Description

Technical Field

[0001] This invention belongs to the field of human body posture measurement technology, and more specifically, it relates to a multifunctional intelligent measurement device for human body posture and body circumference. Background Technology

[0002] In the fields of modern health management, body shape correction, fitness and weight loss and rehabilitation medicine, human body posture parameters and body circumference data are important references for assessing the body shape status, tracking the trend of body changes, and formulating personalized training and rehabilitation plans. Precise and convenient intelligent detection technology of human body posture and body circumference can provide reliable data support for daily health monitoring, posture correction intervention, postoperative rehabilitation follow-up and professional body shape assessment.

[0003] The Chinese patent publication number is CN121265016A, which discloses a human body measuring device and its method of use. The human body measuring device of this invention can make the soft measuring tape close to the human body to be measured by the cooperation of the movable buckle and hook. It is convenient to use and has high measurement accuracy.

[0004] Existing human body shape and circumference measurement devices of the same type have the following disadvantages: Existing measurement structures rely on a limited range of data acquisition methods, often employing fixed-viewpoint modules. This requires the subject to manually rotate their body to display different angles in order to complete full-angle data acquisition. During this autonomous rotation, subjects are prone to foot slippage, torso swaying, and center of gravity shift, leading to inconsistent data benchmarks across different angles. This can result in point position shifts and point cloud misalignments during subsequent 3D reconstruction, affecting the accuracy of body circumference and posture assessments. Furthermore, autonomous turning presents challenges for individuals with lower limb mobility impairments or weak balance. Some wheelchair users and those undergoing lower limb surgery rehabilitation may even be unable to perform autonomous turning, making it difficult to complete measurements using existing devices. Consequently, the applicable population for these devices is somewhat limited. Most existing professional measuring devices are fixed vertical cabinet structures, with the overall support and standing platform fixed as one piece, which cannot be folded and stored. The overall size and weight of the device are generally large, requiring a lot of space for daily storage. When facing scenarios that require the transfer of the device, such as on-site measurement, community clinics, and mobile inspections of fitness venues, the integrated structure is difficult to transport by conventional means of transportation. Some detachable devices are cumbersome to disassemble and assemble, and the measurement benchmark needs to be recalibrated after disassembly and redeployment, which cannot be put into use quickly and limits the expansion of the device's application scenarios.

[0005] In view of this, we will study and improve the existing structure and its shortcomings to provide a multifunctional intelligent measurement device for human body shape and circumference, in order to achieve a more practical purpose. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a multifunctional intelligent measurement device for human body shape and circumference.

[0007] A multifunctional intelligent measurement device for human body posture and circumference includes a posture measurement data screen. The data screen has a detection platform mechanism for intelligent detection. The detection platform mechanism includes a measuring bracket, a folding storage slot, a built-in circular slot, and a standing detection platform. Two measuring brackets are fixedly installed on both sides of the posture measurement data screen. The folding storage slot is located between the two measuring brackets, and the built-in circular slot is located on the inner wall of the folding storage slot. The standing detection platform is rotatably installed on the inner wall of the built-in circular slot. An intelligent measurement probe is provided on the side of the posture measurement data screen. Each side of the two measuring brackets has a through-hole mounting circular slot, and two limiting slots are also through-holes on the side of the two measuring brackets. A clamp is formed between the two limiting slots. The angle is 90 degrees. The lower ends of the two measuring brackets are fixedly installed with first rollers. The two ends of the folding storage slot are fixedly installed with rotating shafts. The two rotating shafts are respectively rotatably installed through the inner sidewalls of the two mounting circular slots. The circumferential ends of the two rotating shafts are fixedly installed with mounting blocks. The side ends of the two mounting blocks are respectively opened with cylindrical slots. The inner sidewalls of the two cylindrical slots are respectively slidably installed through the limiting pins. The side ends of the two limiting pins are fixedly installed with pull plates. Springs are fixedly installed between the two pull plates and the mounting blocks. The ends of the two limiting pins are respectively located on the inner sidewall of one of the limiting slots. The upper end of the folding storage slot is also opened with two clearance slots. The side ends of the folding storage slot are fixedly installed with L-shaped side plates.

[0008] Preferably, an electric push rod is fixedly installed between the built-in circular groove and the L-shaped side plate, a second roller is fixedly installed at the lower end of the built-in circular groove, and an annular support plate is rotatably installed on the inner side wall of the built-in circular groove.

