[0076] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0077] The present disclosure provides an information transmission method, which is applied to a terminal. The method transmits information through visible light, which is very safe for users. Moreover, visible light transmitting devices are relatively common, and the requirements for the location of the visible light transmitting devices are relatively low. Moreover, visible light is convenient for carrying more information, increasing the transmission speed of information, thereby increasing the response speed of the corresponding terminal. In addition, the method is not subject to radio spectrum control, does not require a radio spectrum license, and has no electromagnetic interference. It can be applied to hospitals, airplanes, space stations and other places where electromagnetic interference is strictly restricted.

[0078] In an exemplary embodiment, a method for transmitting information is provided, which is applied to a terminal. Figure 1As shown, the method includes:

[0079] S110, determining first spectrum information of first visible light;

[0080] S120, determining target light parameter information according to the first spectrum information;

[0081] S130, determining a second visible light for carrying information to be transmitted according to the target light parameter information;

[0082] S140: Emit second visible light to transmit the information to be transmitted.

[0083] In step S110, the first visible light is the visible light in the environment where the first terminal is located, which may include the visible light emitted by the first terminal, and may also include the visible light emitted by other visible light emitting devices.

[0084] The first visible light may be collected by a visible light collection device of the first terminal, or may be obtained by other means, which are not limited here. For example, the first visible light may be collected by other terminals and then transmitted to the first terminal.

[0085] Among them, after the first visible light is collected by the visible light collection device of the first terminal, the collection device can transmit the collected information to the processor of the first terminal, so that the processor obtains the first visible light, and then processes the first visible light to determine the first spectrum information.

[0086] The acquisition device may include at least one of the following: a light sensor, a color sensor, a spectrum sensor, etc. The terminal may be provided with more than one acquisition device to ensure the reliability of the first visible light collected. When the terminal is provided with more than one acquisition device, each acquisition device may collect visible light at different angles, and the first visible light includes the visible light at the above different angles. Then, the final first spectrum information is determined by the spectrum information of the visible light at different angles to better reflect the spectrum information of the ambient light.

[0087] The spectrum information can be obtained by Fourier transforming the collected visible light, and the spectrum information includes information such as the frequency and the light intensity of the light of the corresponding frequency.

[0088] Example 1,

[0089] The terminal is a mobile phone, and the mobile phone can be provided with three acquisition devices, namely a front acquisition device provided on the front of the mobile phone, a rear acquisition device provided on the back of the mobile phone, and a top acquisition device provided on the top of the mobile phone.

[0090] The visible light collected by the front collection device can be referred to as the front visible light, the visible light collected by the rear collection device can be referred to as the rear visible light, and the visible light collected by the top collection device can be referred to as the top visible light.

[0091] The front visible light is subjected to Fourier transform to obtain the front spectrum information, the rear visible light is subjected to Fourier transform to obtain the rear spectrum information, and the top visible light is subjected to Fourier transform to obtain the top spectrum information.

[0092] Then, the final first spectrum information is determined according to the front spectrum information, the rear spectrum information and the top spectrum information. The first spectrum information includes the frequency of the first visible light and the light intensity corresponding to each frequency.

[0093] The union or intersection of the front spectrum information, the rear spectrum information and the top spectrum information may be determined as the first spectrum information. Alternatively, the first spectrum information may be determined according to the front spectrum information, the rear spectrum information and the top spectrum information in other ways, which will not be described in detail here.

[0094] In step S120, the target light parameter information may include light parameters such as light frequency values ​​and light intensity values. For example, the maximum light frequency value and the maximum light intensity value in the first spectrum information may be determined. Then, the light frequency value greater than the maximum light frequency value is determined as the target light frequency value, and the light intensity value greater than the maximum light intensity value is determined as the target light intensity value. Finally, the target light frequency value and the target light intensity value are determined as the target light parameter information.

