Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1a is a flowchart illustrating a gesture control method according to an exemplary embodiment, and as shown in fig. 1a, the gesture control method includes the following steps 101 to 103:
in step 101, a first picture is obtained, the first picture comprising a first gesture image of a user.
In step 102, characteristic parameters of the first gesture image are acquired, and the characteristic parameters include a finger type and/or a finger number corresponding to the first gesture image.
In step 103, a target control object to be controlled is determined according to the characteristic parameters of the first gesture image, wherein the target control object comprises a target device, a target operation object or a target function item.
It should be noted that, a device may include at least one operation object; one operation object may correspond to at least one function item. For example, if the device is a range hood, the range hood may include operation objects of a left air opening and a right air opening; the corresponding function items of the left air opening and the right air opening can be wind power and wind direction. Or, if the device is a cooker, the cooker may include an operation object that is a left cooker and a right cooker; the function items corresponding to the left cooking range and the right cooking range can be opening, fire and extinguishing.
For example, the gesture control method may be applied to a central control device in a kitchen, where the central control device is connected to a camera and can control a plurality of devices, and at this time, the plurality of devices may be intelligent kitchenware. The central control device can acquire a picture shot by the camera in real time and then determine whether the picture comprises a gesture image of the user. If yes, determining the picture as a first picture, wherein the gesture image included in the picture is the first gesture image; if not, discarding the picture and continuing monitoring.
After the first picture is acquired, the central control device may determine the characteristic parameters of the first gesture image through image recognition, that is, determine the type and/or the number of fingers that the first gesture image indicates that the user extends, and then acquire the target control object according to the type and/or the number of fingers. Specifically, the central control device may determine the target device to be controlled from the multiple devices controlled by the central control device according to the characteristic parameter of the first gesture image. Or after the target device to be controlled is determined, the target operation object to be controlled is determined from at least one operation object included in the target device according to the characteristic parameters of the first gesture image, and at this time, the device currently used by the user may be determined as the target device. Or after the target operation object to be controlled is determined, according to the characteristic parameter of the first gesture image, the target function item to be controlled is determined from at least one function item corresponding to the target operation object, and at this time, the operation object included in the device currently used by the user may be determined as the target operation object.
Wherein the finger type may be a one-finger type, such as thumb, index finger, middle finger, ring finger, and pinky finger; a combination of multiple fingers, such as a combination of a thumb and an index finger, a combination of an index finger, a middle finger and a ring finger, a combination of an index finger, a middle finger, a ring finger and a little finger, etc., may also be used, which is not limited in this disclosure.
Optionally, the central control device prestores a corresponding relationship between the characteristic parameter and the control object, and after the characteristic parameter of the first gesture image is obtained, the corresponding relationship may be referred to according to the characteristic parameter of the first gesture image, and the control object corresponding to the characteristic parameter of the first gesture image is obtained as the target control object.
Taking the characteristic parameter as a finger type and the target control object as a target device as an example, assuming that the device corresponding to the index finger is recorded in the corresponding relationship between the characteristic parameter and the control object as an electric cooker, the device corresponding to the middle finger is a range hood, and the device corresponding to the ring finger is a cooker, the central control device recognizes that the corresponding finger type of the first gesture image is the index finger, that is, when the user currently extends the index finger, the user indicates that the user needs to control the electric cooker through a gesture, and at this time, the central control device can determine the electric cooker as the target control object; or the central control device recognizes that the corresponding finger type of the first gesture image is the ring finger, that is, when the user stretches out the ring finger currently, the user indicates that the user needs to control the cooker through the gesture, and at this time, the central control device can determine the cooker as the target control object. After the target device is acquired, the central control device may send selected information to the target device, and the target device may display the reminding information after receiving the selected information, so that after the reminding information is referred to by a user, a target operation object is determined again from at least one operation object included in the target device through a gesture, and a target function item is determined from at least one function item corresponding to the target operation object.
