Description

Technical Field

[0001] This invention belongs to the field of human body data measurement technology, specifically relating to a non-contact human body data measurement device for clothing customization. Background Technology

[0002] Custom-made clothing is garments tailored to individual needs, meeting customers' personalized requirements. Taking measurements is an indispensable part of the clothing customization process. Methods for obtaining anthropometric data can be divided into contact and non-contact measurements. Traditional methods use measuring tools such as tape measures, angle gauges, and height measuring devices to obtain anthropometric data; this method falls under contact measurement. Current technologies also utilize measuring devices such as ultrasonic ranging devices or CCD and CMOS cameras to collect anthropometric data; these methods fall under non-contact measurement.

[0003] In non-contact measurement methods, when using cameras to measure data, the measuring device captures images of customers wearing customized clothing from multiple angles, collecting human body image information. By analyzing and summarizing this image information, human body feature curves are obtained, and a three-dimensional human body model is established. In this measurement scheme, the color difference between the background environment and the human image is related to the difficulty of extracting the human body feature curves. Existing measuring equipment is easily affected by the color of the customer's clothing and the color of the shooting background in practical applications, which can easily produce large errors in the process of extracting human body features, and the measurement accuracy needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a non-contact human body data measurement device for clothing customization in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A non-contact human body data measurement device for clothing customization includes a camera for collecting human body data and a position adjustment mechanism for adjusting the camera's shooting angle. A storage mechanism is located on one side of the position adjustment mechanism, and multiple background cloths of different colors are mounted on the storage mechanism. The human body data measurement device also includes a traction mechanism powered by the position adjustment mechanism. The storage mechanism is used to adjust the orientation of the background cloths so that one background cloth faces the traction mechanism. The traction mechanism connects the background cloths and positions them under the drive of the position adjustment mechanism. The measurement device collects human body data in a collection chamber. The position adjustment mechanism is installed on the ceiling wall of the collection chamber. The subject stands in the center of the platform, and human body image information is collected through the camera. Before collecting image information, a background cloth is selected based on the subject's clothing. During the selection process, a background cloth with a suitable color tone is rotated to face the traction mechanism via a storage mechanism. The traction mechanism then locks the end of the background cloth away from the axis of the storage mechanism. Next, the traction mechanism, driven by the position adjustment mechanism, performs a circular motion, causing the background cloth to unfold and surround the object being collected. When collecting human image information, the traction mechanism releases the lock on the background cloth. The position adjustment mechanism adjusts the shooting angle of the camera, and the camera surrounds the platform to collect multiple sets of human image information. The camera sends the human image information to the industrial control computer for image analysis. The industrial control computer analyzes the human image information and obtains human data. The position adjustment mechanism can adjust the shooting angle of the camera and, together with the traction and storage mechanisms, select and arrange a background cloth with a suitable color tone, reducing the difficulty for the industrial control computer to extract image features and improving measurement accuracy.

[0007] As a further optimization of the present invention, the position adjustment mechanism includes an annular guide rail, a mounting plate slidably disposed at the bottom end of the guide rail, a first motor fixed to one side of the mounting plate, a gear fixed to the output end of the first motor, and a gear ring located directly below the guide rail and meshing with the gear. The camera is disposed below the mounting plate, and both the camera and the traction mechanism are mounted on the mounting plate. When adjusting the camera angle and arranging the background cloth through the traction mechanism, the first motor drives the gear to rotate. Through the meshing of the gear and the gear ring, the first motor and the mounting plate drive the camera and the traction mechanism to move on the annular guide rail.

[0008] As a further optimization of the present invention, the position adjustment mechanism further includes a frame fixed to the bottom of the mounting plate and a lead screw motor fixed to one end of the frame. The output shaft of the lead screw motor is threadedly connected to a mounting base that is fixed to the camera. The mounting base is slidably connected to the frame. The lead screw motor drives the camera to slide up and down along the frame through the mounting base, thereby realizing the adjustment of the camera height.

[0009] As a further optimization of the present invention, the position adjustment mechanism further includes two mounting plates located on the inner and outer sides of the guide rail, respectively. The two mounting plates are fixed to the top of the mounting plate, and a guide wheel that fits against the guide rail is rotatably provided on the opposite side of the two mounting plates.

