[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0039] Example 1
[0040] like Figure 1-5As shown, a video balance tester according to an embodiment of the present invention includes a base 1, a control box 2, an electric adjustment mechanism 3, and a manual adjustment mechanism 4. The control box 2 is mounted on one side of the top of the base 1, the electric adjustment mechanism 3 is mounted on the other side of the top of the base 1, and the manual adjustment mechanism 4 is mounted inside the base 1. A power strip and a printer can also be placed on the base 1. The power strip is used to power the video balance tester. The printer is electrically connected to the video balance tester and is used to print a test result report. The upper plane of the base 1 is 70 cm above the ground, and the height of the base 1 + the bottom mobile frame from the ground is not less than 150 cm.
[0041] The control box 2 is provided with a data transmitter 201, an image sensor 202, a video processor 203 and a data storage device 204 in sequence, and a display screen 205 is installed on the outside of the control box 2;
[0042] The control box 2 is composed of a data transmitter 201, an image sensor 202, a video processor 203, a data storage device 204, and a display screen 205. The image information collected by the camera 3022 is transmitted through the data transmitter 201, and the digital image is gray-scaled, edge detected, and contour coordinate reconstructed through the image sensor 202 and the video processor 203. The processed data is then stored in the data storage device 204 and displayed on the display screen 205. This allows the body's balance function to be evaluated in still standing, various postures, and in motion by recording changes in human posture and fixed body landmarks during motion.
[0043] The electric adjustment mechanism 3 is composed of an adjustment component 301 and a camera component 302 mounted on the adjustment component 301;
[0044] The adjustment assembly 301 includes two pillars 3011 symmetrically connected to the top of the bottom shell 1. A mounting plate 3012 is fixedly connected to the top between the two pillars 3011. A servo motor 3013 is fixedly mounted on the top of the mounting plate 3012. A threaded shaft 3014 is mounted on the output shaft of the servo motor 3013. The bottom of the threaded shaft 3014 movably penetrates the bottom shell 1 and extends into the interior of the bottom shell 1. A threaded sleeve 3015 is threadedly mounted on the surface of the threaded shaft 3014. The camera assembly 302 is mounted on the side of the threaded sleeve 3015.
[0045] The adjustment assembly 301 is composed of a support 3011, a mounting plate 3012, a servo motor 3013, a threaded shaft 3014, and a threaded sleeve 3015, and can electrically adjust the height of the camera 3022.
[0046] The manual adjustment mechanism 4 includes a rotating rod 401 rotatably mounted on the side of the bottom shell 1. The end of the rotating rod 401 close to the threaded shaft 3014 is fixedly connected to a first bevel gear 402. The surface of the threaded shaft 3014 is fixedly connected to a second bevel gear 403 that meshes with the first bevel gear 402.
[0047] The manual adjustment mechanism 4 is composed of a rotating rod 401 , a first bevel gear 402 and a second bevel gear 403 , and can manually adjust the height of the camera 3022 .
[0048] By adopting the above technical solution, the existing detection method has been changed. The video balance tester uses modern single-lens multi-focus technology to record the changes in human posture and the changes in fixed body landmark targets during movement. It can evaluate the balance function of the human body when standing still, in various postures, and in motion. In addition, the height of the camera can be adjusted manually or electrically during actual use, thus greatly improving the applicability of this video balance tester.
[0049] Among them, Figure 1 As shown, a protective shed is fixedly connected to the top of the control box 2. By adopting the above technical solution, the control box 2 is protected;
[0050] Among them, Figure 1-3 As shown, the adjustment assembly 301 further includes two sliding sleeves 3016 slidably disposed on the two pillars 3011. The side of the sliding sleeve 3016 close to the threaded sleeve 3015 is fixedly connected to the side of the threaded sleeve 3015. By adopting the above technical solution, the threaded sleeve 3015 is limited, thereby increasing the stability of the threaded sleeve 3015 in its upward and downward movement.
[0051] Among them, Figure 1-4 As shown, the camera assembly 302 is composed of a mounting frame 3021 and a camera 3022 mounted on the mounting frame 3021. The mounting frame 3021 is fixedly mounted on the side of the threaded sleeve 3015. The camera 3022 is rotatably connected to the mounting frame 3021 via a damping shaft 3023. By adopting the above technical solution, the angle of the camera 3022 can be rotated as needed, thereby increasing the monitoring range of the camera 3022.