[0009] Preferably, a lower connecting ring is fixedly installed at the lower end of the standing testing platform, and multiple support rods are fixedly installed between the lower connecting ring and the annular support plate. A drive motor is fixedly installed on the inner side wall of the built-in circular groove, and the standing testing platform is fixedly installed at the output end of the drive motor.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a folding storage slot and a rotating shaft are used to achieve the flipping and unfolding of the testing platform mechanism. Traditional fixed human body measuring devices often adopt a cabinet structure with the bracket and base connected as one unit. The overall horizontal space occupied is fixed, requiring a large area for daily storage. When facing scenarios that require transportation, such as on-site measurement and community mobile testing, the whole machine is difficult to fit into the loading space of conventional vehicles, making it inconvenient to move and deploy. In this solution, the folding storage slot can be flipped around the measuring bracket via the rotating shaft. When not in use, the standing testing platform, built-in circular slot, and other load-bearing components can be stored together with the folding storage slot in the space between the two measuring brackets, reducing the overall horizontal volume occupied by the device. This not only reduces the space required for daily storage but also facilitates loading into conventional transport vehicles during transportation, adapting to more mobile usage scenarios and improving the device's scenario adaptability.

[0011] In this invention, a drive motor and a standing detection platform work together to rotate the subject at a constant speed to complete multi-directional data acquisition. Most existing measurement devices use fixed-view acquisition units, requiring the subject to rotate their body autonomously during measurement to present different orientations (front, side, back, etc.) to complete full-angle data acquisition. During autonomous rotation, foot slippage and torso swaying can easily occur, making it difficult to maintain a consistent spatial reference for different acquisition angles and placing certain demands on the subject's coordination. In this solution, the drive motor rotates the standing detection platform at a constant speed, allowing the subject to maintain a natural, still standing posture during measurement without needing to adjust their body orientation. This reduces the demands on the subject's coordination, and the relatively fixed position of the body relative to the platform reduces postural deviations caused by autonomous rotation, contributing to improved consistency of the multi-angle data reference.

[0012] In this invention, a ring-shaped support plate and support rods are used to form circumferential auxiliary support for the standing detection platform. If the standing detection platform relies solely on the central drive shaft for support and transmission, uneven force may occur when the platform edge bears the weight of the human body. Radial sway may occur during rotation, leading to slight displacement of the human body and affecting the stability of data acquisition. This application connects the lower ring under the standing detection platform with the ring-shaped support plate inside the built-in circular groove through multiple support rods, forming a multi-point sliding support structure in the circumference of the platform. This structure can distribute the load borne by the platform, improve the stability of the platform during rotation, reduce the relative displacement of the human body caused by platform sway, and ensure that the angle data collected by the intelligent measurement probe maintains a relatively uniform spatial reference. This reduces the interference of point offset on the measurement results and ensures the stability of the calculation results.

[0013] In this invention, an electric push rod and a built-in circular groove are used to move the standing detection platform closer to or further away from the intelligent measurement probe. The distance between the fixed-position measurement platform and the acquisition unit remains constant. When dealing with subjects of varying heights, taller individuals may have their heads and shoulders outside the acquisition field of view, while shorter individuals may be outside the optimal depth of field, affecting the completeness and clarity of data acquisition. In this solution, the electric push rod can push the built-in circular groove to move along the length of the folding storage slot, flexibly adjusting the relative distance between the human body and the acquisition unit. This allows for adjustment to a suitable acquisition range for subjects of different heights. Increasing the acquisition distance for taller individuals ensures the entire body falls within the acquisition field of view, reducing the loss of data on body parts; conversely, shortening the acquisition distance for shorter individuals improves the acquisition of body surface details, enhancing the device's adaptability to people of different heights.

