Referring to fig. 1, the method flow of the intelligent control method for television playing includes the following steps:
step S100: and acquiring a real-time area picture of a preset visual area.
The visual area is an area which is set in advance by a worker and is positioned in front of the television and can be used for watching pictures of the television, and the real-time area picture is an image picture acquired in front of the television and is acquired by a camera arranged on the television.
Step S101: and determining the picture watching personnel in the real-time area picture.
The specific determination method is described below, and details are not described here.
Step S102: and determining a favorite type label corresponding to the picture viewer according to the preset type matching relation.
The favorite type labels are favorite television content labels of people watching television pictures, such as love, suspicion, children and the like, different people correspond to different favorite type labels, the type matching relationship between the favorite type labels can be determined through the type watched by the people under the history, and when the people do not watch the television under the history, the favorite type labels are absent.
Step S103: and acquiring a channel type label of a preset playable channel at the current time point.
The playable channel is a channel capable of playing the picture content in the television, and the type label of the channel is a label of the content played at the current time point.
Step S104: and defining the playable channels with the channel type labels consistent with the favorite type labels as favorite channels, determining a channel playing catalog according to all the favorite channels, and controlling the television to switch channels according to the channel playing catalog when switching channels.
Different channels can be distinguished by defining favorite channels, and the channel playing catalog is a catalog formed by combining all favorite channels, and the catalog is arranged according to the serial numbers of each channel, so that when the channels of the television are switched, the user can only switch among the favorite channels, thereby reducing the occurrence of invalid switching of the user and improving the overall experience effect of the user using the television.
Referring to fig. 2, the step of determining a picture viewer in a real-time area picture includes:
step S200: and determining eye characteristics and acquiring eye positions of the person according to a preset characteristic determination algorithm in the real-time area picture.
The eye features are features similar to human eyes in the determined real-time region picture, the feature determining algorithm can be a convolutional neural network algorithm, and the images can be processed through the feature determining algorithm; the eye position of the person is the determined eye position characteristic of the pixel position in the image frame.
Step S201: a calculation is performed to determine the eye separation distance based on any two person eye positions.
The eye distance is a distance value between two eye positions of a person, the distance value is a distance value between two eye positions of the person in an actual space condition, the distance value can be calculated and determined through the pixel condition and the distance between two eye features in a picture, and the calculation method is a conventional technical means of a person skilled in the art and is not repeated.
Step S202: whether an eye separation distance smaller than a preset reference distance exists is judged from the single eye characteristic.
The reference distance is a maximum distance value between two eye features when the two eye features are determined to be on the same person, which is set by a worker, and the purpose of judgment is to know whether the determined eye features exist independently.
Step S2021: if there is no eye separation distance less than the reference distance, the eye feature is defined as an invalid feature.
When there is no eye separation distance less than the reference distance, the eye feature is indicated to exist independently, and the user of the eye feature does not have the possibility of watching the television basically, and the eye feature is defined as an invalid feature to be identified, so that the distinction of different eye features is realized.
Step S2022: if there is an eye separation distance smaller than the reference distance, two eye features corresponding to the eye separation distance are mutually defined as binding features.
When the eye separation distance smaller than the reference distance exists, the eye characteristics are matched, namely the two characteristics are eyes of a person, and the two characteristics are mutually defined as binding characteristics at the moment so as to realize the distinction of other eye characteristics and facilitate the subsequent analysis.
Step S203: and carrying out facial feature recognition according to the eye features which are binding features to determine the picture watching personnel.
At the moment, only people with two eye features are subjected to face feature recognition, so that people who do not watch television do not need to be subjected to face recognition, and the overall determination efficiency of picture watching people is high; the face feature recognition method is a conventional technical means for those skilled in the art, and will not be described in detail.
Referring to fig. 3, after the binding feature is determined, the step of determining the picture viewer further includes:
step S300: and acquiring a position determination pixel distance and a position determination pixel angle according to the two mutually binding characteristics.
The position determining pixel distance is a distance value when the camera on the television acquires an image of the eye feature when the eye feature is determined, the distance value can be determined according to an image imaging condition, and the position determining pixel angle is an included angle between a straight line formed between the eye feature and the camera on a plane where the ground is located and a screen of the television, and referring to fig. 4.
Step S301: and determining pixel distances and pixel angles according to the positions to determine the positions of the two eye planes which are binding features.
The eye plane position is the actual position of the eye feature in a plane parallel to the ground, see fig. 4.
