Or when a plurality of pictures to be recognized are collected, the pictures to be recognized may also be collected within a preset time period based on a preset number, where the preset number may be flexibly set according to actual needs, for example, 20 or 40 pictures may be collected, and in one example, if the preset time period is 60 minutes and the preset number is 100, 100 pictures to be recognized are collected within 60 minutes.
In some embodiments, step S11 includes: the video playing device collects a plurality of pictures to be identified through the camera in a preset time period. That is to say, video playback device includes the camera, in the time quantum that predetermines, gathers a plurality of pictures of waiting to discern through the camera.
In some embodiments, step S11 includes: and receiving a plurality of pictures to be identified, which are sent by a target terminal and collected within a preset time period. That is to say, the picture to be recognized is collected by the target terminal, and for the target terminal, the picture to be recognized may be flexibly set according to actual needs, and in one example, the picture to be recognized may be set as a terminal that is placed in the same environment as the video playing device and carries a camera, so that the target terminal may collect the picture of the environment where the video playing device is located, and use the picture as the picture to be recognized.
In this embodiment, the video playing device may obtain a plurality of pictures to be identified collected within a preset time period during the startup process; or in the operation process after the start-up, a plurality of pictures to be identified collected in the preset time period may be obtained according to the preset rule, for example, a plurality of pictures to be identified collected in the preset time period may be obtained in real time.
Step S12: and judging whether the service object is a target object or not according to the picture to be identified.
In this embodiment, the target object may be flexibly set according to actual needs.
In some embodiments, the target object may be a person, so that a video can be played for a person to watch without human operation, and convenience is provided to the person in the case where the person is inconvenient to operate the video playing device (for example, when there is something on the hand).
With the aging of the population and the increase of the number of the single population, the pet becomes one of the most important companions of the modern population, and in some cases, the user can play videos for the pet to watch so as to attract the attention of the pet, avoid uneasiness, family dismantling and the like of the pet and enable the animal to be more classified. Considering the problem that the user is worried about because the pet cannot watch the video when the user is not near the pet due to work or the like, the target object may be an animal in some embodiments.
In this embodiment, after the picture to be recognized is obtained, whether a service object of the video playing device is a target object is determined according to the picture to be recognized. The picture to be identified can be identified based on an image identification technology so as to judge whether the service object is a target object.
Step S13: if so, playing the target video for the target object to watch.
In this embodiment, after the service object is determined to be the target object, the target video is played for the target object to watch.
The embodiment provides a video playing method, which comprises the following steps: acquiring a plurality of pictures to be identified collected in a preset time period, and judging whether a service object is a target object or not according to the pictures to be identified; if so, the target video is played for the target object to watch, that is, in this embodiment, a new video playing method is provided, and the video can be played for the target object to watch without the target object operation, so that convenience is provided for the target object which is inconvenient to operate or the target object which does not know how to operate the video playing device, and user experience is improved.
Based on the first embodiment, a second embodiment of the video playing method of the present invention is provided. In this embodiment, the target object is an animal, and step S12 includes: and judging whether animals exist in the picture to be identified and people do not exist in the picture to be identified.
That is to say, in this embodiment, it is determined whether the service object of the video playback device is an animal by determining whether an animal exists in the picture to be recognized and no person exists in the picture to be recognized. If the animal exists in the picture to be recognized and the person does not exist (namely, the person does not exist in all the pictures to be recognized and the animal exists in at least one picture to be recognized), the situation that the animal exists in the environment where the video playing device is located is indicated, the owner of the animal is not beside the animal, and the service object of the video playing device is the animal; if at least one picture has a character in the pictures to be identified, the service object of the video playing device is the character, and the service object of the video playing device is not an animal; and if all the pictures to be identified do not have animals or human beings, the video playing device does not have a service object.
In this embodiment, whether a person exists in the picture to be recognized may be determined by a face recognition method or the like. And judging whether the animal exists in the picture to be identified by an animal identification method. Of course, the presence or absence of an animal or human being in the picture to be recognized can also be determined in other ways.
The embodiment provides a video playing method, which improves the accuracy of judgment by using the method when a target object is an animal. Acquiring a plurality of pictures to be identified collected within a preset time period, and judging whether animals exist in the pictures to be identified and people do not exist in the pictures to be identified so as to determine whether a service object of the video playing device is an animal or not; if so, the target video is played for the animal to watch, that is, in this embodiment, a new video playing method is provided, and the video can be played for the animal to watch under the condition that the animal owner is identified not to be around the animal any longer, so that even if the animal owner is not around the animal, the video playing device can play the video to attract the attention of the animal, so that the animal is safer, the worry of the user is reduced, and the user experience is improved.
Based on the first embodiment, a third embodiment of the video playing method of the present invention is provided. In this embodiment, referring to fig. 3, step S12 includes:
step S121: and determining the motion area of each picture to be identified.
In this embodiment, if there is a person or an animal in the current environment where the video playing device is located, because the person or the animal may move, a part of the collected multiple pictures to be identified is different, so that the motion region of each picture to be identified is determined, and then, the video playing device may identify according to the part of the motion region to determine whether the service object is an animal.