Taking the characteristic parameter as a finger type and the target control object as a target operation object as an example, assuming that the corresponding relation between the characteristic parameter and the control object records that the combination of the index finger and the middle finger corresponds to the left air port of the range hood, the combination of the ring finger and the middle finger corresponds to the right air port of the range hood, the combination of the ring finger and the index finger corresponds to the left cooking range of the kitchen range, and the combination of the ring finger and the little finger corresponds to the right cooking range of the kitchen range. When the central control device recognizes that the corresponding finger type of the first gesture image is the combination of the index finger and the middle finger, that is, when the user stretches out the index finger and the middle finger at the same time, the user indicates that the user needs to control the left air port of the range hood through a gesture, and at this time, the central control device can determine the left air port of the range hood as a target control object; or the central control device recognizes that the corresponding finger type of the first gesture image is a combination of the ring finger and the little finger, that is, the user stretches out the ring finger and the little finger at the same time, which indicates that the user needs to control the right cooking range of the cooking range through the gesture, and at this time, the central control device can determine the right cooking range of the cooking range as the target control object. After the target operation object is acquired, the central control device may send selected information to the target device corresponding to the target operation object, and the target device may display the reminding information after receiving the selected information, so that the user determines the target function item from the at least one function item corresponding to the target operation object through a gesture again after looking up the reminding information.
Taking the characteristic parameter as the number of fingers and the target control object as the target device as an example, assuming that the corresponding relationship between the characteristic parameter and the control object records that the device corresponding to one finger is an electric cooker, the devices corresponding to two fingers are a range hood, and the devices corresponding to three fingers are kitchen ranges, the central control device recognizes that the number of the corresponding fingers of the first gesture image is two, that is, when the user extends two fingers currently, the user needs to control the range hood through a gesture, and at this time, the central control device can determine the range hood as the target control object.
For example, the gesture control method can also be applied to a target device, which can be an intelligent kitchen ware, is provided with a camera and comprises at least one operation object. The target device can acquire a picture shot by the camera in real time and then determine whether the picture comprises a gesture image of the user. If yes, determining the picture as a first picture, wherein the gesture image included in the picture is the first gesture image; if not, discarding the picture and continuing monitoring.
After the first picture is acquired, the target device may determine the characteristic parameter of the first gesture image through image recognition, that is, determine the type and/or number of fingers that the first gesture image indicates that the user extends, and then acquire the target control object according to the type and/or number of fingers. Specifically, the target device may determine a target operation object to be controlled from at least one operation object included in the first gesture image according to the characteristic parameter of the first gesture image. Or after the target operation object to be controlled is determined, according to the characteristic parameter of the first gesture image, the target function item to be controlled is determined from at least one function item corresponding to the target operation object, and at this time, the operation object included in the device currently used by the user may be determined as the target operation object.
The finger type may be a single finger type, or a combination of multiple fingers, which is not limited in this disclosure.
Optionally, the target device prestores a corresponding relationship between the feature parameter and the control object, and after the feature parameter of the first gesture image is obtained, the corresponding relationship may be referred according to the feature parameter of the first gesture image, and the control object corresponding to the feature parameter of the first gesture image is obtained as the target control object.
Taking the characteristic parameter as a finger type, the target device as a range hood, and the target control object as a target operation object as examples, it is assumed that the correspondence between the characteristic parameter and the control object describes that the operation object corresponding to the index finger is a left air opening, and the operation object corresponding to the middle finger is a right air opening. When the target device recognizes that the corresponding finger type of the first gesture image is the index finger, that is, when the user stretches out the index finger currently, it indicates that the target device needs to control the left air port of the currently used range hood through a gesture, and at this time, the range hood can determine the left air port as a target control object; or, when the target device recognizes that the corresponding finger type of the first gesture image is the middle finger, that is, when the user currently stretches out the middle finger, it indicates that the user needs to control the right air opening of the range hood currently in use through a gesture, and at this time, the range hood may determine the right air opening as the target control object. After the target operation object is determined, the target device may display the reminding information, so that after the reminding information is referred to by the user, the target function item is determined again from the at least one function item corresponding to the target operation object through the gesture.