[0014] In this invention, the weight of the human body on the standing testing platform is distributed by using a lower connecting ring and support rods. If the entire load of the standing testing platform is borne by the output shaft of the drive motor, the motor output shaft will be subjected to a large radial force for a long time, which will easily accelerate the wear of the transmission components and may affect the rotational accuracy and structural lifespan in the long run. This application uses a lower connecting ring to bear part of the load of the standing testing platform, and then transmits it to the annular support plate and the built-in circular groove through multiple support rods. This reduces the radial force on the output shaft of the drive motor, reduces the workload of the drive components, slows down the wear rate of the components, and helps to extend the service life of the drive components. At the same time, the multi-point load-bearing structure can also enhance the overall load-bearing rigidity of the standing testing platform, reduce the stress deformation of the platform, and provide a more stable standing base for the person being tested.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] Please see Figure 1 - Figure 8This invention provides a multifunctional intelligent measurement device for human body posture and circumference, including a posture measurement data screen 1. The posture measurement data screen 1 is equipped with a detection platform mechanism for convenient intelligent detection. The detection platform mechanism includes a measurement bracket 2, a folding storage slot 3, an internal circular groove 4, and a standing detection platform 5. Two measurement brackets 2 are fixedly installed on both sides of the posture measurement data screen 1. The folding storage slot 3 is located between the two measurement brackets 2. The internal circular groove 4 is located on the inner wall of the folding storage slot 3. The standing detection platform 5 is rotatably installed on the inner wall of the internal circular groove 4. An intelligent measurement probe 11 is provided on the side end of the posture measurement data screen 1. This device relies on the intelligent processing capability of the posture measurement data screen 1. In conjunction with the mechanical structure of the detection platform, the body posture measurement data screen 1 serves as the core of the device's control and data processing. It has a built-in data processing unit and display interface, and works with the intelligent measurement probe 11 set at the side end to complete the calculation of human body posture and circumference. The intelligent measurement probe 11 integrates a three-dimensional depth acquisition module and a visible light imaging module, which can simultaneously acquire depth and distance information and appearance contour information of the human body surface. During the calculation process, the intelligent measurement probe 11 first performs initial positioning of the human body standing in the detection area, identifies the overall contour of the human body and key skeletal nodes such as shoulders, hips, knees, and ankles, and after confirming that the human body is within the effective acquisition range, the full-angle data acquisition process is started. During the data acquisition phase, the intelligent measurement probe 11 continuously acquires point cloud data and image data of the human body from different positions at a set frequency. All the acquired raw data is transmitted in real time to the processing unit inside the body posture measurement data screen 1. The processing unit first performs preprocessing such as noise reduction and smoothing on the raw data to remove invalid data points caused by environmental interference. Then, based on the multi-view three-dimensional reconstruction algorithm, it stitches and merges the body surface data acquired from different angles into a complete three-dimensional digital model of the human body. On the basis of the three-dimensional model, the processing unit can automatically identify and mark the body circumference measurement points such as waist circumference, hip circumference, chest circumference, shoulder width, and leg circumference, and calculate the circumference values ​​of the corresponding positions along the body surface contour. For posture assessment, the processing unit uses the mid-sagittal plane and coronal plane of the human body as reference planes, compares the symmetry of key points of the bones on both sides, and calculates multiple posture parameters such as the difference in shoulder height, pelvic tilt angle, scoliosis trend, and head forward angle. Both measuring brackets 2 have mounting grooves 21 extending through their side ends. Two limiting slots 22 also extend through their side ends, with an included angle of 90 degrees between them. First rollers 23 are fixedly mounted on the lower ends of both measuring brackets 2. Rotating shafts 33 are fixedly mounted on both sides of the folding storage slot 3. The two rotating shafts 33 are respectively rotatably mounted through the inner walls of the two mounting grooves 21. Mounting blocks 34 are fixedly mounted on the circumferential ends of the two rotating shafts 33. Cylindrical grooves 35 extend through the side ends of the two mounting blocks 34. The inner sidewalls of the cylindrical grooves 35 are all slidably installed through the limiting pins 36. Pull plates 37 are fixedly installed on the side ends of the two limiting pins 36. Springs 38 are fixedly installed between the two pull plates 37 and the mounting block 34. The ends of the two limiting pins 36 are respectively located on the inner sidewall of one of the limiting grooves 22. Two clearance grooves 32 are also provided at the upper end of the folding storage groove 3. In the non-use state, the folding storage groove 3 is in a vertical storage state and is stored in the space between the two measuring brackets 2, thereby reducing the lateral size occupied by the device and facilitating storage and transportation. When the device is needed, the user first unfolds the folding storage slot 3. First, the user holds the pull plate 37 and pulls it away from the mounting block 34. The pull plate 37 causes the limiting pin 36, which is fixedly connected to it, to slide outward along the inner wall of the cylindrical groove 35. At this time, the end of the limiting pin 36 disengages from the inner wall of one of the originally engaged limiting grooves 22, releasing the angle lock between the folding storage slot 3 and the measuring bracket 2. Simultaneously, the spring 38 is stretched under the pulling action of the pull plate 37 and the mounting block 34, accumulating elastic restoring force to maintain the pulled state of the pull plate 37. The user then rotates the folding storage slot 3, using the two rotating shafts 33 as pivots, causing the entire folding storage slot 3 to rotate relative to the measuring bracket 2. The rotating shafts 33 are located inside the mounting circular groove 21. The wall rotates synchronously, providing stable rotational support for the flipping of the folding storage slot 3. When the folding storage slot 3 rotates to the 90-degree position, the mounting block 34 rotates 90 degrees synchronously with the rotating shaft 33. At this time, the end of the limiting pin 36 coincides with the position of another limiting slot 22 on the measuring bracket 2. The design of the two limiting slots 22 forming a 90-degree angle corresponds exactly to the two stable working states of the folding storage slot 3 in storage and unfolding. After confirming the alignment, the user releases the pull plate 37, and the stretched spring 38 begins to retract and reset, driving the pull plate 37 and the limiting pin 36 to move closer to the measuring bracket 2, so that the end of the limiting pin 36 is inserted into the inner wall of the other limiting slot 22, forming an angle lock again, and completing the unfolding and fixing of the folding storage slot 3. An L-shaped side plate 31 is fixedly installed on the side end of the folding storage slot 3. An electric push rod 42 is fixedly installed between the built-in circular slot 4 and the L-shaped side plate 31. A second roller 41 is fixedly installed on the lower end of the built-in circular slot 4. An annular support plate 43 is rotatably installed on the inner side wall of the built-in circular slot 4, which has scene adaptability.

