The invention will be further explained by the description of the embodiments with reference to the drawings.
The embodiment provides a method for correcting a user gesture, as shown in fig. 1, the method includes:
s100, when the reminding function is monitored to be started, the eye image of the user is obtained.
Specifically, the reminding function is a reminding function that when a user watches a television and adopts an improper posture or posture, the smart television gives a prompt to the user. People always unconsciously adopt a posture which is self-thought to be comfortable but not healthy when watching TV: lying, side lying, lying prone, etc. When the user uses the posture for a long time during watching television, serious vision problems and physical health problems such as strabismus, humpback, spine deformation and the like can be caused to the developing children and teenagers, and problems such as unsmooth breathing, insufficient spine blood supply and the like can be caused to adults, thus the physical health of the user is damaged. The existing technology only identifies the body state, but because many users are used to turn on the television and have voice but do not watch the television at present, the body state identification not only has no effect but also influences the requirement that the users only want to listen to the television for playing, so that the function of only identifying the body state in the watching state and prompting the user is necessary.
In the invention, under the condition that the reminding function is started, the television system works in real time after being started, the correction system identifies the watching state and the watching posture of the user in real time, the user is prompted under the condition that the user watches and adopts the wrong posture, and the condition that the user does not watch the television although the user adopts the relaxation postures of lying on the stomach and lying down and the like is filtered. Therefore, the requirement that only the improper posture of the user for watching the television can send out the correction prompt is met. In this embodiment, whether the user in front of the television is actually watching the television is confirmed by acquiring the eye image of the user.
Further, as shown in fig. 2, fig. 2 is a flowchart of step S100 in the method for correcting the user gesture provided by the present invention. When it is monitored that the reminding function is started, acquiring the eye image of the user specifically comprises:
s101, collecting a user face image in a visual angle range through a camera;
s102, extracting the eye image of the user according to the face image of the user.
Specifically, the smart television of the present invention may be configured with a camera in advance, and image information of the user may be acquired through the camera, where the image information may be a face image of the user, a depth image of the user, and the like. In this embodiment, a camera is used to collect a face image of a user within a shooting range of the camera, and then an eye image of the user is extracted according to the face image of the user. Therefore, whether the user is watching the television or not is accurately judged according to the eye images of the user.
S200, determining whether the user watches the television or not according to the eye image.
In this embodiment, as shown in fig. 3, fig. 3 is a flowchart of step S200 in the method for correcting the user gesture provided by the present invention. The determining whether the user watches the television according to the eye image specifically includes:
s201, determining whether the camera shoots the eyes of the user according to the eye image of the user;
s202, if the camera shoots the eyes of the user, acquiring the eye images of the user again after a first preset time, and if the eye images acquired again shoot the eyes of the user, judging that the user watches the television;
and S203, if the camera does not shoot the eyes of the user, judging that the user does not watch the television.
Specifically, when a user normally watches a television, the eyes of the user are over against the television, so that it can be considered that when the user watches the television, the camera of the smart television can shoot the eyes of the user, therefore, the invention determines whether the camera shoots the eyes of the user according to the eye images of the user, if the camera shoots the eyes of the user, the eye images of the user are obtained again after a first preset time period, and if the eye images obtained again shoot the eyes of the user, the user is determined to be watching the television, because even if the user watches the television, there may be scenes that the user is in other things, for example, the user looks up at the television when playing a mobile phone, and the like, at this time, if the user is determined to be watching the television, the user is inaccurate, so the eye images of the user need to be obtained again after the first preset time period, if the eyes of the user are shot by the eye images obtained again, the user is judged to be in a television watching state, and therefore accuracy of judging whether the user watches the television is improved. In this embodiment, the first preset time period is preferably 3 minutes. It can be understood that when the camera does not shoot the eyes of the user, it is determined that the user is not watching the television.
Further, in an implementation manner of this embodiment, the method for correcting the user gesture further includes: turning off the television upon determining that the user is not watching the television.
Specifically, the step aims to turn off the television when the human eye image of the user is not acquired in the preset period, and the step can be used for automatically turning off the television when the user does not watch the television, so that the power is saved.
S300, when the user is confirmed to watch the television, acquiring the posture information of the user, and comparing the posture information with preset posture information.
