[0002] With the improvement of people's living standards, especially in daily laundry, a washer-dryer or a clothes dryer has become an indispensable part of the family, and the demand for clothes drying in the family is increasing.

[0003] Existing integrated washing and drying machines or clothes dryers mainly judge the dryness of clothes by temperature difference, but there may be inaccurate judgment during the dryness judgment process, so that the integrated washing and drying machine or clothes dryer may cause the clothes to be over-dried or stop drying when they are not completely dry. Among them, over-drying will damage the fibers and other tissues inside the clothes, thereby affecting the service life of the clothes. When the clothes are not completely dry, it will affect the user's experience. Summary of the invention

[0004] In view of this, the present invention provides a control method for judging whether clothes are dry, an electronic device, a computer-readable storage medium and a clothes processing device, so as to solve the problem that existing clothes processing devices such as a washer-dryer or a dryer may make inaccurate dryness judgments when drying clothes, thereby affecting the user experience.

[0005] A first aspect of an embodiment of the present invention provides a control method for judging whether clothes are dry, which is applied to a clothes processing device, wherein the clothes processing device includes a clothes processing barrel, and the control method for judging whether clothes are dry includes:

[0008] It is determined whether the flatness scores of the plurality of images of the load in the barrel meet the flatness requirement, and whether the flatness scores of the plurality of images of the load in the barrel meet the flatness requirement is used as a necessary condition for ending the drying process.

[0009] In some embodiments, whether the flatness scores of the plurality of images of the load in the barrel meet the flatness requirement includes:

[0010] Determining a value of an evaluation index according to the flatness scores of the plurality of images of the load in the barrel;

[0013] In some embodiments, the step of collecting a plurality of images of the load in the barrel during the drying process includes:

[0014] In the drying process, a plurality of images of the load in the barrel are obtained in at least two acquisition stages, and at least one image of the load in the barrel is obtained in each acquisition stage;

[0021] The average value of the updated evaluation index values ​​is compared with a threshold value of the evaluation index.

[0022] In some embodiments, when the value of the evaluation indicator is the variance mean, the threshold value of the evaluation indicator is 0.5.

[0023] In some embodiments, the flatness score is obtained by comparing the image of the load in the barrel with a standard flatness grade template.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0051] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0052] like Figure 1As shown, an exemplary embodiment of the present invention provides a clothes processing device 100. The clothes processing device may include but is not limited to a washing machine, and the washing machine may include but is not limited to a washing and care machine, a washing and drying machine, a clothes dryer, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with a drying or washing and care function, and of course, the washing machine may also be other types of fully automatic washing machines.

[0053] In this example and the following examples, the clothing processing device 100 is described by taking a washer-dryer or a clothes dryer as an example.

[0054] The laundry processing apparatus 100 includes a laundry processing tub 110 , and the laundry processing apparatus 100 can run a drying program to dry the laundry in the laundry processing tub 110 .

[0055] In some embodiments, the laundry processing device 100 may include one or two laundry processing tubs 110. Taking one laundry processing tub 110 as an example, a drying module (not shown in the figure) is arranged in the laundry processing tub 110, and the drying module includes a drying air duct, a drying fan and a drying element.

[0056] The air outlet and air inlet of the drying duct are both connected to the interior of the laundry processing barrel 110, and the drying fan and the drying element are both arranged in the drying duct. The drying element is configured to dehumidify and heat the hot and humid air drawn from the laundry processing barrel 110 to form a drying airflow to achieve drying of the laundry.

[0057] The drying element can be directly fixed in the drying air duct, or fixed in the drying air duct by other fasteners such as screws, etc. The drying element can be arranged at a position close to the air outlet of the drying air duct.

[0058] The drying element may include but is not limited to an electric heating wire or a PTC (Positive Temperature Coefficient, positive temperature coefficient thermistor) heater or other elements capable of heating air.

[0059] Along the flow direction of the drying airflow, the drying fan can be arranged upstream of the drying part. Through the rotation of the drying fan, on the one hand, the hot and humid gas drawn out from the clothes treatment barrel 110 can be guided to the drying part to form a drying airflow, and on the other hand, the drying airflow can also be driven into the clothes treatment barrel 110 to provide the clothes treatment barrel 110 with a suitable drying airflow to meet the demand for drying airflow when the clothes treatment barrel 110 is performing a drying operation. Alternatively, in the process of air-drying the clothes, or cooling the clothes treatment barrel 110 or the clothes in the later stage of the drying process, a suitable air volume is provided to meet the demand for air-drying the clothes, and the demand for cooling the clothes treatment barrel 110.