[0010] As a further optimization of the present invention, the storage mechanism includes a second motor, a top plate fixed to the output end of the second motor, a plurality of winding frames fixed to the bottom end of the top plate and arranged circumferentially along the top plate, a third motor fixed to the bottom end of the top plate and corresponding to each winding frame, and a rotating shaft fixed to the output end of the third motor and rotatably connected to the winding frames. The rotating shaft corresponds to each background cloth. Before acquiring human image information, the second motor drives the top plate to rotate, thereby rotating the winding frame carrying the background cloth with a suitable color difference to the side of the storage mechanism closer to the position adjustment mechanism, so that the traction mechanism can lock the background cloth.

[0011] As a further optimization of the present invention, the background cloth includes a cloth body wrapped around the outside of the rotating shaft and fixed at one end to the rotating shaft, and a guide rod fixed at the other end of the cloth body. A first electromagnet is provided on the guide rod, and a first hanging wheel is provided at the top of the guide rod. The traction mechanism includes a vertical plate fixed to the other side of the mounting plate, a limiting cover fixed to the end of the vertical plate away from the toothed ring, a second electromagnet fixed inside the limiting cover, and an annular slide rail concentric with the guide rail. The first electromagnet on each background cloth corresponds to the second electromagnet on the traction mechanism. When the background cloth is locked... When the second electromagnet is energized, the first electromagnet on the background cloth facing the traction mechanism is also energized. Through the mutual attraction between the second and first electromagnets, the guide rod at the end of the cloth body moves toward the vertical plate. When the first electromagnet is embedded in the limiting cover, the background cloth is locked. At this time, the first hanging wheel enters the annular slide rail. After the mounting disc rotates around the annular guide rail once, the first hanging wheel also rolls along the slide rail once. The guide rod drives the cloth body to rotate around the annular guide rail once, thereby unfolding the cloth body. After the first and second electromagnets are de-energized, the traction mechanism releases the locking of the background cloth.

[0012] As a further optimization of the present invention, the first electromagnet is fixed on the outside of the movable frame, and a limiting plate that is slidably connected to the movable frame is fixed on the guide rod. A spring is provided between the limiting plate and the movable frame. When the background cloth is locked, the first electromagnet and the second electromagnet attract each other, and the movable frame slides toward the side away from the limiting plate. When the background cloth is unlocked, the first electromagnet and the movable frame are reset under the action of the spring.

[0013] As a further optimization of the present invention, the end of the limiting cover away from the vertical plate is provided with a horn-shaped opening, which guides the first electromagnet and ensures that the first electromagnet can be smoothly embedded in the limiting cover.

[0014] As a further optimization of the present invention, the traction mechanism further includes an annular slide rail concentric with the guide rail. The slide rail has a notch on the side near the storage mechanism. An inlet track with one end tangent to the slide rail is provided on the notch. The other end of the inlet track is bent toward the storage mechanism. Second hangers are evenly arranged at the top of the fabric body. When the fabric body is unfolded by the traction mechanism, the second hangers are guided by the inlet track. The second hangers enter the annular slide rail along the inlet track to shape the fabric body.

[0015] As a further optimization of the present invention, a groove is provided on the bottom side of the winding frame near the guide rail. A limiting frame for constraining the guide rod is slidably connected to the inner side of the groove. A pressure sensor is fixed at the end of the groove away from the guide rod and spring-connected to the limiting frame. When the background fabric is stored, the third motor drives the rotating shaft to rotate, winding the fabric body to the outside of the rotating shaft. When storing the background fabric, the limiting frame intercepts the guide rod. When the fabric body is finished winding, the guide rod provides pressure to the pressure sensor through the limiting frame and the spring. When the pressure sensor detects that the pressure reaches the threshold, the third motor is turned off to avoid over-winding of the fabric body and ensure that the guide rod is in the same position after each storage.

[0016] The beneficial effects of this invention are as follows:

[0017] 1) This invention uses a camera in conjunction with an industrial control computer to collect and analyze human image information, thereby achieving non-contact measurement of human data. The position adjustment mechanism can adjust the camera's shooting angle and can work with the traction mechanism and storage mechanism to select and arrange a background cloth with a suitable color tone to ensure that the shooting background can form a sufficient color difference with the clothing worn by the data collection object, reducing the difficulty for the industrial control computer to extract image contour features and improving the measurement accuracy of the equipment.