Step S302: connecting the two eye plane positions to determine a user face line segment, establishing a viewing ray which forms a preset viewing angle with the user face line segment at the eye plane position, and determining a viewing angle viewing area according to the two viewing rays.
The user face line segment is a line segment taking two eye plane positions as endpoints, namely, a projection line segment when the user face plane is compared with the ground, referring to fig. 4, a viewing angle is a sight line diffusion angle which can be seen by a user, a viewing ray is a marginal sight line edge line which can be observed by the user through eyes, and a viewing angle viewing area is an area which is formed by two viewing rays and the user face line segment and is provided with an opening towards one end of the television direction, wherein the area is an area in which the person can acquire pictures through the eyes.
Step S303: and determining an overlapping area according to the viewing angle viewing area and a preset screen display area, and calculating according to the overlapping area and the screen display area to determine the viewing area ratio.
The screen display area is the screen area of the television, the overlapping area is the overlapping part of the plane where the screen of the television is positioned and the viewing area of the visual angle, the ratio of the viewing area to the overlapping area to the screen display area can be determined by dividing the length of the overlapping area by the length of the screen display area.
Step S304: and judging whether the viewing area duty ratio is larger than a preset normal viewing duty ratio.
The normal viewing ratio is the minimum viewing area ratio set by the staff and used for recognizing that the user has the effect of viewing the television picture, and the purpose of judgment is to know whether the user has the effect of viewing the television.
Step S3041: if the viewing area duty ratio is larger than the normal viewing duty ratio, face feature recognition is carried out according to the eye positions of the people who are binding positions to determine the picture viewing personnel.
When the viewing area ratio is larger than the normal viewing ratio, the person is indicated to have the function of viewing the television picture, and the person is determined to be a picture viewer.
Step S3042: if the viewing area duty ratio is not greater than the normal viewing duty ratio, the person corresponding to the eye feature is not defined.
When the viewing area ratio is not larger than the normal viewing ratio, the person is not viewing the television content, and no special definition is made for the person.
Referring to fig. 5, the method further includes a step of determining a viewing angle, including:
step S400: feature recognition is performed in the ocular feature to determine the ocular feature and an ocular outer contour is determined from the ocular feature.
The eyeball characteristic is the eyeball part in the determined ocular characteristic, the characteristic recognition method can be consistent with the ocular characteristic determination method, the ocular external contour is the external contour line of the ocular characteristic, and refer to fig. 6.
Step S401: points on the outer contour of the eye are interconnected to determine the point spacing distance.
The point spacing distance is the distance value between any two points on the external contour of the eye.
Step S402: and determining the point position interval distance with the maximum value according to a preset ordering rule, and defining points on the two eye external contours corresponding to the point position interval distance as boundary points.
The sorting rule is a method which is set by staff and can sort the numerical values, such as an bubbling method, and two points which are farthest from the external outline of the eye, namely two corner positions of the eye, can be determined through the sorting rule, and the points are defined as boundary points for identification at the moment so as to facilitate subsequent analysis.
Step S403: and establishing an eye width axis according to the two boundary points, defining an intersection point of the external contour of the eyeball characteristic and the eye width axis as a critical intersection point, and acquiring critical coordinate values of the two critical intersection points.
The eye width axis is a straight line coordinate axis penetrating through the two boundary points, the origin of the coordinate axis can be any boundary point, the division condition of the eyeball on the eye can be obtained by defining a critical intersection point, and the critical coordinate value is the coordinate value of the critical intersection point on the eye width axis.
Step S404: and determining the eye width axis and the viewing angles corresponding to the two critical coordinate values according to a preset angle matching relation.
Different eye width axis widths and eyeball sizes indicate different sight conditions of a user, and the deviation condition of the eyeballs on the eyes can be obtained according to two critical coordinate values, so that the watching included angle of the eyes can be determined; for example, when the eyeball is left, a screen to be viewed by the user is described as a left screen, and the viewing angle should be set.
Referring to fig. 7, after the determination of the picture viewer, the intelligent control method for playing the television further includes:
step S500: and judging whether the picture watching staff are all in a preset registered staff set.
The registered personnel set is a set formed by combining personnel watching the television in the history process and recording favorite watching types, and the purpose of judgment is to know that the corresponding channel can be determined according to the personnel.
Step S5001: if the picture viewers are not in the registered person set, the television is controlled to switch channels according to the preset fixed play list when the channels are switched.
When the picture viewers are not in the registered personnel set, a new person is indicated, and the user may get home to make a guest at the moment, and the channel switching is performed by using the set fixed play directory, wherein the fixed play directory is a directory set in advance by the staff, and generally comprises all types of channels, namely, the channel switching is not performed with redundant processing, and the corresponding switching is performed according to the serial number of the channel.
