[0003] However, cameras in existing technologies are usually fixed in the washing and drying equipment. The cameras cannot rotate with the inner drum, and the image sensor area of ​​the cameras used in washing and drying equipment is generally small. Therefore, their image dynamic range is limited and the high ISO image quality is poor. It is usually necessary to extend the exposure time to take pictures. This means that the camera can only obtain clear pictures when the drum is rotating at a low speed or stationary. Otherwise, the image will have motion blur, resulting in severely blurred images that make it difficult to identify the specific details of the clothes. Summary of the Invention

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] like Figures 1 to 3 As shown, an embodiment of the present invention provides an image acquisition device for acquiring internal images of the inner tub of a washer-dryer for holding clothes. The image acquisition device includes a rotating assembly 1, a fixed assembly 2, a rotation speed detection element, a direction detection element, and a main control element. A camera 71 for capturing images is mounted on the rotating assembly 1, and the camera 71 is positioned facing the inner cavity of the inner tub. The fixed assembly 2 is mounted on the washer-dryer; the rotating assembly 1 is rotatably mounted on the fixed assembly 2. The rotation speed detection element, the direction detection element, and the rotating assembly 1 are all connected to the main control element. The rotation speed detection element and the direction detection element are both mounted on the inner tub and are used to acquire the rotation speed and direction of the inner tub, respectively. The main control element controls the direction and rotation speed of the rotating assembly 1 based on the detection results of the rotation speed detection element and the direction detection element.

[0054] The image acquisition device provided in one embodiment of the present invention enables the main control unit to precisely control the rotation speed and direction of the rotating component 1 based on real-time data provided by the rotation speed detection component and the direction detection component, ensuring that it remains synchronized with the inner tub. By synchronizing the camera 71 mounted on the rotating component 1 with the inner tub, it is ensured that even at high speeds, the camera 71 can capture clear, blur-free images, greatly improving the accuracy of image recognition. This is crucial for the accurate judgment of materials, colors, and stains, ensuring that the most valuable information is captured in each shot, avoiding invalid or repetitive image acquisition, thereby improving the overall level of intelligence. Furthermore, this process is automated, reducing manual intervention and significantly enhancing the system's intelligence and work efficiency. Therefore, the image acquisition device provided in this embodiment can solve the problem of blurry images of the inner tub of washing and drying equipment in the prior art.

[0055] Specifically, the washer-dryer equipment includes washing machines, dryers, and washer-dryer combos. When the washer-dryer equipment is a drum washing machine or dryer, the fixing component 2 is installed on the front door of the washer-dryer equipment, and the front door is designed to open and close to allow for the insertion or removal of clothes from the inner drum. When the washer-dryer equipment is a top-loading washing machine, the fixing component 2 is installed on the lid of the washer-dryer equipment, and the lid is located above the machine body and is designed to open and close to allow for the insertion or removal of clothes from the inner drum. This design facilitates the daily maintenance and inspection of the image acquisition device, while also ensuring that the camera 71 can observe the inner drum without obstruction, thus improving the convenience of image acquisition.

[0056] Specifically, the speed detection element, steering detection element, and rotation assembly 1 are all signal-connected to the main control unit. Real-time signal interaction facilitates rapid response to changes in the inner drum's state, ensuring image acquisition at the optimal time and improving the overall system response speed and efficiency.

[0057] Specifically, the image acquisition device also includes a drive unit 4, which is mounted on the fixed component 2. The drive end of the drive unit 4 is rotatably mounted and is drivenly connected to the rotating component 1. The drive unit 4 is also connected to the main control component. With this structural arrangement, the drive end of the drive unit 4 is drivenly connected to the rotating component 1, ensuring the smooth rotation of the camera 71 and avoiding losses or instabilities during power transmission.

[0058] Specifically, the drive unit 4 is signal-connected to the main control unit. This signal connection between the drive unit 4 and the main control unit enables precise control of the motion state of the rotating component 1. The main control unit can adjust the output of the drive unit 4 in real time, ensuring that the rotating component 1 remains synchronized with the inner drum, thus improving the intelligence level of image acquisition.