[0060] The drying fan may be a fan in the prior art, such as an induced draft fan or an axial flow fan.

[0061] It should be noted that the structure or specific setting position of the drying duct, drying fan and drying element in the drying module in this example is not specifically limited, as long as the drying duct, drying fan and drying element in the drying module can dry the clothes in the clothing processing barrel 110.

[0062] A temperature sensing bag (not shown in the figure) is arranged in the laundry treatment tub 110, and the temperature sensing bag may include a first temperature sensing bag and a second temperature sensing bag. The first temperature sensing bag is used to detect the temperature of the drying airflow entering the laundry treatment tub 110, that is, the inlet air temperature. The second temperature sensing bag is used to detect the temperature of the drying airflow discharged from the laundry treatment tub 110, that is, the outlet air temperature.

[0063] The first temperature sensing package and the second temperature sensing package may include but are not limited to a temperature sensor or a temperature and humidity sensor, etc. In addition, the number of the first temperature sensing package is at least one, and the number of the second temperature sensing package is at least one.

[0064] When there are multiple first temperature sensing bags and multiple second temperature sensing bags, the average value of the multiple detected inlet air temperatures can be used as the final inlet air temperature to improve the accuracy of inlet air temperature detection; and the average value of the multiple detected outlet air temperatures can be used as the final outlet air temperature to improve the accuracy of outlet air temperature detection.

[0065] Continue to refer to Figure 1 As shown, the laundry processing apparatus 100 includes a housing 120 , wherein a laundry processing tub 110 is disposed inside the housing 120 , and the laundry processing tub 110 is in the form of a drum and accommodated in a space constructed inside the housing 120 .

[0066] The housing 120 is provided with a display element 130, which may include but is not limited to a display. The display element 130 may be a display in the form of a button, for example, a program to be run by the clothing processing device 100 may be flexibly selected using a plurality of physical function buttons. Alternatively, the display element 130 may also be a display with a touch function, so that a program to be run by the clothing processing device 100 may be flexibly selected using a plurality of virtual buttons in the display.

[0067] It should be noted that the display element 130 can be set at any position of the housing 120. In a specific example, the display element 130 is set just above the opening of the laundry treatment tub 110, so that the user can put clothes through the opening of the laundry treatment tub 110, or take clothes out of the laundry treatment tub 110 from the opening. In the process of putting clothes into the laundry treatment tub 110 or taking clothes out of the laundry treatment tub 110, the display element 130 is set just above the opening, which can make it more convenient for the user to control the corresponding functions of the laundry treatment device.

[0068] In order to take pictures of the clothes in the clothes processing barrel 110 and judge the drying condition of the clothes by the flatness of the clothes surface, an image acquisition component 140 is provided in the clothes processing barrel 110, and the image acquisition component 140 may include but is not limited to a camera, a video camera, etc.

[0069] It should be noted that the image acquisition component 140 can take pictures of the clothes in the clothing processing barrel 110 during the clothing drying stage to obtain image information of the flatness of the clothing surface; on the other hand, after the image information of the clothes is obtained by the image acquisition component 140, the control system of the clothing processing device 100 can determine the specific material information of the clothes.

[0070] Among them, the control system of the clothing processing device 100 can adopt the control system in the prior art, as long as the control system can control various startup functions of the washer-dryer, and the specific structure type and specific control logic of the control system will not be repeated here.

[0071] A weight detection member (not shown) is also provided in the laundry treatment tub 110 or the laundry treatment device 100, wherein the weight detection member may include but is not limited to a weight sensor. The weight detection member can be used to detect the weight of the laundry in real time at any stage of the laundry treatment, such as before washing, after dehydration, and during drying.

[0072] like Figure 2 As shown, an exemplary embodiment of the present invention provides a method for controlling whether clothes are dry, and the method for controlling whether clothes are dry is applied to a clothes processing device 100. The method for controlling whether clothes are dry includes the following steps:

[0073] Step S100: collecting a plurality of images of the load in the laundry treatment tub during the drying process.