[0018] 2) The present invention uses the attraction of the first electromagnet and the second electromagnet to move the guide rod at the end of the fabric body toward the vertical plate to lock the background fabric. The mounting plate drives the first hanging wheel to roll circumferentially along the annular slide rail. The guide rod unfolds the fabric body and surrounds the object to be collected. The spring between the limiting plate and the movable frame plays a reset role for the first electromagnet and the movable frame after the power is cut off, and provides a buffer when the guide rod stops rotating, reducing the stress generated at the connection between the fabric body and the guide rod and the rotating shaft, and extending the service life of the background fabric.

[0019] 3) The present invention sets an introduction track at the notch, one end of the introduction track is tangent to the slide rail and the other end is bent toward the storage mechanism. The second hanging wheel is evenly arranged at the top of the fabric body. When the fabric body is unfolded by the traction mechanism, the second hanging wheel is guided by the introduction track. The second hanging wheel enters the annular slide rail along the introduction track to fix the fabric body and prevent the background fabric from sliding down during shooting.

[0020] 4) When storing the background fabric, the present invention uses a limiting frame to intercept the guide rod. When the fabric body is finished winding, the guide rod provides pressure to the pressure sensor through the limiting frame and spring. When the pressure sensor detects that the pressure reaches the threshold, the third motor is turned off to avoid the fabric body from being over-wound. This ensures that the guide rod is in the same position after each storage, and ensures that sufficient magnetic force can be formed between the first electromagnet and the second electromagnet during each process of locking the background fabric.

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example

[0033] like Figure 1 As shown, a non-contact human body data measurement device for clothing customization includes a camera 1 for collecting human body data and a position adjustment mechanism 2 for adjusting the shooting angle of the camera 1. A storage mechanism 3 is provided on one side of the position adjustment mechanism 2, and multiple background cloths 4 of different colors are placed on the storage mechanism 3. When customizing clothing, the measurement device collects human body data in a collection chamber 6. The position adjustment mechanism 2 is installed on the top wall of the collection chamber 6. The subject stands in the center of a platform 7, which is directly below the position adjustment mechanism 2. The human body data measurement device also includes a traction mechanism 5 powered by the position adjustment mechanism 2. The storage mechanism 3 is used to adjust the orientation of the background cloths 4 so that one background cloth 4 faces the traction mechanism 5. The traction mechanism 5 connects the background cloths 4 and arranges them under the drive of the position adjustment mechanism 2. Human body image information is collected by the camera 1, preferably a CCD camera or a CMOS camera. Before collecting image information, a background cloth is selected according to the subject's clothing. During the selection process, the background cloth 4, which has a significant color difference from the clothing worn by the subject, is rotated by the storage mechanism 3 to face the traction mechanism 5. The traction mechanism 5 locks the end of the background cloth 4 away from the axis of the storage mechanism 3. Then, the traction mechanism 5 moves in a circular motion under the drive of the position adjustment mechanism 2. After the traction mechanism 5 rotates once, the background cloth 4 unfolds and surrounds the subject in a cylindrical shape. When collecting human image information, the traction mechanism 5 releases the lock on the background cloth 4. The position adjustment mechanism 2 adjusts the shooting angle of the camera 1 to collect multiple sets of human image information. The camera 1 sends the human image information to the industrial control computer for image information analysis. The industrial control computer extracts contour features from the human image information and builds a three-dimensional human body model to obtain human body data. The position adjustment mechanism 2 can adjust the shooting angle of the camera 1 and, together with the traction mechanism 5 and the storage mechanism 3, selects and arranges the background cloth 4 with a suitable color tone, reducing the difficulty for the industrial control computer to extract image features and improving measurement accuracy.

[0034] like Figure 3As shown, the position adjustment mechanism 2 includes an annular guide rail 21, a mounting plate 22 slidably disposed at the bottom end of the guide rail 21, a first motor 23 fixed to one side of the mounting plate 22, a gear 24 fixed to the output end of the first motor 23, and a toothed ring 25 located directly below the guide rail 21 and meshing with the gear 24. The annular guide rail 21 is connected to the top wall of the acquisition chamber 6 through a mounting frame. The toothed ring 25 is fixed to the mounting frame through a mounting tube. The camera 1 is disposed below the mounting plate 22. The camera 1 and the traction mechanism 5 are both mounted on the mounting plate 22. When adjusting the angle of the camera 1 and arranging the background cloth 4 through the traction mechanism 5, the first motor 23 drives the gear 24 to rotate. Through the meshing of the gear 24 and the toothed ring 25, the first motor 23 and the mounting plate 22 drive the camera 1 and the traction mechanism 5 to move on the annular guide rail 21.

