Referring to fig. 1, fig. 1 is a flowchart of a television control method according to an embodiment of the application.
As shown in fig. 1, the television control method includes steps S101 to S104.
Step S101, receiving current position information of a moving target sent by the radar, and determining first relative position information between the moving target and a television according to the current position information.
The television and the radar are located in the same space and are in communication connection, the radar comprises millimeter wave radar, microwave radar, laser radar and the like, the radar can be installed on the television, for example, the radar is installed at a position above the screen of the television, the radar can also be installed on other household appliances, for example, the radar is installed below the surface layer of the intelligent water dispenser, it is understood that one or more radar can be used, and the application is not limited in particular herein.
In one embodiment, the radar module is composed of a plurality of millimeter wave radars, and optionally, the working frequency of the millimeter wave radars is between 60GHz and 67GHz, and Frequency Modulation Continuous Wave (FMCW) is adopted as a transmission waveform. In some embodiments, the radar module includes an antenna array, a processing module, and a communication module. Wherein, the antenna array is used for sending and receiving electromagnetic wave signals and can be set into 3 transmitting channels and 4 receiving channels; the processing module is used for performing signal processing and data processing on electromagnetic wave signals monitored by the radar, for example, filtering noise signals in the original digital signals, and extracting a plurality of position information of a moving target moving in a radar detection range (FOV); the communication module is used for communicating with the television, such as Bluetooth communication connection, wiFi communication connection, IOT network communication connection and the like, and sending the monitored multiple pieces of position information of the moving target to the television.
In an embodiment, the radar can detect the distance information and the angle information of the target and the radar in the radar detection range in real time, and further establish a coordinate system to describe the coordinates of each target, so as to obtain the current position information of the target. Meanwhile, the radar may record the historical coordinates of the target to determine whether the target is a moving target, and transmit the current position information of the moving target to the television. The moving target may be a human, a pet, an intelligent robot, or the like capable of moving. In some embodiments, the radar or the television can draw a motion track of the target in a preset time period according to a plurality of current coordinates of the target, and store the drawn motion track in the memory, so that the motion track is convenient to call.
After the television receives the current position information of the moving target sent by the radar, determining first relative position information between the moving target and the television according to the current position information. The first relative position information comprises relative distance information and relative angle information between the moving target and the television.
Specifically, acquiring the position information of a television and the current position information of a moving target; and determining the relative distance information and the relative angle information between the mobile object and the television according to the position information of the television and the current position information of the mobile object. The position information may be coordinate information, and the relative distance information and the relative angle information may be obtained from coordinate information of both the moving object and the television. The position information of the television can be pre-stored in a memory or a database, and can also be obtained by radar monitoring, and it is understood that when the radar is installed on the television, the radar is consistent with the position information of the television.
Step S102, second relative position information between a target user watching the television and the television is obtained.
Wherein the second relative position information includes relative distance information and relative angle information between a target user and the television, the target user being a user viewing the television. In some embodiments, the second relative position information may be represented by coordinate information of both the target user and the television, for example, when coordinate information a of the television is (5, 0) and coordinate information B of the target user is (6, 5), then the second relative position information is relative distance information and relative angle information between coordinate information a (5, 0) and coordinate information B (6, 5).
In one embodiment, determining whether a user exists in a preset area in front of a screen of the television; and if the user exists in the preset area range, determining the user as a target user, and acquiring second relative position information between the target user watching the television and the television. The preset area range can be set according to actual conditions. Or if the user exists in the preset area range, determining the residence time of the user in the preset area range; and if the residence time is greater than the preset residence time, determining the user as a target user.
For example, as shown in fig. 2, in a preset area range Y in front of the television set a, the residence time to be left by the user B is 10 minutes and is greater than the preset residence time by 1 minute, and then the user B is determined to be a target user watching the television set, and second relative position information between the target user B watching the television set a and the television set a is obtained.
