The present disclosure generally relates to the technical field of computers, and more particularly, to a foreign matter recognition method and device.
Washing devices such as laundry washers have become a main tool for garment washing for most people. However, some careless users may forget to check or miss checking about whether there are foreign matters such as keys, coins and mobile phones in pockets when garments are washed. Those foreign matters may damage garments inside the washing devices and may even damage the washing devices when the washing devices are used to wash the garments.
The present disclosure provides a method, a device and a non-transitory computer-readable medium for recognizing a foreign matter.
According to a first aspect of the present disclosure, there is provided a foreign matter recognition method, which may include: detecting whether a garment to be washed that is placed in a washing device meets a foreign matter recognition condition; in the case that the garment to be washed meets the foreign matter recognition condition, recognizing that a foreign matter exists in the garment to be washed; and indicating existence of the foreign matter.
According to a second aspect of the present disclosure, there is provided a foreign matter recognition device, which may include: a processor; and a memory arranged to store an instruction executable for the processor, where the processor may be arranged to: detect whether a garment to be washed that is placed in a washing device meets a foreign matter recognition condition; in the case that the garment to be washed meets the foreign matter recognition condition, recognize that a foreign matter exists in the garment to be washed; and indicate existence of the foreign matter.
According to a third aspect of the present disclosure, there is provided a non-transitory computer-readable storage medium having stored thereon instructions that, when executed by a processor, cause the processor to implement detecting whether a garment to be washed that is placed in a washing device meets a foreign matter recognition condition; in the case that the garment to be washed meets the foreign matter recognition condition, recognizing that a foreign matter exists in the garment to be washed; and indicating existence of the foreign matter.

These terms are only used to distinguish one category of information from another. For example, without departing from the scope of the present disclosure, first information may be termed as second information; and similarly, second information may also be termed as first information. As used herein, the term “if” may be understood to mean “when” or “upon” or “in response to” depending on the context.
In Step S11, it is detected whether a garment to be washed that is placed in the washing device meets a foreign matter recognition condition.
For example, when a user places the garment to be washed in the washing device (for example, the smart washing machine) for washing, the washing device may detect the garment to be washed. In such a manner, whether the garment to be washed meets the foreign matter recognition condition may be determined or judged.
In Step S111, the garment to be washed is scanned to acquire a scanned image of the garment to be washed.
In a possible implementation mode, the garment to be washed may be scanned to acquire the scanned image of the garment to be washed through X rays.
For example, the washing device may include an X ray scanning function, and may perform X ray scanning on the garment to be washed, thereby acquiring the scanned image of the garment to be washed. Those skilled in the art should know that the garment to be washed may be scanned in multiple manners, for example, an ultrasonic wave, as long as the scanned image of the garment to be washed may be acquired, which will not be limited in the present disclosure.
In a possible implementation mode, the washing device may scan the garment to be washed through a parallel X ray scanning function, herein the parallel X ray scanning function may refer to that the garment to be washed may be structurally subjected to X ray scanning and then enter the washing device.
For example, the washing device may include an inlet, herein the inlet may be arranged for the garment to be washed to enter the washing device. The washing device may further include a parallel X ray scanning part, and before entering the washing device, the garment to be washed of the user may pass through the parallel X ray scanning part at first (for example, the parallel X ray scanning part is arranged in front of the inlet), so that scanning of the garment to be washed by the washing device is implemented. For example, when being placed in the washing device by the user, the garment to be washed may pass through the parallel X ray scanning part in front of the inlet and enter the washing device (for example, a drum of the smart washing machine) from the inlet.
In such a manner, the washing device may scan the garment to be washed through the parallel X ray scanning part and acquire the scanned image of the garment to be washed.
In a possible implementation mode, the washing device may scan the garment to be washed through an embedded X ray scanning function, herein the embedded X ray scanning function may refer to that an X ray scanning part is arranged on a machine body of the washing device.
For example, the X ray scanning part may be arranged on a housing of the washing device. When the user places the garment to be washed in the washing device, the washing device may scan the garment to be washed through the X ray scanning part and acquire the scanned image of the garment to be washed.
In such a manner, the washing device may scan the garment to be washed directly through the embedded X ray scanning function, thereby ensuring that the washing device is simple in structure and small in size.
Those skilled in the art should know that multiple realization manners may be adopted for the X ray scanning function, and a structure and position of the X ray scanning part and a manner in which the garment to be washed enters the washing device may also be set according to a requirement, as long as the garment to be washed may be scanned and the scanned image of the garment to be washed may be acquired. There are no limits made in the present disclosure.
In Step S112, an image area in the scanned image that has a color depth larger than or equal to a depth threshold value is determined.
In Step S113, in the case that the image area has an area value larger than or equal to an area threshold value, it is judged that the garment to be washed meets the foreign matter recognition condition.