Step S5002: if the picture viewing staff are all in the registered staff set, counting is carried out according to the picture viewing staff to determine the number of the viewing staff.
When the picture viewers are in the registered personnel set, the channel switching condition can be determined by describing the type expression which the viewers like to watch; the number of the viewers is the total number of the currently determined picture viewers, and can be obtained by counting the picture viewers one by one.
Step S501: it is determined whether the number of viewers is one.
The purpose of the judgment is to know whether only the favorite type of a person needs to be considered.
Step S5011: if the number of the viewers is one, determining the favorite type label according to the viewers on the picture, and determining the channel playing catalog.
When the number of the watching staff is one, only one person is shown to watch the television, and at the moment, the corresponding switching is carried out according to the favorite channels of the person.
Step S5012: if the number of the viewers is not one, determining the favorite type tags according to the viewers of each picture, and performing intersection calculation according to the determined favorite type tags to determine the common type tags.
When the number of the watching staff is not one, the condition that a plurality of television watching staff exist is indicated, and at the moment, the favorite types of each staff are inconsistent possibly, and further analysis is needed; the common type tag is a type tag of a channel which is loved by each picture viewer, for example, A, B, C three picture viewers, wherein A loves love and suspicion, B loves love and cartoon, C loves love and suspicion, the common type tag is love, and when the three have no common tag, the common type tag is empty.
Step S502: and determining favorite channels according to the common type label when the common type label is not empty, and determining a channel play list.
When the common type label is not empty, the picture viewers are indicated to have the common favorite type, and the corresponding channel is determined according to the type.
Referring to fig. 8, when the common type tag is empty, the intelligent control method for playing the television further includes:
step S600: and establishing a detection interval with the width of a preset fixed duration on a preset time axis, and enabling the rear end point of the detection interval to coincide with the current time point.
When the common type label is empty, the picture viewers are not commonly favored, and further analysis is needed; the time axis is a coordinate axis formed by combining time points, the coordinate axis can be arranged forwards or backwards, the fixed time length is a fixed time length which is set by a worker and can be used for acquiring data of historical viewing conditions of a user, and the detection interval is established, so that the historical viewing data of the user can be conveniently acquired, and the subsequent analysis is facilitated.
Step S601: and combining all current picture viewers to determine a requirement person combination, and acquiring a playing type label under the condition that the requirement person combination corresponds to in a detection interval.
The above example is described with respect to a combination of all picture viewers, namely ABC, a playback type tag being a tag of a channel that is played when the combination is used to view a television in a detection zone, and being empty when the combination is not present in the history to view the television.
Step S602: and when the play type label is not empty, counting according to the determination condition of the play type label to determine the combination determination times, and counting according to each play type label to determine the label times.
When the play type label is not empty, the situation that the combination personnel watch the television together in the history situation is described, at this time, the situation of the played different types of channels can be counted to determine the combination determination number, that is, the total number of times of watching under all types of channels, the label number, that is, the total number of times of watching under the corresponding types of channels, for example, the number of times of loving labels is 10, the number of times of suspicion labels is 20, the number of times of cartoon labels is 30, and the combination determination number is 60.
Step S603: and calculating according to the number of tags and the combination determination number to determine the type occupation value.
The above examples illustrate that the type ratio is the ratio of each type of channel to all types of channels, the love type ratio is 1/6, the suspicion type ratio is 1/3, and the cartoon type ratio is 1/2.
Step S604: and determining the type occupation value with the largest value according to the ordering rule, and determining the channel playing catalogue according to the playing type label of the type occupation value.
The type with the largest occurrence number can be determined through the ordering rule, so that the catalog determination is carried out according to the type, and the switching of the subsequent channels is facilitated.
Referring to fig. 9, when the play type tag is empty, the intelligent control method for playing the television further includes:
step S700: and combining all current picture viewers in pairs to determine a comparison person combination, acquiring a channel type label which appears the most times under the condition that the comparison person combination corresponds to in a detection interval, and defining the channel type label as a priority label.
The comparison staff combination is a combination formed by two picture viewers, and the comparison staff combination has three groups of AB, BC and AC, so that the most channel tags can be determined under each combination when each combination is watched under the history condition, and the tags are defined as priority tags to realize the differentiation of different channel type tags, wherein the priority tags are empty when the two are not watched together.
Step S701: and determining the personnel priority in the comparison personnel combination according to the priority label and the favorite type label of each personnel.