In one embodiment, coordinate information of a user at a plurality of time points is acquired; according to the coordinate information of the plurality of time points, determining the distance change of every two adjacent time points to obtain a plurality of distance change information; determining whether the plurality of distance change information are smaller than a preset distance change threshold value; and if the plurality of distance change information are smaller than the preset distance change threshold value, determining the user as a target user. It should be noted that, the preset distance change threshold may be set according to actual situations, and may be selected to be 2. When the distance change information is smaller than the preset distance change threshold value, the fact that the user sits on the sofa, the seat and the like is indicated, and the coordinate displacement of the user does not change greatly.
Further, if at least one distance change information is greater than or equal to a preset distance change threshold, determining a distance change trend according to the plurality of distance change information; if the distance change trend is a descending trend and the speed of the descending trend is greater than or equal to a preset speed threshold, determining the user as a target user; if the distance change trend is an ascending trend or the distance change trend is a descending trend but the speed of the descending trend is smaller than a preset speed threshold, determining that the user is not a target user. It should be noted that the preset rate threshold may be set according to practical situations, and the present application is not limited in particular. When the distance change trend is a decreasing trend, the process that the user enters the viewing area and sits is reflected, the speed of coordinate displacement is lower and lower, and finally, the trend is zero.
Step S103, determining whether the moving target causes shielding to the target user according to the first relative position information and the second relative position information.
The first relative position information includes first relative distance information and first relative angle information between the moving object and the television, and the second relative position information includes second relative distance information and second relative angle information between the object user and the television. And determining whether the moving target causes shielding to the target user according to the first relative distance information and the first relative angle information, and the second relative distance information and the second relative angle information.
In an embodiment, a first relative distance and a first relative angle in the first relative position information and a second relative distance and a second relative angle in the second relative position information are obtained; comparing the first relative distance with the second relative distance to obtain a comparison result; calculating the absolute value of the difference between the first relative angle and the second relative angle to obtain an angle difference; and determining whether the moving target causes shielding to the target user according to the comparison result and the angle difference value.
Wherein determining whether the moving target causes occlusion to the target user comprises: if the comparison result is that the first relative distance is smaller than the second relative distance and the angle difference value is in the preset angle range, determining that the moving target causes shielding to the target user; and if the comparison result shows that the first relative distance is greater than or equal to the second relative distance, or the angle difference value is not in the preset angle range, determining that the moving target does not cause shielding to the target user. It should be noted that, the preset angle range may be flexibly set and adjusted by the user, alternatively, the preset angle range is 5 degrees, that is, when the first relative distance is smaller than the second relative distance and the angle difference is within 5 degrees, it is determined that the moving object obstructs the target user.
Illustratively, as shown in fig. 3, the first relative distance information between the moving object C and the television a is AC, the first relative angle information is +.oac, the second relative distance information between the object user B and the television a is AB, and the second relative angle information is +.oab. As can be seen from the graph, the comparison result is that the first relative distance AC is smaller than the second relative distance AB, the angle difference is the absolute value of the difference between the first relative angle OAC and the second relative angle OAB, that is, the angle OAB, when the preset angle range is 5 degrees and the angle OAB is 4 degrees, the angle difference is 4 degrees within the preset angle range of 5 degrees, and it is determined that the moving target causes shielding to the target user.
Illustratively, as shown in fig. 4, the first relative distance information between the moving object C and the television a is AC, the first relative angle information is +.oac, the second relative distance information between the object user B and the television a is AB, and the second relative angle information is +.oab. As can be seen from the graph, although the comparison result is that the first relative distance AC is smaller than the second relative distance AB, the angle difference is the absolute value of the difference between the first relative angle OAC and the second relative angle OAB, i.e., the angle OAB, and the angle OAB is 8 degrees. When the preset angle range is 5 degrees and the angle difference value is 8 degrees and is not within the preset angle range of 5 degrees, determining that the moving target does not cause shielding to the target user.
