Detailed Description
First, it should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications.
Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The terms to which the present invention relates will be explained first:
1) the intelligent household appliance equipment is a household appliance product formed by introducing a microprocessor, a sensor technology and a network communication technology into the household appliance equipment, has the characteristics of intelligent control, intelligent perception and intelligent application, and the operation process of the intelligent household appliance equipment usually depends on the application and processing of modern technologies such as the Internet of things, the Internet and an electronic chip, for example, the intelligent household appliance equipment can realize the remote control and management of a user on the intelligent household appliance equipment by connecting the intelligent household appliance equipment with the electronic equipment.
2) Terminal equipment indicates the electronic equipment who has wireless connection function, and terminal equipment can carry out communication connection through connecting the internet with intelligent household electrical appliances as above, also can directly carry out communication connection through modes such as bluetooth, wifi with intelligent household electrical appliances as above. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built in a floating car, or any combination thereof. The mobile device may include, for example, a cell phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or the like, or any combination thereof, wherein the wearable device includes, for example: smart watches, smart bracelets, pedometers, and the like.
3) "plurality" means two or more, and other terms are analogous. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
4) "correspond" may refer to an association or binding relationship, and a corresponds to B refers to an association or binding relationship between a and B.
The following explains an application scenario of the embodiment of the present invention:
fig. 1 is an application scenario diagram of a laundry detection method for a washing machine according to an embodiment of the present invention, as shown in fig. 1, in the application scenario, after a user puts laundry into an intelligent washing machine, the user selects and starts an "automatic washing" function of the intelligent washing machine to perform a washing operation. After receiving a starting instruction sent by a user through the face of the washing machine or the terminal device, the intelligent washing machine can detect clothes and match the optimal washing program to carry out washing operation according to the detection result.
In the related art, in order to improve the washing quality of the clothes while realizing the full-automatic washing operation, the intelligent washing machine needs to detect the clothes and distinguish different types and colors of clothes so as to match the optimal washing program. However, when the number of laundry loaded into the washing machine is large, different laundry may be blocked, and it is difficult to accurately identify all the laundry by capturing images of the laundry through a camera disposed outside the drum. Therefore, the conventional method for detecting the clothes in the tub by image recognition can only realize full-automatic washing operation matched with the clothes detection and washing program of one or two pieces of clothes to be washed.
Therefore, for the reasons mentioned above, after the intelligent washing machine in the prior art detects the clothes through the image recognition technology, the intelligent washing machine usually configures the washing parameters such as the amount of water, the amount of detergent, and the washing duration required for washing the clothes according to the detection result, and determines the corresponding washing program according to such washing parameters. Since such laundry parameters do not require accurate determination of information on the type, color, and the like of each piece of clothes, they can be determined only by recognizing the general type, volume, and number of the clothes. However, for more accurate washing procedures, such as a "sweater washing" procedure for washing sweater exclusively, and an "underwear washing" procedure for washing underwear exclusively, more accurate detection of the clothes is required. For example, in one particular exemplary scenario, a user puts into laundry in a washing machine, inadvertently mixes a piece of sweater, and must wash using a "sweater washing" program because the sweater cannot use a conventional washing program, or otherwise causes the sweater to be damaged. Under the circumstance, in the prior art, the method for detecting the clothes through the image recognition technology cannot accurately recognize the type of each piece of clothes, so that the washing machine cannot be guaranteed to be matched with a correct washing program of 'sweater washing', and the sweater mixed in the clothes to be washed is damaged in the washing process. Therefore, a more accurate clothes detection method is needed at present, which can accurately detect a plurality of clothes to be washed, so as to realize accurate matching of special washing procedures such as "sweater washing" and "underwear washing", and improve the washing effect of the clothes.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a laundry detection method for a washing machine according to an embodiment of the present invention, which is applied to an intelligent washing machine, and as shown in fig. 2, the laundry detection method for a washing machine according to the embodiment includes the following steps:
step S101, image acquisition is carried out on clothes to be washed in an inner drum of the washing machine, and first image information is obtained.
