Description

Technical Field

[0001] This invention belongs to the field of posture capture technology, specifically a multi-angle dynamic posture capture device for sports events. Background Technology

[0002] The multi-angle dynamic posture capture device for sports events is designed to capture high-speed, complex movements of athletes in a comprehensive, high-precision, and quantifiable manner through multi-camera, high-speed, and synchronous image capture. It is used in four core scenarios: scientific training, event analysis, broadcasting and recording, and injury prevention and scientific research. The device synthesizes data from multiple cameras simultaneously to calculate precise data such as joint angles, movement trajectories, speeds, and force exertion sequences. It also provides quantitative analysis of running posture, shooting release, jumping force, and stroke angles to identify technical flaws.

[0003] A Chinese patent with publication number CN120769170A discloses a posture capture device specifically for sports events. The device includes a housing with a support plate inside. A buffer mechanism is mounted on the support plate, and a camera for posture capture is mounted on top of the buffer mechanism. An adjustment mechanism for adjusting the position of the support plate is located inside the housing, as well as a protective mechanism for protecting the camera. A frame is symmetrically arranged at the bottom of the support plate, and a compression mechanism for compressing air is located inside the frame. This posture capture device for sports events, through its threaded rod and support plate, facilitates the storage, protection, and deployment of the camera. When storing the camera, a servo motor moves the support plate smoothly, allowing the camera to move downwards and into the housing, thus achieving convenient storage and protection and improving the protective capabilities of the posture capture device for sports events.

[0004] Current multi-angle dynamic posture capture devices for sports events have limitations when used to capture athletes' movements at the event site. These limitations include poor flexibility in adjusting the capture position, inability to accurately capture close-up shots of athletes' specific movements, susceptibility to external environmental factors during operation, difficulty in achieving layered capture of athletes at different heights, and limited applicability.

[0005] Therefore, the present invention provides a multi-angle dynamic posture capture device for sports events. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of inconvenient adjustment of the capture position, this invention proposes a multi-angle dynamic posture capture device for sports events.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a multi-angle dynamic posture capture device for sports events, including a column, the column being hollow, a support frame being provided at the bottom of the column, a support rod being inserted inside the column, an adjustment mechanism for adjusting the position of the support rod being provided inside the column, a load-bearing frame being fixedly connected to the top of the support rod, three sets of support columns being arrayed on the load-bearing frame, a capture camera being fixedly installed at the top of the support column via a mounting plate, and a control box being fixedly installed on the back of the column; The front of the load-bearing frame is fixedly provided with a strip frame corresponding to the support column. A first cylinder is inserted inside the strip frame. A second cylinder is inserted inside the first cylinder. A first plane mirror is fixedly installed inside the first cylinder. A second plane mirror is fixedly installed inside the second cylinder. The strip frame is equipped with a drive mechanism for adjusting the position of the second cylinder, the support column is equipped with a support mechanism for supporting the first cylinder, and the strip frame is equipped with a compression mechanism.

[0008] By adopting the above scheme, when using a multi-angle dynamic posture capture device to capture athletes' postures in sports events, the support frame, column, support rod, load-bearing frame, and support column work together to support the capture camera, ensuring the camera is aimed at the event location. By controlling the capture camera's operation, the athlete's full-body posture can be captured. Furthermore, through the servo motor and the support column, the camera's angle can be adjusted, facilitating multi-angle capture of athletes' postures. A protective cover is used to seal and protect the ends of the first and second cylinders. The protective cover is removable, washable, and replaceable. The protective cover is covered with a transparent optical material. When capturing athletes from a low angle, if the optical material on the protective cover becomes blurry... The protective cover can be replaced beforehand. After adjusting the capture camera to a predetermined angle, the position of the first cylinder can be adjusted by the movement of the support mechanism so that one end of the first cylinder coincides with the lens of the capture camera. The light is refracted by the first and second plane mirrors, and the capture camera can capture the athlete's posture and accurately capture close-up shots of parts of the athlete's body. The captured image will not be obstructed or interfered with by other parts of the athlete's body. By coordinating multiple sets of capture cameras, it is possible to capture the athlete's overall movement posture comprehensively, or to capture close-up shots of specific parts of the athlete's body. The position of the second cylinder can be adjusted by the movement of the drive mechanism, and the second cylinder can be adjusted to different positions to facilitate capturing different parts of the athlete.