[0074] Step S200: performing flatness scoring on a plurality of in-barrel load graphics respectively to obtain a flatness score of each in-barrel load image.

[0075] Step S300: determining whether the flatness scores of the plurality of images of the load in the barrel meet the flatness requirement, and taking whether the flatness scores of the plurality of images of the load in the barrel meet the flatness requirement as a necessary condition for ending the drying process.

[0076] In step S100, when the clothing processing device 100 runs the drying program to dry the clothing, the control system determines that when the clothing reaches the dryness judgment condition, controls the image acquisition component 140 provided in the clothing processing barrel 110 to turn on, and photographs the clothing through the image acquisition component 140 to collect multiple load images of the clothing in the clothing processing barrel 110.

[0077] In one example, a camera disposed in the laundry treatment tub 110 may be used to continuously take pictures of the laundry to determine whether the laundry has been dried based on image information on the surface of the laundry.

[0078] Among them, before the clothes are dried after dehydration, or before the soaked clothes are dried, the surface of the clothes is easily affected by external forces and the temperature in the clothes processing barrel 110 in a wet state, and the ordered hydrogen bonds between the fiber molecules on the surface of the clothes are disrupted, thereby forming disordered hydrogen bonds. The wrinkles formed by the disordered hydrogen bonds cause the appearance of the surface of the clothes to be easily deformed.

[0079] During the drying process, water molecules will contact the hydrogen bonds between the fiber molecules on the surface of the clothes, and combine with the hydrogen bonds between the fiber molecules to form hydrogen bonds between the water molecules and the fiber molecules, thereby destroying the original wrinkles on the surface of the clothes. During the drying process, the disordered fiber molecules are pulled back to an orderly position by external pressure (such as the rotation speed and the rotation-stop ratio of the clothes processing barrel 110). Then, the drying airflow evaporates and dries the water molecules, so that the fiber molecules on the surface of the clothes form orderly hydrogen bonds again. When the water molecules are dried, the surface appearance of the clothes no longer changes. In other words, when the surface appearance of the clothes no longer changes, it indicates that the clothes have been dried.

[0080] Based on the above process, in one example, when the difference between the inlet temperature and the outlet temperature of the clothing processing barrel 110 is greater than the set value, the control system determines that the clothes in the clothing processing barrel 110 meet the dryness conditions. The set value can be flexibly set according to the material of the clothes, and is not specifically limited here.

[0081] When the material of the clothes is pure cotton fabric, the set value can be selected as 7°C. When the material of the clothes is silk fabric, the set value can be selected as 5°C.

[0082] When the control system determines that the clothes in the clothes processing barrel 110 meet the dryness determination condition, the control system controls the camera to start, and takes n consecutive photos of the clothes in the clothes processing barrel 110 in the same drying operation cycle, so as to collect multiple images of the load in the barrel of the clothes in the clothes processing barrel 110. Where n is a positive integer greater than or equal to 8.

[0083] In a preferred example, in order to ensure a complete wrinkle sample of the clothes in the clothes processing barrel 110, the control system controls the camera to take 10 consecutive photos of the clothes in the clothes processing barrel 110 during the same drying operation cycle, thereby obtaining 10 images of the load in the barrel, which are marked as S1, S2, S3, S4...S10 respectively.

[0084] In step S200, the flatness scores of the multiple barrel load images are respectively performed based on the control system and through image processing to obtain the flatness score corresponding to each barrel load image. The flatness score can be obtained by comparing the barrel load image with a standard flatness grade sample, that is, the barrel load image obtained by taking a photo is compared with the image of the standard sample card after image signal processing to obtain the score.

[0085] In one example, after collecting 10 consecutive barrel load images of clothes in the same drying cycle, each barrel load image is subjected to signal processing, and the barrel load image after signal processing is compared with a standard flatness grade template to obtain the flatness grade of the barrel load image, and output the flatness score representing the barrel load image, which are marked as s1, s2, s3, s4...s10 respectively.