Taking the characteristic parameter as a finger type, the target device as a range hood, and the target control object as a target operation object as examples, it is assumed that the correspondence between the characteristic parameter and the control object describes the wind power of the left air opening of the range hood corresponding to the combination of the index finger and the middle finger, the direction of the left air opening of the range hood corresponding to the combination of the ring finger and the middle finger, the wind power of the right air opening of the range hood corresponding to the combination of the ring finger and the index finger, and the direction of the right air opening of the range hood corresponding to the combination of the ring finger and the little finger. When the smoke exhaust ventilator recognizes that the corresponding finger type of the first gesture image is the combination of the index finger and the middle finger, namely when the user stretches out the index finger and the middle finger at the same time, the smoke exhaust ventilator indicates that the user needs to control the wind power of the left air port through gestures, and at the moment, the smoke exhaust ventilator can specify the wind power of the left air port as a target control object; or the target device recognizes that the corresponding finger type of the first gesture image is a combination of the ring finger and the little finger, that is, the user stretches out the ring finger and the little finger at the same time, which indicates that the direction of the right air port of the range hood needs to be controlled through the gesture, and at this time, the target device can determine the direction of the right air port of the range hood as a target control object.
Taking the characteristic parameter as the number of fingers, the target device as a cooker, and the target control object as a target operation object as examples, assuming that the corresponding relationship between the characteristic parameter and the control object records that the device corresponding to one finger is a left cooking range, and the device corresponding to two fingers is a right cooking range, the cooker recognizes that the number of the corresponding fingers of the first gesture image is two, that is, when the user extends two fingers currently, the cooker needs to control the right cooking range of the cooker through gestures, and at this time, the cooker can determine the right cooking range as the target control object.
According to the technical scheme, the user can select the target control object to be controlled through gestures in the cooking process, and then the target control object is adjusted, so that the friendliness of the intelligent device and the convenience of user operation are improved, and the user experience is better.
In one embodiment, the target control object is a target device. As shown in fig. 1b, the method further comprises steps 104 and 105:
in step 104, a pointing region of a first gesture image included in the first picture is obtained.
In step 105, a target operation object to be controlled is determined from a plurality of operation objects included in the target device according to the pointing region of the first gesture image.
For example, the pointing region of the first gesture image may be a location of the first gesture image on the first picture. Specifically, the target device stores a corresponding relationship between the pointing region and the operation object in advance, and different pointing regions correspond to different operation objects. After the pointing region is obtained, the target operation object can be determined according to the corresponding relation between the pointing region and the operation object.
Taking the target device as the range hood as an example, the corresponding relation between the pointing region and the operation object records that the operation object corresponding to the left region is the left air inlet; the operation object corresponding to the right area is a right air opening. At this time, the range hood may determine whether the first gesture image is located on the left or right side of the first picture after the first picture is acquired. If the first gesture image is located on the left side, the indication area of the first gesture image is a left side area, and at this time, the left air opening can be determined as a target operation object; if the position is on the right side, the indication area of the first gesture image is the right side area, and at this time, the right air opening can be determined as the target operation object.
In practical application, a corresponding relation between the pointing region and the function item of the operation object can be set, and the corresponding relation can record that the function item of the operation object corresponding to the upper left region is the wind power of the left air inlet; the function item of the operation object corresponding to the lower left area is the wind direction of the left wind port; the function item of the operation object corresponding to the upper right area is the wind power of a right air inlet; the function item of the operation object corresponding to the lower right area is the wind direction of the right wind opening. After the range hood acquires the first picture, the function item required to be operated by the user can be determined according to the area of the first picture occupied by the first gesture image, and the specific process can refer to the above embodiment.
In one embodiment, the target control object is a target operation object or a target function item. As shown in fig. 1c, the method further comprises step 106 and step 107:
in step 106, acquiring a pointing region of a first gesture image included in the first picture;
in step 107, a target device to be controlled is determined from the plurality of devices according to the pointing region of the first gesture image.
For example, after acquiring the first image, the central control device may first acquire a pointing region of a first gesture image included in the first image, then determine a target device to be controlled from the multiple devices according to the pointing region, then acquire a characteristic parameter of the first gesture image, and determine a target operation object or a target function item according to the characteristic parameter. Alternatively, the pointing region of the first gesture image may be a positional relationship between the first gesture image and an image of the target device on the first picture. For example, the pointing region of the first gesture image may be above or below it in the first picture.
