[0053] As Figures 1 to 3 shown, an embodiment of the present invention provides an image acquisition device. The image acquisition device is used to acquire the internal image of the inner tub for placing clothes of a washing and drying device. The image acquisition device includes a rotating assembly 1, a fixed assembly 2, a rotational speed detection part, a steering detection part and a main control part. A camera 71 for shooting is arranged on the rotating assembly 1, and the camera 71 is arranged to face the inner cavity of the inner tub. The fixed assembly 2 is used to be installed on the washing and drying device; the rotating assembly 1 is rotatably arranged on the fixed assembly 2. The rotational speed detection part, the steering detection part and the rotating assembly 1 are all connected to the main control part. The rotational speed detection part and the steering detection part are both arranged on the inner tub and are respectively used to acquire the rotational speed and steering of the inner tub. The main control part is used to control the steering and rotational speed of the rotating assembly 1 according to the detection results of the rotational speed detection part and the steering detection part.

[0054] Using the image acquisition device provided by an embodiment of the present invention, the main control component can accurately control the rotation speed and direction of the rotating component 1 according to the real-time data provided by the rotation speed detection component and the rotation direction detection component, so that it is synchronized with the inner barrel. By synchronously rotating the camera 71 provided on the rotating component 1 with the inner barrel, it is ensured that even at high rotation speeds, the camera 71 can capture clear and non-blurred images, greatly improving the accuracy of image recognition, which is crucial for the accurate judgment of materials, colors, and stains, ensuring that the most valuable information can be captured in each shot, avoiding invalid or repeated image acquisitions, thereby improving the overall intelligent level, and this process is automated, reducing manual intervention and greatly enhancing the intelligence and working efficiency of the system. Therefore, through the image acquisition device provided by this embodiment, the problem of blurred images inside the inner barrel of the washing and drying equipment in the prior art can be solved.

[0055] Specifically, the washing and drying equipment includes a washing machine, a dryer, and a washing and drying integrated machine. When the washing and drying equipment is a drum washing machine or a dryer, the fixing component 2 is used to be installed on the front door of the washing and drying equipment, and the front door is provided to be openable and closable to put in or take out the clothes inside the inner barrel. When the washing and drying equipment is a pulsator washing machine, the fixing component 2 is used to be installed on the machine cover of the washing and drying equipment, and the machine cover of the washing and drying equipment is located above the body and is provided to be openable and closable to put in or take out the clothes inside the inner barrel. Such a setting facilitates the daily maintenance and inspection of the image acquisition device, and at the same time ensures that the camera 71 can observe the inner barrel without obstruction, improving the convenience of image acquisition.

[0056] Specifically, the rotation speed detection component, the rotation direction detection component, and the rotating component 1 are all signal-connected to the main control component. The instant signal interaction helps to quickly respond to the changes in the inner barrel state, ensuring image acquisition at the best time and enhancing the overall response speed and efficiency of the system.

[0057] Specifically, the image acquisition device further includes a driving part 4. The driving part 4 is arranged on the fixing component 2, and the driving end of the driving part 4 is rotatably arranged, and the driving end is drivingly connected to the rotating component 1; the driving part 4 is connected to the main control component. With such a structural setting, through the driving connection between the driving end of the driving part 4 and the rotating component 1, the smooth rotation of the camera 71 is ensured, avoiding losses or unstable factors during the power transmission process.

[0058] Specifically, the driving part 4 is signal-connected to the main control component. In this way, the signal connection between the driving part 4 and the main control component realizes the precise regulation of the motion state of the rotating component 1. The main control component can adjust the output of the driving part 4 in real time to ensure that the rotating component 1 is synchronized with the inner barrel, improving the intelligent level of image acquisition.