[0095] Example 2,

[0096] The first spectrum information may include light frequency value P1, light frequency value P2, light frequency value P3, light frequency value P4 and light frequency value P5, as well as light intensity value D1 corresponding to light frequency value P1, light intensity value D2 corresponding to light frequency value P2, light intensity value D3 corresponding to light frequency value P3, light intensity value D4 corresponding to light frequency value P4 and light intensity value D5 corresponding to light frequency value P5.

[0097] Among them, the light frequency value P1 is the maximum light frequency value, and the light intensity value D3 is the maximum light intensity value. In this example, the light parameter information whose light frequency value is greater than the light frequency value P1 and whose light intensity value is greater than the light intensity value D3 can be determined as the target light parameter information.

[0098] In step S130, after the target light parameter information is determined, the visible light corresponding to the target light parameter information can be determined as the target visible light for carrying the information to be transmitted. Then, according to the information conversion rule between the information to be transmitted and the visible light, the information to be transmitted is loaded into the target visible light to form the second visible light.

[0099] The light frequency value of the second visible light is the light frequency value in the target light parameter information, and the light intensity value of the second visible light is the light intensity value in the target light parameter information.

[0100] Example 3,

[0101] The target light parameter information includes the light intensity value D and the light frequency value P. The information conversion rules include sub-conversion rules between the information to be transmitted and the binary information, and sub-conversion rules between the binary information and visible light. Among them, the presence of visible light and lasting for 0.1 seconds represents "0" in binary; the absence of visible light and lasting for 0.1 seconds represents "1" in binary.

[0102] Assuming that the information to be transmitted is converted into binary information as "011000110", in this case, the first terminal can be controlled to emit visible light with a light intensity value of D and a light frequency value of P, and the visible light flashes and emits in the following pattern: 0 seconds to 0.1 seconds to emit, 0.1 seconds to 0.3 seconds to not emit, 0.3 seconds to 0.6 seconds to emit, 0.6 seconds to 0.8 seconds to not emit, 0.8 seconds to 0.9 seconds to emit. The flashing visible light is the second visible light.

[0103] It should be noted that in this method, the target light parameter information may include one light parameter group or more than one light parameter group, which is not limited here. Each light parameter group may include a light intensity value and a light frequency value.

[0104] In step S140, the second visible light may be emitted by a light emitting device of the first terminal, which may be a light emitting device such as a flashlight, a flashlight or a display screen of the first terminal. Of course, a light emitting device specifically used for transmitting information may also be provided in the first terminal, which will not be described in detail here.

[0105] This method uses visible light to transmit information. Visible light transmitting equipment is also relatively common. Visible light is very safe for humans and has low requirements for the location of the visible light transmitting equipment. It can not only reduce terminal costs, but also facilitate the carrying of more information and increase the transmission speed of information, thereby increasing the response speed of the corresponding terminal. In addition, information transmission through visible light is not subject to radio spectrum regulation and does not require a radio spectrum license. Moreover, visible light has no electromagnetic interference, so this method can also be used in hospitals, airplanes, space stations and other places where electromagnetic interference is strictly restricted.

[0106] In an exemplary embodiment, an information transmission method is provided, which is applied to a first terminal. In the method, the first spectrum information includes sub-spectrum information corresponding to at least one light collection frequency band. When the first visible light is determined by a light collection device, the light collection frequency band is related to the collection device.

[0107] When the acquisition device is a light sensor, the first spectrum information only includes sub-spectrum information corresponding to one light acquisition frequency band, that is, the sub-spectrum information is the same as the first spectrum information. The light acquisition frequency band is the frequency band of all visible light.

[0108] When the acquisition device is a color sensor, the first spectrum information includes sub-spectrum information corresponding to three light acquisition frequency bands, wherein the three light acquisition frequency bands correspond to the visible light of the three light frequency bands that the color sensor can collect. It includes the R band corresponding to the red channel (R channel), the G band corresponding to the green channel (G channel), and the B band corresponding to the blue channel (B channel). It should be noted that the color sensor only divides the collected visible light into three light frequency bands, and does not limit the specific color of the visible light. For example, the R band does not only refer to the light frequency band of red visible light, it can also include other visible light frequency bands adjacent to the frequency band where the red visible light is located.

