Description

Technical Field

[0001] The invention belongs to the field of human body size measurement, and in particular relates to a human body scanning measurement device and a measurement method thereof. Background Art

[0002] With the development of technology, anthropometry has evolved through two stages: contact-based manual measurement and non-contact anthropometry. Traditional contact-based manual measurement involves direct contact of measuring tools with the body. These methods are widely used due to their simplicity, affordability, and flexibility. However, the limitations of manual measurement, such as high subjectivity, slow speed, and high workload, have limited their future prospects in modern society, hindering their ability to meet the demands of today's high-efficiency, high-precision digital garment production.

[0003] Non-contact anthropometrics are primarily used in the customer-oriented electronically tailored clothing industry (E-MTM). This technology leverages the digitization of the human body to organically integrate anthropometrics, body type classification, clothing design, and production, achieving a fast, accurate, and efficient production model. Its primary principle is based on modern optics and incorporates computer vision, computer graphics, and information processing technologies. Non-contact anthropometrics are primarily categorized into three-dimensional and two-dimensional methods. Stereophotogrammetry, laser measurement, moiré fringe measurement, TC2 layered profilometry, and projected fringe phase measurement are currently the primary methods used in three-dimensional non-contact anthropometrics.

[0004] Compared to traditional anthropometric techniques, 3D anthropometric technology offers advantages in accuracy, speed, and consistency. It can accurately measure body shapes and curves that are difficult to measure using traditional methods. The measurement process is simple and requires less expertise than traditional measurement. Furthermore, measurement results can be directly transmitted via a computer to pattern design and automatic cutting systems, enabling continuous automation of anthropometric measurement, pattern design, and nesting and cutting.

[0005] Currently, most 3D measurement technologies use simple measuring devices with single functions that can only meet basic image capture requirements. They are unable to achieve certain required standing postures for certain shots, nor can they correct incorrect standing postures of the measured person, which affects the measurement results and leads to deviations in the obtained 3D dimensions of the human body. In addition, to obtain photos of the measured person from various angles, cameras are often required to be set up at multiple angles to obtain body measurement photos from various angles, which increases equipment costs.

[0018] A measuring method of a human body scanning measuring device, characterized by comprising the following steps:

[0019] (1) The person being measured wears the measuring shoes and stands in the foot groove, making sure that he or she stands steadily;

[0020] (2) The person being measured raises both hands, and the measurement operator operates the handheld remote control to control the motor to start forward rotation through the centralized controller, pushing the slide and the armpit support toward the person being measured. When the inner end of the armpit support is close to the body of the person being measured, the rotating motor is turned off; the height of the armpit support is adjusted by the pneumatic rod assembly, and its top end is used to support the armpit of the person being measured. Then, both hands are lowered to the inclined surface of the armpit support, at which point the arms are at a 20° angle to the body;

[0021] (3) Unscrew the knurled knob to move the armpit support out from the front of the platform, and ask the person being measured to maintain the current posture so that the arm and body are at a 20° angle. In addition, the measurement operator uses the handheld remote control to control the rotary motor to reverse and start through the centralized controller, pushing the slide to reset.

[0022] (4) the measurement operator operates the handheld remote controller to scan the camera to take a photo of the front of the measured person;

[0023] (5) with the front of the measured person as 0°, the base is provided with spring switches at 0°, 45°, 90°, 135°, 180°, 225°, 270° and 315° respectively, and the electromagnet of the rotating table is located at the 0° position and is aligned with the 0° spring switch; the measurement operator operates the handheld remote controller to start the rotating motor and the electromagnet through the centralized controller, to drive the rotating table to rotate; when the rotating table rotates to 45°, the electromagnet attracts the spring switch and pulls it out, and the pressure sensor of the spring switch does not identify the pressure signal, the centralized controller closes the rotating motor, and the measured person is at the 45° direction, at this time the measurement operator operates the handheld remote controller to scan the camera to take a photo 2 of the measured person at the 45° position; then the measurement operator operates the handheld remote controller to start the rotating motor again through the centralized controller; when the rotating table rotates to 90°, the rotating motor is closed in the same control mode, and the scanning camera takes a photo 4 of the measured person at the 45° position; in this way, photos 3, 4, 5, 6, 7 and 8 of the measured person at the 90°, 135°, 180°, 225°, 270° and 315° positions are taken respectively, and finally the position is reset to the 0° position;

[0024] (7) the height of each part of the measured person is determined through the photos taken above, and the corresponding human body size is obtained by intercepting the height corresponding to the three-dimensional human body model obtained by scanning.