[0009] Preferably, the support frame is provided with wheels, and the support frame has a cavity inside; The adjustment mechanism includes an adjustment screw, a drive motor, and a reducer. The outer surface of the adjustment screw is threadedly connected to the inside of the support rod. The drive motor is fixed inside the support frame. The reducer is fixedly installed inside the cavity, and the output end of the drive motor is fixedly connected to the input end of the reducer. The output end of the reducer is fixedly connected to one end of the adjustment screw.

[0010] By adopting the above solution, the support frame is easy to move with its wheels, which facilitates the placement of the capture camera. The support frame provides installation space for the reducer through its cavity. Controlling the drive motor will drive the reducer to move. When the reducer moves, it will drive the adjusting screw to rotate. When the adjusting screw rotates, it will adjust the height of the load-bearing frame. When the load-bearing frame moves, the height of the capture camera can be adjusted through the support column, thereby improving flexibility and making it easy to adjust the installation height according to the site.

[0011] Preferably, a servo motor corresponding to the support column is fixedly installed on the load-bearing frame, and the output end of the servo motor is fixedly connected to the end of the corresponding support column.

[0012] By adopting the above solution, the servo motor will drive the support column to rotate, which in turn will drive the camera to rotate, allowing the capture angle to be adjusted.

[0013] Preferably, the support mechanism includes a sliding cylinder, an electromagnet, an electric push rod, a through groove, a support block, and a connecting block. The sliding cylinder is sleeved on the support column, the electromagnet is embedded in the sliding cylinder, the support column is made of magnetic material and is hollow, the electric push rod is fixed inside the support column, the through groove is provided on the support column, the support block passes through the through groove and the telescopic end of the electric push rod is fixedly connected to the support block, and the connecting block is fixed on the first cylinder and passes through the strip frame and is fixedly connected to the sliding cylinder.

[0014] By adopting the above scheme, controlling the electric push rod will adjust the position of the support block. When the support block moves in the through groove, it will drive the sliding cylinder to move. When the sliding cylinder moves, it will drive the first cylinder to move through the connecting block. After the first cylinder moves to the predetermined position, the electromagnet will be controlled to generate a strong magnet. In conjunction with the support column, the position of the sliding cylinder can be positioned, and then the position of the first cylinder can be positioned. By adjusting the position of the first cylinder, it is possible to capture the athlete's full-body posture or close-up details.

[0015] Preferably, the drive mechanism includes a load-bearing block, a threaded cylinder, a power motor, and a threaded rod. The load-bearing block is fixed on the second cylinder, the threaded cylinder is fixed on the load-bearing block, the threaded rod is threadedly connected inside the threaded cylinder, and the power motor is fixed inside the strip frame, with the output end of the power motor fixedly connected to one end of the threaded rod.

[0016] By adopting the above scheme, controlling the power motor will drive the threaded rod to rotate. When the threaded rod rotates, it will adjust the position of the threaded cylinder. The movement of the threaded cylinder will drive the position of the second cylinder to be adjusted through the load-bearing block. In turn, by adjusting the position of the second cylinder, it is convenient to capture the athlete in different positions.

[0017] Preferably, a guide block is fixedly provided on the side of the threaded cylinder, and a guide rod is passed through the guide block, with the end of the guide rod fixedly connected to the inside of the strip frame.

