[0002] Infrared light therapy, as a new method of irradiating with infrared lamps, has been widely used in the fields of rehabilitation medicine, beauty care, etc. in recent years due to its advantages such as non-invasive and low side effects. Its basic principle is to utilize the penetration ability of infrared light on human tissues to promote blood circulation, accelerate tissue repair, and relieve pain and other symptoms. Infrared light therapy devices usually include infrared light sources. By adjusting factors such as the power, irradiation time, and distance of the light source, the temperature and light intensity of the irradiated area of the infrared lamp can be controlled, so as to achieve the infrared lamp irradiation effect.

This solves the problem that traditional devices have limitations in adjusting the irradiation distance, irradiation energy, etc., making the optimization of the infrared lamp irradiation parameters simpler and more reliable. Brief Description of the Drawings

[0088] Figure 1 The figure is a schematic flowchart of the method according to an embodiment of the present application.

[0089] Figure 2 The figure is a schematic structural diagram of the system according to an embodiment of the present application.

[0090] The realization, functional characteristics and advantages of the purpose of the present application will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiments

[0091] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0092] As Figure 1 shown, the present application provides an energy control method for a light therapy bed in a space capsule, including:

[0093] S1. Obtain the real-time irradiation distances of multiple infrared lamps of the light therapy bed, and obtain the first irradiation energy value of the corresponding infrared lamp according to each real-time irradiation distance;

[0094] S2. Obtain the real-time irradiation light spot corresponding to the infrared lamp according to the first irradiation energy value;

[0095] S3. Obtain the skin absorbance corresponding to the position of the real-time irradiation light spot;

[0096] S4. Obtain area division information according to the real-time irradiation light spot, wherein the area division information includes an outer circle sampling area, a middle circle sampling area and an inner circle sampling area;

[0097] S5. Obtain a light spot change value according to the skin absorbance, the outer circle sampling area, the middle circle sampling area and the inner circle sampling area;

[0098] S6. Judge whether the light spot change value corresponding to each infrared lamp is within a preset interval;

[0099] If not, obtain the corresponding second irradiation energy value according to the light spot change value not within the preset interval, and adjust the infrared lamp corresponding to the light spot change value of the second irradiation energy value.

[0100] As described in the above steps S1 - S6, existing infrared light therapy devices lack a real - time feedback mechanism and it is difficult to dynamically adjust irradiation parameters according to individual differences of users (such as skin color, distance from different body parts to the infrared lamp, etc.). During the infrared lamp irradiation process, once the distance between the light source and the skin changes, or the skin absorbance is different, the device cannot make timely adjustments, which may lead to poor irradiation effects of the infrared lamp. For example, there are limitations in adjusting the irradiation distance, irradiation energy, etc., and it is difficult to flexibly adjust according to the real - time monitored data. For instance, when the user moves, the distance between the light source and the skin changes, but the device cannot immediately adjust the irradiation intensity or spot size, resulting in the inability to optimize the set parameters of the infrared lamp in a timely manner. When the spot is uneven, it may cause some areas to overheat while other areas are not effectively irradiated, thus reducing the irradiation effect of the infrared lamp;