[0109] When the acquisition device is a spectral sensor, the first spectrum information includes sub-spectrum information corresponding to seven light acquisition frequency bands, wherein the seven light acquisition frequency bands correspond to the visible light of the seven light frequency bands that can be collected by the spectral sensor, which will not be elaborated here.

[0110] In the method, determining the target light parameter information according to the first spectrum information may include:

[0111] S210, determining target spectrum information corresponding to each sub-spectrum information according to a set frequency condition and each sub-spectrum information;

[0112] S220, determining a first light parameter group corresponding to each target spectrum information;

[0113] S230. Determine target light parameter information according to all first light parameter groups.

[0114] In step S210, the set frequency condition may be set before the terminal leaves the factory, or may be set after the terminal leaves the factory, and the set frequency condition may be modified later to better meet different needs of users.

[0115] The setting frequency condition may include at least one setting light frequency band, and each setting light frequency band corresponds to a sub-spectrum information. In the mutually corresponding light collection frequency band and the setting light frequency band, the light collection frequency band generally includes the setting light frequency band. It can be understood that the setting light frequency band may be related to the light frequency band of visible light that can be emitted by the first terminal. For example, the setting light frequency band is the same as the light frequency band of visible light that can be emitted by the first terminal.

[0116] In this step, the spectrum information corresponding to the corresponding set light frequency band in each sub-spectrum information may be determined as the target spectrum information corresponding to the sub-spectrum information.

[0117] Example 1,

[0118] There are three sub-spectrum information, which are recorded as the first sub-spectrum information, the second sub-spectrum information and the third sub-spectrum information. Among them, the first sub-spectrum information corresponds to the set light frequency band △S1, the second sub-spectrum information corresponds to the set light frequency band △S2, and the third sub-spectrum information corresponds to the set light frequency band △S3. It can be seen that the target spectrum information corresponding to the first sub-spectrum information is the spectrum information corresponding to the set light frequency band △S1 in the first sub-spectrum information; the target spectrum information corresponding to the second sub-spectrum information is the spectrum information corresponding to the set light frequency band △S2 in the second sub-spectrum information; the target spectrum information corresponding to the third sub-spectrum information is the spectrum information corresponding to the set light frequency band △S3 in the third sub-spectrum information.

[0119] In step S220, the first light parameter group includes a maximum light intensity value in the corresponding target spectrum information, and a maximum light frequency value corresponding to the maximum light intensity value.

[0120] After determining the target spectrum information, the maximum light intensity value in each target spectrum information and the maximum light frequency value corresponding to the maximum light intensity value can be determined, and then the above maximum light intensity value and maximum light frequency value are determined as the first light parameter group corresponding to the target spectrum information.

[0121] For example, three target spectrum information are determined in this step, which are recorded as the first target spectrum information, the second target spectrum information and the third target spectrum information, wherein the maximum light intensity value of the first target spectrum information is D1 and the maximum light frequency value is P1, the maximum light intensity value of the second target spectrum information is D2 and the maximum light frequency value is P2, and the maximum light intensity value of the third target spectrum information is D3 and the maximum light frequency value is P3. It can be seen that the first light parameter group corresponding to the first target spectrum information is the light intensity value D1 and the light frequency value P1, the first light parameter group corresponding to the second target spectrum information is the light intensity value D2 and the light frequency value P2, and the first light parameter group corresponding to the third target spectrum information is the light intensity value D3 and the light frequency value P3.

[0122] In step S230, after all the first light parameter groups are determined, the light intensity value of each first light parameter group can be determined, and the maximum light intensity value can be determined therefrom and recorded as the reference light intensity value. Then the light frequency value corresponding to the reference light intensity value is determined and recorded as the reference light frequency value. Finally, the target light parameter information is determined based on the above reference light intensity value and the reference light frequency value. For example, the light intensity value greater than the above reference light intensity value can be determined as the light intensity value of the target light parameter information; and the light frequency value greater than the above reference light frequency value can be determined as the light frequency value of the target light parameter information. In this way, the target light parameter information can be determined based on the reference light intensity value and the reference light frequency value.