[0025] Due to the above technical scheme, the following beneficial effects are achieved:

The measuring table is designed as a rotating table structure, which is driven to rotate by a rotating mechanism. During the rotation, photos of the measured person at various angles are taken, and the photo shooting operation can be completed by one camera, which is convenient, fast and saves equipment cost. In addition, the armpit support is arranged to limit the arm opening degree of the measured person, so that the measured person can stand as required, and the measurement accuracy is improved, and accurate three-dimensional human body size is obtained.

[0028] The handheld remote controller can be used to control each component, so that the measurement operator can remotely control the measurement and photo shooting operation.

[0029] The present invention realizes the function of lifting and lowering the armpit support through a pneumatic rod assembly, and the control is completed by manual adjustment. It has a simple structure and is easy to operate. Through lifting and lowering adjustment, the armpit support is suitable for persons of different heights, ensuring that the arm of each person being measured is at 20 degrees to the body, limiting the standing posture of the person being measured, and improving measurement accuracy.

[0030] The slide is used to drive the armpit support to move horizontally left and right, making the armpit support suitable for people with different body widths, limiting the angle between their arms and the body to 20°. The structural design is ingenious, with a wide range of uses and strong practicality.

[0031] The present invention controls the lateral movement of the slide table by pushing the structure, and completes the armpit support toward the measured person in an electronically controlled manner, without the need for manual operation, saving time and effort, and being convenient and fast.

[0032] The present invention uses a bidirectional worm gear to synchronously transmit rotational motion to both ends, allowing the lead screw, slider, guide rod, and slide to operate synchronously. The armpit supports on both sides can be synchronously moved toward the person being tested, completing the operation simultaneously. This eliminates the need for separate left and right operation, making it easy to operate. The lead screw converts rotational motion into linear motion, which is then transmitted by the slider and guide rod, resulting in an ingenious structural design.

[0033] The present invention realizes the fixed-angle rotation of the turntable through an electromagnet and a spring switch. Its working principle is as follows: the spring switch is respectively arranged at eight positions of the base, namely 0° (front), 45°, 90°, 135°, 180°, 225°, 270° and 315°. When the electromagnet passes through the above positions, due to the strong magnetic attraction of the electromagnet, the button plate of the spring switch is sucked upward, and the switch rod is driven to lift, the spring is stretched, the switch rod is disengaged from the pressure sensor, and the centralized controller does not receive the signal of the pressure sensor, and turns off the rotating motor. At this time, the turntable stops at the current position, and the scanning camera takes a photo of the current position; the rotating motor can be started again by using a handheld remote control, thereby realizing a fixed-angle and quantitative rotation action, facilitating the taking of photos of the measured person at the rated angle, and the angle control is precise.

[0034] The present invention provides a certain pulling force to the person being measured through the second magnet of the foot groove and the third magnet of the measuring shoe, so that the person being measured can maintain the current position and current standing posture, thereby preventing the person from moving and affecting the measurement effect.

[0048] The present invention aims to provide a human body scanning and measurement device and a measurement method thereof. To address the shortcomings of the prior art, the measuring platform is designed as a turntable structure, which is driven to rotate by a rotating mechanism. During the rotation process, photos of the person being measured are taken from various angles. The shooting operation can be completed by a single camera, which is convenient and fast, and saves equipment costs. In addition, armpit supports are provided to limit the degree of arm extension of the person being measured, allowing the person being measured to assume the required standing posture, thereby improving measurement accuracy and obtaining accurate three-dimensional human body dimensions.