[0059] Specifically, the drive unit 4 is a motor, with the stator housing of the motor fixedly mounted on the fixed assembly 2, and the motor shaft 41 forming the drive end. With this structural arrangement, the motor shaft 41, as the drive end, is directly connected to the rotating assembly 1, providing smooth and precise rotational power. This reduces energy loss and control delay during power transmission, ensuring that the camera 71 can accurately follow the rotation of the inner drum, thereby capturing clear images.

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

[0061] Specifically, drive unit 4 is a three-phase permanent magnet synchronous brushless motor. The inner drum drive motor of the washer-dryer is also a three-phase permanent magnet synchronous brushless motor. With the support of the control system, the three-phase permanent magnet synchronous brushless motor can achieve high-precision speed and direction control. When the inner drum drive 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 maintaining the consistency and coordination within the system.

[0062] Specifically, the image acquisition device also includes a connector 5. The first connecting part of the connector 5 is connected to the rotating component 1, and the second connecting part of the connector 5 is connected to the drive end. The first and second connecting parts are arranged and connected along the extension direction from the rotating component 1 to the fixed component 2. With this structural arrangement, the rotating component 1 and the drive end are tightly connected by the connector 5, ensuring the mechanical stability between the two and reducing possible positional shifts or loosening under high-speed rotation or vibration conditions, thereby ensuring the accuracy and reliability of image acquisition.

[0063] Specifically, connector 5 is a coupling. During connection, the coupling absorbs some vibration, reducing vibration and noise that may occur during high-speed rotation, improving the overall stability and quietness of the washer-dryer equipment, and enhancing the user experience. Furthermore, compared to a direct rigid connection, the coupling reduces direct friction and wear between components, lowering maintenance requirements and costs, and extending the service life of the image acquisition device.

[0064] like Figure 2 As shown, the fixed component 2 and the rotating component 1 are connected by a brushless motor (drive unit 4). The rotating component 1 is mounted on the shaft 41 of the brushless motor via a coupling. When the brushless motor rotates, the rotating component 1 rotates as well.

[0065] In one embodiment, the drive unit 4 is electrically connected to a power source. This allows the drive unit 4 to independently obtain a stable power supply. The independent electrical connection between the drive unit 4 and the power source ensures stable operation of the drive unit 4, avoids interruptions in synchronous rotation due to power supply issues, 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 component 61 and a power receiver 62. The power transmission component 61 is mounted on the fixed assembly 2, and the power receiver 62 is mounted on the rotating assembly 1. The power receiver 62 is connected to the energy storage component 8 to supply power to the energy storage component 8. The power transmission component 61 is used to connect to a power source, and both the power transmission component 61 and the power receiver 62 are power coils. This structural arrangement enables wireless power transmission using power coils, avoiding the problems of complex wire tangling and wear, and improving the mobility and durability of the image acquisition device within the washer-dryer equipment. The power coil design also reduces the space requirements for physical connections, helping to reduce the overall size of the image acquisition device, making it more suitable for installation and use in compact environments. Furthermore, wireless power transmission reduces the risk of direct contact with electrical components, improving the safety of the internal electrical system of the washer-dryer equipment and reducing the possibility of electric shock and other electrical accidents.

[0067] In one embodiment, the image acquisition device further includes a power transmission component 61 and a power receiver 62. The power transmission component 61 is mounted on the fixed assembly 2, and the power receiver 62 is mounted on the rotating assembly 1. The power receiver 62 is connected to the energy storage component 8 to supply power to the energy storage component 8. The power transmission component 61 is a permanent magnet, and the power receiver 62 is an induction coil. This structural arrangement allows the induction coil on the rotating assembly 1 to cut the magnetic field generated by the permanent magnet, generating electricity using the principle of electromagnetic induction to power the energy storage component 8. This design is suitable for components that require rotation, avoids the limitations of traditional wires, and enables high-efficiency energy conversion.