[0018] By adopting the above scheme, the threaded cylinder will move along with the guide block. When the guide block moves, it will guide the threaded cylinder through the guide rod, so that the threaded cylinder moves smoothly.

[0019] Preferably, the compression mechanism includes a strip plate, a compression block, a compression groove, a one-way intake valve, and a one-way exhaust valve. The strip plate is fixed to the top of the guide block, the compression groove is fixed inside the strip frame and located on one side of the threaded rod, the compression block is disposed inside the compression groove, and the top of the strip plate is fixedly connected to the compression block. The one-way intake valve is disposed on the compression groove, and the one-way exhaust valve is fixed on the compression groove.

[0020] By adopting the above scheme, when the guide block moves, it will drive the strip plate to move synchronously. When the guide block moves upward, it will drive the compression block to move. The compression block will compress the air inside the compression tank. The compressed air will enter the one-way exhaust valve and be discharged through the one-way exhaust valve. When the guide block is reset and the compression block is reset by the strip plate, the outside air can be drawn through the one-way intake valve.

[0021] Preferably, the first cylinder is provided with a first exhaust head, which is located on one side of the first plane mirror. The second cylinder is provided with a second exhaust head, and the output end of the one-way exhaust valve is connected to the first exhaust head and the second exhaust head respectively through a telescopic hose. The ends of the first cylinder and the second cylinder are both connected with protective covers.

[0022] By adopting the above scheme, when the air inside the compression tank is compressed, the compressed air flows into the one-way exhaust valve and then through the telescopic hose, the compressed air flows into the No. 1 exhaust head and the No. 2 exhaust head. Through the No. 1 exhaust head and the No. 2 exhaust head, the airflow will flow to the corresponding No. 1 plane mirror and the No. 2 plane mirror, thereby cleaning the No. 1 plane mirror and the No. 2 plane mirror, which can effectively prevent the adsorption of impurities on the No. 1 plane mirror and the No. 2 plane mirror from affecting the capture effect.

[0023] Preferably, a protective shell is fixedly provided on the side of the load-bearing block, and the protective shell is rectangular in shape, with a protective mirror fixedly provided inside the protective shell.

[0024] By adopting the above solution, the load-bearing block provides installation space for the protective shell, and the protective shell supports the installation of the protective goggles.

[0025] Preferably, a laser emitting component is fixedly installed inside the protective shell, and the laser emitting component is located on one side of the protective mirror. A control button is provided on the protective shell, and the control button is electrically connected to the laser emitting component.

[0026] By adopting the above scheme, the laser emitting component can be controlled to work via the control button. The laser emitting component generates a laser beam, which shines horizontally forward after passing through the protective lens. The laser beam is arranged parallel to the bottom of the second cylinder. When preset and debugging the capture position, the laser beam can be used to quickly calibrate the horizontal position, effectively improving the accuracy of the capture positioning. The working status of the laser emitting component can also be controlled by the controller inside the control box, and can be flexibly adjusted according to the needs.

[0027] The beneficial effects of this invention are as follows: 1. The multi-angle dynamic posture capture device for sports events described in this invention, by setting up a first plane mirror and a second plane mirror, facilitates close-up capture of athletes' partial postures. During operation, the electric push rod can adjust the position of the support block, and through the transmission of the connecting block, it drives the first cylinder to move. Once the first cylinder is adjusted to the preset position, flexible capture of the athlete's full-body posture or partial close-ups can be achieved. The first and second plane mirrors work together to form a periscope optical path, which, in conjunction with the capture camera, completes the acquisition and capture of the athlete's movement posture. It can accurately capture close-up shots of parts of the athlete's body, effectively avoiding image obstruction and visual interference from other body parts. The local imaging is clear and the capture accuracy is high. Simultaneously, multiple capture cameras are deployed collaboratively, allowing for both all-around capture of the athlete's overall movement posture and fixed-point close-up capture of individual body parts. The use of plane mirrors to achieve optical path deflection allows the main body of the capture camera to be kept away from the movement area, with only the front-end viewing area close to the track and movement range. This eliminates the need to occupy the sports field and does not affect the athlete's normal competition and training, effectively avoiding safety hazards associated with equipment deployment.