For example, the washing device may recognize a color characteristic of the scanned image 3 and determine the image area 31 of which the color depth is larger than or equal to the depth threshold value (for example, 50%) in the scanned image 3, herein a color depth of the scanned image 3 is 0-100% from all white to all black. Those skilled in the art should know that the image area in the scanned image that has a color depth larger than or equal to the depth threshold value may be determined through the related technology, for example, an image recognition technology, which will not be limited in the present disclosure. In addition, the depth threshold value may be set by a system as a default, and may also be selected and set by the user according to a personal requirement. A specific setting manner and range of the depth threshold value will not be limited in the present disclosure.
In a possible implementation mode, when the image area has an area value larger than or equal to an area threshold value, it may be judged that the garment to be washed meets the foreign matter recognition condition. For example, as shown in
In a possible implementation mode, the characteristic of the scanned image may further be recognized and analyzed, thereby judging whether the garment to be washed meets the foreign matter recognition condition. For example, foreign matter recognition may be performed according to features of scanned images obtained by scanning different materials and components (for example, the scanned images obtained by scanning different materials and components are different in color) as characteristics, and foreign matter recognition may also be performed according to features of scanned images corresponding to structures and shapes of foreign matters as characteristics. In such a manner, whether the garment to be washed meets the foreign matter recognition condition may be accurately judged on the basis of the characteristic of the scanned image. Those skilled in the art should know that foreign matter recognition condition judgment may be performed according to one characteristic or multiple characteristics of the scanned image, as long as whether the garment to be washed meets the foreign matter recognition condition may be judged on the basis of the characteristic of the scanned image. There are no limits made in the present disclosure.
In Step S114, the garment to be washed is detected through a metal sensing part.
For example, the garment to be washed may be detected through the metal sensing part capable of sensing a metal. In such a manner, whether a metal object exists in the garment to be washed may be detected.
For example, the washing device 5 may include an inlet 51, and the inlet 51 is arranged for the user to place the garment to be washed. The metal sensing part 52 (for example, the metal detection loop capable of sensing a metal) may be arranged at the inlet 51. In such a manner, when the user places the garment to be washed in the washing device, the garment to be washed may be detected through the metal sensing part. Those skilled in the art should know that a structure, type and position of the metal sensing part may be set according to a requirement, as long as the garment to be washed may be detected, which will not be limited in the present disclosure.
In Step S115, in the case that a metal object is detected to exist in the garment to be washed, it is judged that the garment to be washed meets the foreign matter recognition condition.
For example, when the metal object (for example, a key, a mobile phone and a coin) exists in the garment to be washed that is placed in the washing device 5 by the user, the metal sensing part 52 of the washing device 5 may detect that the metal object exists in the garment to be washed, thereby judging that the garment to be washed meets the foreign matter recognition condition. In such a manner, it may be detected whether the metal object exists in the garment to be washed that is placed in the washing device, and when the metal object is detected to exist, it is judged that the garment to be washed meets the foreign matter recognition condition.
Those skilled in the art should know that whether the garment to be washed that is placed in the washing device meets the foreign matter recognition condition may be detected in multiple manners, not limited to the abovementioned examples. Detection manners of the washing device may include multiple forms. For example, whether the garment to be washed meets the foreign matter recognition condition may be judged only by scanning the garment to be washed and analyzing the scanned image or whether the garment to be washed meets the foreign matter recognition condition may be detected only through the metal sensing part, and whether the garment to be washed meets the foreign matter recognition condition may also be detected through the metal sensing part by scanning the garment to be washed and analyzing the scanned image, as long as whether the garment to be washed that is placed in the washing device meets the foreign matter recognition condition may be detected. There are no limits made in the present disclosure.
As shown in
For example, when the washing device detects that the garment to be washed that is placed by the user meets the foreign matter recognition condition, the washing device may recognize that the foreign matter exists in the garment to be washed. Those skilled in the art should know that the foreign matter may be recognized to exist in the garment to be washed through the related technology, as long as it may be recognized that the foreign matter exists in the garment to be washed in the case that the garment to be washed meets the foreign matter recognition condition. A specific recognition manner will not be limited in the present disclosure.
In Step S13, a prompt indicating existence of the foreign matter is given.
For example, in the case that the foreign matter is recognized to exist in the garment to be washed, the washing device may suspend work and gives the prompt (for example, a voice prompt) corresponding to existence of the foreign matter to the user to prompt the user for timely checking and handling.
In Step S131, a prompting sound is produced through a sound producing part of the washing device.
For example, in the case that the garment to be washed meets the foreign matter recognition condition, it may be recognized that the foreign matter exists in the garment to be washed. The prompting sound may be produced through the sound producing part of the washing device. For example, in the case that the foreign matter exists in the garment to be washed that is placed in the smart washing machine by the user, a prompting voice may be produced through own sound producing part (for example, a speaker) of the smart washing machine. For example, “a foreign matter is detected in the garment, please handle it” may be produced. Beeps may be produced for warning prompting through the sound producing part of the smart washing machine. In such a manner, the user may be clearly prompted to check whether the foreign matter exists in the garment to be washed through a voice.
In Step S132, a prompting content is displayed on a display part of the washing device.