[0101] The present invention ensures that the distance between the light source and the body part always meets the appropriate distance by real - time monitoring the distance between the infrared lamp and the skin, avoiding the problem of unstable irradiation effects caused by distance changes. It dynamically adjusts the first irradiation energy value of the infrared lamp according to the real - time obtained distance information, ensuring that the energy output of each infrared lamp matches the current distance of the body part. Then, by adjusting the irradiation energy value of the infrared lamp, it ensures that the spot size generated by each infrared lamp is moderate, neither too large nor too small, and can cover the area to be irradiated, making the irradiation spot evenly distributed in the irradiation area, avoiding local overheating or other adverse reactions, and improving the irradiation effect. It solves the technical problem that in the prior art, if the distance between the light source and the skin changes, traditional devices cannot make timely adjustments, which may lead to too high or too low irradiation energy, affecting the irradiation effect. By measuring the skin absorbance and adjusting the irradiation parameters according to the skin characteristics of different users (such as skin color depth), it ensures that each user can obtain the most suitable irradiation intensity, realizing personalized infrared lamp irradiation. Then, the irradiation spot is divided into different regions to facilitate separately monitoring the irradiation conditions of each region, ensuring that the infrared lamp in each region can achieve the ideal irradiation effect. Through regional division, fine - tuning can be carried out according to the characteristics of different regions, improving the overall effect of infrared lamp irradiation. By combining the skin absorbance and the irradiation conditions of different regions, comprehensively evaluating the changes of the spot, ensuring the uniform distribution of the spot during the infrared lamp irradiation process. Through preset interval judgment, it can intelligently decide whether adjustment is needed, reducing the workload of the operator. By calculating the spot adjustment value to obtain a new irradiation energy value, it ensures that the irradiation energy of each infrared lamp is accurately adjusted to the ideal state. Finally, a closed - loop control system is formed to optimize the infrared lamp irradiation effect by continuously adjusting the irradiation energy value, ensuring that the infrared lamp irradiation process always maintains the best state, and solving the technical problem that existing devices cannot adjust the irradiation energy in real time according to the actual situation, resulting in unstable infrared lamp irradiation effects.

[0102] In one embodiment, the step of obtaining the first irradiation energy value of the corresponding infrared lamp according to each of the real-time irradiation distances includes:

[0103] S201. Obtain the infrared light signal and the infrared lamp dark signal from the infrared lamp configuration table according to the real-time irradiation distance;

[0104] S202. Convert the infrared light signal to obtain the first infrared lamp gray value;

[0105] S203. Convert the infrared lamp dark signal to obtain the second infrared lamp gray value;

[0106] S204. Obtain the preset photoelectric conversion efficiency of the infrared lamp;

[0107] S205. Obtain the number of infrared lamp photons according to the preset photoelectric conversion efficiency, the first infrared lamp gray value, and the second infrared lamp gray value;

[0108] S206. Obtain the acquisition time of the infrared sensor under light;

[0109] S207. Obtain the first irradiation energy value according to the preset photoelectric conversion efficiency, the number of infrared lamp photons, and the acquisition time.

[0110] As described in the above steps S201-S207, the present invention solves the problem that traditional devices are difficult to adjust the irradiation parameters according to the distance change between the user and the light source during the infrared lamp irradiation process by obtaining the infrared light signal and the infrared lamp dark signal from the infrared lamp configuration table according to the real-time irradiation distance, ensuring that the distance change between the light source and the skin during the infrared lamp irradiation process does not affect the irradiation effect, and at the same time ensuring that the light source signal can be accurately matched according to the current actual distance, improving the irradiation accuracy; and converting the infrared light signal to obtain the first infrared lamp gray value, standardizing the problem that the original light signal forms are diverse and difficult to directly use for comparison and analysis, which is convenient for unified processing after being converted into a gray value, improving the system stability and reliability; then converting the infrared lamp dark signal to obtain the second infrared lamp gray value, eliminating the influence of background noise on the measurement result by obtaining and converting the dark signal, improving the signal-to-noise ratio, and the data after removing the dark signal is more pure, which helps to improve the authenticity and reliability of the signal and avoid misjudgment caused by noise interference; obtaining the preset photoelectric conversion efficiency of the infrared lamp to ensure consistent performance under different conditions, improving the repeatability of the measurement result, providing a basis for subsequent calculations, and ensuring the accuracy and reliability of the calculation result; obtaining the number of infrared lamp photons according to the preset photoelectric conversion efficiency, the first infrared lamp gray value, and the second infrared lamp gray value, and the specific calculation formula for the number of infrared lamp photons is:

[0111] N = (G1 - G2) / ρ;