[0059] Specifically, the driving part 4 is a motor. The stator housing of the motor is fixedly arranged on the fixed component 2, and the rotating shaft 41 of the motor forms the driving end. With such a structural arrangement, the rotating shaft 41 of the motor serves as the driving end and is directly drivingly connected to the rotating component 1, providing smooth and precise rotational power, reducing energy loss and control delay during the power transmission process, and ensuring that the camera 71 can accurately follow the rotation of the inner barrel, thereby capturing clear images.

[0060] Specifically, the driving part 4 is a brushless motor. The use of a brushless motor eliminates the problem of brush wear in traditional brushed motors, reduces the equipment downtime caused by mechanical failures, and improves the reliability and durability of the device.

[0061] Specifically, the driving part 4 is a three-phase permanent magnet synchronous brushless motor. The inner barrel driving motor of the washing and drying device is also a three-phase permanent magnet synchronous brushless motor. With the support of a control system, a three-phase permanent magnet synchronous brushless motor can achieve high-precision speed and steering control. When the inner barrel driving motor is also a three-phase permanent magnet synchronous brushless motor, the matching degree between the two is high, making it easier to achieve synchronous control, reducing the complexity of the control algorithm, simplifying the system design, and at the same time maintaining the consistency and coordination within the system.

[0062] Specifically, the image acquisition device further includes a connecting member 5. The first connecting portion of the connecting member 5 is connected to the rotating component 1, and the second connecting portion of the connecting member 5 is connected to the driving end. The first connecting portion and the second connecting portion are arranged and connected along the extending direction from the rotating component 1 to the fixed component 2. With such a structural arrangement, the rotating component 1 is tightly connected to the driving end through the connecting member 5, ensuring the mechanical stability between the two, reducing the possible position offset or loosening under high-speed rotation or vibration conditions, and thus guaranteeing the accuracy and reliability of image acquisition.

[0063] Specifically, the connecting member 5 is a coupling. The coupling can absorb part of the vibration during the connection process, reduce the vibration and noise that may be generated during high-speed rotation, improve the overall stability of the washing and drying device and the quietness during operation, and enhance the user experience. And compared with direct rigid connection, the coupling can reduce the direct friction and wear between components, reduce the maintenance requirements and costs, and extend the service life of the image acquisition device.

[0064] As Figure 2 shown, the fixed component 2 and the rotating component 1 are connected by a brushless motor (driving part 4). The rotating component 1 is installed on the rotating shaft 41 of the brushless motor through a coupling. When the brushless motor rotates, the rotating component 1 can rotate.

[0065] In one embodiment, the driving part 4 is electrically connected to a power source. In this way, the driving part 4 can independently obtain a stable power supply. The independent electrical connection between the driving part 4 and the power source ensures the stable operation of the driving part 4, avoids the interruption of synchronous rotation caused by power problems, and enhances the stability and reliability of the image acquisition device in complex environments.

[0066] In one embodiment, the image acquisition device further includes a power transmission member 61 and a power receiving member 62. The power transmission member 61 is disposed on the fixed component 2, and the power receiving member 62 is disposed on the rotating component 1. The power receiving member 62 is connected to the power storage member 8 to supply power to the power storage member 8. Among them: the power transmission member 61 is used to connect to a power source, and both the power transmission member 61 and the power receiving member 62 are power coils. With such a structural arrangement, the use of power coils realizes wireless power transmission, avoids complex wire winding and wear problems, improves the mobility and durability of the image acquisition device inside the washing and drying equipment. The design of the power coils also reduces the spatial requirements for physical connections, helps to reduce the overall size of the image acquisition device, and makes it more suitable for installation and use in a compact environment. In addition, wireless power transmission reduces the risk of direct contact between electrical components, improves the safety of the electrical system inside the washing and drying equipment, and reduces the possibility of electric shock and other electrical accidents.