Illustratively, as shown in fig. 5, the first relative distance information between the moving object C and the television a is AC, the first relative angle information is +.oac, the second relative distance information between the object user B and the television a is AB, and the second relative angle information is +.oab. It can be seen that although the angle difference is the absolute value of the difference between the first relative angle OAC and the second relative angle OAB, i.e. OAB, OAB is 3 degrees. When the preset angle range is 5 degrees, the angle difference is 3 degrees and is within the preset angle range of 5 degrees, but the comparison result is that the first relative distance AC is larger than the second relative distance AB, and it is determined that the moving target does not cause shielding to the target user.
And step S104, if the moving target causes shielding to the target user, controlling the television to pause playing.
If the moving target causes shielding to the target user, the watching effect of the target user when watching the program played by the television can be greatly influenced, and the user experience is poor. At the moment, when the moving target is detected to cause shielding to the target user, the television is controlled to pause playing, and the user experience is greatly improved.
In an embodiment, before the controlling the television to pause playing, the method further includes: acquiring shielding time of the moving target for shielding the target user; and controlling the television to pause playing when the shielding time is greater than or equal to a preset time threshold. It should be noted that the preset time threshold may be set according to the user's wish, for example, the preset time threshold is set to 3 seconds, that is, when the shielding time is greater than or equal to 3 seconds, the television is controlled to pause playing, so as to satisfy the practical application.
In an embodiment, determining a shielding area caused by the moving target according to the first relative distance and a preset shielding coefficient; and controlling the television to pause playing when the shielding area is larger than or equal to a preset area threshold value. It should be noted that, the preset shielding coefficient and the preset area threshold value can be set according to actual conditions, the shielding coefficient can be a standard value according to the height and the weight of a human, and the shielding area caused by shielding personnel under different distances can be estimated according to the standard value and the first relative distance. When the shielding area is smaller, the shielded viewing angle of the target user is limited, and the television can be stopped without pause.
In an embodiment, after the television is controlled to pause playing, continuously detecting whether the moving target causes shielding to the target user, and when detecting that the moving target does not cause shielding to the target user, controlling the television to continue playing. Or after the duration of the television pause reaches the preset time, the television is controlled to continue playing.
According to the television control method provided by the embodiment, the current position information of the moving target sent by the radar is received, the first relative position information between the moving target and the television is determined according to the current position information, the second relative position information between the target user watching the television and the television is acquired, whether the moving target is shielded for the target user is determined according to the first relative position information and the second relative position information, and if the moving target is shielded for the target user, the television is controlled to pause playing. The application can intelligently judge whether the user is shielded when watching the program, and if the user is shielded when passing by other people, the television automatically pauses playing, thereby greatly improving the experience of the user.
Referring to fig. 6, fig. 6 is a flowchart illustrating another method for controlling a television according to an embodiment of the application.
As shown in fig. 6, the television control method includes steps S201 to S207.
Step 201, receiving current coordinate information of a user sent by the radar.
The television can receive the current coordinate information of the user sent by the radar at intervals of preset time, the preset time can be flexibly set, optionally, the preset time is 0.2 seconds, namely, the current position of the user can be acquired for 5 times within 1 second, and 5 coordinate information is obtained. It should be noted that, the television may also receive the current coordinate information of the user sent by the radar in real time, and the application is not limited in particular.
In one embodiment, the radar can obtain angle information between a user and the radar according to a phase angle judgment principle; according to the signal emitted by the radar and reflected back in the direction of the user, the distance information of the user relative to the radar can be obtained through the frequency difference judgment principle; the radar or other positions can be used as the origin of coordinates to draw the current coordinate information of the user through the distance information and the angle information; and the radar sends the current coordinate information of the user to the television.
Step S202, determining the motion trail of the user in a preset time period according to the current coordinate information.
If the user walks, the coordinate information of the user at different moments is different, and the motion track of the user in a preset time period can be determined according to the multiple coordinate information of the user at different moments, wherein the preset time period can be flexibly set and can be a time period within 30 seconds after the television is started.
When the television is turned on, environmental noise caused by reflection of environmental signals exists in the detection range of the radar, but the coordinates of the environmental noise are unchanged, and the environmental noise can be shielded and filtered after standing for a certain time. For example, as shown in fig. 7, environmental noise x is generated in the detection range Z of the radar, and fig. 7 records coordinate information of the user at the time points from t1 to t6, so as to obtain a motion track of the user.