[0019] Thirdly, after unfolding and fixing the folding storage slot 3, the front and rear positions of the standing testing platform 5 can be adjusted according to the height of the person being tested to match the effective detection range of the intelligent measuring probe 11. During the adjustment process, the electric push rod 42 installed between the built-in circular slot 4 and the L-shaped side plate 31 is activated. The telescopic end of the electric push rod 42 extends or retracts, driving the built-in circular slot 4 to move along the length direction of the folding storage slot 3. The second roller 41 at the lower end of the built-in circular slot 4 rolls synchronously inside the clearance slot 32, providing rolling support for the movement of the built-in circular slot 4, reducing the frictional resistance during the movement, and making the position... The adjustment process is smoother. When the person being tested is tall, the electric push rod 42 is controlled to move the built-in circular groove 4 away from the body measurement data screen 1, increasing the straight-line distance between the standing detection platform 5 and the intelligent measurement probe 11, so that the whole body can fall completely into the acquisition field of view of the intelligent measurement probe 11, avoiding data loss due to the top of the head or feet exceeding the acquisition range; when the person being tested is short, the electric push rod 42 is controlled to move the built-in circular groove 4 closer to the body measurement data screen 1, shortening the acquisition distance, improving the clarity of the acquisition of body surface details, and ensuring the accuracy of body circumference calculation. A lower connecting ring 52 is fixedly installed at the lower end of the standing detection platform 5. Multiple support rods 53 are fixedly installed between the lower connecting ring 52 and the annular support plate 43. A drive motor 51 is fixedly installed on the inner side wall of the built-in circular groove 4. The standing detection platform 5 is fixedly installed at the output end of the drive motor 51. After the position is adjusted, the person being tested can stand on the standing detection platform 5, maintain a natural and relaxed standard standing posture, and start the body posture measurement data screen 1 and the intelligent measurement probe 11. The intelligent measurement probe 11 first performs initial positioning of the human body. After confirming that the human body's standing position meets the collection requirements, it sends a start signal to the drive motor 51. Upon receiving the signal, the drive motor 51 begins to rotate at a constant speed. Its output drives the standing detection platform 5 to rotate synchronously. The lower connecting ring 52 at the bottom of the standing detection platform 5 rotates synchronously with the platform surface and slides on the annular support disk 43 via multiple support rods 53. The annular support disk 43 is fixedly installed on the inner side wall of the built-in circular groove 4, providing circumferential support during rotation. The drive motor 51 adopts a low-speed, high-torque drive form, and the rotation speed can be adjusted according to the acquisition requirements. The rotation rate matches the acquisition frame rate of the intelligent measurement probe 11, avoiding problems such as image blurring and excessive point cloud data intervals caused by excessive rotation speed, thus ensuring the continuity and accuracy of data acquisition. The multiple support rods 53 are evenly arranged along the circumference of the lower connecting ring 52, which can evenly transmit the pressure on the standing detection platform 5 to the annular support disk 43, preventing excessive local stress on the platform surface and tilting, further improving the stability during standing and rotation.