[0067] In one embodiment, the image acquisition device further includes a power transmission member 61 and a power receiving member 62. The power transmission member 61 is disposed on the fixed component 2, and the power receiving member 62 is disposed on the rotating component 1. The power receiving member 62 is connected to the power storage member 8 to supply power to the power storage member 8. Among them: the power transmission member 61 is a permanent magnet, and the power receiving member 62 is an induction coil. With such a structural arrangement, the induction coil on the rotating component 1 cuts the magnetic field generated by the permanent magnet, and electricity is generated using the principle of electromagnetic induction to supply power to the power storage member 8. It is suitable for components that need to rotate, avoids the limitations of traditional wires, and can achieve high-efficiency energy conversion.

[0068] In one embodiment, the image acquisition device further includes a power transmission member 61 and a power receiving member 62. The power transmission member 61 is disposed on the fixed component 2, and the power receiving member 62 is disposed on the rotating component 1. The power receiving member 62 is connected to the power storage member 8 to supply power to the power storage member 8. Among them: the power transmission member 61 is used to connect to a power source, the power transmission member 61 is a power supply slide rail, and the power receiving member 62 is a contact brush. With such a structural arrangement, the combination of the power supply slide rail and the contact brush provides direct and stable electrical contact, ensuring the reliability of power transmission. Compared with wireless transmission, this direct contact power transmission method is more efficient under high power requirements and can meet the power requirements of the image acquisition device in application scenarios such as strong light filling and long exposure.

[0069] Specifically, the fixing component 2 includes a main housing which has a first installation cavity. The power transmission member 61 is disposed in the first installation cavity. The driving part 4 further includes a motor driver 13 which is disposed in the first installation cavity and is used to drive the rotation of the driving end. The power transmission member 61 has an inversion part for converting direct current into alternating current. With such a structural arrangement, placing the power transmission member 61 and the motor driver 13 in the first installation cavity helps to achieve reasonable utilization of the internal space of the device, reduces the need for additional installation space, makes the overall design more compact, and is easy to integrate into the existing structure of the washing and drying device.

[0070] Specifically, the washing and drying device includes a main control electrical box 3 which is disposed on the device body 14 of the washing and drying device. The main control electrical box 3 is used to supply power to the image acquisition device, send data broadcasts, and collect the image data captured by the image acquisition device. The power transmission structure of the image acquisition device is as follows: The main control electrical box 3 supplies power to the fixing component 2 through a power line. The power coil transmission end (power transmission member 61) on the fixing component 2 can perform inversion, thereby completing the conversion of direct current to alternating current. The brushless motor driver (motor driver 13) on the fixing component 2 operates using the electrical energy transmitted by the main control electrical box 3, thereby driving the rotation of the brushless motor. After the power coil receiving end (power receiving member 62) on the rotating component 1 receives the alternating current transmitted from the power coil transmission end (power transmission member 61), it rectifies and filters it to complete the conversion of alternating current to direct current, and simultaneously charges the power storage device (power storage member 8). In this way, through the interaction between the power coil transmission end and the receiving end, wireless power transmission between different components of the image acquisition device is achieved, avoiding complex wire connections between the rotating component 1 and the fixing component 2, and reducing the risks of wire wear and faults.

[0071] As Figure 1 shown, the fixing component 2 is installed on the front door glass bowl of the drum washing machine. The main control electrical box 3 and the fixing component 2 are connected by a transmission line 11 which includes a power line and a data line, and the main control electrical box 3 and the fixing component 2 are connected by a rotating hinge 12. The fixing component 2 is directly installed on the front door glass bowl of the drum washing machine, which not only provides an easily installable physical position, but also ensures that the camera 71 can observe the inner tub without obstruction, improving the convenience of image acquisition and user-friendliness.