[0035] Furthermore, the position adjustment mechanism 2 also includes a frame 26 fixed to the bottom of the mounting plate 22 and a lead screw motor 27 fixed to one end of the frame 26. The output shaft of the lead screw motor 27 is threadedly connected to a mounting base that is fixed to the camera 1. The mounting base is slidably connected to the frame 26. A limit rail is provided vertically on the frame 26. The mounting base is slidably connected to the frame 26 through the limit rail. The lead screw motor 27 drives the camera 1 to slide up and down along the frame 26 through the mounting base, thereby realizing the adjustment of the height of the camera 1.

[0036] Furthermore, such as Figure 7 As shown, the position adjustment mechanism 2 also includes two mounting plates 28 located on the inner and outer sides of the guide rail 21, respectively. The two mounting plates 28 are fixed to the top of the mounting plate 22. The opposite side of the two mounting plates 28 is provided with guide wheels 29 that fit against the guide rail 21. Both mounting plates 28 are arc-shaped and concentric with the annular guide rail 21. The cross-section of the annular guide rail 21 is I-shaped and consists of an annular top plate, an annular bottom plate, and an annular vertical plate fixed between the annular top plate and the annular bottom plate. Each mounting plate 28 is provided with at least two spindle-shaped guide wheels 29. The guide wheels 29 roll on the annular bottom plate of the guide rail 21. The guide wheels 29 on the two mounting plates 28 fit against the two sides of the annular vertical plate of the guide rail 21, respectively.

[0037] like Figure 5 and Figure 6As shown, the storage mechanism 3 includes a second motor 31, a top plate 32 fixed to the output end of the second motor 31, multiple winding frames 33 fixed to the bottom end of the top plate 32 and arranged circumferentially along the top plate 32, a third motor 34 fixed to the bottom end of the top plate 32 and corresponding to each winding frame 33, and a rotating shaft 35 fixed to the output end of the third motor 34 and rotatably connected to the winding frame 33. The fixed end of the second motor 31 is installed on the top wall of the acquisition chamber 6, and the rotating shaft 35 corresponds to each background cloth 4. Before acquiring human image information, the second motor 31 drives the top plate 32 to rotate, thereby rotating the winding frame 33 carrying the background cloth 4 with appropriate color difference to the side of the storage mechanism 3 near the position adjustment mechanism 2, so that the traction mechanism 5 locks the background cloth 4. After the human image information is acquired, the third motor 34 drives the rotating shaft 35 to rotate, and the background cloth 4 is re-stored inside the winding frame 33.

[0038] like Figure 5 , 8 As shown in Figure 9, the background cloth 4 includes a cloth body 41 wrapped around the outside of the rotating shaft 35 and fixed at one end to the rotating shaft 35, and a guide rod 42 fixed at the other end of the cloth body 41. A first electromagnet 43 is provided on the guide rod 42, and a first hanging wheel 44 is provided at the top of the guide rod 42. The traction mechanism 5 includes a vertical plate 51 fixed on the other side of the mounting plate 22, a limiting cover 52 fixed on the end of the vertical plate 51 away from the toothed ring 25, a second electromagnet 53 fixed inside the limiting cover 52, and an annular slide rail 54 concentric with the guide rail 21. The slide rail 54 is fixed on the mounting frame on the top wall of the collection chamber 6. The first electromagnet 43 on each background cloth 4 corresponds to the second electromagnet 53 on the traction mechanism 5. The cloth body 41 is made of a relatively hard material. Specifically, the cloth body 41 can be made of felt, or its material can be replaced with rubber. When the background cloth 4 is locked using organic polymer materials such as glue or plastic, the second electromagnet 53 is energized, and at the same time, the first electromagnet 43 on the background cloth 4, which is directly opposite the traction mechanism 5, is energized. Through the mutual attraction between the second electromagnet 53 and the first electromagnet 43, the guide rod 42 at the end of the cloth body 41 moves toward the vertical plate 51. When the first electromagnet 43 is embedded in the limiting cover 52, the background cloth 4 is locked. At this time, the first hanging wheel 44 enters the annular slide rail 54. The interior of the annular slide rail 54 is T-shaped. After the mounting plate 22 rotates around the annular guide rail 21 for one revolution, the first hanging wheel 44 also rolls along the slide rail 54 for one revolution. The guide rod 42 drives the cloth body 41 to rotate around the annular guide rail 21 for one revolution, thereby unfolding the cloth body 41. After the first electromagnet 43 and the second electromagnet 53 are de-energized, the traction mechanism 5 releases the locking of the background cloth 4.