[0052] Among them, Figure 1 As shown, both sides of the bottom of the bottom shell 1 are fixedly mounted with symmetrically arranged moving wheels, and the moving wheels are set as universal wheels. By adopting the above technical solution, the convenience of moving the video balance detector is increased;
[0053] Among them, Figure 5As shown, the bottom of the threaded shaft 3014 is rotatably mounted on the bottom of the inner wall of the bottom shell 1 through a ball bearing. By adopting the above technical solution, the rotation stability of the threaded shaft 3014 is increased.
[0054] Among them, Figure 5 As shown, a rotating handle is fixedly mounted on one end of the rotating rod 401 away from the first bevel gear 402, and a matching grip is provided on the rotating handle. By adopting the above technical solution, the convenience of rotating the rotating rod 401 is increased, thereby improving the practicality of the video balance tester.
[0055] Among them, Figure 5 As shown, the manual adjustment mechanism 4 also includes a limiting sleeve 404 mounted on the surface of the rotating rod 401. The upper and lower ends of the limiting sleeve 404 are fixedly connected to the inner wall of the bottom shell 1 through the mounting rod. By adopting the above technical solution, the rotating rod 401 is limited, thereby increasing the stability of the rotation of the rotating rod 401.
[0056] It is worth noting that the camera 3022 can use an automatic tracking camera of model ADT1806D to improve the performance of the camera 3022 in acquiring images.
[0057] Example 2
[0058] like Figure 1-5 As shown, the video balance detector provided in this embodiment is different from that in embodiment 1 in that it also includes a trolley 5, which includes a support plate 502 installed on the bottom of the bottom shell 1, a base plate 501 fixedly installed on the bottom of the support plate 502 through a support rod 504, and a self-locking universal wheel 503 fixedly installed on the bottom of the base plate 501. In order to facilitate the placement of some equipment such as a printer on the upper part of the base plate 501, the base plate 501 is arranged parallel to the support plate 502, and there is a gap between the base plate 501 and the support plate 502.
[0059] In addition, the multiple target points set on the subject are generally close to the chest and abdomen height. By setting up the trolley 5, the camera 3022 can better capture the changes in the target points.
[0060] Example 3
[0061] like Figure 1-6 As shown, the method for using a video balance detector provided by the present invention includes the following specific steps:
[0062] S1, using the camera 3022 to record changes in human posture and changes in fixed body landmarks during movement, and save them in the data storage 204;
[0063] S2. The data stored in the data memory 204 is transmitted through the data transmitter 201, and grayscale conversion, edge detection, contour coordinate reconstruction and other operations are performed on the transmitted digital image through the image sensor 202 and the video processor 203. The processed data is then stored in the data memory 204.
[0064] S3, the processed data is displayed on the display screen 205 via the data transmitter 201;
[0065] S4. Through a sequence program, the various balance parameters of the human body in static standing, various postures and movement are analyzed. The staff will evaluate the balance function of the subjects in the three postures based on clinical experience.
[0066] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.
[0067] In actual application, the image information collected by the camera 3022 is transmitted via the data transmitter 201, and the digital image is subjected to grayscale conversion, edge detection, contour coordinate reconstruction, and other operations via the image sensor 202 and the video processor 203. The processed data is then stored in the data memory 204 and displayed on the display screen 205. This allows for the assessment of a person's balance function in static standing, various postures, and motion by recording changes in body posture and fixed landmark targets during motion. The servo motor 3013 drives the threaded shaft 3014 to rotate, thereby enabling the threaded sleeve 3015 to move up and down under the action of the threads of the threaded sleeve 3015, thereby adjusting the height of the camera 3022. Furthermore, by rotating the rotating rod 401, the threaded shaft 3014 can also be rotated under the action of the first bevel gear 402 and the second bevel gear 403. This allows for automatic and manual height adjustment of the camera 3022, thereby increasing the monitoring range and improving the practicality of the video balance tester.
[0068] The above specific embodiments will allow those skilled in the art to easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific embodiments. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to implement different technical solutions.