[0072] Specifically, the image acquisition device further includes a fill light 72 and a power storage component 8. The fill light 72 is disposed on the rotating assembly 1 and on one side of the camera 71. The fill light 72 is used to supplement light to the inner cavity of the inner tub. The power storage component 8 is disposed on the rotating assembly 1. The input end of the power storage component 8 is used to be connected to a power source, and the output end of the power storage component 8 is used to be connected to the fill light 72 and / or the camera 71. With such a structural arrangement, the integrated design of the fill light 72 effectively improves the lighting conditions in the inner tub of the washing machine. Especially in low-light environments, it can ensure that the camera 71 obtains sufficient light, the captured images are highly clear, which is conducive to the accurate identification of the clothing state. The presence of the power storage component 8 enables the image acquisition device to independently store electrical energy and supply power to the fill light 72 and the camera 71 when needed, reducing the immediate dependence on external power sources and enhancing the autonomy and energy utilization efficiency of the system. Moreover, the setting of the power storage component 8 enables the image acquisition device to quickly respond to the light supplement and shooting requirements within a short time. Even in the case of power fluctuations or temporary power outages inside the washing and drying equipment, it can ensure the smooth progress of key operations.

[0073] In one embodiment, the image acquisition device further includes a first transmission part 91 and a second transmission part 92 which are connected to each other. The first transmission part 91 is connected to the camera 71, and the second transmission part 92 is connected to the main control part, so as to transmit the image collected by the camera 71 to the main control part through the first transmission part 91 and the second transmission part 92. The first transmission part 91 is arranged on the rotating assembly 1, and the second transmission part 92 is arranged on the fixed assembly 2. Among them, the main control part includes a first control part 101 and a second control part 102. The first control part 101 is arranged on the rotating assembly 1, and the second control part 102 is arranged on the fixed assembly 2. The camera 71 and the first transmission part 91 are both connected to the first control part 101, and the second transmission part 92 is connected to the second control part 102. With such a structural arrangement, the data transmission of the image acquisition device can be realized through the coordinated cooperation between the first control part 101 and the second control part 102. When the main control electrical box 3 generates a synchronous shooting requirement, this requirement is transmitted to the second control part 102 through the transmission line 11. After receiving the synchronous shooting requirement broadcast, the second control part 102 starts the power transmission part 61 and the motor driver 13. The second control part 102 continues to obtain the data broadcast of the rotation speed and direction of the inner barrel of the washing and drying device sent by the main control electrical box 3, and sends a control signal to the brushless motor driver to adjust the rotation speed and direction of the brushless motor rotor, and tries to make the rotating assembly 1 rotate synchronously with the main barrel. The second control part 102 can send a shooting command to the camera 71 on the rotating assembly 1 through the second transmission part 92. After receiving the shooting command through the first transmission part 91, the first control part 101 on the rotating assembly 1 starts the imaging module 7 to take pictures. After stopping the synchronization, image data transmission is performed. Under the control of the first control part 101, the image data is transmitted to the second transmission part 92 through the first transmission part 91, and then forwarded by the second control part 102 to the main control electrical box 3. In addition, the split design of the first transmission part 91 and the second transmission part 92, as well as the connection method with their respective control parts, provide higher flexibility and possible future system expansion for the image acquisition device, and facilitate maintenance and upgrade.

[0074] Specifically, the camera 71 and the first transmission part 91 are both signal-connected to the first control part 101, and the main control part and the second transmission part 92 are both signal-connected to the second control part 102. In this way, wireless data transmission is realized, avoiding the situation that the data cable is worn during rotation due to the setting of the data cable, and ensuring the stability and reliability of data transmission.

[0075] In one embodiment, the image acquisition device further includes a first transmission part 91 and a second transmission part 92 which are connected to each other. The first transmission part 91 is connected to the camera 71, and the second transmission part 92 is connected to the main control part, so as to transmit the image acquired by the camera 71 to the main control part through the first transmission part 91 and the second transmission part 92. The first transmission part 91 is arranged on the rotating assembly 1, and the second transmission part 92 is arranged on the fixed assembly 2. Wherein, both the first transmission part 91 and the second transmission part 92 are wireless communication transceivers. In this way, wireless data transmission is realized, avoiding the situation that the data cable is worn during rotation due to the setting of the data cable, and ensuring the stability and reliability of data transmission.