[0123] In this method, the amount of data processing can be reduced, the speed of determining target light parameter information can be further increased, and the user experience is improved.

[0124] In an exemplary embodiment, an information transmission method is provided, which is applied to a first terminal. In the method, according to a set frequency condition and each sub-spectrum information, determining the target spectrum information corresponding to each sub-spectrum information may include:

[0125] S310, determining the maximum light frequency value in the sub-spectrum information;

[0126] S320, multiplying the set ratio by the maximum light frequency value to determine the cutoff light frequency value;

[0127] S330, determining a light frequency band between the cutoff light frequency value and the maximum light frequency value as a target light frequency band;

[0128] S340: Determine the spectrum information corresponding to the target light frequency band in the sub-spectrum information as the target spectrum information of the sub-spectrum information.

[0129] In step S310, each sub-spectrum information includes a light frequency band and a light intensity value corresponding to each light frequency value in the light frequency band. In this step, the maximum light frequency value in the light frequency band of each sub-spectrum information needs to be determined.

[0130] In step S320, setting the frequency condition includes setting a ratio, which may be set before the first terminal leaves the factory or after the first terminal leaves the factory, and the set ratio may be modified later to better meet the needs of the user. The set ratio may be 90%, 85%, 75%, etc.

[0131] In this step, the product of the maximum light frequency value corresponding to each sub-spectrum information and the set ratio is determined as the cutoff light frequency value corresponding to the corresponding sub-spectrum information.

[0132] Example 1,

[0133] The ratio is set to 75%. There are three sub-spectrum information, which are recorded as the first sub-spectrum information, the second sub-spectrum information and the third sub-spectrum information. Among them, the maximum light frequency value corresponding to the first sub-spectrum information is recorded as P1, the maximum light frequency value corresponding to the second sub-spectrum information is recorded as P2, and the maximum light frequency value corresponding to the third sub-spectrum information is recorded as P3. It can be seen that the cutoff light frequency value corresponding to the first sub-spectrum information is 75% P1, the cutoff light frequency value corresponding to the second sub-spectrum information is 75% P2, and the cutoff light frequency value corresponding to the third sub-spectrum information is 75% P3.

[0134] In step S330, a light frequency band between a cutoff light frequency value corresponding to the sub-spectrum information and a maximum light frequency value corresponding to the sub-spectrum information may be determined as a target light frequency band corresponding to the sub-spectrum information.

[0135] Example 2,

[0136] There are three sub-spectrum information, which are recorded as the first sub-spectrum information, the second sub-spectrum information and the third sub-spectrum information. Among them, the maximum light frequency value corresponding to the first sub-spectrum information is recorded as P1, the maximum light frequency value corresponding to the second sub-spectrum information is recorded as P2, and the maximum light frequency value corresponding to the third sub-spectrum information is recorded as P3. The cutoff light frequency value corresponding to the first sub-spectrum information is 75% P1, the cutoff light frequency value corresponding to the second sub-spectrum information is 75% P2, and the cutoff light frequency value corresponding to the third sub-spectrum information is 75% P3. It can be seen that the target light frequency band △P1 corresponding to the first sub-spectrum information is the light frequency band between the light frequency value 75% P1 and the light frequency value P1; the target light frequency band △P2 corresponding to the second sub-spectrum information is the light frequency band between the light frequency value 75% P2 and the light frequency value P2; the target light frequency band △P3 corresponding to the third sub-spectrum information is the light frequency band between the light frequency value 75% P3 and the light frequency value P3.

[0137] In step S340, after the target light frequency band corresponding to the sub-spectrum information is determined, the spectrum information corresponding to the target light frequency band in the sub-spectrum information may be determined as the target spectrum information corresponding to the sub-spectrum information.