Illustratively, taking a drum washing machine as an example, an intelligent washing machine is provided with a drum for containing and washing laundry, i.e. a washing machine inner drum, and a controller of the intelligent washing machine can control the washing machine inner drum to rotate, so as to realize the operation processes of washing, dewatering and the like on the laundry in the washing machine inner drum. In a possible implementation manner, an image acquisition unit, such as a camera, is arranged in the intelligent washing machine, and the camera faces the inner side of the inner drum of the washing machine so as to acquire an image of clothes to be washed in the inner drum of the washing machine.
Specifically, the timing of image acquisition of the laundry in the inner drum of the washing machine may be that the intelligent washing machine receives an instruction, which is input by a user and instructs the intelligent washing machine to perform a washing operation, before the washing operation is performed, or before the intelligent washing machine performs the washing operation according to a preset washing plan, which is not specifically limited herein. The method comprises the steps of carrying out image acquisition on the clothes to be washed in the inner drum of the washing machine, and using obtained first image information to represent the characteristics of the clothes to be washed in the inner drum of the washing machine, such as pictures or videos. Optionally, the number of times of image acquisition of the intelligent washing machine on the laundry in the inner drum of the washing machine may be one time or multiple times.
And S102, controlling the inner drum of the washing machine to rotate according to the first image information so as to adjust the position of the clothes to be washed in the inner drum of the washing machine.
Further, the first image information may be used to express the appearance feature and the position feature of the laundry. Taking the first image information as an example of a shot picture of the laundry in the tub, by performing image recognition on the first image information, it can be determined whether occlusion exists between the laundry in the laundry, and if an occlusion state exists between the laundry in the laundry, the inner tub of the washing machine is controlled to rotate, so that positions of the laundry are changed. In one possible implementation, the shielding state between the clothes may refer to a position where a certain clothes cannot be located. For example, according to the washing parameters input by the user, the total number of the clothes to be washed can be determined to be 5, but after image recognition is carried out through the collected first image information, only 4 pieces of clothes are located, and the clothes are determined to be in a shielding state. In another possible implementation, the blocking state between the clothes refers to the position where the clothes can be located, but the type of the clothes cannot be identified. The above two shielding state implementation manners may be used alone or together as a condition for determining whether the clothes are in the shielding state, and are not described herein again.
And step S103, carrying out image acquisition on the clothes to be washed in the inner drum of the rotating washing machine to obtain second image information, and carrying out clothes detection according to the second image information.
Fig. 3 is a schematic diagram of a process of collecting an image of laundry according to an embodiment of the present invention, and referring to fig. 3, after determining that the laundry is in a blocking state, controlling an inner drum of a washing machine to rotate so as to change positions of the laundry, and while or after the inner drum of the washing machine rotates, collecting an image of the laundry in the inner drum of the washing machine again to obtain second image information, where the second image information is, for example, a picture collected by a camera in the inner drum of the washing machine; determining whether the clothes are still in the shielding state, if the clothes are not in the shielding state, directly determining the type of the clothes according to the second image information, and completing the detection of the clothes; if the clothes are in a shielding state, continuously controlling the inner drum of the washing machine to rotate, and obtaining second image information; in the continuous rotation process, the appearance characteristics of new clothes are provided in the second image information acquired every time, the appearance characteristics of the clothes are extracted and fused through the continuous acquisition of the second image information, and the type information of all the clothes to be washed is gradually identified, namely, the clothes are in a non-shielding state. It should be noted that the non-shielding state referred to herein does not mean that the clothes in the laundry are completely separated in physical space, but means that the clothes are in a recognizable state by collecting one or more pieces of second image information and utilizing superposition of appearance features of the clothes at various angles, and finally, accurate detection of the clothes in the laundry is achieved.
In the embodiment, first image information is obtained by carrying out image acquisition on clothes to be washed in an inner barrel of the washing machine; controlling the inner drum of the washing machine to rotate according to the first image information so as to adjust the position of the clothes to be washed in the inner drum of the washing machine; and acquiring an image of the clothes to be washed in the rotating inner drum of the washing machine to obtain second image information, and detecting the clothes according to the second image information. Before detecting the clothes in the washing machine, the clothes condition in the inner drum of the washing machine is analyzed through the pre-collected first image information, the inner drum of the washing machine is controlled to rotate, the position of the clothes in the washing machine is adjusted, second image information capable of better representing the characteristics of the clothes is obtained, the clothes are detected according to the second image information, the recognition rate of the clothes in the washing machine can be improved, the recognition effect is improved, the safety effect of the washing machine can be better guaranteed, and the washing program can be accurately matched.