[0068] In one embodiment, the image acquisition device further includes a power transmission component 61 and a power receiver 62. The power transmission component 61 is mounted on the fixed assembly 2, and the power receiver 62 is mounted on the rotating assembly 1. The power receiver 62 is connected to the energy storage component 8 to supply power to the energy storage component 8. Specifically, the power transmission component 61 is used to connect to a power source and is a power supply slide rail, while the power receiver 62 is a contact brush. This structural arrangement provides direct and stable power contact through the combination of the power supply slide rail and the contact brush, ensuring reliable power transmission. Compared to wireless transmission, this direct contact power transmission method is more efficient under high power requirements and can meet the power needs of the image acquisition device in applications such as strong light supplementation and long exposure.

[0069] Specifically, the fixing component 2 includes a main housing with a first mounting cavity. A power transmission component 61 is disposed within the first mounting cavity. The drive unit 4 also includes a motor driver 13, which is also disposed within the first mounting cavity and is used to drive the rotation of the drive end. The power transmission component 61 has an inverter section for converting direct current to alternating current. This structural arrangement, placing the power transmission component 61 and the motor driver 13 within the first mounting cavity, helps to achieve rational utilization of the internal space of the device, reduces the need for additional installation space, makes the overall design more compact, and facilitates integration into the existing structure of washer-dryer equipment.

[0070] Specifically, the washer-dryer includes a main control electrical box 3, which is mounted on the machine body 14 of the washer-dryer. The main control electrical box 3 is used to supply power to the image acquisition device, send data broadcasts, and collect 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 fixed assembly 2 via a power line. The power coil transmission end (power transmission component 61) on the fixed assembly 2 can be inverted, thereby completing the conversion from DC to AC. The brushless motor driver (motor driver 13) on the fixed assembly 2 uses the power transmitted from the main control electrical box 3 to operate, thereby driving the rotation of the brushless motor. The power coil receiving end (power receiving component 62) on the rotating assembly 1 receives the AC power transmitted from the power coil transmission end (power transmission component 61), rectifies and filters it, completing the conversion from AC to DC, and simultaneously charging the energy storage device (energy storage component 8). In this way, through the interaction between the power coil transmitting end and the receiving end, wireless power transmission between different components of the image acquisition device is realized, avoiding the complex wire connection between the rotating component 1 and the fixed component 2, and reducing wire wear and the risk of failure.

[0071] like Figure 1 As shown, the fixing component 2 is installed on the front door glass bowl of the drum washing machine. The main control electrical box 3 is connected to the fixing component 2 via a transmission line 11, which includes a power line and a data line. The main control electrical box 3 and the fixing component 2 are connected via 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 easy physical location for installation, but also ensures that the camera 71 can observe the inner drum without obstruction, improving the convenience of image acquisition and user-friendliness.

[0072] Specifically, the image acquisition device also includes a supplementary light 72 and a power storage device 8. The supplementary light 72 is mounted on the rotating assembly 1 and located to one side of the camera 71, providing supplementary lighting to the inner cavity of the inner tub. The power storage device 8 is mounted on the rotating assembly 1, with its input terminal connected to a power source and its output terminal connected to the supplementary light 72 and / or the camera 71. This integrated design of the supplementary light 72 effectively improves the lighting conditions inside the washing machine tub, especially in low-light environments, ensuring sufficient light for the camera 71 to capture clear images and accurately identify the condition of the clothes. The power storage device 8 allows the image acquisition device to independently store electrical energy, powering the supplementary light 72 and camera 71 when needed, reducing immediate reliance on external power and enhancing the system's autonomy and energy efficiency. Furthermore, the power storage device 8 enables the image acquisition device to quickly respond to supplementary lighting and shooting needs, ensuring the smooth operation of critical functions even during power fluctuations or temporary power outages within the washing and drying equipment.

