[0030] Example 1

[0031] A foot-shaped foot pressure integrated machine includes a base 10. A rectangular mounting groove 101 is formed on the upper surface of the base 10. The mounting groove 101 is centrally located. A back plate 4 is provided at the bottom of the mounting groove 101. A pressure sensing piece 5 is disposed on the upper surface of the back plate 4. The back plate 4 is used to horizontally support the pressure sensing piece 5. A felt layer 6 is provided on the upper surface of the pressure sensing piece 5. A cover film 7 is provided on the upper surface of the felt layer 6. The pressure sensing piece 5 is used to sense the pressure of a person standing on it. The felt layer 6 is used to increase the sensing sensitivity of the pressure sensing piece 5. The cover film 7 is used to prevent dust and protect the felt layer 6. A footprint area is marked on the cover film 7 (not shown in the figure).

[0032] The upper surface of the base 10 is also provided with four mounting holes 102. The four mounting holes 102 are evenly distributed around the circumference of the mounting groove 101 and are located at the four corners of the mounting groove 101. The camera bracket 20 is composed of a front housing 201 and a rear housing 202. The front housing 201 and the rear housing 202 are connected by bolts. The scanning camera 9 is mounted on the front housing 201. The camera bracket 20 is detachably installed in the mounting hole 102. In this embodiment, a positioning protrusion 1021 is provided in the mounting hole 102. A locking groove 2011 is provided at the bottom of the front housing 201. The locking groove 2011 is engaged with the positioning protrusion 1021. The locking groove 2011 and the positioning protrusion 1021 are connected by bolts. When installing the camera bracket 20, first align the slot 2011 of the front housing 201 with the positioning protrusion 1021, then install the front housing 201 on the base 10 with bolts, and then connect the rear housing 202 to the front housing 201 with bolts.

[0033] A metal cover plate 30 is provided on the upper surface of the base 10. The metal cover plate 30 has positioning holes 302 corresponding to the mounting holes 102 and positioning grooves 301 corresponding to the mounting grooves 101. The upper surface of the metal cover plate 30 and the upper surface of the cover film 7 are on the same horizontal plane. A data acquisition and analysis module 60 is also provided inside the base 10. A hinge plate is provided on one side of the base 10, and a touch panel (not shown in the figure) is snapped onto the hinge plate. The data acquisition and analysis module 60 has a switch button and a connection port. The switch button is used to start the module, and the connection port is used to connect to a control panel. The control panel is used to control the operation of the data acquisition and analysis module 60. The data collected by the scanning camera 9 (foot shape data) and the foot pressure data collected by the pressure sensor 5 are transmitted to the data acquisition and analysis module 60. The data acquisition and analysis module 60 outputs the relevant data. An anti-slip pad (not shown in the figure) is provided at the bottom of the base 10.

[0034] Working Principle: Before foot pressure and foot shape measurements, users first use a calibration board with a black and white grid to determine the relative position of the scanning camera. During the measurement, users remove their shoes and socks, roll up their trousers to expose their ankles, and stand at the footprint of the foot pressure and shape measuring machine, remaining stable and looking straight ahead. Then, the measurement personnel click the "Start Detection" button on the touch panel. The data acquisition and analysis module 60 receives the data uploaded by the foot pressure and shape measuring machine, analyzes the data, and generates a test report. The report includes foot type, foot characteristics, foot shape influences, suitable footwear, hallux valgus angle, heel eversion, foot shape data, arch data, static foot division parameters, arch analysis, etc. Based on the obtained data, shoes / boots, insoles can be customized, or appropriate corrective training can be provided based on the measurement data.

[0035] It should be noted that the data acquisition and analysis module 60 is not the core innovation of this application. The data acquisition and analysis module 60 is adapted to a data chip, and the data chip has embedded software for implementing the analysis function in the data acquisition and analysis template of this application, so as to realize the analysis of the acquired data. Therefore, this application will not elaborate on it further.

[0036] Workflow of pressure sensor 5 and data acquisition and analysis module 60: Foot pressure data → Import into insole / shoe customization system software → Add foot shape parameters of the person whose foot pressure data belongs (including but not limited to: foot length, foot width, arch height, etc.) Import the foot model of the person whose foot pressure data belongs obtained by scanning camera 9 → Based on foot shape data → Obtain the structure of the insole / shoe that best fits the foot shape (e.g., length, width, thickness) → Based on foot pressure data → Adjust the material hardness or height of different areas of the insole (e.g., the heel area bears a lot of pressure, so in order to reduce the stress in the area, the material of the heel area of ​​the insole will be adjusted to have a lower hardness).

[0037] Scanning camera 9 workflow: Four scanning cameras 9 acquire foot shape photos from various directions → Image stitching generates a 3D foot model → (If movement occurs during the acquisition process, the stitching will fail and the test will be invalid) → Foot shape parameters are calculated based on spatial calibration parameters.

[0038] For example, when this foot-shaped foot pressure integrated machine is used in shoe stores for shoe selection: a person stands on the instrument → relevant data is collected → relevant software analyzes the collected data → outputs a shoe-making plan → the factory makes shoes according to the plan.

[0039] Example 2

[0040] To more accurately measure foot shapes of different heights and sizes, a foot pressure integrated machine is proposed, including a base 10. A rectangular mounting groove 101 is formed on the upper surface of the base 10, and the mounting groove 101 is centrally located. A back plate 4 is provided at the bottom of the mounting groove 101. A pressure sensing piece 5 is disposed on the upper surface of the back plate 4. The back plate 4 is used to horizontally support the pressure sensing piece 5. A felt layer 6 is provided on the upper surface of the pressure sensing piece 5, and a cover film 7 is provided on the upper surface of the felt layer 6. The pressure sensing piece 5 is used to sense the pressure of a person standing on it. The felt layer 6 is used to increase the sensing sensitivity of the pressure sensing piece 5. The cover film 7 is used to prevent dust and protect the felt layer 6. The cover film 7 is marked with a footprint area (not shown in the figure).