[0112] Wherein, N is the number of infrared light photons, G1 is the gray value of the first infrared lamp, G2 is the gray value of the second infrared lamp, and ρ is the photoelectric conversion efficiency; the number of photons is calculated through the photoelectric conversion efficiency and the gray value, improving the accuracy and reliability of the calculation result. By combining the gray value and the photoelectric conversion efficiency, the integrity and authenticity of the data are ensured; by obtaining the acquisition time of the infrared sensor under light, the consistency of the acquisition time is ensured, improving the comparability and reliability of the data. The accurate recording of the acquisition time helps to precisely control the irradiation time and energy, solving the problem that the lack of consistency between the data collected by traditional devices at different time periods affects the result comparability; then, according to the preset photoelectric conversion efficiency, the number of infrared light photons, and the acquisition time, the first irradiation energy value is obtained. The specific calculation formula of the first irradiation energy value is:

[0113] E = ρ * N * T;

[0114] Wherein, E is the first irradiation energy value, ρ is the photoelectric conversion efficiency, and T is the acquisition time; by comprehensively considering the photoelectric conversion efficiency, the number of photons, and the acquisition time, the irradiation energy value is accurately calculated, ensuring the accuracy and reliability of the final energy value, solving the problem that traditional devices may cause inaccurate energy calculation due to incomplete consideration of a single factor. Through the comprehensive calculation of multiple factors, the accuracy of energy calculation is ensured. Thus, through the above steps, more precise energy control can be achieved, ensuring the effect of infrared lamp irradiation, and at the same time providing a more personalized infrared lamp irradiation scheme, thereby better serving the health needs of users.

[0115] In one embodiment, the step of obtaining the real-time irradiation spot corresponding to the infrared lamp according to the first irradiation energy value includes:

[0116] S301. Obtain the real-time irradiation distance;

[0117] S302. Obtain the irradiance of the infrared lamp according to the first irradiation energy value, and obtain the first irradiation intensity value according to the irradiance;

[0118] S303. Obtain the first divergence angle value at the infrared light source of the infrared lamp under the first irradiation intensity value;

[0119] S304. Obtain the second divergence angle value of the irradiation spot of the infrared lamp according to the first divergence angle value;

[0120] S305. Obtain the diameter of the irradiation spot of the infrared lamp according to the real-time irradiation distance and the second divergence angle value;

[0121] S306. Obtain the center coordinates of the infrared lamp, and position the irradiation spot according to the center coordinates to obtain the real-time irradiation spot.