In some embodiments, step S121 comprises: and comparing the pictures to be identified to determine the motion area of each picture to be identified. That is to say, the pictures to be recognized are compared, so that different parts of the two pictures to be recognized are analyzed and used as the motion areas of the pictures to be recognized. In an example, two adjacent pictures to be recognized may be compared according to the acquisition time of each picture to be recognized to determine the motion region of each picture to be recognized, for example, assuming that 4 pictures to be recognized are acquired in total, a first picture to be recognized is compared with a second picture to be recognized to determine different portions of the first picture to be recognized and the second picture to be recognized, a portion of the first picture to be recognized, which is different from the second picture to be recognized, is taken as the motion region of the first picture, and a portion of the second picture to be recognized, which is different from the first picture to be recognized, is taken as the motion region of the second picture; comparing the second to-be-identified picture with the third to-be-identified picture, and determining a part, which is different from the second to-be-identified picture, in the third to-be-identified picture to be used as a motion area of the third to-be-identified picture; and comparing the fourth to-be-identified picture with the third to-be-identified picture, and determining a part, which is different from the third to-be-identified picture, in the fourth to-be-identified picture to be used as a motion area of the fourth to-be-identified picture.
In some embodiments, step S121 comprises: and comparing each picture to be identified with a preset reference picture to determine the motion area of each picture to be identified. That is, in this manner, the picture to be recognized is compared with the preset reference picture, so that a portion of the picture to be recognized, which is different from the preset reference picture, is determined as the motion region of the picture to be recognized. The preset reference picture may be preset, and in the environment where the video playing device is located, there is no picture of a person or an animal, and considering that the environment where the video playing device is located may be changed, the preset reference picture may be updated according to an actual situation.
Step S122: and determining the number of the target pictures in the pictures to be recognized according to the motion area.
In this embodiment, the target picture is a picture satisfying a preset condition, where a ratio of a motion region area to a picture area is set.
The preset conditions can be flexibly set according to actual needs and are used for judging whether the target object exists in the picture.
In one example, when the target object is an animal, the preset condition may be set to be smaller than the preset second ratio. The second ratio is a reasonable ratio that is preset to determine whether the motion region in the picture to be recognized is a human or an animal, and may be set to 1/3, 1/2, or the like, for example. It should be understood that the motion area is an area occupied by an animal or a human being, and the size of the human being is different from that of the animal, so that the proportion of the motion area in the picture to be recognized is different, and in order to further judge whether the animal or the human being exists in the picture to be recognized, a preset second proportion is set, when the proportion of the area occupied by the motion area in the picture to be recognized to the area of the picture is smaller than the preset second proportion, the animal exists in the picture to the greatest extent, and the picture is taken as a target picture. For example, assuming that the predetermined second ratio is 1/3, the area of a certain to-be-recognized picture is 1000 pixels, and the area occupied by the motion region is 200 pixels, since the ratio of the area of the motion region to the picture area is 1/5, which is smaller than the predetermined second ratio, the to-be-recognized picture is the target picture.
In one example, when the target object is a person, the preset condition may be set to be greater than a preset second ratio. When the ratio of the area occupied by the motion area to the area of the picture in the picture to be identified is greater than or equal to the preset second ratio, people exist in the picture to the greatest extent, and the picture is a target picture. For example, assuming that the predetermined second ratio is 1/3, if the area of a certain to-be-recognized picture is 1000 pixels and the area occupied by the motion region is 500 pixels, since the ratio of the area of the motion region to the picture area is 1/2, which is greater than the predetermined second ratio, the to-be-recognized picture is the target picture.
In this embodiment, after the motion region of each to-be-recognized picture is determined, whether each to-be-recognized picture is a target picture is determined according to the motion region and a preset condition, and then, the number of the target pictures is counted.
Step S123: and judging whether the ratio of the number of the target pictures to the number of the pictures to be recognized is larger than a preset first ratio.
The preset first ratio can be flexibly set according to actual needs, for example, set to 50%, 60%, and the like.
In this embodiment, a preset first ratio is set in consideration of the situation that power consumption is wasted when a video is played if a target object passes through an environment where a video playing device is located, and only when the ratio of the number of target pictures to the number of pictures to be recognized is greater than the preset first ratio, a service object of the video playing device is determined to be the target object. For example, assuming that the preset first ratio is 50%, the number of the pictures to be recognized is 100, and the number of the target pictures is 60, since the ratio of the number of the target pictures to the number of the pictures to be recognized is greater than the preset first ratio, it indicates that the target object often leaves the environment where the video playing device is located, and therefore, it is determined that the service object of the video playing device is the target object.
The embodiment provides a video playing method, which determines a motion region of each picture to be recognized, determines the number of target pictures in the picture to be recognized according to the motion region, and determines whether a ratio of the number of the target pictures to the number of the pictures to be recognized is greater than a preset first ratio to determine whether a service object is a target object, so that accuracy of determination is improved.