For example, the central control device first acquires a first picture, the first picture further includes images of a plurality of devices controlled by the central control device in addition to the first gesture image, then acquires an object located below the first gesture image in the first picture, and then determines a device corresponding to the object as a target device, where a pointing region of the first gesture image is below the first picture.
It should be noted that, the user may select the target device and the target operation object in sequence according to the above method until reaching the target function item, and then directly adjust the target function item. For example, the target device may be determined from the plurality of devices through the pointing region of the first gesture image, the target operation object may be acquired from the plurality of operation objects included in the target device through the finger type of the first gesture image, and then the target function item may be determined from the plurality of function items corresponding to the target operation object through the number of fingers of the first gesture image. The user may complete the above determination process through one gesture instruction, or may complete the determination process through multiple gesture instructions, which is not limited in the embodiments of the present disclosure.
In one embodiment, as shown in FIG. 1d, the method includes steps 108-110:
in step 108, after the target function item is determined, a plurality of second pictures are acquired, and each second picture comprises a second gesture image of the user.
In step 109, a gesture motion trajectory is obtained according to the second gesture images included in the plurality of second pictures.
In step 110, the target function item is adjusted according to the gesture motion trajectory.
For example, after the target function item is determined by one gesture operation, the central control device may continuously obtain the pictures acquired by the camera for multiple times, and then determine continuous multiple pictures with gesture images in the multiple pictures as multiple second pictures. And determining a gesture motion track by analyzing the positions of the second gesture images included in the plurality of second pictures, and then adjusting the target function item according to the gesture motion track. Optionally, the central control device stores a corresponding relationship between the gesture motion trajectory and the adjustment operation, for example, a parameter value is adjusted to the right rotation direction; rotating left to adjust the parameter value; or close to the center; opening to the periphery. After the gesture motion track is acquired, the corresponding relation between the gesture motion track and the adjustment operation can be inquired, and how to adjust the target function item is determined.
The gestures of the first gesture image and the second gesture image may be the same or different, and the embodiment of the present disclosure is described by taking the same as the above two gestures, but the present disclosure is not limited thereto.
For example, when the user needs to adjust the air volume of the range hood (at the same time, the air volume of the left and right air ports is adjusted), the user can stretch out the thumb below the range hood. After the first picture is acquired, the central control device can identify an object image in a pointing region (above) of the first gesture image included in the first picture. If the range hood is the device corresponding to the object image, the range hood can be determined as the target device. Then, the central control device can identify the finger type of the first gesture image, and if the finger type of the first gesture image is the thumb, the wind power of an air opening included in the range hood is used as a target function item. After determining the target function item, the central control device may instruct the range hood to display a reminder message. The user may rotate the entire hand of the extended thumb clockwise after reviewing the reminder. In the process, the central control device can continuously acquire a plurality of second pictures, the gesture motion track of the second gesture image can be known to rotate rightwards for the thumb through analysis of the second gesture image included by the plurality of second pictures, the central control device determines that the air volume of the range hood needs to be increased by the user at present by looking up the corresponding relation between the gesture motion track and the adjustment operation, and the air volume of the range hood can be gradually increased along with the rotation of the user. In practical application, the rotation of the user and the air volume increase of the range hood can be performed simultaneously, and the arm can be stopped rotating when the user determines that the air volume is enough, namely the whole gesture operation process is finished. Alternatively, the user may rotate the entire hand of the extended thumb counterclockwise after reviewing the reminder information. In the process, the central control device can continuously acquire a plurality of second pictures, the gesture motion track of the second gesture image can be known to rotate left for the thumb through analysis of the second gesture image included by the plurality of second pictures, the central control device determines that the air volume of the range hood needs to be reduced by the user at present through looking up the corresponding relation between the gesture motion track and the adjustment operation, and the air volume of the range hood can be gradually reduced along with the rotation of the user. In practical application, the air volume reduction of the user rotating arm and the range hood can be carried out simultaneously, the rotating arm can be stopped when the user determines that the air volume is enough, and the whole gesture operation process is finished.
For example, when the user needs to adjust the fire power of the left cooking range, five fingers can be extended above the left cooking range to form a shape for gripping the air.
