[0045] In order to make the objectives, technical solutions and advantages of the present application clearer and more explicit, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0046] The target monitoring method described in the preferred embodiment of the present application is applied to a target monitoring system, and the target monitoring system comprises a radar module, an optical module, an acoustic module and a processing module. In this embodiment, the main body of the target monitoring system is installed in an intelligent terminal, and the intelligent terminal comprises an intelligent television and an intelligent sound, and the present embodiment is implemented by taking the intelligent television in the intelligent terminal as an example.

[0047] When the user first starts the smart TV, the smart TV prompts the user to set the position where he usually sits, and displays a simulation diagram, which includes the position of the smart TV, the recommended area, etc. Then the user selects the target area according to the simulation diagram, for example, the user usually watches TV on the sofa in front of the TV, so the front is selected as the target area in the simulation diagram.

[0048] After the user determines the target area, referring to Figure 2 , the radar module in the target monitoring system first transmits a radar signal to the target area and receives the returned radar signal. Since the radar signal attenuates with the propagation distance and differs with the number of objects in the target area, there is a difference in intensity between the returned radar signal and the transmitted radar signal. The radar module transends the intensity of the transmitted radar signal and the intensity of the returned radar signal to the processing module, and the processing module calculates the ratio of the two, for example, 30%, as the expected radar consumption rate.

[0049] In addition, referring to Figure 3 , the optical module of the target monitoring system includes a light signal transmitting unit and a light signal receiving unit, which are located on both sides of the target area. In this embodiment, the light signal receiving unit is located on the wall. After determining the target area, the light signal transmitting unit transmits a light signal to the light signal receiving unit. After the light signal receiving unit obtains the light signal, it sends the intensity value of the light signal to the optical signal transmitting unit. The optical signal transmitting unit transmits the light signal transmitted by the light signal transmitting unit and the intensity value of the light signal received by the light signal receiving unit to the processing module, and the processing module calculates the ratio between the two, for example, 50%, as the expected penetration rate.

[0050] Since the user may move the sofa, purchase a new seat, etc. in life, the expected radar consumption rate and the expected penetration rate can be recalculated at intervals, or the user can set to recalibrate the expected radar consumption rate and the expected penetration rate to improve the accuracy of subsequent target monitoring.

[0051] When the user is watching TV, the target monitoring system is started, as shown in Figure 1 , the target monitoring system performs the following steps:

[0052] Step S100, monitoring the preset target area to generate monitoring information, wherein the monitoring information includes radar information, optical information and acoustic information.

[0053] In this embodiment, the radar used by the radar module includes microwave radar, millimeter wave radar, photoelectric radar, laser radar, etc. The radar module includes a radar signal unit and a radar information sending unit. The radar information unit is installed with a radar. As shown in Figure 4 The radar module performs the following steps:

[0054] Step S111, the target area is transmitted by the transmitting wave signal.

[0055] Specifically, based on the monitoring period, the radar information unit transmits the transmitting wave signal to the target area.

[0056] Step S112, receiving the returned feedback wave signal, taking the radar transmitting intensity of the transmitting wave signal and the radar feedback intensity of the feedback wave signal as the radar information.

[0057] Specifically, the transmitting wave signal encounters an object and is reflected in various directions, i.e. feedback wave signal, part of the reflection is along the original transmitting direction, so part of the feedback wave signal will be received by the radar information unit.

[0058] The radar information unit sends the intensity of the transmitting wave signal and the intensity of the feedback wave signal, i.e. radar transmitting intensity and radar feedback intensity, to the processing module as radar information.

[0059] As shown in Figure 5 In this embodiment, the light used by the optical module can be directly the light source of the smart TV display screen, or it can be an additional invisible light source. The optical module performs the following steps:

[0060] Step S121, transmitting the light signal to the light signal receiving unit preset behind the target area.

[0061] Based on the monitoring period, the light signal transmitting unit transmits the light signal to the light signal receiving unit behind the target area. The light signal transmitted by the light signal transmitting unit is called the transmitting light signal.

[0062] Step S122, receiving the penetrating light signal, and taking the light transmitting intensity of the transmitting light signal and the light penetrating intensity of the penetrating light signal as the optical information, wherein the penetrating light signal is the signal fed back by the light signal receiving unit according to the transmitting light signal.

[0063] Specifically, the light signal receiving unit is located behind the target area. When there are other objects in the target area, the penetrating light signal received by the light signal receiving unit will inevitably be attenuated. The light signal receiving unit then sends the penetrating light signal to the optical module information sending unit.

[0064] The optical information sending unit sends the light emission intensity of the emission light signal and the light penetration intensity of the penetration light signal as the optical information to the processing module.