[0086] In step S300, the control system determines whether the flatness scores of the multiple barrel load images meet the flatness requirements, and the flatness scores of the multiple barrel load images meeting the flatness requirements are used as a necessary condition for ending the drying process. Specifically, the variance of the 10 values ​​s1, s2, s3, s4, ... s10 obtained in the above step S200 is calculated, and the variance is recorded as X1. Among them, three cycles are recorded continuously, respectively recorded as X1, X2, and X3. Finally, the variance average of the three values ​​X1, X2 and X3 is calculated.

[0087] When the variance average of the three values ​​of X1, X2 and X3 is less than the threshold, it indicates that the flatness scores of the multiple images of the load in the barrel meet the flatness requirement, that is, the clothes in the laundry processing barrel 110 have been dried. At this time, the control system can control the laundry processing device 100 to stop running the drying program. The value of the threshold may include but is not limited to 0.5.

[0088] When the mean value of the variance of the three values ​​X1, X2 and X3 is greater than or equal to the threshold, it indicates that the clothes in the clothes processing barrel 110 have not been dried. At this time, the control system controls the clothes processing device 100 to continue running the drying program, and continues to obtain multiple images of the load in the barrel in the same drying operation cycle in the next acquisition stage through the camera, and judges the drying status of the clothes through the above steps S200 and S300, until the mean value of the variance of the three values ​​X1, X2 and X3 is less than the threshold, and then controls the clothes processing device 100 to stop running the drying program.

[0089] In this example, during the drying process, the clothes in the clothes processing barrel are continuously photographed so that the clothes can be judged to be dry based on the flatness of the clothes surface, thereby effectively improving the accuracy of judging the dryness of the clothes and enhancing the user experience of the clothes processing equipment.

[0090] like Figure 3 As shown, in some embodiments, the following method may be used to determine whether the flatness scores of multiple images of the load in the barrel meet the flatness requirement:

[0091] S310: Determine the value of the evaluation index according to the flatness scores of the plurality of images of the load in the barrel, wherein the evaluation index may include at least one of the average value, the variance average value, and the median value of the flatness scores of the plurality of images of the load in the barrel.

[0092] S320: Determine whether the flatness scores of the plurality of images of the load in the barrel meet the flatness requirement according to a magnitude relationship between a value of at least one evaluation indicator and a threshold value of the evaluation indicator.

[0093] In step S310 , after obtaining the flatness scores of the plurality of images of the load in the barrel, the control system determines the variance mean as the value of the evaluation index.

[0094] In one example, the control system takes 10 consecutive photos of the clothes in the clothes treatment barrel 110, and determines the flatness score of each load image in the barrel, such as s1, s2, s3, s4...s10. Then, the control system calculates the variance of the 10 values ​​of s1, s2, s3, s4...s10, and records the variance as X1. Among them, three cycles are recorded continuously, respectively recorded as X1, X2, and X3. Finally, the variance average of the three values ​​of X1, X2 and X3 is calculated.

[0095] It should be noted that the variance mean value may also be the mean value of other number of periods other than three periods, for example, four periods may be recorded continuously to obtain the variance mean value of the four periods.

[0096] For another example, five periods are recorded continuously to obtain the average value of the variance of the five periods.

[0097] Among them, the average value of the 10 flatness scores s1, s2, s3, s4, .....s10 can also be determined as the value of the evaluation index.

[0098] In another example, the control system takes 10 consecutive photos of the clothes in the clothes treatment barrel 110, and determines the flatness score such as s1, s2, s3, s4...s10 corresponding to each load image in the barrel. Then, the control system calculates the average value of the 10 flatness scores of s1, s2, s3, s4...s10, and records the average value as the first average value Y1. Among them, three cycles are recorded continuously, which are recorded as the first average value Y1, the second average value Y2, and the third average value Y3. Finally, the average value of the three values ​​of the first average value Y1, the second average value Y2, and the third average value Y3 is calculated.

[0099] It should be noted that the average value in this example may also be the average value of other number of periods other than three periods, for example, four periods are recorded continuously to obtain the average value of four periods.

[0100] For another example, five cycles are recorded continuously to obtain the average value of the five cycles.

[0101] In addition, the median value of the 10 flatness score values ​​s1, s2, s3, s4, ..., s10 may be determined as the value of the evaluation index.