Step 203, determining whether the user is a target user watching a television according to the motion trail.
Specifically, a preset area range in front of a screen of a television is obtained; determining whether a motion trail exists in the preset area range; if yes, calculating a moving area corresponding to the motion trail; and if the moving area corresponding to the motion trail is smaller than or equal to a preset area threshold value, determining that the user is a target user watching the television. The preset area range and the area threshold can be set according to practical situations, and the moving area can be the area of a closed area surrounded by the motion track.
For example, as shown in fig. 7, there are motion trajectories t3 to t6 in a preset area range Y in front of the screen of the television, and a moving area corresponding to the motion trajectories t3 to t6 is calculated to be smaller than an area threshold value, so that the user is determined to be a target user watching the television.
Step S204, receiving the current position information of the moving target sent by the radar, and determining first relative position information between the moving target and the television according to the current position information.
The current position information comprises current coordinate information of the moving object, and the first relative position information comprises relative distance information and relative angle information between the moving object and the television.
In one embodiment, obtaining position information of a television to obtain television position information; and determining a first relative distance and a first relative angle between the moving target and the television according to the television position information and the current position information, and obtaining first relative position information. The location information may be coordinate information, and the location information of the television may be stored in the memory in advance.
Step S205, second relative position information between a target user watching the television and the television is obtained.
Wherein the second relative position information includes second relative distance information and second relative angle information between a target user and the television, the target user being a user viewing the television. In some embodiments, the second relative positional information may be represented by coordinate information of both the target user and the television.
Step S206, determining whether the moving target causes shielding to the target user according to the first relative position information and the second relative position information.
In one embodiment, calculating an absolute value of a difference between the first relative angle and the second relative angle to obtain an angle difference; determining the residence time of the angle difference value within a preset angle range; when the residence time is greater than or equal to a preset time threshold, determining that the moving target causes shielding to the target user; and when the residence time is smaller than a preset time threshold, determining that the moving target does not cause shielding to the target user.
In an embodiment, determining a shielding area caused by the moving target according to the first relative distance and a preset shielding coefficient; when the shielding area is larger than or equal to a preset area threshold value, determining that the moving target causes shielding to the target user; and when the shielding area is smaller than a preset area threshold, determining that the moving target does not cause shielding to the target user. It should be noted that, the preset shielding coefficient and the preset area threshold value can be set according to actual conditions, the shielding coefficient can be a standard value according to the height and the weight of a human, and the shielding area caused by shielding personnel under different distances can be estimated according to the standard value and the first relative distance.
Step S207, if the moving object causes shielding to the object user, the television is controlled to pause playing.
If the moving target causes shielding to the target user, the watching effect of the target user when watching the program played by the television can be greatly influenced, and the user experience is poor. At the moment, when the moving target is detected to cause shielding to the target user, the television is controlled to pause playing, and the user experience is greatly improved.
In one embodiment, a detectable range of the radar is obtained; judging whether the target user exists in the detectable range; and if the target user does not exist in the detectable range, controlling the television to pause playing or enter a standby state. The television can be paused or turned off when the user leaves, the power is saved, the user is prevented from missing the wonderful picture of the television, and the user experience is greatly improved
According to the television control method provided by the embodiment, the motion trail of the user in the preset time period is determined by receiving the current coordinate information of the user sent by the radar, whether the user is a target user watching the television or not is determined according to the motion trail, the first relative position information between the moving target and the television is determined according to the received current position information of the moving target sent by the radar, the second relative position information between the target user watching the television and the television is obtained, whether the moving target is shielded for the target user or not is determined according to the first relative position information and the second relative position information, if the moving target is shielded for the target user, the television is controlled to stop playing, whether the user is shielded when watching a program or not can be intelligently judged, and if other people are met, the television automatically stops playing when the television is temporarily shielded for pictures, and the user experience is greatly improved.