Fig. 4 is a flowchart of a laundry detection method of a washing machine according to another embodiment of the present invention, as shown in fig. 4, the laundry detection method of the washing machine according to the present embodiment further details steps S102-S103 on the basis of the laundry detection method of the washing machine according to the embodiment shown in fig. 2, and then the laundry detection method of the washing machine according to the present embodiment includes the following steps:
step S201, image acquisition is carried out on the clothes to be washed in the inner drum of the washing machine, and first image information is obtained.
Step S202, according to the first image information, determining shielding information of the clothes to be washed, wherein the shielding information is used for representing shielding degrees among the clothes to be washed.
Illustratively, the occlusion information is information describing an occlusion state between the clothes, and the occlusion information includes, for example, an occlusion coefficient, and the higher the occlusion coefficient is, the greater the occlusion degree between the clothes is, that is, the clothes to be washed are difficult to identify; correspondingly, the smaller the shielding coefficient, the smaller the shielding degree between the clothes is, i.e. the clothes to be washed is easier to identify. Further, the occlusion coefficient may be determined by the result of image recognition, for example, the occlusion coefficient is smaller when the recognition result confidence of a certain target object in the first image information is higher, and conversely, the occlusion coefficient is larger when the recognition result confidence of a certain target object in the first image information is lower.
And step S203, determining the rotation program of the inner drum of the washing machine according to the shielding information.
And step S204, controlling the rotation of the inner barrel of the washing machine according to the rotation program of the inner barrel of the washing machine.
Specifically, the shielding information is used for representing the shielding degree information among the clothes, and when the shielding degree among the clothes is large, the shielding information corresponds to the situation in a real scene, namely the clothes in the inner drum of the washing machine are interwoven together, and the clothes which are seriously interwoven together cannot be separated by simply controlling the inner drum to rotate by a certain angle, so that the clothes are identified. Therefore, when the shielding degree between the clothes is large, that is, the clothes are seriously interlaced, the inner drum of the washing machine needs to be rotated at a high speed or at a variable speed to separate the interlaced clothes, so that more appearance features of the clothes are exposed, and the recognition speed and the recognition accuracy of the clothes are improved.
Further, the washing machine drum rotation program is illustratively used to control drum rotation speed, and/or drum rotation angle. Specifically, according to the shielding information, the intelligent washing machine determines a corresponding washing machine inner barrel rotation program, so that the washing machine inner barrel rotates at different angles at different rotation speeds. In a more specific embodiment, the shielding coefficient in the shielding information has a preset mapping relation with the washing machine drum rotation program. For example, when the shielding coefficient is 0.2, determining a washing machine inner barrel rotation program A according to a preset mapping table, and controlling the washing machine inner barrel to rotate 90 degrees at the speed of 0.3 r/s; and when the shielding coefficient is 0.8, determining a washing machine inner barrel rotation program B according to a preset mapping table, controlling the washing machine inner barrel to rotate for 90 degrees at the speed of 3 revolutions per second, then stopping for 0.5 second, and repeating the process for 5 times. The mapping relation between the different washing machine inner cylinder rotation programs and the shielding information is related to different inner cylinder structures, the mapping relation can be preset when the intelligent washing machine leaves a factory, and can also be set by a user according to needs, and the mapping relation is not described in detail here.
In the embodiment, the corresponding rotation program of the inner drum of the washing machine is determined according to the shielding information, and the inner drum of the washing machine is controlled to rotate at the inner drum rotation angle and the inner drum rotation speed which are matched, so that the appearance characteristics of the clothes can be better exposed by the rotation of the inner drum, and the clothes detection efficiency and the clothes detection accuracy are improved.
In one possible implementation, determining a washing machine drum rotation program further includes:
acquiring weight information of clothes to be washed in an inner drum of the washing machine; and determining the rotation program of the inner drum of the washing machine according to the shielding information of the clothes to be washed and the weight information of the clothes to be washed.