[0102] In another example, the control system takes 10 consecutive photos of the clothes in the clothes processing barrel 110, and determines the flatness score of each load image in the barrel, such as s1, s2, s3, s4...s10. Then, the control system determines the median value of the 10 flatness score values ​​of s1, s2, s3, s4...s10, that is, the average value of the two flatness score values ​​s5 and s6 is taken as the median value, and the average value is recorded as the first median value Z1. Among them, three cycles are recorded continuously, respectively recorded as the first median value Z1, the second median value Z2, and the third median value Z3. Finally, the average value of the three values ​​of the first median value Z1, the second median value Z2, and the third median value Z3 is calculated, and the average value is taken as the median value.

[0103] It should be noted that the median value in this example may also be the median value of other number of periods other than three periods, for example, four periods are recorded continuously to obtain the median value of four periods.

[0104] For another example, five cycles are recorded continuously to obtain the median value of the five cycles.

[0105] In step S320, the control system uses any value of the variance mean, mean value and median value determined above as the value of the evaluation index. Then, the control system compares the value of the evaluation index with the threshold M of the evaluation index, and determines whether the flatness scores of the multiple images of the load in the barrel meet the flatness requirements based on the comparison results.

[0106] Among them, taking the value of the evaluation index as the variance mean as an example, the control system determines whether the flatness scores of multiple barrel load images meet the flatness requirements, and the flatness scores of the multiple barrel load images meeting the flatness requirements are used as a necessary condition for ending the drying process.

[0107] The variance of the 10 values ​​s1, s2, s3, s4 ... s10 obtained in the above step S310 is calculated, and the variance is recorded as X1. Among them, three cycles are recorded continuously, which are recorded as X1, X2, and X3 respectively. Finally, the variance average of the three values ​​X1, X2 and X3 is calculated.

[0108] When the variance average of the three values ​​of X1, X2 and X3 is less than the threshold M of the evaluation index, it indicates that the flatness scores of the multiple images of the load in the barrel meet the flatness requirements, that is, the clothes in the laundry treatment barrel 110 have been dried. At this time, the control system can control the laundry treatment device 100 to stop running the drying program. The value of the threshold M of the evaluation index may include but is not limited to 0.5.

[0109] When the mean value of the variance of the three values ​​X1, X2 and X3 is greater than or equal to the threshold value of the evaluation index, it indicates that the clothes in the clothes processing barrel 110 have not been dried. At this time, the control system controls the clothes processing device 100 to continue running the drying program, and continues to obtain multiple images of the load in the barrel in the same drying operation cycle in the next acquisition stage through the camera, and judges dryness again until the mean value of the variance of the three values ​​X1, X2 and X3 is less than the threshold value M of the evaluation index, and then controls the clothes processing device 100 to stop running the drying program.

[0110] like Figure 4 As shown, in some embodiments, the method for controlling the clothes to be judged dry includes the following steps:

[0111] Step S10: During the drying process, a plurality of images of the load in the barrel are acquired in at least two acquisition stages, and at least one image of the load in the barrel is acquired in each acquisition stage.

[0112] Step S20: Score the flatness of the load images acquired in each acquisition phase.

[0113] Step S30: For each acquisition stage, the value of the evaluation index is calculated according to the flatness score of the load image acquired in the acquisition stage.

[0114] Step S40: Compare the average value of the evaluation index corresponding to all acquisition stages with the threshold of the evaluation index. If it is less than the threshold of the evaluation index, determine that the flatness scores of the multiple images of the load in the barrel meet the flatness requirement, wherein the value of the evaluation index includes at least one of the average value, variance average value, and median value of the flatness score.

[0115] In step S10, when the clothes processing device 100 runs the drying program to dry the clothes, the control system determines that when the clothes reach the dryness determination condition, it controls the image acquisition component 140 set in the clothes processing barrel 110 to start. The control system controls the image acquisition component 140 to collect at least 5 or more images of the load in the barrel in each acquisition stage.

[0116] In step S20, the multiple barrel load images are scored for flatness based on the control system and through image processing to obtain a flatness score corresponding to each barrel load image. The flatness score can be obtained by comparing the barrel load image with a standard flatness grade sample, that is, the barrel load image obtained by taking a photo is compared with the image of the standard sample card after image signal processing to obtain a score.

[0117] In step S30, the control system determines any one of the average value, variance average value or median value of the flatness score as the value of the evaluation index. The process of determining the average value, variance average value or median value as the value of the evaluation index can refer to the above example and will not be repeated here.