[0138] Example 3,

[0139] There are three sub-spectrum information, which are recorded as the first sub-spectrum information, the second sub-spectrum information and the third sub-spectrum information. Among them, the first sub-spectrum information corresponds to the target light frequency band △P1, the second sub-spectrum information corresponds to the target light frequency band △P2, and the third sub-spectrum information corresponds to the target light frequency band △P3. It can be seen that the target spectrum information corresponding to the first sub-spectrum information is the spectrum information corresponding to the target light frequency band △P1 in the first sub-spectrum information; the target spectrum information corresponding to the second sub-spectrum information is the spectrum information corresponding to the target light frequency band △P2 in the second sub-spectrum information; the target spectrum information corresponding to the third sub-spectrum information is the spectrum information corresponding to the target light frequency band △P3 in the third sub-spectrum information.

[0140] In this method, by filtering the target spectrum information from each sub-spectrum signal information based on a set ratio, the subsequent data processing volume can be reduced, which can improve the efficiency of the entire method to a certain extent and enhance the user experience.

[0141] In an exemplary embodiment, an information transmission method is provided, which is applied to a first terminal. In the method, determining target light parameter information according to all first light parameter groups may include:

[0142] S410, determining at least one reference light parameter group according to all first light parameter groups;

[0143] S420, determining a target light parameter group corresponding to each reference light parameter group;

[0144] S430: Determine all target light parameter groups as target light parameter information.

[0145] In step S410, when the acquisition device of the first terminal is a light sensor, the number of the first light parameter group is one, and the first light parameter group can be directly determined as the reference light parameter group.

[0146] When the acquisition device is a color sensor, the number of first light parameter groups is three, corresponding to the R band, the G band, and the B band, respectively. In this case, the light intensity value of each first light parameter group can be determined first, and then a set number (e.g., 1 or 2) of the smaller light intensity values ​​among the three light intensity values ​​can be determined as reference light intensity values. Finally, the first light parameter group corresponding to each reference light intensity value is determined as the reference light parameter group.

[0147] Example 1,

[0148] The number is set to 1. There are three first light parameter groups, corresponding to the R band, the G band, and the B band. Among them, the light intensity value of the first light parameter group corresponding to the R band is the largest, and the light intensity value of the first light parameter group corresponding to the G band is the smallest. In this example, the light intensity value of the first light parameter group corresponding to the G band can be determined as the reference light intensity value, and then the first light parameter group corresponding to the G band can be determined as the reference light parameter group.

[0149] When the acquisition device is a spectral sensor, the number of the first light parameter groups is seven, corresponding to seven light frequency bands. In this case, the light intensity value of each first light parameter group can be determined first, and then a smaller set number (such as 2, 3 or 4, etc.) of the seven light intensity values ​​can be determined as reference light intensity values. Finally, the first light parameter group corresponding to each reference light intensity value is determined as the reference light parameter group.

[0150] Example 2,

[0151] The number is set to 2. The number of the first light parameter groups is seven, corresponding to seven light frequency bands respectively. The seven light frequency bands can be referred to as red frequency band, orange frequency band, yellow frequency band, green frequency band, cyan frequency band, blue frequency band and purple frequency band respectively.

[0152] The light intensity value of the first light parameter group corresponding to the red frequency band is recorded as D1, the light intensity value of the first light parameter group corresponding to the orange frequency band is recorded as D2, the light intensity value of the first light parameter group corresponding to the yellow frequency band is recorded as D3, the light intensity value of the first light parameter group corresponding to the green frequency band is recorded as D4, the light intensity value of the first light parameter group corresponding to the cyan frequency band is recorded as D5, the light intensity value of the first light parameter group corresponding to the blue frequency band is recorded as D6, and the light intensity value of the first light parameter group corresponding to the purple frequency band is recorded as D7. Among them, the above seven light intensity values ​​are D2, D5, D1, D3, D4, D7 and D6 from small to large.

[0153] In this example, the light intensity value recorded as D2 and the light intensity value recorded as D5 can be determined as reference light intensity values, and the first light parameter group corresponding to the orange frequency band and the first light parameter group corresponding to the cyan frequency band can be determined as reference light parameter groups.