[0041] The base 10 is equipped with a data acquisition and analysis module 60 (the connection method is the same as in Embodiment 1, but not shown in the accompanying drawings of this embodiment). The data acquisition and analysis module 60 is equipped with a switch button and a connection port. The data acquisition and analysis module 60 is connected to the pressure sensor 5. The switch button is used to start the module, and the connection port is used to connect to the control panel that controls the operation of the data acquisition and analysis module 60 and the servo motor 403.

[0042] A metal cover plate 30 is provided on the upper surface of the base 10. A rectangular positioning groove 301 corresponding to the mounting groove 101 is formed on the metal cover plate 30. Multiple sliding holes 303 are formed around the periphery of the positioning groove 301. In this embodiment, four sliding holes 303 are provided, arranged along the edge of the positioning groove 301. A mounting base 8 is slidably disposed within each sliding hole 303. A camera bracket 20 is detachably disposed within the mounting base 8. In this embodiment, the mounting base 8 has... The camera bracket 20 has mounting holes 102, and a positioning protrusion 1021 is provided in the mounting holes 102. The camera bracket 20 consists of a front housing 201 and a rear housing 202, which are connected by bolts. The scanning camera 9 is mounted on the front housing 201. The bottom of the front housing 201 is provided with a locking groove 2011, which engages with the positioning protrusion 1021. The locking groove 2011 and the positioning protrusion 1021 are connected by bolts. The base 10 is provided with an adjustment mechanism 40, which is used to adjust the rotation angle and horizontal height of the mounting base 8.

[0043] The adjustment mechanism 40 includes a synchronous belt 401, synchronous pulleys 402, a servo motor 403, a sliding shaft 404, a track 405, and a deflection assembly 50. The four synchronous pulleys 402 are rotatably mounted within the base 10. The synchronous belt 401 is engaged with the synchronous pulleys 402. Under the constraint of the four synchronous pulleys 402, the sides of the rectangle formed by the synchronous belt 401 correspond one-to-one with the sliding holes 303. The servo motor 403 is fixedly mounted within the base 10. One of the synchronous pulleys 402 is coaxially mounted on the output shaft of the servo motor 403. There are four sliding shafts 404, and each sliding hole 303 contains one sliding shaft 404. The upper end of the sliding shaft 404 is connected to the mounting base 8. The bottom center of the mounting base 8 is provided with a polygonal prism. The upper end of the sliding shaft 404 is provided with a polygonal groove 4041 that matches the polygonal prism. The polygonal prism and the polygonal groove 4041 are connected by bolts.

[0044] A connecting plate 408 is provided on the outer side of the synchronous belt 401. The sliding shaft 404 is movably mounted on the connecting plate 408. Four tracks 405 are arranged along the edge of the synchronous belt 401. A slider 406 is rotatably mounted on the lower end of the sliding shaft 404. The slider 406 slides along the track 405. The bottom surface of the track 405 is inclined. The lower surface of the slider 406 is adapted to the bottom surface of the track 405. A spring 407 is sleeved on the sliding shaft 404. The spring 407 is located between the connecting plate 408 and the slider 406. The deflection assembly 50 is used to drive the sliding shaft 404 to rotate.

[0045] The deflection assembly 50 includes a rack 501 and a gear 502. The gear 502 is coaxially sleeved on the sliding shaft 404. The spring 407 is located between the gear 502 and the connecting plate 408. The rack 501 is arranged along the track 405.

[0046] During measurement, the servo motor 403 drives the synchronous pulley 402 to rotate, and the synchronous belt 401 rotates under the action of the synchronous pulley 402, driving the connecting plate 408 to rotate. The connecting plate 408 drives the sliding shaft 404 to slide along the track 405, thereby driving the mounting base 8 and the camera bracket 20 to move along the sliding hole 303. At the same time, the gear 502 rotates under the drive of the rack 501, driving the sliding shaft 404 to rotate as a whole, so that the camera bracket 20 rotates while moving along the sliding hole 303, ensuring that the focal length of the scanning camera 9 mounted on the camera bracket 20 always falls on the measurement position. Simultaneously, as the sliding shaft 404 slides, the slider 406 located at the lower end of the sliding shaft 404 slides along the track 405. Since the bottom surface of the track 405 is inclined, the slider 406 moves in the vertical direction, causing the mounting base 8 and the camera bracket 20 to move up and down, thus accommodating different foot sizes.

[0047] Working principle: When taking foot pressure and foot shape measurements, the user first removes shoes and socks, rolls up trouser legs to expose the ankles, stands at the footprint of the foot pressure and shape measuring machine, remains stable, and looks straight ahead. Then, the measuring person controls the servo motor 403 through the touch panel to adjust the position of the camera bracket 20 so that the height of the camera bracket 20 is adjusted according to the height of the person being measured. Clicking the start detection button on the touch panel starts the foot pressure and shape measuring machine from working. After the operation is completed, the foot pressure and shape measuring machine will display the corresponding results, such as foot type, foot characteristics, foot shape influence, suitable shoes, hallux valgus angle, heel eversion, foot data, arch data, static foot division parameters, arch analysis data, etc.
