Description

Technical Field

[0001] The invention relates to the technical field of spine measurement, in particular to an external infrared locator for a mobile phone used for measuring scoliosis. Background Art

[0002] Scoliosis is a common spinal deformity, which is usually manifested as lateral curvature of the spine accompanied by rotation and other morphological changes. This deformity not only affects the appearance of the spine, but also has a significant impact on body posture, respiratory and cardiopulmonary function, athletic ability, quality of life and future health risks.

[0003] By regularly measuring the spine using a scoliosis measuring device, the presence of scoliosis can be detected in the early stages of the disease, and early diagnosis helps to take appropriate intervention measures, such as physical therapy or wearing a brace, to prevent the worsening of the scoliosis, especially in children and adolescents. Early intervention can effectively prevent the development of scoliosis and avoid the need for surgical treatment in the future.

[0004] The traditional method of measuring scoliosis mainly relies on X-ray imaging technology. Although X-rays can provide clear spinal images and accurately measure the curvature angle of the spine, they have significant disadvantages. First, X-ray imaging involves radiation exposure, and long-term and frequent use may pose potential health risks to patients, especially adolescents and children. Second, X-ray imaging equipment is expensive, bulky, and complex to operate. It can usually only be measured in hospitals or professional clinics, limiting its popular use in homes or communities.

[0005] In recent years, with the advancement of optical technology and computer vision technology, non-invasive spinal measurement methods have gradually attracted attention. These methods usually use infrared cameras to capture image data of the human body surface, combined with computer algorithms to generate a three-dimensional model of the spine and calculate its curvature angle.

[0006] However, when using existing non-invasive spine measurement devices, the user will turn his back to the measurement device during measurement, so the user cannot directly see his back or intuitively perceive the relative position between himself and the measurement device. Due to the lack of real-time visual feedback, the user will experience positional deviation, incorrect posture or fail to maintain the optimal measurement distance when standing. Position deviation will cause the image data captured by the infrared camera to be distorted or incomplete, thereby affecting the accurate identification of spinal morphology. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides an external infrared locator for mobile phones for measuring scoliosis, which solves the problem in the prior art that the user turns his back to the measuring device during measurement, so that the user may experience position deviation, incorrect posture or fail to maintain the optimal measurement distance, thereby affecting the accurate identification of spinal morphology.

[0021] Preferably, the control system comprises:

[0022] An image processor; the image processor is used to receive the real-time video stream of the positioning camera, the infrared image captured by the infrared camera, and the distance measured by the ranging module, and process the image and video stream;

[0023] An image analyzer, the image analyzer is used to analyze the image and video stream processed by the image processor, generate a three-dimensional model of the user's spine, and calculate the curvature angle of the spine;

[0024] The controller is used to control the speaker to sound a voice to remind the user to start the measurement before the measurement, and to control the speaker to sound a voice to remind the user to end the measurement after the image analyzer obtains the result. The positioning camera is a wide-angle camera, which is used to capture the user's full body outline and display it in real time on the screen of the mobile terminal.

[0025] Preferably, the wireless transmission module includes a Bluetooth module and a WiFi module, which are used to transmit the three-dimensional model of the user's spine and the curvature angle of the spine analyzed by the image analyzer to an application program of the mobile terminal.

[0026] Preferably, the application in the mobile terminal is used to receive and display a real-time video stream from a positioning camera; based on the measurement data of the infrared rangefinder, the user is guided to stand at a distance of 1.5 to 2 meters from the infrared camera, and the figure outline in the application is used to assist the user in adjusting the posture; the measurement is started after the user's position is determined, and after the measurement is completed, the three-dimensional model of the spine generated by the image analyzer is displayed, and the curvature angle of the spine is automatically displayed.

[0027] Working principle: When in use, first take out the device, then loosen knob 1 to unfold the legs, and after unfolding, reverse the opening angle of the legs of the rotating part to fix them, then take out the slide rod and tighten the connecting column into the sleeve, then insert the slide rod into the socket in the middle of the support plate, and finally clamp the cover shell in the groove on the top surface of the support, and insert the card plate on the outside of the plug plate. At this time, the recessed parts and raised parts on the card plate and the plug plate will open and close with each other. At this time, the arrangement of the device can be completed, and when the height of the shell needs to be adjusted, turn knob 2 to make it away from the slide rod. At this time, the support can be pulled out to drive the slide rod to slide inside the support plate, and finally reverse knob 2 to make it press against the slide rod. , the position of the shell can be fixed. When the adjustment is completed, turn on the device, then turn on the Bluetooth or wireless module of the mobile phone, enter the application at this time, use the Bluetooth or wireless module of the mobile phone to connect with the Bluetooth module or WiFi module in the wireless transmission module, and the application can obtain the field of view of the positioning camera, and the outline of the person will be displayed on the application. Then the user moves in front of the device and faces away from it, and aligns his position with the outline of the person displayed in the application. At this time, the infrared rangefinder measures the distance between the user and the infrared camera and displays it on the application. The application will adjust the distance according to the distance measurement data. According to the instructions, the user can stand at a distance of 1.5 to 2 meters from the infrared camera according to the prompts. When the user's body is outside the outline of the person on the application for a long time, the controller will control the speaker to make a sound to remind the user to calibrate his own position. When the user's posture is not right, the controller can also remind the user to calibrate his own position. After the position calibration is completed, click the "Start Measurement" button in the application, and the controller will control the speaker to make a prompt sound to remind the user that the measurement is about to start. At this time, the application will display a countdown to prompt the user to stay still. After the countdown ends, the infrared camera starts to capture the infrared image of the user's back. When the back measurement is completed, the controller drives the speaker to remind the user to turn around so that the side of the body faces the infrared camera. In this process, the positioning camera continues to capture the user's real-time video stream. The image processor receives and processes the data and then passes it to the image analyzer. The image analyzer can generate a three-dimensional model of the user's spine with the processed data and calculate the curvature angle of the spine. Then the controller transmits the analysis results to the application in the mobile phone through the wireless transmission module. Then the controller drives the speaker to issue a "measurement end" reminder. At this time, the user can see the measurement results of his own spine on the application.