[0154] It should be noted that the reference light parameter group may also be determined by other methods, which will not be described in detail here.

[0155] In step S420, in the corresponding reference light parameter group and target light parameter group, the light intensity value of the target light parameter group is greater than the light intensity value of the reference light parameter group, and the light frequency value of the target light parameter group is greater than the light frequency value of the reference light parameter group.

[0156] The difference between the light intensity value of the target light parameter group and the light intensity value of the reference light parameter group may be a set light intensity difference. The set light intensity difference may be set before the first terminal leaves the factory, or may be set after the first terminal leaves the factory, and the set light intensity difference may be modified later to better meet user needs.

[0157] The difference between the light frequency value of the target light parameter group and the light frequency value of the reference light parameter group may be a set light frequency difference. The setting method of setting the light frequency difference is similar to the setting method of setting the light intensity difference. It may be set before the first terminal leaves the factory or after the first terminal leaves the factory. In addition, the set light frequency difference may be modified later to better meet user needs.

[0158] Example 3,

[0159] There are two reference light parameter groups, which are respectively recorded as a first reference light parameter group and a second reference light parameter group. The first reference light parameter group may include a light frequency value P1 and a light intensity value D1, and the second reference light parameter group may include a light frequency value P2 and a light intensity value D2.

[0160] The light intensity difference is set to D0, and the light frequency difference is set to P0. It can be seen that the target light parameter group corresponding to the first reference light parameter group includes the light frequency value P1+P0 and the light intensity value D1+D0; the target light parameter group corresponding to the second reference light parameter group includes the light frequency value P2+P0 and the light intensity value D2+D0.

[0161] In step S430, after the target light parameter group corresponding to each reference light parameter group is determined, all target light parameter groups may be determined as target light parameter information. That is, the target light parameter information includes all target light parameter groups.

[0162] This method can determine more appropriate target light parameter information, so that more appropriate visible light can be used to carry the information to be transmitted, so as to better ensure the reliability of information transmission and improve the user experience.

[0163] In an exemplary embodiment, an information transmission method is provided, which is applied to a first terminal. In the method, determining at least one reference light parameter group according to the light intensity values ​​of all first light parameter groups may include at least one of the following methods:

[0164] Method 1: if the reference light intensity value is less than or equal to the set intensity value, each first light parameter group is determined as a reference light parameter group;

[0165] Mode 2: If the reference light intensity value is greater than the set intensity value, and there is no light intensity value whose difference with the reference light intensity value is greater than or equal to the set threshold value among all the first light parameter groups, then the first light parameter group with the smallest light intensity value among all the first light parameter groups is determined as the reference light parameter group;

[0166] Method 3: If the reference light intensity value is greater than the set intensity value, and among all the first light parameter groups, there is a light intensity value whose difference with the reference light intensity value is greater than or equal to the set threshold, then the first light parameter group corresponding to the light intensity value is determined as the reference light parameter group.

[0167] The reference light intensity value is the maximum light intensity value among all the light intensity values ​​of the first light parameter group.

[0168] In this method, the set strength value can be set before the terminal leaves the factory, or it can be set after the terminal leaves the factory, and the set strength value can be modified later to better meet user needs. The setting threshold is similar to the setting method of the set strength value, which can be set before the terminal leaves the factory, or it can be set after the terminal leaves the factory, and the setting threshold can be modified later to better meet user needs.

[0169] The specific values ​​of the intensity value and the threshold value can be set according to the actual situation and are not limited here. Generally, the intensity value is between 30Lx and 500Lx, and the threshold value is generally greater than or equal to 10Lx.

[0170] Example 1,

[0171] The intensity value is set to 200 Lx, and the threshold is set to 10 Lx. The number of the first light parameter group is three, and the light intensity values ​​thereof are light intensity value D1, light intensity value D2, and light intensity value D3, wherein light intensity value D1 is the largest and light intensity value D3 is the smallest.

[0172] If the light intensity value D1 is less than or equal to 200 Lx, each first light parameter set may be determined as a reference light parameter set.

