooting pictures containing the display target as preselected pictures;
s3, determining a picture to be displayed from the preselected pictures.
It is assumed that a notebook, a television, a mobile phone and monitoring are arranged in a room, wherein the notebook, the television and the monitoring respectively comprise a camera, and the mobile phone comprises a front camera and a rear camera, namely five cameras in total in the room.
Based on the steps S1-S3, firstly, uploading shooting pictures acquired by all cameras to a cloud end, identifying the uploaded shooting pictures based on preset display target analysis, judging whether each shooting picture contains a display target or not, and extracting the shooting pictures containing the display target as preselected pictures. And finally, determining a picture to be displayed from the preselected pictures, and using the picture to be displayed for returning for use so as to carry out final display.
It will be appreciated that the display targets may be one or at least two; when the display target is one, only the shot picture including the display target is selected as the preselected picture.
As shown in fig. 3, in step S2, when at least two display targets are included in the photographed images acquired by the plurality of cameras, the determination of the image to be displayed is achieved by:
s21, calculating an effective picture index of each preselected picture;
s22, comparing the effective picture indexes, and determining a preselected picture corresponding to the effective picture index with the largest value as a picture to be displayed.
When the display target is one, the effective picture index is a unit display index of the display target; when the display targets are at least two, the effective picture index is the sum of unit display indexes of all the display targets. It will be appreciated that the display target may be a person in the captured image, or may be an animal, plant or other furnishing. In addition, when the display target is a human example, a plurality of persons may appear in the photographed image, but the display target may be a specific one or a plurality of the display targets.
In one of the alternative implementations of this embodiment, the unit display index is a display index of a parameter, such as a ratio parameter of the display target to the photographed image, a tilt parameter of the display target relative to the camera, or a distance parameter between the display target and the camera.
In another optional implementation manner of this embodiment, the unit display index is a weighted sum value obtained by respectively assigning a weight coefficient to the display index of each parameter, among the display indexes of the two or more parameters; for example, a weight coefficient is respectively assigned to a proportion parameter of the display target occupying the photographed picture, an inclination parameter of the display target relative to the camera, and a distance parameter between the display target and the camera, and then a unit display index is obtained by weighted summation.
It will be appreciated that the display index of the parameter may also be increased or decreased depending on the point of interest of the display effect.
Assuming that the display target is a person, the following will briefly describe the calculation of the unit display index, taking as an example the scale parameter of the display target occupying the photographed image and the tilt parameter of the display target with respect to the camera:
in this embodiment, the proportion parameter of the display target to the photographed image is calculated in a data manner. For example, the camera is currently a million pixels S1, then in the photographed picture, the display target occupies a hundred thousand pixels S2, and then the display target occupies a proportion parameter p1=s2/s1=30% of the photographed picture.
The tilt parameter of the display object with respect to the camera can also be understood as the tilt of the face with respect to the camera. The tilt parameters of the display object relative to the camera can be calculated as follows: and calculating the ratio of the current value of the facial feature number of the display target to the total facial feature number of the display target in the shooting picture.
Specifically, the face recognition technology can be assisted to realize calculation of the inclination parameters of the display target relative to the camera. For example, the face recognition system acquires 20 total facial features N1 of the display targets, and only the current value N2 of the facial features N of 13 display targets is shot in the image, so that the tilt parameter p2=n2/n1=65% of the display targets relative to the camera is obtained.
As shown in fig. 7, when the display target a is located in the area 4, the photographed images collected by the television camera and the monitoring camera are all capable of encompassing the display target. When the display target A is positioned at the illustrated position and faces the direction indicated by the arrow, the proportion parameter of the display target A to the shot picture is about 20%, and the current value of the facial feature number of the display target is 5; therefore, effective display index R for television camera Television set The method comprises the following steps:
R television set ＝20％*0.5+5/20*0.5＝22.5％。
For the monitoring picture, the display target occupies about 20% of the proportion parameter of the shooting picture, and the current value of the facial feature number of the display target is 15; therefore, the effective display index R for the monitor screen Monitoring The method comprises the following steps:
R monitoring ＝20％*0.5+15/20*0.5＝47.5％。
Since 47.5% is higher than 22.5%, the display effect of the monitoring is better than that of the television camera, and therefore the shooting picture collected by the monitoring is taken as the picture to be displayed.
In this embodiment, the total number of facial features of the display target is a preset value, and different users may be identified and pre-stored in advance by using a face recognition system. In addition, the total number of the facial features of the display target can be the maximum value of the facial feature number of the display target in the historical shooting pictures acquired by each camera, and when the display target is a new user which does not realize the input of information, the facial features of the display target can be continuously supplemented and perfected in the shooting process of each camera, so that the calculation of the inclination parameters of the new user relative to the cameras can be performed under the condition that the information is not pre-stored.
Then, a weight coefficient W1 is given to a proportion parameter of the display target occupying the shooting picture, and a weight coefficient W2 is given to an inclination parameter of the display target relative to the camera; it is understood that the values of W1 and W2 may be adjusted according to actual situations, for example, if the proportion of the attention person to the screen is compared, W1 may be larger than W2. In this embodiment, taking W1 and W2 as examples, the effective picture index is calculated as follows: the effective picture index r=p1×w1+p2×w2=47.5%.
Based on the foregoing steps, the present embodiment provides a shooting method, by calculating a dynamic effective picture index, a picture to be displayed with a display effect more in line with actual requirements can be flexibly selected from a plurality of preselected pictures, and it can be ensured that a display object can be displayed in the picture with the expected display distance, angle, duty ratio and other effects, so that the shooting method can be suitable for various application scenarios, such as video conferences, video live broadcasting, stage direct shooting and moving mirrors, and the like.