[0020] Working principle: The first step involves the device utilizing the intelligent processing capabilities of the body posture measurement data screen 1 in conjunction with the mechanical structure of the detection platform. The body posture measurement data screen 1 serves as the core of the device's control and data processing, with a built-in data processing unit and display interface. Together with the intelligent measurement probe 11 located at the side end, it completes the calculation of human body posture and circumference. The intelligent measurement probe 11 integrates a three-dimensional depth acquisition module and a visible light imaging module, enabling it to simultaneously acquire depth and distance information and appearance contour information of the human body surface. During the calculation process, the intelligent measurement probe 11 first performs initial positioning of the human body standing in the detection area, identifies the overall contour of the human body and key skeletal nodes such as the shoulders, hips, knees, and ankles, and after confirming that the human body is within the effective acquisition range, it initiates the full-angle data acquisition process. During the data acquisition phase, the intelligent measurement probe 11 continuously acquires point cloud data and image data of the human body from different positions at a set frequency. All the acquired raw data is transmitted in real time to the processing unit inside the posture measurement data screen 1. The processing unit first performs preprocessing such as noise reduction and smoothing on the raw data to remove invalid data points caused by environmental interference. Then, based on the multi-view 3D reconstruction algorithm, it stitches and merges the body surface data acquired from different angles into a complete 3D digital model of the human body. On the basis of the 3D model, the processing unit can automatically identify and mark the measurement points of body circumference such as waist circumference, hip circumference, chest circumference, shoulder width, and leg circumference, and calculate the circumference values ​​of the corresponding positions along the body surface contour. For posture assessment, the processing unit uses the midsagittal plane and coronal plane of the human body as reference planes, compares the symmetry of key points of the bones on both sides, and calculates multiple posture parameters such as the difference in shoulder height, pelvic tilt angle, scoliosis trend, and head forward angle. Finally, the body circumference data and posture assessment results are integrated and presented to the user through the display interface of the posture measurement data screen 1. In the conventional measurement mode, the person being measured needs to rotate their body to provide different angles for data collection.