[0028] 2. The multi-angle dynamic posture capture device for sports events described in this invention, by setting a threaded cylinder and a load-bearing block, allows for flexible adjustment of the installation position of the second cylinder, facilitating layered capture of athletes at different heights. The motor drives the threaded rod to rotate, and the rotation of the threaded rod adjusts the position of the threaded cylinder. The threaded cylinder, via the load-bearing block, synchronously moves the second cylinder, allowing it to be adjusted to different heights to accommodate capture needs of different body parts of the athlete. The framing end can be flexibly set at any horizontal height, such as ankle, knee, waist, or shoulder, using a level view. The camera captures images from a single perspective, without perspective distortion, and can realistically reproduce athletes' body movements and postures, providing accurate data for subsequent motion analysis and technical correction. When deployed with multiple sets of capture cameras, it can capture the athlete's overall posture from all angles, and can also capture independent close-up shots of different body areas such as the lower limbs, torso, and upper limbs, achieving multi-dimensional and comprehensive information acquisition of movement postures. The overall structure is simple, easy to install and debug, and has low deployment costs. It can capture natural and realistic movement states and effectively improve the data effectiveness of sports event posture capture.

[0029] 3. The multi-angle dynamic posture capture device for sports events described in this invention, by setting a compression groove, can automatically clean impurities adsorbed on the surface of the plane mirror, effectively ensuring the capture imaging effect. When the guide block moves, it can drive the strip plate to move synchronously. While the guide block moves upward, it drives the compression block to move. The compression block squeezes and compresses the air inside the compression groove. The compressed airflow enters the one-way exhaust valve, and the one-way exhaust valve completes the airflow transportation and discharge. When the air inside the compression groove is compressed, the high-pressure airflow is transported to the telescopic hose through the one-way exhaust valve, and then introduced into the first exhaust head and the second exhaust head respectively through the telescopic hose. The first exhaust head and the second exhaust head output directional wind force to blow and sweep the surface of the first plane mirror and the second plane mirror, realizing automatic cleaning treatment of the mirror surface. It can remove dust, debris and other impurities attached to the mirror surface in time, effectively avoiding the attachment of impurities to block the light path and interfere with the image quality, and preventing the capture accuracy and effect of the athlete's posture due to mirror surface contamination.