[0065] In this embodiment, the acoustic module includes an acoustic sensing unit and an acoustic information sending unit. Referring to Figure 6 The acoustic module performs the following steps:

[0066] Step S121, determining the number of corresponding sound sources according to the sound in the target area.

[0067] Specifically, the acoustic sensing unit includes two types, one is an acoustic sensing unit based on voiceprint extraction, which can extract voiceprints of sound in the environment. The voiceprint features of each person have commonalities, so the acoustic sensing unit can determine the number of people present in the target area according to the voiceprint features.

[0068] Further, the other is an acoustic sensing unit based on acoustic sensitive elements, referring to Figure 6 The acoustic sensing unit performs the following steps:

[0069] When there is sound in the target area, the resistance values of the plurality of acoustic sensitive elements distributed in the target area are obtained;

[0070] According to the resistance values of each acoustic sensitive element and the preset standard resistance value, the number of corresponding sound sources in the target area is determined, and the number of sound sources is taken as the acoustic information.

[0071] Specifically, the acoustic sensitive elements are distributed in the target area, which can be a belt with acoustic sensitive elements and related circuits installed in the entity, which is placed in the position of the sofa by the user in advance, and each seat of the sofa corresponds to an acoustic sensitive element. Since the acoustic sensitive element has the property of changing the resistance value according to the loudness of the sound, when there is a user speaking in the position, the resistance value of the corresponding acoustic sensitive element will change. Therefore, based on the monitoring period, the acoustic sensing unit obtains the resistance value of the acoustic sensitive element. Then the resistance value of the acoustic sensitive element and the preset standard resistance value, that is, the resistance value of the acoustic sensitive element without sound, are compared to determine how many acoustic sensitive elements have changed their resistance values, and thus determine the number of corresponding sound sources in the target area. To ensure that the change of the resistance value of the acoustic sensitive element is due to the person in the corresponding seat, the source direction of the collected sound can also be set.

[0072] Step S122, taking the number of sound sources as the acoustic information.

[0073] Specifically, after the acoustic sensing unit obtains the number of sound sources, it sends the number of sound sources as acoustic information to the processing module.

[0074] Step S200, according to the monitoring information, determine the target area corresponding to the target quantity.

[0075] Further, refer to Figure 7 , step S200 includes:

[0076] Step S210, the sound source quantity as the acoustic target quantity, respectively according to the radar emission intensity and the radar feedback intensity, and the light emission intensity and the light penetration intensity, calculate the corresponding radar target quantity and optical target quantity.

[0077] Specifically, the processing module will be the sound source quantity as the acoustic target quantity. At the same time according to the radar emission intensity and the radar feedback intensity, calculate the corresponding radar target quantity, when the target area exists target, radar emitted radar wave reflection the earlier, therefore get the radar feedback intensity is higher, according to the radar emission intensity and the radar feedback intensity, can estimate how many radar wave in the target area is reflected in advance, thereby determining the corresponding radar target quantity. Because the penetration light signal is the emission light signal through the target area, assuming that the original target area does not exist object, the penetration rate is 100%, if there is a target, due to the obstruction of the object, the penetration rate will decline, thus according to the light emission intensity and the light penetration intensity, can estimate how many mapping area of the object in the target area, so as to estimate how many quantity of target in the target area.

[0078] Further, because the radar feedback intensity is related to the distance, for example, when there is a person on the sofa, the transmission distance of the emission wave signal is closer than when there is no person, so the amount of attenuation is less, in the embodiment, the radar emission intensity is 100, and the radar feedback intensity is 40. After the processing module obtains the radar emission intensity and the radar feedback intensity, it performs the steps as shown in Figure 8 .

[0079] Step S2111, according to the radar emission intensity and the preset expected radar consumption rate, calculate the corresponding expected feedback intensity.

[0080] Specifically, first, according to the radar emission intensity and the expected radar consumption rate, calculate the corresponding expected feedback intensity, in the embodiment, the expected feedback intensity is 100x 30% = 30.

[0081] Step S2112, according to the expected feedback intensity and the radar feedback intensity, calculate the radar actual consumption rate corresponding to the radar emission intensity.

[0082] Specifically, the difference between the expected feedback intensity and the radar feedback intensity is calculated, which is equal to 40-30=10 in this embodiment. Therefore, the corresponding radar actual consumption is 10.

[0083] Then, according to the radar actual consumption and the radar emission intensity, the corresponding radar actual consumption rate is calculated, which is 10 / 100=10% in this embodiment.

[0084] In step S2113, according to the preset radar consumption list, the radar target quantity corresponding to the radar actual consumption rate is determined.