Further, in the video conference, the video live broadcast, the stage direct shooting and transporting mirror and the like, at least two display targets may be displayed; at this time, when calculating the effective screen index of each photographed screen, the unit display indexes R of all the display targets are summed up.
Specifically, at least one of the display targets may be selected as a primary target, and the others as secondary targets; and respectively calculating unit display indexes of the main target and the secondary target, respectively giving weight coefficients to the unit display indexes of the main target and the secondary target, and then calculating a weighted sum value. The main target is preferentially displayed by distributing the weight coefficient according to the importance degree of the display target.
It will be appreciated that there is a possibility that at least one display object is omitted in each shot, but the parameters of the other display objects have a higher display index, so that the shot still has a higher effective image index. At this time, if the frame to be displayed is determined simply according to the effective frame index, some display targets of the final display frame will be lost.
Referring to fig. 4 to fig. 6 in combination, in order to further ensure that all the display objects can be displayed in the final display screen, step S2 further includes the following steps:
s23, judging whether the picture to be displayed comprises all display targets, if so, executing a step S24; if not, executing step S25;
s24, keeping the picture to be displayed unchanged;
s25, sequentially identifying whether the corresponding preselected pictures comprise all the display targets according to the order of the effective picture indexes from large to small, and determining the preselected pictures comprising all the display targets as pictures to be displayed when the preselected pictures comprising all the display targets are identified.
Based on steps S23 to S25, omission of the display target in the final display screen can be avoided.
Based on the foregoing steps, after determining the frame to be displayed and before performing the feedback display, detecting whether the display target is missed in the frame to be displayed, specifically, detecting by using the unit display index value of each display target, and if the value of a certain unit display index is 0, determining that the missed display target exists in the frame to be displayed.
In this case, whether or not each of the preselected pictures has missing display targets may be sequentially determined in order from large to small based on the unit display indexes of each of the display targets until a preselected picture is found, in which the unit display index of each of the display targets is not zero, and the preselected picture including all the display targets is determined as the picture to be displayed.
It is to be understood that, when none of the shot images includes all the display targets, the shot image having the largest number of the included display targets may be determined as the image to be displayed, so that more display targets are displayed as much as possible.
The number of the shooting pictures with the largest target number can be one or a plurality of shooting pictures in parallel. For example, assuming that the display targets are six, two of five shot images acquired by the five cameras include three display targets, and the remaining shot images include five display targets, three shot images including five display targets are selected as the preselected images in this step.
In addition, when the preselected screen including all the display targets is not recognized in step S25, in order to achieve complete display of the entire display targets as much as possible, the photographing method further includes the steps of:
s41, keeping the picture to be displayed unchanged;
s42, taking a display target which is not displayed in the picture to be displayed as an additional display object;
s43, sequentially identifying the preselected pictures based on the additional display objects according to the order of the effective picture indexes from large to small until the preselected pictures containing the additional display objects are identified, and determining the preselected pictures containing the additional display objects as additional pictures;
and S44, adding the additional picture to a background area in the picture to be displayed.
Based on steps S41 to S44, the display target that is not originally displayed in the screen to be displayed can be additionally displayed. It is understood that the background area in step S44 is an unmanned area in the screen, so as to avoid shielding other display objects.
As shown in fig. 7, if the display target is three persons in the figure, two persons are only located in the shooting areas of the television camera and the monitoring camera, and the other person can be shot by the television camera and the monitoring camera at the same time, but the shooting pictures of none of the cameras can include three persons at the same time.
In this embodiment, the shooting picture including the most displayed target objects may be selected as the preselected picture first, in this example, the shooting pictures respectively acquired by the television camera and the monitoring camera; and then, respectively calculating the effective display indexes of the two shooting pictures, and extracting the shooting pictures acquired by the television camera as pictures to be displayed according to the result. The picture to be displayed with the highest effective index determined before can also be directly used.
Further, as shown in fig. 8, a display target which is not displayed in the to-be-displayed picture is taken as an additional display object, a shooting picture acquired by a monitoring camera which includes the additional display object is extracted as an additional picture, and the additional picture is added to a background area in the to-be-displayed picture to form a final display picture.
In this embodiment, the effective display index is calculated in real time according to the captured images acquired by each camera, and the captured image corresponding to the effective display index with the highest numerical value is selected for display at each moment according to the result, so that the camera with the best display effect can be flexibly and in real time selected as the video source, thereby ensuring the display effect.
Based on the shooting method provided by each embodiment, two or more cameras can be reasonably applied, so that the situation that camera resources are empty is avoided; meanwhile, the camera with the best display effect can be selected as a video source, meanwhile, the camera does not need to be manually switched, high-quality picture display can be efficiently and conveniently realized, the user experience is effectively improved, and the shooting function of videos is enriched.

judging whether shooting pictures containing all display targets exist or not; extracting shooting pictures containing all display targets as preselected pictures; and extracting the shot picture with the largest number of the included display targets as a preselected picture. Accordingly, it is possible to avoid missing the display target in the final display screen. When none of the photographed pictures contains all of the display targets, the photographed picture with the largest number of the contained display targets is extracted as a preselected picture to display as many display targets as possible.
The number of the shooting pictures with the largest target number may be one or a plurality of shooting pictures in parallel. For example, assuming that the display targets are six, two of five shot images acquired by the five cameras include three display targets, and the remaining shot images include five display targets, three shot images including five display targets are selected as the preselected images in this step.