[0021] The second step involves the folding storage slot 3 being vertically folded away from the measuring brackets 2 when not in use. This reduces the device's lateral footprint, facilitating storage and transport. When the device is needed, the user unfolds the folding storage slot 3 by grasping the pull plate 37 and pulling it away from the mounting block 34. The pull plate 37 causes the limiting pin 36, which is fixedly connected to it, to slide outward along the inner wall of the cylindrical groove 35. At this point, the end of the limiting pin 36 disengages from the inner wall of one of the previously engaged limiting grooves 22, releasing the angle lock between the folding storage slot 3 and the measuring bracket 2. Simultaneously, the spring 38 is stretched under the pull of the pull plate 37 and the mounting block 34, accumulating elastic restoring force to maintain the tension of the pull plate 37. In the pulled state, the user rotates the folding storage slot 3, using the two rotating shafts 33 as pivots, causing the entire folding storage slot 3 to rotate relative to the measuring bracket 2. The rotating shafts 33 rotate synchronously within the inner wall of the mounting groove 21, providing stable rotational support for the folding storage slot 3 to flip. When the folding storage slot 3 rotates to the 90-degree position, the mounting block 34 rotates 90 degrees synchronously with the rotating shafts 33. At this time, the end of the limiting pin 36 coincides with the position of another limiting slot 22 on the measuring bracket 2. The two limiting slots 22 are designed to form a 90-degree angle, which is just right. Corresponding to the two stable working states of the folding storage slot 3 (folded and unfolded), after confirming the alignment, the user releases the pull plate 37. The stretched spring 38 begins to retract and reset, causing the pull plate 37 and the limiting pin 36 to move closer to the measuring bracket 2. This allows the end of the limiting pin 36 to engage with the inner wall of another limiting slot 22, forming an angle lock again, completing the unfolding and fixing of the folding storage slot 3. After unfolding, the folding storage slot 3 is in a horizontal state, with the second roller 41 at its lower end in contact with the ground and the first roller at the lower end of the measuring bracket 2. The rollers 23 together form a multi-point support, which can not only improve the stability of the device placement, but also adjust the position of the device by pushing it through the rollers when short-distance movement is required. The limiting pin 36 and the limiting slot 22 adopt a snap-fit ​​locking structure, which is simple and reliable. No additional tools are required for operation. The user can complete the unfolding and storage operation with one hand, which improves the convenience of using the device. The first roller 23 and the second roller 41 are both made of silent and non-slip material, which can reduce noise when moving and provide a certain friction when measuring and placing, reducing the possibility of accidental slippage of the device. This application utilizes a folding storage slot 3 and a rotating shaft 33 to achieve the flipping and unfolding of the testing platform mechanism. Traditional fixed human body measuring devices often employ a cabinet structure where the bracket and base are integrated, resulting in a fixed overall lateral space requirement. This necessitates reserving a large area for daily storage, making it difficult to fit into the loading space of conventional vehicles for scenarios requiring transport, such as on-site measurements or community patrol inspections, thus hindering mobile deployment. In this solution, the folding storage slot 3 can be flipped around the measuring bracket 2 via the rotating shaft 33. When not in use, the standing testing platform 5, the built-in circular groove 4, and other load-bearing components can be stored together with the folding storage slot 3 in the space between the two measuring brackets 2, reducing the overall lateral volume of the device. This not only reduces the space required for daily storage but also facilitates loading into conventional transport vehicles during transport, adapting to more mobile usage scenarios and improving the device's adaptability.

[0022] The third step, after unfolding and fixing the folding storage slot 3, involves adjusting the front and rear positions of the standing testing platform 5 according to the height of the person being tested, to match the effective detection range of the intelligent measuring probe 11. During adjustment, the electric push rod 42 installed between the built-in circular slot 4 and the L-shaped side plate 31 is activated. The telescopic end of the electric push rod 42 extends or retracts, driving the built-in circular slot 4 to move along the length of the folding storage slot 3. The second roller 41 at the lower end of the built-in circular slot 4 rolls synchronously inside the clearance slot 32, providing rolling support for the movement of the built-in circular slot 4, reducing frictional resistance during movement, and making the position adjustment process smoother. When the person being tested is tall, the electric push rod 42 is controlled to move the built-in circular slot 4 away from the body posture measurement data screen 1. Increasing the straight-line distance between the standing detection platform 5 and the intelligent measuring probe 11 ensures that the entire human body falls completely within the acquisition field of view of the intelligent measuring probe 11, preventing data loss due to the head or feet exceeding the acquisition range. When the person being tested is short, the electric push rod 42 is controlled to move the built-in circular groove 4 towards the body posture measurement data screen 1, shortening the acquisition distance, improving the clarity of body surface details, and ensuring the accuracy of body circumference calculation. After the position adjustment is completed, the person being tested can stand on the standing detection platform 5, maintain a natural and relaxed standard standing posture, and start the body posture measurement data screen 1 and the intelligent measuring probe 11. The intelligent measuring probe 11 first performs initial positioning of the human body, and after confirming that the human body's standing position meets the acquisition requirements, it sends a start signal to the drive motor 51. Upon receiving the signal, the drive motor 51 begins to rotate at a constant speed. Its output drives the standing detection platform 5 to rotate synchronously. The lower connecting ring 52 at the bottom of the standing detection platform 5 rotates synchronously with the platform surface and slides on the annular support disk 43 via multiple support rods 53. The annular support disk 43 is fixedly installed on the inner side wall of the built-in circular groove 4, providing circumferential support during rotation. The drive motor 51 adopts a low-speed, high-torque drive form, and the rotation speed can be adjusted according to the acquisition requirements. The rotation rate matches the acquisition frame rate of the intelligent measurement probe 11, avoiding problems such as image blurring and excessive point cloud data intervals caused by excessive rotation speed, thus ensuring the continuity and accuracy of data acquisition. The multiple support rods 53 are evenly arranged along the circumference of the lower connecting ring 52, which can evenly transmit the pressure on the standing detection platform 5 to the annular support disk 43, preventing excessive local stress on the platform surface and tilting, further improving the stability during standing and rotation. The standing detection platform 5 drives the human body standing on the platform to rotate slowly and uniformly. During the rotation of the human body, the intelligent measurement probe 11 continuously collects human body surface data and key body point data from different angles at a set frame rate. All data is transmitted to the body measurement data screen 1 in real time for processing and three-dimensional reconstruction. As the human body rotates once, complete data from all directions, including the front, side, and back of the human body, can be collected, and finally, all body posture and body circumference parameters are calculated.After the measurement is completed, the drive motor 51 stops rotating, the person being tested steps off the standing testing platform 5, and the device can be folded and stored by reversing the unfolding operation, restoring it to a portable transport state; This application utilizes a drive motor 51 and a standing detection platform 5 to coordinate and drive the subject to rotate at a constant speed to complete multi-directional data acquisition. Most existing measurement devices employ fixed-view acquisition units, requiring the subject to rotate their body autonomously during measurement to present different orientations (front, side, back, etc.) to complete full-angle data acquisition. During autonomous rotation, foot slippage and torso swaying can easily occur, making it difficult to maintain a consistent spatial reference for different acquisition angles and placing certain demands on the subject's coordination. In this solution, the drive motor 51 drives the standing detection platform 5 to rotate at a constant speed, allowing the subject to maintain a natural, static standing posture during measurement without needing to adjust their body orientation. This reduces the demands on the subject's coordination, and the relatively fixed position of the body relative to the platform reduces postural deviations caused by autonomous rotation, contributing to improved consistency of multi-angle data references.