Based on the foregoing embodiments, a third embodiment of the video playing method of the present invention is provided. In this embodiment, referring to fig. 4, step S13 includes:
step S131: if yes, determining the type of the target object according to the picture to be identified.
It should be noted that after the target object is determined, the type of the target object may be further determined according to the picture to be recognized, where the dividing manner of the type of the target object may be flexibly set according to actual needs.
For example, in one example, assuming that the target object is a person, the types of target objects may include boys and girls, considering that videos of interest are different for boys and girls. Then after determining that the service object is a person, it is further determined whether the type of the target object is boy or girl based on the picture to be recognized.
In another example, assuming that the target object is a person, the type of the target object may be classified according to age considering that videos in which people in different age groups are interested are different, for example, the type of the target object may include children, middle-aged people, and elderly people. After the service object is determined to be a person, it is further determined which of a child, a middle-aged person and an elderly person the type of the target object is, based on the picture to be recognized.
In yet another example, assuming that the target object is an animal, the type of target object includes an animal breed (e.g., cat, dog, etc.) in view of the fact that different animals perceive different videos. After the service object is determined to be an animal, which breed of animal is further determined according to the picture to be identified when the target object is.
The mode for determining the type of the target object can be flexibly set according to actual needs.
In some embodiments, step S131 includes: and if so, determining the type of the target object included in the target picture based on an animal recognition technology or a face recognition technology.
In some embodiments, step S131 includes:
step S1311: if yes, extracting a motion area part from each target picture as a target sub-picture.
In this embodiment, since the motion region is a region where the target object is located, a portion corresponding to the motion region is extracted from the target picture as a target sub-picture, and it should be noted that one target picture corresponds to one target sub-picture.
Step S1312: and carrying out graying processing on the target sub-picture.
And in the process of acquiring the target sub-picture, carrying out gray processing on the target sub-picture, namely processing the target sub-picture into a gray picture. The method for carrying out graying processing on the target sub-picture can be flexibly set according to actual needs.
In some embodiments, graying the target sub-picture comprises: for each pixel of the target sub-picture, firstly summing the R (red color component), G (green color component) and B (blue color component) of the pixel according to a preset weight value, and then dividing the sum by a preset value to obtain the gray value of the pixel. That is to say, for a certain pixel point on the target sub-picture, it is assumed that the corresponding pixel value is (R, G, B), and the processed gray value is f ═ (f1 × R + f2 × G + f3 × B)/x, where the weight values f1, f2, and f3 can be flexibly set according to actual needs, and the preset value x can be flexibly set according to actual needs, in an example, the size of x is positively correlated with the area of the target sub-picture (i.e., the area of the motion region in the target picture), that is, the larger the target sub-picture is, the larger x is.
Step S1313: and determining the type of the target object according to the target sub-picture after the graying processing.
And after the target sub-picture is subjected to graying processing, determining the animal type according to the grayed target sub-picture.
In some embodiments, if the target object is an animal, determining the type of the target object according to the grayed target sub-picture includes: scanning pixels of bright and dark crossed parts in the target sub-picture after the graying processing so as to determine the positions of the eyes of the animal; determining gray scale types of the positions of the eyes of the animal, wherein the gray scale types comprise three types: uniform gray, non-uniform gray, jump gray (i.e., gray value jumps from 0 to 255, or jumps from 255 to 0); when the gray type of the animal eye position part is jump gray, the identification is failed; when the gray type of the eye position part of the animal is uniform in gray or non-uniform in gray, acquiring the gray gain color purity of the target sub-picture subjected to gray processing in the horizontal and vertical directions, and if the gray gain color purity is higher than a preset first purity value, judging that the animal type is a dog; and if the gray gain color purity is lower than the preset second purity value and higher than the preset second purity value, judging that the animal type is the cat. The preset first purity value is larger than the preset second purity value, and specific values of the preset first purity value and the preset second purity value can be flexibly set according to actual needs.
Step S132: and acquiring the target video according to the type of the target object.
And the target video is a video corresponding to the type of the target object.
It should be understood that the different types of videos are of different interest, and therefore, the target video is acquired according to the type of the target object.
In one example, assuming that the target object is a character and the types of the target object include a boy and a girl, the target video corresponding to the boy may be a sports video (e.g., a soccer game, a basketball game, etc.), and the video corresponding to the girl may be a variety, a tv show, etc.
In another example, it is assumed that the target object is a person, the types of the target object include children, middle-aged people, and old people, the video corresponding to the children is an animation, the video corresponding to the middle-aged people is a variety, a movie, and the like, and the video corresponding to the old people is a health preserving video, and the like.
In yet another example, assuming that the target object is an animal and the type of the target object includes an animal breed, a video including an animal of the same breed may be acquired as the video, for example, assuming that the animal is a cat, the target video may be a video including a cat; assuming that the animal is a dog, the target video may be a video including a dog.
Step S133: and playing the target video.
After the target video is acquired, the target video is played to attract the attention of the target object.
The embodiment provides a video playing method, after a service object is determined to be a target object, a type of the target object is obtained according to a picture to be identified, a target video is obtained according to the type of the target object, and the target video is played.