[0073] In one embodiment, the image acquisition device further includes a first transmission unit 91 and a second transmission unit 92 connected to each other. The first transmission unit 91 is connected to the camera 71, and the second transmission unit 92 is connected to the main control unit, so as to transmit the image acquired by the camera 71 to the main control unit through the first transmission unit 91 and the second transmission unit 92. The first transmission unit 91 is disposed on the rotating assembly 1, and the second transmission unit 92 is disposed on the fixed assembly 2. The main control unit includes a first control unit 101 and a second control unit 102. The first control unit 101 is disposed on the rotating assembly 1, and the second control unit 102 is disposed on the fixed assembly 2. The camera 71 and the first transmission unit 91 are both connected to the first control unit 101, and the second transmission unit 92 is connected to the second control unit 102. With this structural arrangement, data transmission of the image acquisition device can be achieved through the coordinated cooperation between the first control unit 101 and the second control unit 102. When the main control electrical box 3 generates a synchronous shooting request, it transmits this request to the second control unit 102 via transmission line 11. After receiving the synchronous shooting request broadcast, the second control unit 102 activates the power transmission unit 61 and the motor driver 13. The second control unit 102 continues to acquire the data broadcast of the inner drum speed and direction of the washer-dryer from the main control electrical box 3, and sends control signals to the brushless motor driver to adjust the speed and direction of the brushless motor rotor, attempting to synchronize the rotation of the rotating assembly 1 with the main drum. The second control unit 102 can send a shooting command to the camera 71 on the rotating assembly 1 via the second transmission unit 92. After receiving the shooting command via the first transmission unit 91, the first control unit 101 on the rotating assembly 1 activates the camera module 7 to shoot. After synchronization stops, image data is transmitted. Under the control of the first control unit 101, the image data is transmitted to the second transmission unit 92 via the first transmission unit 91, and then forwarded to the main control electrical box 3 by the second control unit 102. Furthermore, the separate design of the first transmission unit 91 and the second transmission unit 92, as well as the connection method with their respective control components, provides the image acquisition device with greater flexibility and possible future system expansion, facilitating maintenance and upgrades.

[0074] Specifically, both the camera 71 and the first transmission unit 91 are signal-connected to the first control unit 101, and both the main control unit and the second transmission unit 92 are signal-connected to the second control unit 102. This enables wireless data transmission, avoiding the wear and tear on data cables during rotation and ensuring the stability and reliability of data transmission.

[0075] In one embodiment, the image acquisition device further includes a first transmission unit 91 and a second transmission unit 92 connected to each other. The first transmission unit 91 is connected to the camera 71, and the second transmission unit 92 is connected to the main control unit, so as to transmit the image acquired by the camera 71 to the main control unit through the first transmission unit 91 and the second transmission unit 92. The first transmission unit 91 is disposed on the rotating assembly 1, and the second transmission unit 92 is disposed on the fixed assembly 2. Both the first transmission unit 91 and the second transmission unit 92 are wireless communication transceivers. This achieves wireless data transmission, avoiding the wear and tear of data cables during rotation, and ensuring the stability and reliability of data transmission.

[0076] Specifically, the rotating assembly 1 includes a main body with a second mounting cavity. The energy storage component 8, the first transmission unit 91, and the first control component 101 are all disposed within the second mounting cavity. The image acquisition device also includes a camera driver 73, the driving end of which is movably disposed and connected to the camera driver. This structural arrangement, placing the energy storage component 8, the first transmission unit 91, and the first control component 101 within the second mounting cavity, not only protects these sensitive components from environmental factors such as internal moisture and clothing impacts within the washer-dryer, but also maintains the cleanliness and compactness of the device's appearance, improving its survivability and aesthetics in complex environments. Simultaneously, it simplifies the internal wiring layout, reduces the complexity of inter-component communication, facilitates unified power management and data processing, and improves the system's response speed and control accuracy.

[0077] Specifically, the output terminal of the energy storage device 8 is connected to the camera driver 73 to supply power to the camera driver 73. With this structural arrangement, the energy storage device 8 directly supplies power to the camera driver 73, ensuring that the camera 71 has sufficient power support when acquiring images, guaranteeing the normal operation of the camera 71, and improving the reliability and stability of image acquisition.