[0030] 4. The multi-angle dynamic posture capture device for sports events described in this invention generates laser rays by emitting laser emitting components. After passing through the protective mirror, the laser rays are projected horizontally forward. The laser rays are arranged parallel to the bottom end of the second cylinder. When preset and adjusting the capture position, the horizontal position can be quickly calibrated with the help of the laser rays, which effectively improves the accuracy of capture positioning.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 11As shown in the embodiment of the present invention, a multi-angle dynamic posture capture device for sports events includes a column 1, which is hollow. A support frame 2 is provided at the bottom of the column 1, and a support rod 5 passes through the inside of the column 1. An adjustment mechanism for adjusting the position of the support rod 5 is provided inside the column 1. A load-bearing frame 9 is fixedly connected to the top of the support rod 5. Three sets of support columns 10 are arranged in an array on the load-bearing frame 9. A capture camera 11 is fixedly mounted on the top of the support column 10 through a mounting plate. A control box 24 is fixedly mounted on the back of the column 1. A strip frame 14 corresponding to the support column 10 is fixedly installed on the front of the frame 9. A first cylinder 15 is inserted inside the strip frame 14. A second cylinder 16 is inserted inside the first cylinder 15. A first plane mirror 17 is fixedly installed inside the first cylinder 15. A second plane mirror 18 is fixedly installed inside the second cylinder 16. A drive mechanism for adjusting the position of the second cylinder 16 is installed inside the strip frame 14. A support mechanism for supporting the first cylinder 15 is installed on the support column 10. A compression mechanism is installed inside the strip frame 14. The control box 24 is equipped with a controller and power supply components (existing technology), which are electrically connected to the electronic equipment on the sports event multi-angle dynamic posture capture device. It can remotely control the operation of the electronic equipment. The sports event multi-angle dynamic posture capture device is equipped with a bellows corresponding to the adjusting screw 6 and the threaded rod 23. The bellows is retractable and can shield and protect the adjusting screw 6 and the threaded rod 23 to prevent external corrosion. When using a multi-angle dynamic posture capture device to capture the posture of athletes in sports events, the support frame 2, column 1, support rod 5, load-bearing frame 9 and support column 10 work together to support the capture camera 11, so that the capture camera 11 is aimed at the event location. By controlling the operation of the capture camera 11, the full-body posture of the athlete can be captured. Furthermore, by working through the servo motor 13 and cooperating with the support column 10, the angle of the capture camera 11 can be adjusted, thus facilitating the capture and processing of the athlete's posture from multiple angles. Protective cover 38 is used to seal and protect the ends of cylinder 15 and cylinder 16. Protective cover 38 is removable, washable, and replaceable. It is covered with a transparent optical material. If the optical material on protective cover 38 is blurry when capturing athletes from a low angle, it can be replaced beforehand. After adjusting the camera 11 to a predetermined angle, the position of cylinder 15 can be adjusted via the movement of the support mechanism, aligning one end of cylinder 15 with the lens of camera 11. This is achieved through the movement of plane mirror 17 and plane mirror 16. 8. With the help of refracted light, the capture camera 11 can capture the athlete's posture and accurately capture close-up shots of parts of the athlete's body. The captured image will not be obstructed or interfered with by other parts of the athlete's body. With the cooperation of multiple capture cameras 11, it can capture the athlete's overall movement posture in a comprehensive manner, or capture close-up shots of each part of the athlete's body at a fixed point. The position of the second cylinder 16 can be adjusted by the movement of the drive mechanism. The second cylinder 16 can be adjusted to different positions to facilitate capturing the athlete from different positions. By setting up a periscope optical path using plane mirror 17 and plane mirror 18, it is possible to capture pinpoint close-up shots of specific parts of the athlete's body. This effectively avoids image obstruction and visual interference from other parts of the athlete's body, resulting in clear local imaging and precise capture. Furthermore, by utilizing the plane mirrors to achieve optical path deflection, the main body of the camera 11 can be kept away from the sports area, with only the front-end framing part close to the track or activity area. This does not occupy the sports field, does not affect the athlete's normal competition and training, and eliminates safety hazards associated with equipment deployment. Simultaneously, the framing end can be set at any horizontal height, such as ankle, knee, waist, or shoulder, for optimal viewing. The camera captures images from different angles without perspective distortion, realistically reproducing body movements and postures, facilitating subsequent motion analysis and technical correction. When deployed in conjunction with multiple sets of capture cameras 11, it can capture the athlete's overall posture from all angles, as well as capture individual close-up shots of different body parts such as the lower limbs, torso, and upper limbs. This enables multi-dimensional and comprehensive posture information acquisition. The camera is simple in structure, easy to install and debug, and has low deployment costs. It can also be installed discreetly, making it less likely to distract the athlete. It can capture natural and realistic movement states, greatly improving the effectiveness of motion posture capture data. When the drive mechanism moves, it drives the compression mechanism to compress air. Through the cooperation of exhaust head 36 and exhaust head 37, the compressed air can flow to the surfaces of plane mirror 17 and plane mirror 18, which can clean plane mirror 17 and plane mirror 18, ensuring the effect of capturing close-up poses of athletes.