Illustratively, the purpose of the rotation of the inner drum of the washing machine is to change the position of the clothes in the inner drum of the washing machine, so as to better collect image information and identify the type of the clothes, and when the number of the clothes in the inner drum is large, the shielding situation between the clothes is more complicated, so that, in order to better identify the type of each clothes, the quantity of the clothes is judged by collecting the weight information of the clothes to be washed, and when the weight of the clothes to be washed is large, the inner drum of the washing machine can be rotated fully by using a larger rotating speed and a larger rotating angle, so that the position between the clothes can be changed obviously, so that the appearance characteristics of the clothes are more exposed, and the collected second image information can include more appearance characteristics of the clothes, thereby improving the speed and the accuracy of clothes identification.
In the embodiment, by acquiring the weight information of the clothes to be washed and determining the rotation program of the inner drum of the washing machine according to the shielding information of the clothes to be washed and the weight information of the clothes to be washed, the rotation program of the inner drum of the washing machine can be matched with the proper weight of the clothes, so that the inner drum of the washing machine can rotate more fully, the number of the effective appearance characteristics of the clothes collected in the second image information is increased, the times of collecting the second image information is reduced, and the effect of improving the clothes detection efficiency is realized.
Step S205, collecting an image of the laundry in the inner drum of the rotating washing machine to obtain second image information, performing image recognition on the second image information, and determining a color and/or a type of the laundry corresponding to each laundry in the laundry.
In particular, in the rotating inner drum of the washing machine, the position of the clothes to be washed is changed, so that the appearance characteristics of the clothes which cannot be obtained when the clothes are in a shielding state can be obtained through the collected second image information. Further, by performing image recognition using the second image information, recognition of the laundry, specifically, including recognition of the color of the laundry and the type of the laundry, may be achieved.
Step S206, according to the corresponding clothes color and/or clothes type of each clothes in the clothes to be washed, starting the corresponding washing program.
In particular, the intelligent washing machine is provided with special washing programs designed for specific clothes types and clothes colors. For example, "sweater washing" procedures, which are specialized for washing sweaters, preventing deformation and shrinkage of the sweater; as another example, a "colored laundry washing" program that specializes in users washing laundry that is prone to color fading. The program of 'sweater washing' needs to be called after the type of clothes is determined; the program of "washing colored clothes" needs to be called after the color of the clothes is determined.
In the embodiment, the clothes are identified, the clothes type and the clothes color are determined, and the accurate matching of the special washing program can be realized. Since the special laundry program is usually specific to a specific laundry scene and a specific type of clothes, such as the "sweater washing" program and the "colored laundry washing" program in the above examples, if the type of clothes and the color of clothes of each piece of clothes to be washed cannot be accurately detected, the clothes are detected by the conventional image detection technology in the prior art, if one piece of sweater is missed and the "sweater washing" program is not used, the damage to the piece of sweater is caused, and if one piece of colored clothes is missed and the "colored laundry washing" program is not used, all pieces of clothes are dyed. Therefore, in the embodiment, the technical characteristic that the first image information controls the rotation of the inner drum of the washing machine is matched with the acquisition of the second image information to perform image recognition, so that the types and colors of the clothes are obtained, and a special washing program is determined to perform clothes washing according to the image recognition, so that the real full-automatic washing operation is realized, the problem that a user needs to perform a process of screening the clothes to be washed manually in the front due to the fact that each piece of clothes cannot be detected accurately is avoided, and the washing efficiency and the washing effect are improved.
And step S207, performing image recognition on the second image information, and determining whether living creatures exist in the inner drum of the washing machine.
Specifically, as a common household appliance, in a household with pets and infants, if living organisms such as pets or infants enter an inner barrel of the washing machine, the washing machine starts water injection and washing operations, and then the living organisms are greatly damaged, which causes safety accidents. Therefore, before the washing machine executes the washing program to perform operation, the intelligent washing machine performs image recognition according to the second image information, and detection of living organisms hidden in the clothes to be washed can be achieved. In some special scenes, for example, in an indoor environment with low air temperature, living creatures such as pets and the like enter clothes in an inner drum of the washing machine for the purpose of warming and rest, so that in the scene, the conventional clothes detection method based on image detection is static to acquire images, and the living creatures hidden under the clothes are difficult to find, so that the detection omission of the living creatures is caused. In the embodiment, since the inner drum of the washing machine is rotated by the first image information in the above steps, the living creatures hidden in the clothes can be warned to move out of the clothes, so that the living creatures hidden in the clothes can be better found, and the detection effect of the living creatures is improved.