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

[0079] like Figure 3As shown, the hardware architecture of the image acquisition device comprises a fixed component 2, a rotating component 1, and a brushless motor. The fixed component 2 includes a power transmission unit 61, a second transmission unit 92, a motor driver 13, and a second control unit 102. The rotating component 1 includes a power receiver 62, a first transmission unit 91, a power storage unit 8 (battery or supercapacitor), a first control unit 101, and a camera module 7. The camera module 7 consists 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, which includes the image acquisition device provided above.

[0081] The washer-dryer equipment provided in one embodiment of the present invention allows the main control unit to precisely control the rotation speed and direction of the rotating component 1 based on real-time data provided by the speed detection component and the direction detection component, ensuring synchronization with the inner tub. By synchronizing the rotation of the camera 71 mounted on the rotating component 1 with the inner tub, clear, blur-free images are captured even at high speeds, significantly improving image recognition accuracy. This is crucial for accurate judgment of materials, colors, and stains, ensuring that the most valuable information is captured with each shot, avoiding invalid or repetitive image acquisition, thereby improving the overall level of intelligence. Furthermore, this process is automated, reducing manual intervention and greatly enhancing the system's intelligence and work efficiency. Therefore, the washer-dryer equipment provided in this embodiment can solve the problem of blurry images of the inner tub captured in existing washer-dryer equipment.

[0082] Specifically, the washer-dryer equipment includes washing machines, dryers, and washer-dryer combos. When the washer-dryer equipment is a drum washing machine or dryer, the fixing component 2 is installed on the front door of the washer-dryer equipment, and the front door is designed to open and close to allow for the insertion or removal of clothes from the inner drum. When the washer-dryer equipment is a top-loading washing machine, the fixing component 2 is installed on the lid of the washer-dryer equipment, and the lid is located above the machine body and is designed to open and close to allow for the insertion or removal of clothes from the inner drum. This design facilitates the daily maintenance and inspection of the image acquisition device, while also ensuring that the camera 71 can observe the inner drum without obstruction, thus improving the convenience of image acquisition.

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

[0084] The image acquisition control method provided in one embodiment of the present invention, by synchronizing the rotation of the camera 71 with the rotating assembly 1, avoids image blurring caused by relative motion, even when the inner tub is rotating at high speed, thereby significantly improving image quality. The rotating assembly 1 tracks the rotational speed and direction of the inner tub in real time, ensuring that the rotation of the camera 71 mounted on the rotating assembly 1 precisely matches the rotational state of the inner tub. This dynamic synchronization helps to capture clear, blur-free images at any operating stage of the washer-dryer equipment (including high-speed rotation). Therefore, the image acquisition control method provided in this embodiment can solve the problem of blurry images inside the inner tub of washer-dryer equipment acquired in the prior art.

[0085] Specifically, before the camera of the image acquisition device acquires images, the image acquisition control method further includes: obtaining the current rotational speed and current direction of the rotating component 1; determining whether the current rotational speed and current direction of the rotating component 1 are consistent with the target rotational speed and target direction, respectively, and controlling the opening and closing of the camera 71 based on the determination result. This setup, by judging the difference between the rotating component 1 and the target state to determine the opening and closing of the camera, avoids power waste in asynchronous states. Especially when the speed difference is large, the camera 71 remains closed until the rotating component 1 adjusts to the target state. This intelligent control strategy helps reduce overall energy consumption and extend the service life of the energy storage device.

[0086] It should be noted that the camera 71 has an on state and an off state; when the camera 71 is on, the camera 71 is in a shooting standby state, that is, it can start shooting immediately as soon as it receives a shooting command; when the camera 71 is off, the camera 71 is not powered on.