[0036] Furthermore, the support frame 2 is provided with a traveling wheel 4, and the support frame 2 is provided with a cavity 3. The adjustment mechanism includes an adjustment screw 6, a drive motor 7 and a reducer 8. The outer surface of the adjustment screw 6 is threadedly connected to the inside of the support rod 5. The drive motor 7 is fixed inside the support frame 2, and the reducer 8 is fixedly installed inside the cavity 3. The output end of the drive motor 7 is fixedly connected to the input end of the reducer 8, and the output end of the reducer 8 is fixedly connected to one end of the adjustment screw 6. The support frame 2 is easily moved by the wheels 4, which facilitates the placement of the capture camera 11. The support frame 2 provides installation space for the reducer 8 through the cavity 3. The control of the drive motor 7 will drive the reducer 8 to move. When the reducer 8 moves, it will drive the adjusting screw 6 to rotate. When the adjusting screw 6 rotates, it will adjust the height of the load-bearing frame 9. When the load-bearing frame 9 moves, the height of the capture camera 11 can be adjusted through the support column 10, thereby improving flexibility and making it easy to adjust the installation height according to the site.

[0037] Furthermore, a servo motor 13 corresponding to the support column 10 is fixedly installed on the load-bearing frame 9, and the output end of the servo motor 13 is fixedly connected to the end of the corresponding support column 10. When the servo motor 13 is working, it drives the support column 10 to rotate, which in turn drives the capture camera 11 to rotate, allowing the capture angle to be adjusted.

[0038] Furthermore, the support mechanism includes a sliding cylinder 12, an electromagnet 25, an electric push rod 26, a through groove 27, a support block 28, and a connecting block 29.

The connecting block 29 is fixed on the first cylinder 15, and the connecting block 29 passes through the strip frame 14 and is fixedly connected to the sliding cylinder 12. When adjusting the position of the first cylinder 15, the operation of the electric push rod 26 will adjust the position of the support block 28. When the support block 28 moves in the through groove 27, it will drive the sliding cylinder 12 to move. When the sliding cylinder 12 moves, it will drive the first cylinder 15 to move through the connecting block 29. After the first cylinder 15 moves to the predetermined position, the operation of the electromagnet 25 will generate a strong magnet, which will cooperate with the support column 10 to position the sliding cylinder 12, and then position the first cylinder 15. Adjusting the position of the first cylinder 15 can realize the capture of the athlete's full-body posture or close-up of a part.

[0039] Furthermore, the drive mechanism includes a load-bearing block 19, a threaded cylinder 20, a power motor 22, and a threaded rod 23. The load-bearing block 19 is fixed on the second cylinder 16, the threaded cylinder 20 is fixed on the load-bearing block 19, the threaded rod 23 is threadedly connected inside the threaded cylinder 20, and the power motor 22 is fixed inside the strip frame 14, and the output end of the power motor 22 is fixedly connected to one end of the threaded rod 23. The operation of the control motor 22 will drive the threaded rod 23 to rotate. When the threaded rod 23 rotates, it will adjust the position of the threaded cylinder 20. The movement of the threaded cylinder 20 will drive the position of the second cylinder 16 to be adjusted through the load block 19. In turn, by adjusting the position of the second cylinder 16, it is convenient to capture the athlete in different positions. The outer surface of cylinder 16 is fitted to the inside of cylinder 15. Cylinder 15 and cylinder 16 are concentric. The first plane mirror 17 and the second plane mirror 18 facilitate the refraction of light to capture close-up shots of the athletes.

[0040] Furthermore, a guide block 30 is fixedly provided on the side of the threaded cylinder 20, and a guide rod 21 is passed through the guide block 30, with the end of the guide rod 21 fixedly connected to the inside of the strip frame 14. When the threaded cylinder 20 moves, it will drive the guide block 30 to move. When the guide block 30 moves, it will guide the threaded cylinder 20 through the guide rod 21, so that the threaded cylinder 20 moves smoothly.