[0076] Specifically, the rotating assembly 1 includes a body part which has a second installation cavity. The electricity storage part 8, the first transmission part 91 and the first control part 101 are all arranged in the second installation cavity. The image acquisition device further includes a camera driving part 73, and the driving end of the camera driving part 73 is movably arranged and is drivingly connected to the camera. With such a structural arrangement, placing the electricity storage part 8, the first transmission part 91 and the first control part 101 in the second installation cavity not only protects these sensitive components from environmental factors such as moisture inside the washing and drying equipment and collision with clothes, but also keeps the appearance of the device clean and compact, improving its survivability and aesthetics in a complex environment. At the same time, it can also simplify the layout of the internal circuit, reduce the complexity of communication between components, facilitate unified power management and data processing, and improve the response speed and control accuracy of the system.

[0077] Specifically, the output end of the electricity storage part 8 is used to be connected to the camera driving part 73 to supply power to the camera driving part 73. With such a structural arrangement, the electricity storage part 8 directly supplies power to the camera driving part 73, ensuring that the camera 71 has sufficient power support during image acquisition, which can ensure the normal operation of the camera 71 and improve the reliability and stability of image acquisition.

[0078] Specifically, the data transmission structure of the image acquisition device is as follows: The data transmission between the main control electrical box 3 and the fixed assembly 2 is completed through the transmission line 11. The second control part 102 on the fixed assembly 2 receives the data broadcast of the main control electrical box 3. The image data acquired by the camera is first transmitted to the first control part 101 through the camera driving circuit, and then sent to the second transmission part 92 through the first transmission part 91 under the control of the first control part 101. The second transmission part 92 hands over the received data to the second control part 102 for processing. The first transmission part 91 and the second transmission part 92 can complete wireless end-to-end data transmission. The image data processed by the second control part 102 can be sent to the main control electrical box 3 for use.

[0079] Such as Figure 3As shown in the figure, the hardware architecture of the image acquisition device includes a fixed component 2, a rotating component 1, and a brushless motor. The fixed component 2 is provided with a power transmission member 61, a second transmission part 92, a motor driver 13, and a second control member 102. The rotating component 1 is provided with a power receiving member 62, a first transmission part 91, a power storage member 8 (a storage battery or a super capacitor), a first control member 101, and a camera module 7. The camera module 7 is composed of a camera 71, a fill light 72, and a camera driver 73.

[0080] An embodiment of the present invention provides a washing and drying device, and the washing and drying device includes the above-provided image acquisition device.

[0081] By using the washing and drying device provided by an embodiment of the present invention, the main control member can accurately control the rotation speed and rotation direction of the rotating component 1 according to the real-time data provided by the rotation speed detection member and the rotation direction detection member, so that it is synchronized with the inner tub. By making the camera 71 provided on the rotating component 1 rotate synchronously with the inner tub, it is ensured that even at high rotation speeds, the camera 71 can capture clear and non-blurred images, greatly improving the accuracy of image recognition, which is crucial for the accurate judgment of materials, colors, and stains, ensuring that the most valuable information can be captured in each shot, avoiding invalid or repeated image acquisitions, thereby improving the overall intelligent level, and this process is automated, reducing manual intervention, and greatly enhancing the intelligence and working efficiency of the system. Therefore, through the washing and drying device provided by this embodiment, the problem that the images inside the inner tub of the existing washing and drying device are relatively blurred can be solved.

[0082] Specifically, the washing and drying device includes a washing machine, a dryer, and a washing and drying integrated machine. When the washing and drying device is a drum washing machine or a dryer, the fixed component 2 is used to be installed on the front door of the washing and drying device, and the front door is provided in an openable and closable manner to put in or take out the clothes inside the inner tub. When the washing and drying device is a pulsator washing machine, the fixed component 2 is used to be installed on the machine cover of the washing and drying device, and the machine cover of the washing and drying device is located above the body and is provided in an openable and closable manner to put in or take out the clothes inside the inner tub. Such a setting facilitates the daily maintenance and inspection of the image acquisition device, and at the same time ensures that the camera 71 can observe the inner tub without obstacles, improving the convenience of image acquisition.