[0087] Specifically, the method for determining whether the current rotation speed and current direction of the rotating component 1 are consistent with the target rotation speed and target direction, and controlling the opening and closing of the camera 71 based on the determination result, includes: comparing the current direction of the rotating component 1 with the target direction; when the current direction of the rotating component 1 is the same as the target direction, comparing the current rotation speed of the rotating component 1 with the target rotation speed; when the difference between the current rotation speed and the target rotation speed of the rotating component 1 is less than or equal to a preset difference, putting the camera 71 into the start state; when the difference between the current rotation speed and the target rotation speed of the rotating component 1 is greater than the preset difference, putting the camera 71 into the close state, and adjusting the rotation speed of the rotating component 1 so that the difference between the current rotation speed and the target rotation speed is less than or equal to the preset difference; when the current direction of the rotating component 1 is different from the target direction, putting the camera 71 into the close state, and adjusting the direction of the rotating component 1 so that the current direction of the rotating component 1 is the same as the target direction. By employing this setup, the control system can dynamically adjust itself through real-time monitoring and comparison of the rotating component 1 with the target state. This ensures that the image acquisition device remains in optimal working condition at different stages of the washing and drying equipment's operation, and this dynamic adaptability is the foundation for achieving efficient and high-quality image acquisition. The introduction of a preset difference allows for a certain range of rotational speed fluctuations, while ensuring that these fluctuations do not affect the clarity of the acquired images. This control strategy reflects the need for precise system control and ensures the stability of image acquisition in practical applications. Specifically, when the current rotation of the rotating component 1 is inconsistent with the target rotation, the camera 71 remains off until the correct rotation adjustment is completed. This mechanism prevents invalid or erroneous image acquisition due to incorrect rotation, improving the overall accuracy and efficiency of the system. The entire process requires no user intervention, simplifying the operation and enhancing user satisfaction.

[0088] like Figure 6 As shown, to determine whether the direction and speed of the rotating component 1 are synchronized with the direction and speed of the inner tub, a synchronization state check is required. First, obtain the speed ω1 and direction N1 of the brushless motor, and the speed ω2 and 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, the synchronization state check fails. If N1 and N2 are the same, calculate whether |ω1-ω2| is less than Δωmax (speed difference margin). If this condition is met, the synchronization state check passes; otherwise, it fails.

[0089] It should be noted that the preset difference is the speed difference margin, which is the maximum speed difference that can ensure that the captured photos are not blurry. It is obtained through the actual installation and debugging of the specific equipment.

[0090] Specifically, the preset difference value is 0. This 0-value design allows the camera to accurately capture the instantaneous state during the high-speed rotation of the washing machine drum. This is crucial for identifying minute details of clothing and types of stains, thus improving image recognition accuracy. Furthermore, precise control ensures that a clear image is successfully captured every time, reducing the number of repeated shots due to synchronization errors, saving power, and accelerating image data acquisition throughout the entire washing process.

[0091] Specifically, after the camera 71 of the image acquisition device acquires an image, the image acquisition control method further includes: determining whether the camera 71 has completed capturing an image; when the camera 71 has completed capturing an image, stopping the rotation of the rotating component 1; and when the camera 71 has not completed capturing an image, maintaining the current rotation speed and current direction of the rotating component 1. This setting immediately stops the rotation of the rotating component 1 after the camera 71 completes capturing an image, avoiding unnecessary power consumption. It also reduces unnecessary rotation of mechanical parts, thereby reducing wear on 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 washer-dryer equipment.

[0092] In one embodiment, the image acquisition device further includes a supplementary light 72, which is disposed on the rotating assembly 1 and located to one side of the camera 71. The supplementary light 72 is used to provide supplementary lighting to the inner cavity of the inner tub. The image acquisition control method further includes: acquiring the light intensity inside the inner cavity of the inner tub; when the light intensity inside the inner cavity is less than a preset light intensity, turning on the supplementary light 72 to provide supplementary lighting to the inner cavity; and turning off the supplementary light 72 when the light intensity inside the inner cavity is greater than or equal to the preset light intensity. With this configuration, by detecting the light intensity inside the cavity and turning the supplementary light 72 on or off accordingly, the system can adaptively adjust the lighting conditions, ensuring sufficient lighting for image acquisition regardless of changes in external light, thus improving the adaptability and flexibility of image acquisition. The supplementary light 72 automatically adjusts according to the light intensity, ensuring uniform lighting during the image acquisition process, improving image clarity and color accuracy, playing a positive role in the recognition of information such as clothing material and color, and optimizing the overall image processing effect.