[0041] Furthermore, the compression mechanism includes a strip plate 31, a compression block 32, a compression groove 33, a one-way intake valve 34, and a one-way exhaust valve 35. The strip plate 31 is fixed to the top of the guide block 30, the compression groove 33 is fixed inside the strip frame 14, and the compression groove 33 is located on one side of the threaded rod 23. The compression block 32 is disposed inside the compression groove 33, and the top of the strip plate 31 is fixedly connected to the compression block 32. The one-way intake valve 34 is disposed on the compression groove 33, and the one-way exhaust valve 35 is fixed on the compression groove 33. When the guide block 30 moves, it will drive the strip plate 31 to move synchronously. When the guide block 30 moves upward, it will drive the compression block 32 to move. The compression block 32 will compress the air inside the compression groove 33. The compressed air will enter the one-way exhaust valve 35 and be discharged through the one-way exhaust valve 35. When the guide block 30 is reset and the compression block 32 is reset by the strip plate 31, the outside air can be drawn through the one-way air intake valve 34. The one-way intake valve 34 is covered with a filter screen, which can effectively prevent external impurities from entering the compression tank 33.

[0042] Furthermore, a first exhaust head 36 is provided on the first cylinder 15, and the first exhaust head 36 is located on one side of the first plane mirror 17. A second exhaust head 37 is provided on the second cylinder 16, and the output end of the one-way exhaust valve 35 is connected to the first exhaust head 36 and the second exhaust head 37 respectively through a telescopic hose. Protective covers 38 are connected to the ends of the first cylinder 15 and the second cylinder 16. When the air inside the compression tank 33 is compressed, the compressed air flows into the one-way exhaust valve 35 and then through the telescopic hose, the compressed air flows into the first exhaust head 36 and the second exhaust head 37. Through the first exhaust head 36 and the second exhaust head 37, the airflow is directed to the corresponding surfaces of the first plane mirror 17 and the second plane mirror 18, thereby cleaning the first plane mirror 17 and the second plane mirror 18. This effectively prevents impurities from adsorbing on the first plane mirror 17 and the second plane mirror 18 and affecting the capture effect. The removed impurities can be temporarily stored in the first cylinder 15 and the second cylinder 16. The impurities can be removed periodically. The first plane mirror 17 and the second plane mirror 18 are both installed at a 45-degree angle.

[0043] Furthermore, a protective shell 39 is fixedly installed on the side of the load-bearing block 19, and the protective shell 39 is rectangular in shape. A protective mirror 40 is fixedly installed inside the protective shell 39. The load-bearing block 19 provides installation space for the protective shell 39, and the protective shell 39 supports the installation of the protective mirror 40.

[0044] Furthermore, a laser emitting component 41 is fixedly installed inside the protective shell 39, and the laser emitting component 41 is located on one side of the protective mirror 40. A control button 42 is provided on the protective shell 39, and the control button 42 is electrically connected to the laser emitting component 41. The laser emitting component 41 can be controlled by the control button 42. The laser emitting component 41 generates a laser beam, which shines horizontally forward after passing through the protective lens 40. The laser beam is arranged parallel to the bottom of the second cylinder 16. When preset and debugging the capture position, the laser beam can be used to quickly calibrate the horizontal position, effectively improving the accuracy of the capture positioning. The working status of the laser emitting component 41 can also be controlled by the controller inside the control box 24, and can be flexibly adjusted according to the needs.