[0085] Specifically, a radar consumption list is preset, in which the target quantity corresponding to each radar actual consumption rate is listed, for example, the consumption rate of 10% is 2 people, and the consumption rate of 20% is 4 people. After calculating the radar consumption rate of this monitoring, the corresponding radar target quantity can be determined according to the radar consumption list.

[0086] Further, since the amount of light penetration is related to the amount of existing objects in the target area, the more existing objects, the less penetrating light, and the less existing objects, the more penetrating light. In this embodiment, the light emission intensity is 80, and the light penetration intensity is 30. After the processing module obtains the light emission intensity and the light penetration intensity, it performs the steps as shown in Figure 9

[0087] In step S2121, according to the light emission intensity and the preset expected light consumption rate, the corresponding expected penetration intensity is calculated.

[0088] Specifically, the expected penetration intensity is calculated according to the light emission intensity and the expected light consumption rate, which is 80x 50%=40 in this embodiment.

[0089] In step S2122, according to the expected penetration intensity and the light penetration intensity, the corresponding light additional consumption rate is calculated.

[0090] Specifically, the difference between the expected penetration intensity and the light penetration intensity is calculated, which is equal to 40-30=10 in this embodiment. Therefore, the corresponding light additional consumption is 10.

[0091] Then, according to the light additional consumption and the light emission intensity, the corresponding light additional consumption rate is calculated, which is 10 / 80=12.5%.

[0092] In step S2123, according to the light consumption list, the optical target quantity corresponding to the light additional consumption rate is determined.

[0093] ​Specifically, a light consumption list is preset, in which a target number corresponding to each light extra consumption rate is listed, for example, 2 persons for a consumption rate of 12.5% and 4 persons for a consumption rate of 25%. After the light extra consumption rate of the current monitoring is calculated, the corresponding light target number can be determined according to the light consumption list.

[0094] Step S220, when the radar target number, the optical target number and the acoustic target number are equal, the radar target number is determined as the target number corresponding to the target area.

[0095] Specifically, after the radar target number and the optical target number are obtained, the processing module compares whether the radar target number, the optical target number and the acoustic target number are equal.

[0096] In the first implementation manner of the embodiment, when the radar target number, the optical target number and the acoustic target number are all equal to 2, it is indicated that the radar target number, the optical target number and the acoustic target number are tested accurately, and then the target number corresponding to the target area is determined as 2.

[0097] In the second implementation manner of the embodiment, if not equal, there are two cases. One case is that two types of target numbers are equal, for example, the radar target number and the optical target number are equal, but the acoustic target number is not equal, and then the radar target number and the optical target number are taken as the target number corresponding to the target area. Another case is that none of the three types is equal, and then it is judged that the current monitoring fails, and the monitoring is re-performed based on the next monitoring period. Therefore, in the second implementation manner of the embodiment, it is firstly judged whether two of the radar target number, the optical target number and the acoustic target number are equal, and if yes, the equal value is taken as the target number corresponding to the target area.

[0098] Further, the target monitoring system further comprises a recommendation module connected to the processing module. According to a preset quantity recommendation table, a program recommendation menu corresponding to the target quantity is determined and displayed. The quantity recommendation table comprises different program recommendation menus corresponding to different target quantities. The program recommendation menu corresponding to different quantities can be preset, for example, two people are generally lovers, and the program recommendation menu corresponding to two people is generally a program or a movie for lovers; the program corresponding to different quantities can also be set according to the viewing habits of the user. When it is detected that the target quantity is 2, that is, the number of users currently watching the program is 2, the played programs and the dwell time of each program are recorded, and then the programs liked by the user or the programs that the user can like according to a large-scale algorithm are screened according to the historical playing records and the corresponding dwell time, and then the programs are taken as the program recommendation menu corresponding to the target quantity 2.

[0099] Further, as shown in Figure 10 Based on the above target monitoring method, the application further provides an intelligent terminal. The intelligent terminal comprises a processor 10, a memory 20 and a display 30. Figure 10 Only part of the components of the intelligent terminal are shown, but it should be understood that all the shown components are not required to be implemented, and more or fewer components can be alternatively implemented.

[0100] The memory 20 can be an internal storage unit of the intelligent terminal in some embodiments, for example, a hard disk or a memory of the intelligent terminal. The memory 20 can also be an external storage device of the intelligent terminal in other embodiments, for example, a plug-in hard disk, a smart media card (SMC), a secure digital (SD) card, a flash card and the like. Further, the memory 20 can comprise both the internal storage unit and the external storage device of the intelligent terminal. The memory 20 is used to store application software and various data installed in the intelligent terminal, for example, program codes of the installed intelligent terminal and the like. The memory 20 can also be used to temporarily store data that has been output or will be output. In an embodiment, the memory 20 stores a target monitoring program 40, which can be executed by the processor 10, so as to realize the target monitoring method in the application.