[0122] As described in the above steps S301 - S306, the present invention solves the problem that traditional devices are difficult to adjust the irradiation parameters according to the distance change between the user and the light source during the infrared lamp irradiation by obtaining the real - time irradiation distance, ensuring that the distance change between the light source and the skin during the infrared lamp irradiation does not affect the infrared lamp irradiation effect, and at the same time ensuring that the system can accurately match the light source signal according to the current actual distance, improving the irradiation accuracy. The advantage of this step is that it can monitor the distance between the light source and the skin in real - time, ensuring that the distance change between the light source and the skin can be captured in time, thereby providing a basis for subsequent adjustment of irradiation parameters and solving the problem that traditional devices have too high or too low irradiation energy due to distance changes; In step S302, the irradiance of the infrared lamp is obtained according to the first irradiation energy value, and the first irradiation intensity value obtained according to the irradiance solves the problem that traditional devices are difficult to ensure uniform spot distribution. The advantage of this step is that it can ensure uniform spot distribution by calculating the irradiance and irradiation intensity value, avoiding local overheating or other adverse reactions. By accurately calculating the irradiance and irradiation intensity value, it can ensure that the spot size generated by each infrared lamp is moderate, neither too large nor too small, and can cover the infrared lamp irradiation area, making the irradiation spot evenly distributed in the infrared lamp irradiation area and avoiding local overheating or other adverse reactions; In step S303, the first divergence angle value at the infrared light source is obtained under the first irradiation intensity value, solving the problem that traditional devices have limitations in adjusting the irradiation distance, irradiation energy, etc. The advantage of this step is that by obtaining the divergence angle value, the shape and size of the spot can be better controlled, ensuring the uniform distribution of the spot in the infrared lamp irradiation area, improving the infrared lamp irradiation effect. Through regional division, fine - tuning can be carried out according to the characteristics of different regions, improving the overall effect of infrared lamp irradiation, making the irradiation spot evenly distributed in the infrared lamp irradiation area and avoiding local overheating or other adverse reactions; In step S304, the second divergence angle value of the infrared lamp irradiation spot is obtained according to the first divergence angle value. Although there is a repeated expression here, it actually means confirming and utilizing the divergence angle value to further optimize the irradiation parameters, solving the problem that traditional devices are difficult to make fine - tuning according to the irradiation requirements of different regions. By continuously adjusting the irradiation parameters, local overheating or other adverse reactions are avoided; In step S305, the irradiation spot diameter of the infrared lamp is obtained according to the real - time irradiation distance and the second divergence angle value, solving the problem that the uniformity of the spot needs to be ensured during the infrared lamp irradiation. The advantage of this step is that by adjusting the irradiation spot diameter in real - time, local overheating or other adverse reactions are avoided. By adjusting the irradiation spot diameter in real - time;In step S306, the central coordinates of the infrared lamp are obtained, and the real-time irradiation spot is located based on the central coordinates. The advantage of this step is that by precisely controlling the irradiation energy of each infrared lamp and adjusting according to parameters such as skin absorbance and spot change value, side effects caused by uneven irradiation can be avoided. By precisely controlling the irradiation energy of each infrared lamp and adjusting according to parameters such as skin absorbance and spot change value, side effects caused by uneven irradiation can be avoided. Through the above steps, the infrared light therapy technology can achieve more precise energy control.

[0127] S404. Obtain the skin thickness of the skin in the real-time irradiation spot area;

[0128] S405. Calculate the skin absorbance according to the transmitted light intensity value, incident light intensity value, absorption coefficient and skin thickness. The calculation formula is:

[0129]

[0130] where G is the skin absorbance, T x is the transmitted light intensity value, T y is the incident light intensity value, d is the skin thickness, and σ is the absorption coefficient.

[0131] As described in the above steps S401 - S405, the present invention solves the problem that traditional devices are difficult to dynamically adjust irradiation parameters according to individual differences of users (such as skin color, distance from different body parts to the infrared lamp, etc.) by obtaining the transmitted light intensity value of the skin in the real - time irradiated spot area. The advantage of this step is that it can monitor the transmitted light intensity of the skin in real - time, ensuring that the change in the distance between the light source and the skin does not affect the irradiation effect of the infrared lamp. At the same time, it ensures that the system can accurately match the light source signal according to the current actual distance, improving the irradiation accuracy and solving the problem that traditional devices have too high or too low irradiation energy due to distance changes; Step S402 obtains the incident light intensity value of the skin in the real - time irradiated spot area, solving the problem that traditional devices are difficult to ensure uniform spot distribution. The advantage of this step is that by obtaining the incident light intensity value, the absorbance of the skin can be accurately calculated, avoiding local overheating or other adverse reactions. By accurately calculating the incident light intensity value, it ensures that the spot size generated by each infrared lamp is appropriate, neither too large nor too small, so that the irradiated spots are evenly distributed in the infrared lamp irradiation area, avoiding local overheating or other adverse reactions; Step S403 obtains the absorption coefficient of the skin in the real - time irradiated spot area, solving the problem that traditional devices have limitations in adjusting irradiation distance, irradiation energy, etc. The advantage of this step is that by obtaining the absorption coefficient, the shape and size of the spot can be better controlled, and through regional division, fine - tuning can be carried out according to the characteristics of different regions; Step S404 obtains the skin thickness of the skin in the real - time irradiated spot area, solving the problem that it is necessary to ensure the uniformity of the spot during the infrared lamp irradiation process. The advantage of this step is that by adjusting the diameter of the irradiated spot in real - time, it ensures the uniform distribution of the spot in the infrared lamp irradiation area, avoiding local overheating or other adverse reactions. By adjusting the diameter of the irradiated spot in real - time; Step S405 calculates the skin absorbance according to the transmitted light intensity value, incident light intensity value, absorption coefficient and skin thickness. The advantage of this step is that by precisely controlling the irradiation energy of each infrared lamp and adjusting according to parameters such as skin absorbance and spot change value, side effects caused by uneven irradiation are avoided. Suppose there is a specific example:

[0132] Obtain the transmitted light intensity value T of the skin in the real - time irradiated spot area x :

[0133] Suppose the transmitted light intensity value is 50 mW / cm 2 .

[0134] Obtain the incident light intensity value T of the skin in the real - time irradiated spot area y :

[0135] Suppose the incident light intensity value is 200 mW / cm 2 .

[0136] Obtain the absorption coefficient σ of the skin in the real - time irradiated spot area:

[0137] Assume the absorption coefficient is 0.01 cm.

[0138] Obtain the skin thickness d of the skin in the area of the real-time irradiation spot:

[0139] Assume the skin thickness is 2 mm or 0.2 cm.

[0140] Based on the above values, we can calculate the skin absorbance The skin absorbance is approximately 0.602. This value reflects the degree to which light is absorbed when passing through the skin. In this way, we can calculate the skin absorbance based on the actually measured data, and then better understand the propagation of light in the skin during phototherapy. By precisely controlling the irradiation energy of each infrared lamp and adjusting according to parameters such as skin absorbance and spot change value, side effects caused by uneven irradiation can be avoided. Through the above steps, the infrared phototherapy technology can achieve more precise energy control and at the same time provide a more personalized infrared lamp irradiation scheme.

[0141] In one embodiment, the step of obtaining area division information according to the real-time irradiation spot includes:

[0142] S501. Obtain the spot center coordinates of the real-time irradiation spot by the centroid method;

[0143] S502. Obtain the irradiation spot radius according to the irradiation spot diameter, and take the circular area from the spot center coordinates to one-third of the irradiation spot radius as the inner circle sampling area;

[0144] S503. Take the annular area from one-third of the irradiation spot radius to two-thirds of the irradiation spot radius as the middle circle sampling area;

[0145] S504. Take the annular area from two-thirds of the irradiation spot radius to the outer circle of the irradiation spot as the outer circle sampling area.