[0093] like Figure 5As shown, when the main control electrical box 3 generates a synchronous shooting request, it transmits the request to the second control unit 102 via transmission line 11. After receiving the synchronous shooting request broadcast, the second control unit 102 activates the power coil transmission terminal (power transmission unit 61) and the brushless motor driver (motor driver 13). The second control unit 102 continues to acquire the main tub (inner tub of the washer-dryer) speed and direction data broadcast from the main control electrical box 3, and sends control signals to the brushless motor driver to adjust the speed and direction of the brushless motor rotor, attempting to make the rotating assembly 1 rotate synchronously with the main tub. When the synchronization status verification is successful, the second control unit 102 sends a shooting command to the camera 71 on the rotating assembly 1 via the second transmission unit 92; otherwise, it continues to attempt synchronization until the synchronization status verification is successful. After receiving the shooting command via the first transmission unit 91, the first control unit 101 on the rotating assembly 1 activates the camera module 7 to shoot. When the shooting is completed, synchronization stops; otherwise, it waits for the shooting process to complete. After synchronization stops, image data transmission begins. Under the control of the first control unit 101, the image data is transmitted from the first transmission unit 91 to the second transmission unit 92, and then forwarded by the second control unit 102 to the main control electrical box 3. This concludes the synchronized shooting process. In practical applications, it is only necessary to ensure that the angular velocity of the rotating component 1 matches that of the main barrel during the shooting period. If the exposure time is less than the main barrel's rotation period, it means that the barrel has not completed one rotation within the time it takes to take one photo, and the synchronized rotating component 1 will also not complete one rotation. If the exposure time is greater than the main barrel's rotation period, the barrel may rotate several times during the time it takes to take one photo, and the rotating component 1 must also rotate continuously with the barrel for the same number of rotations.

[0094] An embodiment of the present invention provides an image acquisition control device, which is applicable to the image acquisition control method described above. 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 direction of the inner tub of the washer-dryer equipment to obtain the target rotation speed and target direction; the first control unit is used to make the rotating component 1 of the image acquisition device rotate according to the target rotation speed and target direction; the second control unit is used to make the camera 71 of the image acquisition device perform image acquisition.

[0095] The image acquisition control device provided in one embodiment of the present invention, by synchronizing the rotation of the camera 71 with the rotating assembly 1, avoids image blurring caused by relative motion, even when the inner tub is rotating at high speed, thereby significantly improving image quality. The rotating assembly 1 tracks the rotational speed and direction of the inner tub in real time, ensuring that the rotation of the camera 71 mounted on the rotating assembly 1 precisely matches the rotational state of the inner tub. This dynamic synchronization helps to capture clear, blur-free images at any operating stage of the washer-dryer equipment (including high-speed rotation). Therefore, the image acquisition control device provided in this embodiment can solve the problem of blurry images inside the inner tub of washer-dryer equipment acquired in the prior art.

[0096] An embodiment of the present invention provides a non-volatile storage medium, which includes a stored program, wherein the program controls the device where the non-volatile storage medium is located to execute the above-described image acquisition control method during runtime.

[0097] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0098] 1. When the barrel rotates at high speed, the exposure time is lengthened and the amount of light is increased by synchronously rotating the camera module 7, which avoids the need for high ISO parameters of camera 71 at high shutter speeds and reduces the selection cost of camera 71.

[0099] 2. The camera module 7 integrates a fill light 72, so when taking photos inside the rotating barrel, the fill light 72 also rotates synchronously with the barrel, reducing the impact of changes in light and shadow.