[0039] like Figure 2As shown, the first electromagnet 43 is fixed to the outside of the movable frame 45, and a limiting plate 46 that is slidably connected to the movable frame 45 is fixed on the guide rod 42. A spring is provided between the limiting plate 46 and the movable frame 45. When the background cloth 4 is locked, the first electromagnet 43 and the second electromagnet 53 attract each other, and the movable frame 45 slides away from the limiting plate 46. The spring between the movable frame 45 and the limiting plate 46 is in a stretched state. The mounting plate 22 stops after rotating one revolution. At this time, the spring between the movable frame 45 and the limiting plate 46 plays a buffering role to avoid large stress at the connection between the cloth body 41 and the rotating shaft 35. When the background cloth 4 is unlocked, the first electromagnet 43 and the movable frame 45 are reset under the action of the spring.

[0040] like Figure 9 As shown, the limiting cover 52 has a flared opening at the end away from the vertical plate 51. The vertical plate 51 is connected to the frame 26 through a support plate. The support plate reinforces the vertical plate 51, improving the structural stability of the traction mechanism 5. The flared opening guides the first electromagnet 43, ensuring that the first electromagnet 43 can be smoothly embedded in the limiting cover 52.

[0041] like Figure 8 As shown, the slide rail 54 has a notch on the side near the storage mechanism 3. The notch has an inlet rail 55 with one end tangent to the slide rail 54. The other end of the inlet rail 55 is bent toward the storage mechanism 3. The top of the fabric body 41 is evenly provided with second hanging wheels 47. Both the first hanging wheel 44 and the second hanging wheel 47 are made of ferromagnetic metal. The top plate 32 is magnetic and can attract the first hanging wheel 44 and the second hanging wheel 47 when storing the background fabric 4. When the fabric body 41 is unfolded by the traction mechanism 5, the second hanging wheel 47 is guided by the inlet rail 55. The second hanging wheel 47 enters the annular slide rail 54 along the inlet rail 55 to shape the fabric body 41.

[0042] Furthermore, such as Figure 9As shown, a groove 36 is provided on the bottom side of the winding frame 33 near the guide rail 21. A limiting frame 37 for constraining the guide rod 42 is slidably connected inside the groove 36. A pressure sensor 38 is fixed at the end of the groove 36 away from the guide rod 42. The pressure sensor 38 is spring-connected to the limiting frame 37. A bottom plate 39 is provided directly below the top plate 32. A support shaft is provided at the center of the bottom plate 39 and is rotatably connected to the bottom wall of the collection chamber 6. Multiple directional wheels are also evenly arranged around the circumference of the bottom plate 39, which are in contact with the bottom wall of the collection chamber 6. The hinge axes of the multiple directional wheels all point to the support shaft. The support shaft and the multiple directional wheels provide support for the storage mechanism 3 and reduce the axial force on the second motor 31. Multiple winding frames 33 are evenly fixed around the bottom plate 39. When storing the background cloth 4, the third motor 34 drives the rotating shaft 35 to rotate, winding the cloth body 41 onto the rotating shaft. On the outside of 35, the limiting frame 37 consists of a slider located inside the slide groove 36 and two limiting rods fixed to the top of the slider. The two limiting rods are located on both sides of the fabric body 41, and the distance between the two limiting rods is less than the thickness of the guide rod 42. When the background fabric 4 is stored, the limiting frame 37 intercepts the guide rod 42. When the fabric body 41 is finished winding, the guide rod 42 pushes the limiting frame 37 to slide in the slide groove 36. The limiting frame 37 provides pressure to the pressure sensor 38 through the spring. When the pressure sensor 38 detects that the pressure reaches the threshold, the third motor 34 is turned off to prevent the fabric body 41 from continuing to rotate around the axis of the winding frame 33 after winding. This ensures that the guide rod 42 is in a position close to the edge of the base plate 39 after storage, and ensures that the magnetic force between the first electromagnet 43 and the second electromagnet 53 is sufficient each time the background fabric 4 is locked.

[0043] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