[0146] As described in the above steps S501 - S504, the present invention obtains the spot center coordinates of the real - time irradiation spot through the centroid method, solving the problem that traditional devices are difficult to dynamically adjust irradiation parameters according to individual differences of users (such as skin color, distance of body parts, etc.). The advantage of this step is that it can monitor and accurately locate the center coordinates of the spot in real - time, ensuring that the change in the distance between the light source and the skin does not affect the infrared lamp irradiation effect. At the same time, it ensures that the system can accurately match the light source signal according to the current actual distance, improving the irradiation accuracy. By obtaining the spot center coordinates in real - time, the system can ensure that the infrared lamp irradiation area is always within the optimal irradiation range, avoiding the problem of uneven irradiation caused by the change in the distance between the light source and the skin; In step S502, the irradiation spot radius is obtained according to the irradiation spot diameter, and the circular area from the spot center coordinates to one - third of the irradiation spot radius is used as the inner - circle sampling area, solving the problem that traditional devices are difficult to ensure uniform spot distribution. The advantage of this step is that by dividing the spot area into different sampling areas, the shape and size of the spot can be better controlled, ensuring the uniform distribution of the spot within the infrared lamp irradiation area. Through area division, fine - tuning can be carried out according to the characteristics of different areas, improving the overall effect of infrared lamp irradiation, making the irradiation spot evenly distributed in the infrared lamp irradiation area, and avoiding local overheating or other adverse reactions; In step S503, the annular area from one - third of the irradiation spot radius to two - thirds of the irradiation spot radius is used as the middle - circle sampling area, solving the problem of ensuring the uniformity of the spot during the infrared lamp irradiation process. The advantage of this step is that by adjusting the irradiation spot diameter in real - time, local overheating or other adverse reactions can be avoided. By further subdividing the irradiation area, the spot uniformity of different areas can be monitored more accurately, so as to timely adjust the position or intensity of the light source, ensuring the uniform distribution of the spot within the entire infrared lamp irradiation area; In step S504, the annular area from two - thirds of the irradiation spot radius to the outer circle of the irradiation spot is used as the outer - circle sampling area. The advantage of this step is that by precisely controlling the irradiation energy of each infrared lamp and adjusting according to parameters such as skin absorbance and spot change value, side effects caused by uneven irradiation can be avoided. By separately sampling the outer - circle area, it can be ensured that the edge of the infrared lamp irradiation area is also sufficiently irradiated, preventing poor irradiation effect of the infrared lamp in the edge area. Through the above steps, the infrared light therapy technology can achieve more precise energy control and provide a more personalized infrared lamp irradiation plan, thus better serving the health needs of users. By precisely dividing different areas of the irradiation spot, the system can monitor and adjust irradiation parameters in real - time, ensuring that the change in the distance between the light source and the skin during the infrared lamp irradiation process does not affect the infrared lamp irradiation effect, and at the same time adjusting irradiation parameters according to the characteristics of the skin, ensuring the uniform distribution of the spot within the infrared lamp irradiation area, avoiding local overheating or other adverse reactions, and thus improving the overall effect of infrared lamp irradiation.

[0147] In one embodiment, the step of obtaining the spot change value according to the skin absorbance, the outer ring sampling area, the middle ring sampling area, and the inner ring sampling area includes:

[0148] S601. Obtain the skin absorbance;

[0149] S602. Obtain a plurality of evenly distributed outer ring pixel points according to the outer ring sampling area, and obtain a first gray average value according to the plurality of outer ring pixel points;

[0150] S603. Obtain a plurality of evenly distributed middle ring pixel points according to the middle ring sampling area, and obtain a second gray average value according to the plurality of middle ring pixel points;

[0151] S604. Obtain an inner ring pixel point according to the inner ring sampling area, and obtain a third gray average value according to the inner ring pixel point;

[0152] S605. Obtain the spot gray average value according to the first gray average value, the second gray average value, and the third gray average value;

[0153] S606. Obtain a preset gray average value from the infrared lamp configuration table according to the real-time irradiation distance;

[0154] S607. Calculate the spot change value according to the spot gray average value and the preset gray average value, where the calculation formula is:

[0155]

[0156] where K is the spot change value, V i is the preset gray average value, V l is the spot gray average value, and e is a constant.