[0083] As Figures 4 to 6 shown, an embodiment of the present invention provides an image acquisition control method, and the image acquisition control method is applicable to the above-mentioned image acquisition device. The image acquisition control method includes: obtaining the rotation speed and rotation direction of the inner tub of the washing and drying device to obtain a target rotation speed and a target rotation direction; making the rotating component 1 of the image acquisition device rotate at the target rotation speed and the target rotation direction; making the camera 71 of the image acquisition device perform image acquisition.

[0084] Using the image acquisition control method provided by an embodiment of the present invention, by synchronously rotating the camera 71 with the rotating assembly 1, even when the inner barrel rotates at a high speed, the camera 71 can avoid image blurring caused by relative movement, thereby significantly improving the quality of the image. The rotating assembly 1 tracks the rotation speed and rotation direction of the inner barrel in real time to ensure that the rotation of the camera 71 provided on the rotating assembly 1 precisely matches the rotation state of the inner barrel. This dynamic synchronization helps to capture clear and non-blurred images at any operation stage of the washing and drying device (including high-speed rotation). Therefore, through the image acquisition control method provided by this embodiment, the problem of relatively blurred images of the inner barrel of the washing and drying device collected in the prior art can be solved.

[0085] Specifically, before the camera of the image acquisition device performs image acquisition, the image acquisition control method further includes: obtaining the current rotation speed and current rotation direction of the rotating assembly 1; determining whether the current rotation speed and current rotation direction of the rotating assembly 1 are respectively consistent with the target rotation speed and target rotation direction, and controlling the opening and closing of the camera 71 according to the determination result. With such a setting, by determining the difference between the rotating assembly 1 and the target state, the opening and closing of the camera are determined, avoiding power waste in the non-synchronous state. Especially when the rotation speed difference is large, the camera 71 remains in the closed state until the rotating assembly 1 is adjusted to the target state. This intelligent control strategy helps to reduce the overall energy consumption and extend the service life of the electricity storage component.

[0086] It should be noted that the opening and closing of the camera 71 include the on state and the off state; when the camera 71 is in the on state, the camera 71 is in the shooting standby state, that is, it can start shooting immediately as long as it receives a shooting instruction; when the camera 71 is in the off state, the camera 71 is not powered on.

[0087] Specifically, the method for determining whether the current rotation speed and current rotation direction of the rotation assembly 1 are respectively consistent with the target rotation speed and target rotation direction, and controlling the opening and closing of the camera 71 according to the determination result includes: comparing the current rotation direction of the rotation assembly 1 with the target rotation direction; when the current rotation direction of the rotation assembly 1 is the same as the target rotation direction, comparing the current rotation speed of the rotation assembly 1 with the target rotation speed; when the difference between the current rotation speed and the target rotation speed of the rotation assembly 1 is less than or equal to a preset difference, keeping the camera 71 in the startup state; when the difference between the current rotation speed and the target rotation speed of the rotation assembly 1 is greater than the preset difference, keeping the camera 71 in the closed state and adjusting the rotation speed of the rotation assembly 1 so that the difference between the current rotation speed and the target rotation speed of the rotation assembly 1 is less than or equal to the preset difference; when the current rotation direction of the rotation assembly 1 is different from the target rotation direction, keeping the camera 71 in the closed state and adjusting the rotation direction of the rotation assembly 1 so that the current rotation direction of the rotation assembly 1 is the same as the target rotation direction. With such a setting, by monitoring and comparing the rotation assembly 1 with the target state in real time, the control system can be dynamically adjusted to ensure that the image acquisition device is always in the best working state at different stages of the operation of the washing and drying device. This dynamic adaptability is the basis for achieving efficient and high-quality image acquisition. The introduction of the preset difference allows for a certain range of rotational speed fluctuations, but at the same time ensures that such fluctuations do not affect the clarity of image acquisition. This control strategy reflects the need for precise control of the system and ensures the stability of image acquisition in practical applications. Specifically, when the current rotation direction of the rotation assembly 1 is inconsistent with the target rotation direction, the camera 71 remains in the closed state until the correct rotation direction adjustment is completed. This mechanism prevents invalid or incorrect image acquisition caused by incorrect rotation direction, improving the overall accuracy and efficiency of the system. The overall process does not require user intervention, simplifies the operation process, and enhances user satisfaction.