[0173] If the light intensity value D1 is greater than 200 Lx, and the difference between the light intensity value D1 and the light intensity value D2 is less than 10 Lx, and the difference between the light intensity value D1 and the light intensity value D3 is also less than 10 Lx, the first light parameter group corresponding to the light intensity value D3 can be determined as the reference light parameter group.

[0174] If the light intensity value D1 is greater than 200 Lx, and the difference between the light intensity value D1 and the light intensity value D2 is less than 10 Lx, and the difference between the light intensity value D1 and the light intensity value D3 is greater than or equal to 10 Lx, the first light parameter group corresponding to the light intensity value D3 can be determined as the reference light parameter group.

[0175] If the light intensity value D1 is greater than 200Lx, and the difference between the light intensity value D1 and the light intensity value D2 is greater than or equal to 10Lx, and the difference between the light intensity value D1 and the light intensity value D3 is also greater than or equal to 10Lx, then the first light parameter group corresponding to the light intensity value D2 can be determined as the reference light parameter group, and the first light parameter group corresponding to the light intensity value D3 can be determined as the reference light parameter group.

[0176] In this method, a more appropriate reference light parameter group can be determined, thereby reducing the requirement on the light intensity value of the second visible light and saving power.

[0177] In an exemplary embodiment, an information transmission method is provided, which is applied to a first terminal. In the method, determining a second visible light for carrying information to be transmitted according to target light parameter information and emitting the second visible light may include:

[0178] S510, sending a first information conversion rule to a second terminal;

[0179] S520, receiving a target information conversion rule fed back by the second terminal;

[0180] S530. According to the target information conversion rule, load the information to be transmitted into the visible light corresponding to the target light parameter information to determine the second visible light.

[0181] In step S510, the first information conversion rule is an information conversion rule supported by the first terminal. The information conversion rule refers to a conversion rule between optical information and information to be transmitted. The information to be transmitted may include various information such as numbers, text, and symbols.

[0182] The information conversion rules can be set according to user needs and are not limited here. For example, the information conversion rules may include at least one of the following:

[0183] Rule 1: light corresponds to the information to be transmitted "1", and no light corresponds to the information to be transmitted "0";

[0184] Rule 2: If there is light and the light lasts for the first time, it corresponds to the information to be transmitted "1"; if there is no light and the light lasts for the second time, it corresponds to the information to be transmitted "0". The first time and the second time can be the same or different. The setting method of the first time and the second time is similar to the setting method of setting the intensity value in other examples, so it will not be repeated here;

[0185] Rule 3: The visible light in the R band corresponds to the information to be transmitted "0", the visible light in the G band corresponds to the information to be transmitted "1", and the visible light in the B band corresponds to the information to be transmitted "2";

[0186] Rule 4: visible light in the red frequency band corresponds to information to be transmitted "0", visible light in the orange frequency band corresponds to information to be transmitted "1", visible light in the yellow frequency band corresponds to information to be transmitted "2", visible light in the green frequency band corresponds to information to be transmitted "3", visible light in the cyan frequency band corresponds to information to be transmitted "4", visible light in the blue frequency band corresponds to information to be transmitted "5", and visible light in the purple frequency band corresponds to information to be transmitted "6";

[0187] Rule 5: Visible light in the nth frequency band and the nth light intensity range corresponds to the information to be transmitted Cn, where n is a positive integer greater than or equal to 1.

[0188] The first information conversion rule may include at least one of the above information conversion rules.

[0189] In step S520, the target information conversion rule is determined by the second terminal according to the second information conversion rule and the received first information conversion rule, and the second information conversion rule is an information conversion rule supported by the second terminal. The second information conversion rule may also be at least one of the above information conversion rules.

[0190] After receiving the first information conversion rule, the second terminal may find an information conversion rule identical to the first information conversion rule from the second information conversion rules, and then determine at least one of the identical information conversion rules as a target information conversion rule.

[0191] Example 1,

[0192] The first information conversion rule includes rule 1 and rule 5, and the second information conversion rule includes rule 2 and rule 5. In this example, rule 5 can be determined as the target information conversion rule.