For example, in the case that the garment to be washed meets the foreign matter recognition condition, it may be recognized that the foreign matter exists in the garment to be washed. The display part of the washing device may be adopted for display. For example, in the case that the foreign matter exists in the garment to be washed that is placed in the smart washing machine by the user, a corresponding prompting text or abnormity list may be displayed on the display part (for example, a display panel) of the smart washing machine.
In Step S133, prompting information is sent to terminal equipment associated with the washing device for the terminal equipment to give a corresponding prompt.
For example, in the case that the garment to be washed meets the foreign matter recognition condition, it may be recognized that the foreign matter exists in the garment to be washed. The prompting information may be sent to the terminal equipment (for example, a smart mobile phone and a tablet) associated with the washing device for the terminal equipment to give the corresponding prompt (for example, a prompting manner of voice, text, vibration and the like). For example, the smart washing machine may be associated with a smart mobile phone of the user in a manner of Bluetooth (BT), Wireless Fidelity (WIFI), a network signal or the like. In the case that the foreign matter is recognized to exist in the garment to be washed, the washing machine may send the prompting information (the foreign matter exists in the garment to be washed) to the associated smart mobile phone, and the smart mobile phone gives the corresponding prompt. For example, the smart mobile phone may produce a prompting voice and the like.
In such a manner, a foreign matter prompt may be given through the terminal equipment of the user, and foreign matter prompting is remotely and intelligently implemented.
Those skilled in the art should know that the washing device may give the prompt indicating existence of the foreign matter in multiple manners. The prompt may be given in only one manner, for example, the prompting sound is produced through the sound producing part of the washing device, and the prompt may also be given in multiple manners, for example, the prompting sound is produced through the sound producing part of the washing device, and meanwhile, the associated terminal equipment synchronously gives the prompt, as long as the prompt indicating existence of the foreign matter may be given in the case that the foreign matter is recognized to exist in the garment to be washed. There are no limits made in the present disclosure.
According to the example of the present disclosure, it is detected whether the garment to be washed that is placed in the washing device meets the foreign matter recognition condition, and in the case that the foreign matter recognition condition is met, it is recognized that the foreign matter exists in the garment to be washed, and the prompt indicating existence of the foreign matter is given, so that the user is prompted to timely clean the foreign matter in the garment to be washed to avoid damage brought by the foreign matter.
An application example according to the example of the present disclosure will be given below for conveniently understanding the flow of the foreign matter recognition method in combination with an exemplary application scenario that “a user places a garment to be washed in a washing machine for washing”. Those skilled in the art should know that the below application example is only intended to make the example of the present disclosure conveniently understood, and should not be considered as a limit to the example of the present disclosure.
In the application example, the washing machine has both an X ray scanning function (for example, including a parallel or embedded X ray scanning part) and a metal sensing part (for example, a magnetic sensing coil or a metal detection loop is arranged at an inlet of the washing machine). In the application example, when the garment to be washed passes through the inlet of the washing machine, the washing machine may detect whether the garment to be washed meets a foreign matter recognition condition (Step S701). For example, the X ray scanning part may scan the garment to be washed and acquire a scanned image of the garment to be washed.
In the application example, an image recognition function of the washing machine may recognize an image area in the scanned image that has a color depth larger than or equal to a depth threshold value, and when the image area being larger than or equal to an area threshold value, it may be judged that the garment to be washed meets the foreign matter recognition condition. In the application example, the metal sensing part of the washing machine may also detect the garment to be washed, and in the case that a metal object exists in the garment to be washed, it is judged that that garment to be washed meets the foreign matter recognition condition (Step S702).
In the application example, in the case that the garment to be washed meets the foreign matter recognition condition, it may be recognized that a foreign matter exists in the garment to be washed (Step S703). In the application example, the washing machine suspends work (Step S704). In the application example, a prompting voice “a foreign matter is detected in the garment to be washed, please handle it” is produced through a speaker of the washing machine (Step S705), meanwhile, a prompting content, for example, the foreign matter exists in the garment, is displayed on a display panel of the washing machine (Step S706), and a prompt, for example, voice and vibration prompts, may further be given through a smart mobile phone, associated with the washing machine, of the user (Step S707).
In the application example, after acquiring the scanned image of the garment to be washed through the X ray scanning part, the washing machine recognizes and analyzes a characteristic of the scanned image, and in the case that the image area is smaller than the area threshold value, when the metal sensing part of the washing machine detects no metal object existing in the garment to be washed, may judge that the garment to be washed does not meet the foreign matter recognition condition (Step S708). In the application example, it may be recognized that no foreign matter exists in the garment to be washed (Step S709). In the application example, the washing machine woks normally (Step S710).
According to the example of the present disclosure, it is detected whether the garment to be washed that is placed in the washing device meets the foreign matter recognition condition, and in the case that the foreign matter recognition condition is met, it is recognized that the foreign matter exists in the garment to be washed, and the prompt indicating existence of the foreign matter is given, so that the user is prompted to timely clean the foreign matter in the garment to be washed to avoid damage brought by the foreign matter.