[0088] As Figure 6 shown, in order to determine whether the rotation direction and rotation speed of the rotation assembly 1 are respectively synchronized with the rotation direction and rotation speed of the inner tub, a synchronization status check needs to be performed. First, obtain the rotation speed ω1 and rotation direction N1 of the brushless motor, and the rotation speed ω2 and rotation direction N2 of the main tub (i.e., the inner tub). First, compare whether N1 and N2 are the same. If they are the same, calculate |ω1 - ω2|. Otherwise, mark that the synchronization status check fails. When N1 and N2 are the same, calculate whether |ω1 - ω2| is less than Δωmax (rotation speed difference margin). If the condition is met, it means that the synchronization status check passes. Otherwise, the synchronization status check fails.

[0089] It should be noted that the preset difference is the rotation speed difference margin, that is, the maximum rotation speed difference that can satisfy non-blurry photographed pictures, which is obtained through the actual installation and debugging of specific equipment.

[0090] Specifically, the preset difference is 0. In this way, inside the washing machine tub that is rotating at a high speed, the design with a preset difference of 0 enables the camera to accurately capture the instantaneous state during the rotation process, which is crucial for identifying fine clothing features, stain types, etc., improving the accuracy of image recognition. And through precise control, it ensures that a clear image can be successfully obtained each time a shot is taken, reducing the number of repeated shots due to synchronization errors, saving power resources, and at the same time accelerating the image data acquisition speed of the entire laundry process.

[0091] Specifically, after the camera 71 of the image acquisition device performs image acquisition, the image acquisition control method further includes: determining whether the camera 71 has completed shooting; when the camera 71 has completed shooting, stopping the rotation of the rotating assembly 1; when the camera 71 has not completed shooting, maintaining the current rotation speed and current rotation direction of the rotating assembly 1. With such a setting, the rotation of the rotating assembly 1 is immediately stopped after the camera 71 has completed shooting, avoiding unnecessary power consumption. At the same time, it can also reduce the unnecessary rotation of mechanical components, thereby reducing the wear of rotating components such as the rotating hinge 12 and the slide rail, and extending the service life of the image acquisition device and even the entire washing and drying equipment.

[0092] In an embodiment, the image acquisition device further includes a fill light 72. The fill light 72 is disposed on the rotating assembly 1 and on one side of the camera 71. The fill light 72 is used to fill light into the inner cavity of the inner tub; the image acquisition control method further includes: obtaining the light intensity inside the inner cavity of the inner tub; when the light intensity inside the inner cavity is less than the preset light intensity, turning on the fill light 72 to fill light into the inner cavity; when the light intensity inside the inner cavity is greater than or equal to the preset light intensity, turning off the fill light 72. With such a setting, by detecting the inner cavity light intensity and correspondingly turning on or off the fill light 72, the system can adaptively adjust the lighting conditions. Regardless of how the external light changes, it can ensure sufficient light required for image acquisition, improving the adaptability and flexibility of image acquisition. The fill light 72 automatically adjusts according to the light intensity, ensuring uniform lighting during the image acquisition process, improving the clarity and color accuracy of the image, playing a positive role in the recognition of clothing materials, colors, etc., and optimizing the overall image processing effect.