[0049] The following is combined with Figures 1 to 12 , the present invention is elaborated in detail:

[0050] A human body scanning and measuring device includes a turntable system and a scanning and measuring system. The turntable system includes a base 1, a turntable 2 and a centralized controller 9. The base 1 is equipped with a rotating mechanism 11, which is connected to the turntable 2 through a rotating shaft 5 and is used to drive the entire turntable 2 to rotate. The rotating mechanism 11 is controlled by the centralized controller 9; a platform 23 is installed in the middle position of the turntable 2, and the measured person stands on the platform 23 and rotates with the platform 23; armpit supports 3 are respectively installed on both sides of the platform 23, and the armpit supports 3 are used to support the arms and are inserted into the armpit position. The longitudinal section of the top of the armpit support 3 has an angle of 20°, including a vertical downward longitudinal surface and an inclined surface at an angle of 20° to the longitudinal surface; after supporting the arm, the arm is placed on the inclined surface, the body leans against the longitudinal surface, and the angle at the armpit position is 20°. The armpit support 3 is connected to the platform 23 through a sliding structure and can slide horizontally left and right relative to the platform 23, so as to facilitate the adjustment of the lateral position of the armpit support 3.

[0051] Based on the above structure, the present invention ensures that the posture of the person being measured during scanning meets the standing posture requirements in GB-T 23698-2009 "General requirements for three-dimensional scanning human body measurement methods", that is, "standing with both feet parallel and about 200 mm apart. The upper arms are abducted at a 20° angle to the body."

[0052] The scanning measurement system includes a scanning camera 8, a camera bracket 6 and a handheld remote control 7. The camera bracket 6 is connected and fixed to the base 1. The scanning camera 8 is installed on the camera bracket 6. The scanning camera 8 faces the platform 23 (that is, toward the person being measured). The camera bracket 6 ensures that the scanning camera 8 has a certain distance from the turntable 2. The specific distance is based on whether the scanning camera 8 can capture the entire body of the person being measured. The present invention fixes the scanning camera 8 on the base 1, and it does not rotate with the turntable 2. It cooperates with the turntable 2 to take photos at various angles, which is a clever design.

[0053] The handheld remote control 7 remotely controls the scanning camera 8 and the centralized controller 9. This is achieved through infrared remote control technology. An infrared transmitter transmits infrared signals to the infrared receivers of the scanning camera 8 and the centralized controller 9, thereby achieving remote control. The present invention allows the handheld remote control 7 to control various components, making it convenient for measurement operators to remotely control and complete measurement and photography tasks.

[0054] A rotating mechanism 11 is mounted within the base 1. The rotating mechanism 11 includes a rotating motor 111, a speed reducer 112, a driving gear 113, a belt 114, and a driven gear 115. The rotating motor 111 is connected to the speed reducer 112, which is connected to the driving gear 113. The driving gear 113 and the driven gear 115 are driven by the belt 114. The driven gear 115 is upwardly connected to the rotating shaft 5. The rotating shaft 5 extends out of the base 1 and is connected to the turntable 2, which is driven by the rotating shaft 5. The rotating mechanism 11 of the present invention has a simple structure, an ingenious design, is easy to control, and is very practical. Through the transmission of the speed reducer 112, the driving gear 113, the belt 114, and the driven gear 115, the rotating shaft 5 obtains a slow rotation speed, which meets the design requirements, rotates smoothly, and has a low probability of failure.

[0055] The armpit support 3 includes a support part 31 at the upper end and a pneumatic rod assembly 32 at the lower end. The pneumatic rod assembly 32 adjusts the height of the support part 31. The pneumatic rod assembly 32 is provided with a control rod 33, and the pneumatic rod assembly 32 is controlled to rise and fall by the control rod 33. The present invention realizes the function of raising and lowering the armpit support 3 through the pneumatic rod assembly 32, and the control is completed by manual adjustment. The structure is simple and the operation is convenient. Through the lifting and lowering adjustment, the armpit support 3 is suitable for persons of different heights to be measured, ensuring that the arm of each person being measured is at 20° to the body, limiting the standing posture of the person being measured, and improving the measurement accuracy.

