In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0023] See also Figure 1 The present invention provides an intelligent method for oil control based on spectral analysis and image recognition. The intelligent method for oil control based on spectral analysis and image recognition can be applied to a hair dryer to control the blowing mode of the hair dryer according to the oil content of the scalp. The intelligent method for oil control based on spectral analysis and image recognition includes S110-S140.

[0024] S110, controlled by a start instruction for starting the hair dryer, confirming a current working mode of the hair dryer.

[0025] In an embodiment of the present invention, a power button may be provided on the hair dryer, and the user can control the start and stop of the hair dryer through the power button. When the hair dryer is in the off state, the user can start the hair dryer by clicking the power button. At this time, the hair dryer receives the start instruction and starts to confirm the current working mode of the hair dryer.

[0026] The working mode can generally be divided into a traditional mode and an intelligent recognition mode. In the traditional mode, the user can manually adjust the blowing mode of the hair dryer. For example, multiple gears can be preset, and different gears correspond to different blowing modes, and different blowing modes correspond to different wind speeds and wind temperatures. It can be understood that the wind speed can include low speed, medium speed, and high speed, and the wind temperature can include low temperature, medium temperature, and high temperature. Different gears can be any combination of the above wind speeds and the above wind temperatures. For example, the first gear can be low speed and low temperature, the second gear can be medium speed and low temperature, and so on.

[0027] In intelligent identification mode, the hair dryer can intelligently identify the oil content of the scalp and adjust the blowing mode according to the oil content. For example, when the oil content is normal, the blowing mode can be high speed and high temperature. When the oil content is high, the blowing mode can be medium speed and medium temperature. When the oil content further increases, the blowing mode can be low speed and low temperature. That is, the higher the oil content, the lower the wind speed and temperature.

[0028] In addition, the working mode can be switched manually by the user, that is, a corresponding toggle switch can be provided on the hair dryer. When the toggle switch is in the off state, the hair dryer is in the traditional mode, and when the toggle switch is in the on state, the hair dryer is in the intelligent recognition mode.

[0029] S120: If the current working mode of the hair dryer is the intelligent recognition mode, the reflection intensity and characteristic image of the scalp are obtained.

[0030] In the embodiment of the present invention, the reflection intensity of the scalp refers to the intensity of the light reflected back from the scalp. For example, an infrared light or infrared-like light may be emitted toward the scalp, and then the hair dryer receives the reflected light reflected back from the scalp and analyzes the reflection intensity of the reflected light. Similarly, the hair dryer may be equipped with a camera module, which is used to capture the scalp image to obtain a feature image, and the feature information of the feature image may be analyzed to confirm the area of ​​the scalp containing oil. That is, the oil content may be preliminarily evaluated by the reflection intensity, and the area containing oil may be confirmed by the feature image.

[0031] S130: confirming the oil content of the scalp based on the reflection intensity and the characteristic image.

[0032] In the embodiment of the present invention, after the reflection intensity and the characteristic image are confirmed, the oil content of the scalp can be confirmed based on the reflection intensity and the characteristic image. The reflection intensity is generally the intensity of the reflected light, and the reflection area is usually smaller than the area captured by the characteristic image. The oil content of the reflection area can be used to estimate the oil content of the scalp in the characteristic image, thereby confirming the oil content of the user's scalp.

[0033] See also Figure 2 In some embodiments, such as in the present embodiment, the step S130 may include steps S131-S132.

[0034] S131, confirming the unit oil content of the scalp according to the reflection intensity, and confirming the area of ​​the scalp containing oil according to the characteristic image;

[0035] S132, calculating the fat content according to the unit fat content and the area of ​​the region.

[0036] In the embodiment of the present invention, the area of ​​the region refers to the area containing grease in the feature image, and the unit grease content refers to the grease content of a unit area in the area of ​​the region. The unit grease content can be calculated according to the first preset formula, that is, unit grease content = (reflection intensity - basic reflection intensity) / reflection coefficient, wherein the basic reflection intensity and the reflection coefficient are both constants. For example, if a certain reflection intensity is A, then substituting A into the first preset formula can obtain unit grease content = (A-basic reflection intensity) / reflection coefficient, and the basic reflection intensity and the reflection coefficient are both constants, and both can be an empirical value, so the unit grease content when the reflection intensity is A can be directly calculated.