[0023] This application uses a ring-shaped support plate 43 and support rods 53 to provide circumferential auxiliary support for the standing detection platform 5. If the standing detection platform 5 relies solely on the central drive shaft for support and transmission, uneven force may occur when the platform edge bears the weight of the human body, potentially causing radial swaying during rotation and resulting in slight displacement of the human body, affecting the stability of data acquisition. This application connects the lower connecting ring 52 below the standing detection platform 5 to the ring-shaped support plate 43 inside the built-in circular groove 4 using multiple support rods 53, forming a multi-point sliding support structure in the circumference of the platform. This structure can distribute the load borne by the platform, improve the stability of the platform during rotation, reduce the relative displacement of the human body caused by platform swaying, and ensure that the angle data collected by the intelligent measuring probe 11 maintains a relatively uniform spatial reference, reducing the interference of point offset on the measurement results and ensuring the stability of the calculation results.

[0024] This application utilizes an electric push rod 42 and a built-in circular groove 4 to move the standing detection platform 5 towards or away from the intelligent measuring probe 11. The distance between the fixed-position measuring platform and the acquisition unit remains constant. When dealing with subjects of varying heights, taller individuals may have their heads and shoulders outside the acquisition field of view, while shorter individuals may be outside the optimal depth of field, affecting the completeness and clarity of data acquisition. In this solution, the electric push rod 42 can push the built-in circular groove 4 to move along the length of the folding storage groove 3, flexibly adjusting the relative distance between the human body and the acquisition unit. This allows for adjustment to a suitable acquisition range for subjects of different heights. Increasing the acquisition distance for taller individuals ensures the entire body falls within the acquisition field of view, reducing data loss in body parts; conversely, shortening the acquisition distance for shorter individuals improves the acquisition of surface details, enhancing the device's adaptability to different height groups.

[0025] This application utilizes a lower connecting ring 52 and support rods 53 to distribute the weight of the human body borne by the standing testing platform 5. If the entire load of the standing testing platform 5 is borne by the output shaft of the drive motor 51, the motor output shaft will be subjected to a large radial force for a long time, which will easily accelerate the wear of the transmission components and may affect the rotational accuracy and structural lifespan in the long run. This application uses the lower connecting ring 52 to bear part of the load of the standing testing platform 5, and then transmits it to the annular support plate 43 and the built-in circular groove 4 through multiple support rods 53. This reduces the radial force on the output shaft of the drive motor 51, reduces the workload of the drive components, slows down the wear rate of the components, and helps to extend the service life of the drive components. At the same time, the multi-point load-bearing structure can also enhance the overall load-bearing rigidity of the standing testing platform 5, reduce the stress deformation of the platform, and provide a more stable standing base for the person being tested.