[0056] The sliding structure is a slide 4, and the pneumatic rod assembly 32 is installed on the slide 4; the slide 4 is in an inverted U-shape, and a U-shaped groove is formed at its bottom, and a slide groove 1 is provided on the inner wall of the U-shaped groove. The front and rear ends of the platform 23 are provided with a slide rail 1 232, and the slide rail 1 232 matches the slide groove 1; the front and rear ends of the platform 23 are also provided with a bracket 233, the bracket 233 is located below the slide 4, the bracket 233 is provided with a slide rail 2331, and the slide 4 is provided with a slide groove 2, and the slide rail 2331 matches the slide groove 2; the slide 4 is used to drive the armpit support 3 to move horizontally left and right, so that the armpit support 3 is suitable for measured persons with different body widths, limiting their arms to 20° with the body. The structural design is ingenious, the range of use is wide, and the practicality is strong.

[0057] The slide 4 is provided with a mounting slot 42 with an open front end, which mates with the base plate 34 of the pneumatic rod assembly 32. During installation, the armpit support 3 is pushed into place through the open front end of the mounting slot 42. Both the base plate 34 and the mounting slot 42 are provided with matching screw holes, which are screwed into the knurled knob 35 to secure the armpit support 3. The open mounting slot 42 does not affect the arm posture of the person being measured during removal of the armpit support 3, allowing the person to maintain this posture and complete the measurement. The knurled knob 35 is easy to screw in and out by hand, making it convenient to secure and remove the armpit support 3. The structure is simple and practical.

[0058] The slide 4 is provided with a connecting plate 41, which is bolted to a push plate 211. The push plate 211 is connected to a push mechanism 21. The push mechanism 21 is used to push the slide 4 to slide on the platform 23. The push mechanism 21 is controlled by a centralized controller 9. The push mechanism 21 of the present invention controls the lateral movement of the slide 4, and the armpit support 3 is moved toward the person being measured in an electronically controlled manner, without the need for manual operation, saving time and effort, and being convenient and quick.

[0059] Specifically, the pushing mechanism 21 is installed in the turntable 2, and includes a pushing motor 219, a bidirectional worm gear reducer 218, a screw 217, a screw nut 216, a nut seat 215, a connecting rod 214, a slider 213 and a guide rod 212. The pushing motor 219 is connected to the bidirectional worm gear reducer 218, and the bidirectional worm gear reducer 218 is connected to the screws 217 on both sides through the shafts 2181 at both ends. The screw 217 is equipped with a screw nut 216 and a nut seat 215. The nut seat 215 is connected to the slider 213 through the connecting rod 214. The slider 213 is connected to the guide rod 212. The guide rod 212 passes through the turntable 2 and is connected to the push plate 211. The present invention uses a bidirectional worm gear to synchronously transmit rotational motion to both ends, allowing the lead screw 217, slider 213, guide rod 212, and slide 4 to operate synchronously. The armpit supports 3 on both sides can be simultaneously moved toward the person being measured, completing the operation simultaneously. This eliminates the need for separate left and right operation steps, making the operation easier to operate. The lead screw 217 converts rotational motion into linear motion, which is then transmitted by the slider 213 and guide rod 212, resulting in an ingenious structural design.

[0060] Push plate 211 is equipped with a third slide groove, and turntable 2 is equipped with a third slide rail 2111. These two slide grooves mate with each other. Slider 213 is equipped with a fourth slide groove, and turntable 2 is equipped with a fourth slide rail. This auxiliary sliding structure, comprised of the third slide groove, third slide rail 2111, fourth slide groove, and fourth slide rail, reduces friction between push plate 211 and slider 213, improving smoothness and preventing jamming and other malfunctions.

[0061] An electromagnet 22 is provided at the lower end of the turntable 2 in an inverted T shape, with the magnetic end of the electromagnet 22 facing downward, and the electromagnet 22 is controlled by the centralized controller 9; a switch port 12 is provided at the upper end of the base 1 in a circumferential direction, and a spring switch 13 is provided in the switch port 12. The spring switch 13 includes a button plate 131, a spring 133, a switch seat 132 and a switch rod 134. The spring 133 is sleeved between the button plate 131 and the switch seat 132. A pressure sensor is installed in the switch seat 132. The button plate 131 is connected to the switch rod 134. The switch rod 134 is inserted into the switch seat 132 and presses the pressure sensor; a magnet 1311 is provided in the button plate 131. The magnet 1311 matches the electromagnet 22. The pressure sensor is connected and transmits signals to the centralized controller 9. The present invention realizes the fixed angle rotation of the turntable 2 through the electromagnet 22 and the spring 133 switch 13. Its working principle is as follows: the spring 133 switch 13 is respectively set at eight positions of 0° (front), 45°, 90°, 135°, 180°, 225°, 270° and 315° of the base 1. When the electromagnet 22 passes through the above positions, due to the strong magnetic attraction of the electromagnet 22, the button plate 131 of the spring 133 switch 13 is sucked upward, and the switch rod 134 is driven to lift, the spring 133 is stretched, the switch rod 134 is disengaged from the pressure sensor, and the centralized controller 9 does not receive the signal of the pressure sensor and turns off the rotating motor 111. At this time, the turntable 2 stops at the current position, and the scanning camera 8 takes a photo of the current position; the rotating motor 111 can be started again by the handheld remote control 7, thereby realizing a fixed angle and quantitative rotation action, which is convenient for taking photos of the measured person at the rated angle, and the angle control is precise.