[0037] After obtaining the unit fat content, the fat content can be obtained according to the second preset formula: fat content = unit fat content * area. For example, if the unit fat content is X and the area is Y, then the fat content = X*Y.

[0038] S140, adjusting the blowing mode of the hair dryer according to the oil content to reduce the oil content of the scalp.

[0039] In an embodiment of the present invention, after obtaining the oil content, the blowing mode of the hair dryer can be adjusted according to the oil content. The blowing mode of the hair dryer can be composed of different wind speeds and different wind temperatures. At the same time, an oil control spray module can be preset in the hair dryer. While adjusting the wind speed and temperature, it can also spray spray to reduce the oil content.

[0040] When adjusting the oil content, when the oil content is normal, the blowing mode can be high speed and high temperature; when the oil content is high, the blowing mode can be medium speed and medium temperature; when the oil content further increases, the blowing mode can be low speed and low temperature. That is, the higher the oil content, the lower the wind speed and temperature, so as to avoid further damage to the hair.

[0041] See also Figure 3 In some embodiments, such as in this embodiment, step S140 may include steps S141-S142.

[0042] S141, obtaining a preset oil control threshold and a preset wind speed and temperature adjustment threshold.

[0043] S142, adjusting the blowing mode of the hair dryer according to the oil content, the preset oil control threshold, and the preset wind speed and temperature adjustment threshold.

[0044] In the embodiment of the present invention, the preset oil control threshold is a condition for determining whether to start the oil control spray module, and the preset wind speed and wind temperature adjustment threshold is a condition for adjusting the wind speed and wind temperature. For example, when the oil content is greater than or equal to the preset oil control threshold, the oil control spray module is started, and when the oil content is less than the preset oil control threshold, the oil control spray module is turned off. The preset wind speed and wind temperature adjustment threshold may include multiple intervals, and the wind speed and wind temperature of the hair dryer are adjusted according to the different intervals into which the oil content falls.

[0045] See also Figure 4 In some embodiments, such as in this embodiment, step S142 may include steps S1421-S1422.

[0046] S1421, if the oil content is greater than or equal to the preset oil control threshold, start the oil control spray module, and control the oil control spray module to spray the scalp, and adjust the wind speed and wind temperature of the hair dryer according to the preset wind speed and wind temperature threshold;

[0047] S1422: If the oil content is less than the preset oil control threshold, the oil control spray module is turned off, and the wind speed and wind temperature of the hair dryer are adjusted according to the preset wind speed and wind temperature thresholds.

[0048] In an embodiment of the present invention, the preset oil control threshold is an empirical value, which is used to confirm whether it is necessary to start the oil control spray module. When the oil content is greater than or equal to the preset oil control threshold, the oil control spray module is started, and the scalp is sprayed with spray to reduce the oil content while the hair dryer is blowing. In addition, when the oil content is greater than or equal to the preset oil control threshold, the amount of spray sprayed by the oil control spray module can also be adjusted according to the percentage of the oil content exceeding the preset oil control threshold. For example, when the oil content exceeds the preset oil control threshold by 10%, 10 ml of spray is sprayed, and when the oil content exceeds the preset oil control threshold by 20%, 20 ml of spray is sprayed. That is, the percentage of the oil content exceeding the preset oil control threshold and the amount of spray spray can be linearly related. It can be understood that when spraying, it is only necessary to spray continuously once. After the predetermined amount is sprayed, the oil control spray module is turned off to facilitate the user to move the hair dryer.

[0049] The preset wind speed and temperature thresholds are used to adjust the wind speed and wind temperature of the hair dryer, which may include multiple intervals, for example, a first interval, a second interval, and a third interval, and the upper limit of the first interval is less than the lower limit of the second interval, and the upper limit of the second interval is less than the lower limit of the third interval. When the grease content is in the first interval, the hair dryer is low speed and low temperature, when the grease content is in the second interval, the hair dryer is medium speed and medium temperature, and when the grease content is in the third interval, the hair dryer is high speed and high temperature. It can be understood that the blowing mode mainly adjusts the wind speed and temperature according to the grease content, and it is not limited to the above corresponding method.