[0093] As Figure 5As shown in the figure, when the main control electrical box 3 generates a synchronous shooting requirement, this requirement is transmitted to the second control part 102 through the transmission line 11. After receiving the synchronous shooting requirement broadcast, the second control part 102 starts the power coil transmission end (power transmission part 61) and the brushless motor driver (motor driver 13). The second control part 102 continues to obtain the data broadcast of the rotation speed and rotation direction of the main barrel (the inner barrel of the washing and drying device) sent by the main control electrical box 3, and sends a control signal to the brushless motor driver to adjust the rotation speed and rotation direction of the brushless motor rotor, attempting to make the rotating assembly 1 rotate synchronously with the main barrel. When the synchronous state verification passes, the second control part 102 sends a shooting command to the camera 71 on the rotating assembly 1 through the second transmission part 92, otherwise it continues to attempt synchronization until the synchronous state verification passes. After the first control part 101 on the rotating assembly 1 receives the shooting command through the first transmission part 91, it starts the imaging module 7 for shooting. When the shooting is completed, the synchronization is stopped, otherwise it waits for the shooting process to be completed. After stopping the synchronization, image data transmission is performed. Under the control of the first control part 101, the image data is transmitted to the second transmission part 92 through the first transmission part 91, and then forwarded by the second control part 102 to the main control electrical box 3. Thus, the synchronous shooting process ends. In actual application, it is only necessary to make the angular velocity of the rotating assembly 1 consistent with that of the main barrel during the shooting period. Assuming that the exposure time is less than the main barrel rotation period, it means that the inner barrel has not rotated one full week within the time of taking one photo, and the synchronous rotating assembly 1 will also not rotate one full week. Assuming that the exposure time is greater than the main barrel rotation period, the barrel body may rotate several weeks during the period of taking one photo, and the rotating assembly 1 also has to continuously rotate the same number of turns following the barrel body.

[0094] An embodiment of the present invention provides an image acquisition control device. The image acquisition control device is applicable to the above-mentioned image acquisition control method. The image acquisition control device includes an acquisition unit, a first control unit, and a second control unit. The acquisition unit is used to acquire the rotation speed and rotation direction of the inner barrel of the washing and drying device to obtain a target rotation speed and a target rotation direction; the first control unit is used to make the rotating assembly 1 of the image acquisition device rotate at the target rotation speed and the target rotation direction; the second control unit is used to make the camera 71 of the image acquisition device perform image acquisition.

[0095] Using the image acquisition control device provided by an embodiment of the present invention, by synchronously rotating the camera 71 with the rotating assembly 1, even when the inner barrel rotates at a high speed, the camera 71 can avoid image blurring caused by relative movement, thereby significantly improving the quality of the image. The rotating assembly 1 tracks the rotation speed and direction of the inner barrel in real time to ensure that the rotation of the camera 71 provided on the rotating assembly 1 precisely matches the rotation state of the inner barrel. This dynamic synchronization helps to capture clear and non-blurred images at any operating stage of the washing and drying device (including high-speed rotation). Therefore, through the image acquisition control device provided by this embodiment, the problem of relatively blurred images inside the inner barrel of the washing and drying device in the prior art can be solved.

[0096] An embodiment of the present invention provides a non-volatile storage medium. The non-volatile storage medium includes a stored program, wherein when the program runs, it controls the device where the non-volatile storage medium is located to execute the above-mentioned image acquisition control method.

[0097] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0098] 1. When the barrel rotates at a high speed, by synchronously rotating the camera module 7 to lengthen the exposure time and increase the light input, the need for high-sensitivity parameters of the camera 71 at a high shutter speed is avoided, reducing the selection cost of the camera 71.

[0099] 2. The camera module 7 integrates a fill light 72. Therefore, when taking pictures inside the rotating barrel, the fill light 72 also rotates synchronously with the barrel, reducing the influence caused by light and shadow changes.