[0045] Working principle: First, when using a multi-angle dynamic posture capture device to capture the posture of athletes in sports events, the support frame 2, column 1, support rod 5, load-bearing frame 9, and support column 10 work together to support the capture camera 11, ensuring that the capture camera 11 is aligned with the event location. By controlling the operation of the capture camera 11, the full-body posture of the athlete can be captured. Furthermore, through the operation of the servo motor 13 and in cooperation with the support column 10, the angle of the capture camera 11 can be adjusted, facilitating multi-angle capture of the athlete's posture. Controlling the operation of the electric push rod 26 adjusts the position of the support block 28. When the support block 28 moves within the through groove 27, it drives the sliding cylinder 12 to move. As the sliding cylinder 12 moves, it is connected to the connecting block 29. In coordination, the first cylinder 15 will move, and after the first cylinder 15 moves to the predetermined position, the electromagnet 25 will be controlled to work to generate a strong magnet, which, in conjunction with the support column 10, can position the sliding cylinder 12, and thus position the first cylinder 15. Adjusting the position of the first cylinder 15 can achieve full-body or close-up capture of the athlete's posture. The capture camera 11 can capture the athlete's posture and can accurately capture close-up shots of specific parts of the athlete's body, and the captured image will not be obstructed or interfered with by other parts of the athlete's body. By coordinating multiple capture cameras 11, it is possible to capture the athlete's overall movement posture comprehensively, or to capture specific close-up shots of different parts of the athlete's body. This is achieved by controlling the power motor 2. The operation of the second cylinder 16 will cause the threaded rod 23 to rotate. The rotation of the threaded rod 23 will adjust the position of the threaded cylinder 20. The movement of the threaded cylinder 20, via the load-bearing block 19, will adjust the position of the second cylinder 16. By adjusting the position of the second cylinder 16, it can be positioned to capture images of different parts of the athlete. The first plane mirror 17 and the second plane mirror 18 form a periscope optical path, enabling precise close-up captures of specific parts of the athlete's body. This effectively avoids image obstruction and visual interference from other body parts, resulting in clear local imaging and accurate capture. Furthermore, the plane mirrors allow for optical path reversal, enabling the main body of the camera 11 to be located away from the sports area, with only the front viewfinder close to the track or activity area. This does not occupy the sports field or interfere with the athlete's movement. This system is ideal for competitive sports and training, eliminating safety hazards associated with equipment deployment. The viewfinder can be positioned at any horizontal height, such as ankle, knee, waist, or shoulder, capturing images from a level perspective without perspective distortion, accurately reproducing body movements and postures. This facilitates subsequent motion analysis and technical correction. When deployed with multiple sets of 11 capture cameras, it can capture the athlete's overall posture from all angles, and also capture independent close-up shots of different body parts such as the lower limbs, torso, and upper limbs. This achieves multi-dimensional, comprehensive posture information acquisition. The system is simple in design, easy to install and debug, and has low deployment costs. It can also be discreetly installed, minimizing distraction from athletes, and captures natural and realistic movement states, significantly improving the effectiveness of motion posture capture data.When the threaded cylinder 20 moves, it drives the guide block 30 to move. The guide block 30, in conjunction with the guide rod 21, guides the threaded cylinder 20, ensuring its smooth movement and guaranteeing effective close-up shots of athletes. The movement of the guide block 30 also drives the strip plate 31 to move synchronously. The upward movement of the guide block 30 drives the compression block 32 to move, compressing the air inside the compression groove 33. This compressed air enters the one-way exhaust valve 35, which then discharges the compressed air. When the guide block 30 returns to its original position, and the strip plate 31 drives the compression block 32 to return to its original position, the one-way air intake valve 34 draws in outside air. During the compression of the air inside the compression groove 33, the compressed air flows into the one-way air intake valve... After exhaust valve 35, compressed air flows through the telescopic hose to exhaust heads 36 and 37. These exhaust heads direct the airflow to the corresponding surfaces of plane mirrors 17 and 18, effectively cleaning them and preventing impurities from affecting the capture effect. Control button 42 controls the laser emitting component 41, which generates a laser beam that passes through the protective lens 40 and projects horizontally forward. The laser beam is parallel to the bottom of cylinder 16. When setting the capture position, the laser beam can quickly calibrate the horizontal position, effectively improving the accuracy of the capture positioning.