[0118] In step S40, the control system compares the average value of the evaluation index corresponding to all acquisition stages with the threshold value M of the evaluation index. When the average value of the evaluation index is less than the threshold value M of the evaluation index, it is determined that the flatness scores of the multiple barrel load images meet the flatness requirement, that is, the clothes in the clothes processing barrel 110 have been dried, and at this time, the control system can control the clothes processing device 100 to stop running the drying program.

[0119] When the variance mean is used as the value of the evaluation index, the threshold M of the evaluation index is 0.5.

[0120] like Figure 4 As shown, in some embodiments, after step S40, the method for controlling the clothes to be dry further includes:

[0121] Step S50: When the average value of the evaluation index is greater than or equal to the threshold M of the evaluation index, obtain the value of the evaluation index of the new collection stage, remove the value of the evaluation index of the earliest collection stage, and recalculate the average value of the updated evaluation index.

[0122] Step S60: Compare the average value of the updated evaluation index value with the threshold value M of the evaluation index.

[0123] In step S50, when the control system determines that the average value of the evaluation index is greater than or equal to the threshold value M of the evaluation index, it indicates that the clothes in the clothing processing barrel 110 have not been dried. At this time, the control system controls the clothing processing device 100 to continue running the drying program, and continues to obtain multiple images of the load in the barrel in the same drying operation cycle in the next acquisition stage through the camera.

[0124] After reacquiring a plurality of images of the load in the bucket, the average value of the updated evaluation index is recalculated and obtained.

[0125] In step S60, the control system determines the average value of the updated evaluation index and compares it with the threshold value of the evaluation index until the average value of the updated evaluation index is less than the threshold value of the evaluation index, and then controls the clothing processing device 100 to stop running the drying program.

[0126] like Figure 5 As shown, in some embodiments, before collecting the load image in the barrel, the control method for judging whether the clothes are dry also includes the following method:

[0127] The control system detects and obtains the temperature difference between the inlet and outlet air of the load (i.e., clothes) in the laundry treatment barrel, which is the difference between the air inlet temperature T1 of the laundry treatment barrel 110 and the air outlet temperature T2 of the laundry treatment barrel 110 .

[0128] The inlet and outlet air temperature difference is compared with a preset dryness determination temperature difference, and when the inlet and outlet air temperature difference is less than or equal to the preset dryness determination temperature difference, an image of the load in the laundry treatment drum of the laundry is collected.

[0129] The preset dry temperature difference can be determined according to the parameters of the clothes in the clothes treatment barrel. The parameters may include but are not limited to weight and material. It should be noted that the preset dry temperature difference can be determined according to the parameters of the clothes by using the method in the prior art, which will not be repeated here.

[0130] An exemplary embodiment of the present invention provides an electronic device, which includes a processor (not shown in the figure) and a memory (not shown in the figure) connected to the processor.

[0131] The memory is used to store one or more computer executable instructions, wherein the computer executable instructions can be called by the processor to execute the control method for judging clothes dryness in the above embodiment.

[0132] An exemplary embodiment of the present invention provides a computer-readable storage medium, which stores computer instructions for causing a computer to execute the control method for judging whether clothes are dry in the above embodiment.

[0133] An exemplary embodiment of the present invention further provides a clothes processing device, which includes an image acquisition module and a drying determination module.

[0134] The image acquisition module is used to acquire multiple images of the load in the laundry processing barrel 110 of the laundry processing apparatus 100 during the drying process when the laundry processing apparatus 100 runs a drying program.

[0135] The drying judgment module is used to perform flatness scoring on multiple images of the load in the barrel respectively to obtain the flatness score corresponding to each image of the load in the barrel; it is also used to determine whether the flatness scores of the multiple images of the load in the barrel meet the flatness requirements, and take the flatness scores of the multiple images of the load in the barrel meeting the flatness requirements as a necessary condition for ending the drying process.

[0136] In the above example, during the drying process, the clothes in the clothes processing barrel 110 are continuously photographed to judge whether the clothes are dry based on the flatness of the clothes surface, thereby effectively improving the accuracy of judging whether the clothes are dry and improving the user experience of the clothes processing equipment.