[0193] Example 2,

[0194] The first information conversion rule includes rule 1, rule 2 and rule 5, and the second information conversion rule includes rule 2, rule 3 and rule 5. In this example, rule 2 or rule 5 can be determined as the target information conversion rule.

[0195] Example 3,

[0196] The first information conversion rule includes rule 1, rule 2 and rule 5, and the second information conversion rule includes rule 2, rule 3 and rule 5. In this example, both rule 2 and rule 5 can be determined as target information conversion rules.

[0197] In step S530, after the target information conversion rule is determined, the information to be transmitted can be loaded into the visible light corresponding to the target light parameter information based on the target information conversion rule to form a second visible light carrying the information to be transmitted, and the second visible light is emitted from the first terminal to the second terminal to realize information transmission between the first terminal and the second terminal.

[0198] It should be noted that the sending of the first target information conversion rule and the receiving of the target information conversion rule in the method can be achieved by setting a communication method, and the set communication method may include Bluetooth communication, infrared communication, NFC communication, ultra wide band (UWB) communication, and the like.

[0199] The method can first determine a target information conversion rule supported by both the first terminal and the second terminal, and then convert the information to be transmitted into optical information based on the target information conversion rule, thereby achieving reliable transmission of the information to be transmitted through visible light.

[0200] In an exemplary embodiment, an information transmission method is provided, which is applied to a terminal. In the method, determining first spectrum information of first visible light may include:

[0201] S610, receiving instruction information;

[0202] S620. Determine first spectrum information according to the indication information.

[0203] In step S610, the indication information includes first indication information and / or second indication information, wherein the first indication information is indication information for determining the second visible light, and the second indication information is indication information for adjusting the second visible light.

[0204] The indication information may be input by a user to the first terminal so that the first terminal receives the indication information. The indication information may also be transmitted by another terminal (such as the second terminal) to the first terminal so that the first terminal receives the indication information.

[0205] When the indication information is transmitted from other terminals (such as the second terminal) to the first terminal, the transmission of the indication information can be achieved by setting a communication method, and the set communication method can include Bluetooth communication, infrared communication, NFC communication, ultra wideband (UWB) communication, etc.

[0206] Example 1,

[0207] The first terminal needs to transmit the information to be transmitted to the second terminal. Before transmitting the information to be transmitted, the user needs to input first indication information to the first terminal so that the first terminal can determine the target light parameter information, and then determine the second visible light used to carry the information to be transmitted based on the target light parameter information, and emit the second visible light to the second terminal so that the second terminal can receive the information to be transmitted.

[0208] During the transmission process of the information to be transmitted, if the second terminal determines that the received second visible light is unstable, it can send a second indication information to the first terminal to enable the first terminal to adjust the second visible light, that is, to enable the first terminal to redetermine the target light parameter information, and then redetermine the second visible light carrying the information to be transmitted, so as to better ensure the reliable transmission of the information to be transmitted.

[0209] The second visible light instability may include that the light intensity value of the optical signal received by the second terminal is too high or too low, or the light frequency value of the optical signal received by the second terminal is too high or too low, etc.

[0210] In this method, by setting the indication information, the target light parameter information can be adjusted in time according to the light conditions of the environment in which the first terminal is located, so as to adjust the second visible light, thereby ensuring that the information to be transmitted is transmitted reliably.

[0231] If the reference light intensity value is greater than the set intensity value, and among all the first light parameter groups, there is no light intensity value whose difference with the reference light intensity value is greater than or equal to the set threshold, then the first light parameter group with the smallest light intensity value among all the first light parameter groups is determined as the reference light parameter group; and / or,

[0232] If the reference light intensity value is greater than the set intensity value, and among all the first light parameter groups, there is a light intensity value whose difference with the reference light intensity value is greater than or equal to the set threshold, then the first light parameter group corresponding to the light intensity value is determined as the reference light parameter;

[0233] The reference light intensity value is the maximum light intensity value among all the light intensity values ​​of the first light parameter group.