Specifically, the invention acquires the posture information of the user after determining that the user watches the television, and compares the posture information with the preset posture information. In this embodiment, the posture information includes skeletal posture information of the user, and the preset posture information refers to a data threshold of a posture of the user for improperly watching the television. Therefore, after the user is determined to watch the television, the smart television can acquire the bone posture information of the user in real time and compare the acquired bone posture information of the user with the preset posture information, so that whether the user is in an improper posture/posture to watch the television can be determined. It should be noted that how to confirm the preset posture information and the comparison process of the posture information of the user are prior art, and the present invention is not described in detail again.
S400, if the posture information is within the preset posture information range, reminding a user to correct the posture.
Specifically, if the posture information is within the preset posture information range, it is indicated that the user is in an improper posture/posture to watch the television, and a prompt of the current watching posture being improper is given to the user.
Further, in an implementation manner of this embodiment, if the posture information is within the preset posture information range, reminding the user to correct the posture specifically includes:
s401, if the attitude information is in the preset attitude information range, judging the holding time of the attitude information;
s402, if the duration exceeds the preset duration, reminding a user to correct the posture.
In this embodiment, the preset duration is 30s, correspondingly, if the posture information is within the preset posture information range, it is determined that the user is in an inappropriate posture at the current time and watching the television, next, the duration for holding the inappropriate posture of the user can be calculated, and if the duration for holding the posture of the user in the watching state exceeds 30s, the user can be determined to be corrected, so that the smart television can remind the user of correcting the posture.
In this embodiment, the reminding the user to correct the posture specifically includes: and popping up a prompt on a television screen to remind a user of correcting the posture. For example, the prompt may be prompt information such as "the current viewing posture is improper". Thus, the user can be aware that the user should not take the posture for watching but sit and watch, and the inconvenience caused by taking the preset posture for rest, which is not watched by the user, is avoided.
Further, in an implementation manner of this embodiment, the method for correcting the user gesture further includes:
s4021, popping up a prompt on a television screen to remind a user of correcting the posture, then obtaining posture information of the user again, and comparing the posture information with preset posture information;
s4022, if the posture information acquired again is not in the preset posture information range, closing the prompt.
Specifically, after a prompt is popped up on the screen of the smart television, ten users can be reserved for 30 seconds to adjust the posture information of watching the television, after 30 seconds, the posture information of the user at the moment is obtained again according to the method, the obtained posture information is compared with the preset posture information, and if the obtained posture information is not in the preset posture information range, the prompt is closed. Therefore, the user can always watch the television in a correct posture, an effective correcting/correcting effect is achieved, and the body health of the user is facilitated.
In an implementation manner of this embodiment, as shown in fig. 4, fig. 4 is a flowchart of another embodiment of a method for correcting a user gesture provided by the present invention, where the method includes the following steps:
s1, starting the camera when the reminding switch is turned on, and acquiring the eye image of the user at the moment;
s2, processing the eye images acquired by the camera, and identifying the positions of the two eyes of the viewer;
s3, judging whether the viewer watches the television according to whether the eyes are identified, if so, executing the step S4, otherwise, skipping to execute the step S10;
s4, acquiring the bone posture of the user at the moment through the camera;
s5, extracting key bone points of the obtained bone conditions;
s6, comparing the bone with the preset bone range of the storage module, executing the step S7 if the offset angle of the bone is within the threshold value, otherwise, jumping to the step S11;
s7, starting timing when the skeleton information is identified to be within a preset range;
s8, judging whether the watching posture keeps 30S or not, if so, jumping to the step S9, otherwise, jumping to the step S1;
s9, popping up a prompt word which is watched in an improper posture on the television screen, and the prompt word does not disappear until the user sits well;
s10, clearing the timing at the moment, and then executing the step S1;
s11, the timer is cleared, and then step S4 is executed.
In this embodiment, it can be seen from the above steps that after the television is turned on and the reminder switch is turned on, the correction device can automatically obtain the eye information and the bone information of the user who is watching through the camera. When the correction system judges that the whole eyes of the user are in the image through the recognition of the eyes of the user, the user is considered to be watching television, and the skeletal information is compared at the moment. When the value of the key point of discernment in the skeleton information when predetermined lie and bow to lie prone wrong posture threshold value within range, then begin to time this posture hold time, if this posture hold time surpasss 30S under watching the state, then can think this user need be corrected, pop out and watch the improper warning of posture this moment to can correct the user and watch the posture, guaranteed again that the user is not having a rest or not watching relaxation postures such as lying prone of adopting under the television state.