[0050] See also Figure 5 In some embodiments, such as in the present embodiment, the method may include steps S150-S170.

[0051] S150, when in the intelligent recognition mode, confirming whether a target image is detected, wherein the target image includes scalp information;

[0052] S160, if the target image is detected, emitting infrared light and receiving reflected light reflected by the infrared light;

[0053] S170, analyzing the reflected light to obtain the reflected intensity.

[0054] In an embodiment of the present invention, when the hair dryer detects the target image, that is, the hair dryer is facing the scalp and can work, it can emit infrared light to the scalp, receive reflected light reflected by the scalp, and then obtain the reflection intensity based on the reflected light.

[0055] See also Figure 6 In some embodiments, such as in the present embodiment, the method may include step S180.

[0056] S180: If the target image is detected, color extraction is performed on the target image to generate the feature image.

[0057] In the embodiment of the present invention, while emitting infrared light, the target image is also subjected to color extraction to generate a feature image, and then it is confirmed whether there is a certain area in the feature image whose color is consistent with the color of the preset color parameter area, and the area in the feature image that is consistent with the color of the preset color parameter area is set as the target area, and then the area of ​​the target area is calculated. That is, the preset color parameter area is generated based on the color of the scalp covered with oil, and is used to confirm the area on the scalp that contains oil.

[0058] See also Figure 7 In some embodiments, such as in the present embodiment, the method may include step S190.

[0059] S190: If the target image is not detected, adjusting the blowing mode to a default mode.

[0060] In an embodiment of the present invention, when the target image is not detected, that is, the hair dryer cannot capture the scalp information, the blowing mode can be adjusted to the default mode. In the default mode, the wind speed and temperature of the hair dryer can be medium wind and medium temperature.

[0061] The present invention also provides a hair dryer, which includes a detection module, an oil control spray module and a control module; the detection module is used to detect the scalp to obtain reflection intensity and characteristic images; the oil control spray module is used to spray spray to reduce the oil content of the scalp; the control module is used to adjust the blowing mode and the start and stop of the oil control spray module according to the reflection intensity and the characteristic image.

[0062] Specifically, the detection module is used to detect the scalp to obtain the reflection intensity and characteristic image. For example, an infrared light or infrared-like light can be emitted toward the scalp, and then the hair dryer receives the reflected light reflected from the scalp and analyzes the reflection intensity of the reflected light. Similarly, the hair dryer can be equipped with a camera module, which is used to take the scalp image to obtain the characteristic image, and the characteristic information of the characteristic image can be analyzed to confirm the area of ​​the scalp containing oil. That is, the oil content can be preliminarily evaluated by the reflection intensity, and the area containing oil can be confirmed by the characteristic image.

[0063] The oil control spray module may store an essence, which is used to reduce the oil content. When receiving the command of the control module, the essence starts to be sprayed. The control module is used to adjust the blowing mode and the start and stop of the oil control spray module according to the reflection intensity and the characteristic image. For example, a preset oil control threshold may be provided, and the oil control threshold is set as a condition for determining whether to start the oil control spray module, and the preset wind speed and wind temperature adjustment threshold is a condition for adjusting the wind speed and wind temperature. For example, when the oil content is greater than or equal to the preset oil control threshold, the oil control spray module is started, and when the oil content is less than the preset oil control threshold, the oil control spray module is turned off. The preset wind speed and wind temperature adjustment threshold may include multiple intervals, and the wind speed and wind temperature of the hair dryer are adjusted according to the different intervals into which the oil content falls.

[0064] The intelligent method and hair dryer for achieving oil control based on spectral analysis and image recognition disclosed in the present invention can identify the oil content of the user's scalp and adjust the blowing mode of the hair dryer according to the oil content to avoid damage to the scalp and reduce the oil content.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