[0157] As described in the above steps S601 - S607, the present invention obtains the skin absorbance, which solves the problem that traditional devices are difficult to dynamically adjust the irradiation parameters according to individual differences of users (such as skin color, distance of body parts, etc.). The advantage of this step is that it can monitor the skin absorbance in real time, ensure that the change in the distance between the light source and the skin does not affect the infrared lamp irradiation effect, and at the same time ensure that the system can accurately match the light source signal according to the current actual distance, improving the irradiation accuracy. By obtaining the skin absorbance in real time, the system can ensure that the infrared lamp irradiation area is always within the optimal irradiation range, avoiding the problem of uneven irradiation caused by the change in the distance between the light source and the skin; In step S602, multiple evenly distributed outer - circle pixel points are obtained according to the outer - circle sampling area, and the first gray - scale average value is obtained based on the multiple outer - circle pixel points, which solves the problem that traditional devices are difficult to ensure uniform spot distribution. The advantage of this step is that by obtaining multiple evenly distributed outer - circle pixel points, the shape and size of the spot can be better controlled, ensuring the uniform distribution of the spot within the infrared lamp irradiation area. Through regional division, fine - tuning can be carried out according to the characteristics of different regions, improving the overall effect of infrared lamp irradiation, making the irradiation spot evenly distributed within the infrared lamp irradiation area, and avoiding local overheating or other adverse reactions; In step S603, multiple evenly distributed middle - circle pixel points are obtained according to the middle - circle sampling area, and the second gray - scale average value is obtained based on the multiple middle - circle pixel points, which solves the problem of ensuring the uniformity of the spot during the infrared lamp irradiation process. The advantage of this step is that by adjusting the irradiation spot diameter in real time, local overheating or other adverse reactions can be avoided. By further subdividing the irradiation area, the spot uniformity of different regions can be monitored more accurately, so as to timely adjust the position or intensity of the light source, ensuring the uniform distribution of the spot within the entire infrared lamp irradiation area; In step S604, an inner - circle pixel point is obtained according to the inner - circle sampling area, and the third gray - scale average value is obtained based on the inner - circle pixel point. The advantage of this step is that by precisely controlling the irradiation energy of each infrared lamp and adjusting according to parameters such as skin absorbance and spot change value, side effects caused by uneven irradiation can be avoided. By separately sampling the outer - circle area, it can be ensured that the edge of the infrared lamp irradiation area also receives sufficient irradiation, preventing poor irradiation effect of the infrared lamp in the edge area. In step S605, the spot gray - scale average value is obtained according to the first gray - scale average value, the second gray - scale average value, and the third gray - scale average value. The advantage of this step is that by calculating the spot gray - scale average value, the uniformity of the spot can be more accurately evaluated;In step S606, the preset gray - scale average value is obtained from the infrared lamp configuration table according to the real - time irradiation distance, which solves the problem that traditional devices are difficult to make fine - tuning according to the irradiation requirements of different regions. The advantage of this step is that by obtaining the preset gray - scale average value, the system can dynamically adjust the irradiation parameters according to the actual irradiation distance, ensuring that the change in the distance between the light source and the skin during the infrared lamp irradiation does not affect the irradiation effect of the infrared lamp. At the same time, it ensures that the system can accurately match the light source signal according to the current actual distance, improving the irradiation accuracy. In step S607, the spot change value is calculated based on the spot gray - scale average value and the preset gray - scale average value. The advantage of this step is that by calculating the spot change value, the system can monitor the uniformity of the spot in real - time, avoiding local overheating or other adverse reactions.

[0158] Suppose we have an actual phototherapy scenario where we need to calculate the spot change value to determine whether to adjust the irradiation energy of the infrared lamp:

[0159] Obtain the spot gray - scale average value V i :

[0160] Suppose the gray - scale average value of the current spot obtained through image processing is V i = 120;

[0161] Suppose the preset gray - scale average value is V l = 100;

[0162] Suppose the constant C is set to 100 (this constant can be adjusted according to actual needs, and the unit is usually a percentage);

[0163] Substitute the above data into the K calculation formula, and we get K = 20. 20 means that the difference between the gray - scale average value of the current spot and the preset gray - scale average value accounts for 20% of the preset value. According to the actual situation, if the gray - scale average value of the current spot is higher than the preset value, the irradiation energy may need to be reduced; if it is lower than the preset value, the irradiation energy needs to be increased. Through the above steps, the infrared phototherapy technology can achieve more precise energy control and provide a more personalized infrared lamp irradiation plan, thus better serving the health needs of users. By accurately dividing different regions of the irradiation spot, the system can monitor and adjust the irradiation parameters in real - time, ensuring that the change in the distance between the light source and the skin during the infrared lamp irradiation does not affect the irradiation effect of the infrared lamp, and at the same time adjusting the irradiation parameters according to the characteristics of the skin.