[0062] The platform 23 is provided with foot grooves 231 spaced 200 mm apart and containing second magnets 2311. The platform system also includes a measuring shoe 234, with a third magnet 2341 positioned on the bottom. The second magnet 2311 and the third magnet 2341 mate with each other. The present invention applies a certain pulling force to the person being measured, using the second magnet 2311 in the foot groove 231 and the third magnet 2341 in the measuring shoe 234, enabling them to maintain their current position and posture, preventing movement that could affect the measurement.

[0063] A measuring method of a human body scanning measuring device comprises the following steps:

[0064] (1) The person being measured wears the measuring shoe 234 and stands in the foot groove 231, ensuring that he or she stands steadily;

[0065] (2) The person being measured raises both hands, and the measuring operator operates the handheld remote control 7, controls the push motor 219 to start forward rotation through the centralized controller 9, and pushes the slide 4 and the armpit support 3 toward the person being measured. When the inner end of the armpit support 3 is close to the body of the person being measured, the rotating motor 111 is turned off; the height of the armpit support 3 is adjusted by the pneumatic rod assembly 32, and the top end of the armpit support 3 is used to support the armpit of the person being measured, and then the hands are lowered to the inclined surface of the armpit support 3, at which time the arms are at a 20° angle to the body;

[0066] (3) Unscrew the knurled knob 35 to move the armpit support 3 out from the front end of the platform 23, and ask the person being measured to maintain the current posture so that the arm of the person being measured is at a 20° angle to the body; in addition, the measurement operator operates the handheld remote control 7 to control the rotary motor 111 to reverse and start through the centralized controller 9, pushing the slide 4 to reset;

[0067] (4) The measuring operator operates the handheld remote control 7, and the scanning camera 8 takes a frontal photo of the measured person;

[0068] (5) With the front of the person being measured as 0°, the base 1 is respectively installed with springs 133 switches 13 at 0°, 45°, 90°, 135°, 180°, 225°, 270° and 315°. The electromagnet 22 of the turntable 2 is located at 0°, aligned with the spring 133 switch 13 at 0°; the measuring operator operates the handheld remote control 7, and controls the rotation motor 111 and the electromagnet 22 to start through the centralized controller 9, driving the turntable 2 to rotate; when the turntable 2 rotates to 45°, the electromagnet 22 attracts the spring 133 switch 13 and pulls it out. The pressure sensor of the spring 133 switch 13 does not recognize the pressure signal, and the centralized controller 9 turns off the rotation motor 1 11. The measured person is at a 45° angle. At this time, the measurement operator operates the handheld remote control 7, and the scanning camera 8 takes a second photo of the measured person at a 45° angle. The measurement operator then operates the handheld remote control 7 to start the rotating motor 111 again through the centralized controller 9. When the turntable 2 rotates to 90°, the rotating motor 111 is turned off in the same control mode, and the scanning camera 8 takes a fourth photo of the measured person at a 45° angle. The same process is repeated to take photos of the measured person at positions of 90°, 135°, 180°, 225°, 270°, and 315°, respectively. Finally, the measurement operator resets the position to 0°.

[0069] (7) The height of each part of the person being measured is determined by the above-mentioned photographs, and the three-dimensional human body model obtained by scanning is intercepted at the corresponding height to obtain the corresponding human body size.

[0070] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are included within the scope of protection of the present invention.