[0028] The present invention provides a mobile phone external infrared locator for scoliosis measurement.

[0029] Beneficial effects:

[0030] 1. The present invention can provide the relative position between the user and the infrared camera when the user faces away from the device through the positioning camera, so as to guide the user to face the infrared camera, thereby avoiding the phenomenon of inaccurate measurement results caused by user position deviation, thereby improving the accuracy and success rate of detection.

[0031] 2. The present invention installs infrared rangefinders on both sides of the shell, so when the user adjusts his own position, the distance between the user and the infrared camera can be monitored, and the user can be placed at a certain distance from the infrared camera to avoid the user's body being too close to the camera, resulting in the body being outside the character outline on the application program. Therefore, it can assist in positioning and help the user adjust his own position.

[0032] 3. The present invention installs the shell on the support, and uses a sliding rod and a connecting column to connect the support and the support plate. After use, the device can be disassembled, thereby achieving the purpose of breaking the whole into parts, which is beneficial to the carrying of the device and improves the convenience of transfer.

[0033] 4. The present invention installs an inverted U-shaped card plate on the shell and an insert plate on the support, and the card plate and the insert plate are respectively provided with a protrusion and a recessed portion. Therefore, when the support and the shell are assembled, the shell will be located in the groove on the top surface of the support plate, and the insert rod will enter the interior of the card plate to make the protrusion and the recessed portion engage with each other, thereby improving the connection strength between the shell and the support after assembly, thereby avoiding the risk of the shell falling and improving the safety of equipment use.

[0034] 5. The present invention installs knob 2 on the support plate and opens a socket in the middle of the support plate to provide installation and movement space for the slide bar.

[0048] Please see attached Figure 1 A speaker 6 is also installed inside the housing 1, and the speaker 6 is connected to the control system.

[0049] The loudspeaker 6 can provide voice prompts to the user during use, reminding the user to start or end measurement. At the same time, when the user corrects his or her own position, the real-time video stream captured by the positioning camera 3 and the relative position of the character outline on the application can be used to remind the user how to move. Therefore, the purpose of helping the user to correct his or her own position is achieved, thereby improving the efficiency of position correction and the user's experience. When the back measurement is completed, the controller drives the loudspeaker to remind the user to turn around so that the side of the body faces the infrared camera, thereby achieving three-dimensional measurement of the spine.

[0050] Please see attached Figure 1-Figure 4 The housing 1 is provided with a support 7 at the bottom, a groove 13 is provided on the support 7, and the housing 1 is located in the groove 13. A plug plate 12 is fixed to one side of the top surface of the support 7, and a clamping plate 11 is fixed to the bottom of one side of the outer wall of the housing 1. The clamping plate 11 is arranged in an inverted U shape, and the plug plate 12 is located in the clamping plate 11. A recess is provided on one side of the plug plate 12, and a protrusion is provided on the inner wall of the clamping plate 11, and the recess and the protrusion are engaged with each other.

Therefore, when the plug plate 12 is located inside the card plate 11, the recessed portion and the protruding portion will bite into each other, thereby improving the stability of the shell 1 on the support 7.

[0052] Please see attached Figure 1-Figure 5The bottom surface of the support 7 is provided with a support plate 8, and a plurality of legs 9 are hinged at the bottom of the support plate 8, and a knob 10 is provided at the hinge to lock the legs 9. A sleeve 19 is installed on the bottom surface of the support 7, and a connecting column 14 is movably connected in the sleeve 19, and a slide bar 15 is installed at the bottom of the connecting column 14. A baffle 18 is installed on the outer wall of the slide bar 15 near the connecting column 14, and the baffle 18 contacts the support plate 8. The slide bar 15 passes through the support plate 8, and a plug hole 16 is opened in the middle of the support plate 8. The cross sections of the slide bar 15 and the plug hole 16 are both set to be square, and a knob 2 17 is connected to one side of the support plate 8, and the knob 2 17 is against the outer wall of the slide bar 15.

[0053] By turning knob 10, the multiple legs 9 can be opened, and then the angle between the legs 9 and the support plate 8 can be fixed by reversing the knob 10. The connecting column 14 is tightened in the sleeve 19 by the rotating plug rod, and then the slide bar 15 is inserted into the support plate 8, and finally the shell 1 is plugged into the support 7. At this time, the legs 9 can be used to support the support 7 and the shell 1, and by loosening knob 2 17, the support 7 can be pulled out to drive the slide bar 15 to slide in the socket 16 on the support plate 8, and finally the knob 2 17 is reversed to make it press against the slide bar 15, so that the position of the shell 1 can be fixed, so that the purpose of adjusting the height of the infrared camera 2 can be achieved, and then the spine of people of different heights can be measured, thereby improving the applicability of the device.

[0054] Please see attached Figure 6-Figure 7 The control system includes: an image processor; the image processor is used to receive the real-time video stream of the positioning camera 3, the infrared image captured by the infrared camera 2, and the distance measured by the ranging module 5, and process the image and video stream; an image analyzer, the image analyzer is used to analyze the image and video stream processed by the image processor, generate a three-dimensional model of the user's spine, and calculate the bending angle of the spine; a controller is used to control the speaker 6 to sound a reminder to the user to start the measurement before the measurement, and after the image analyzer obtains the result, control the speaker 6 to sound a reminder to the user to end the measurement, and the positioning camera 3 is a wide-angle camera, which is used to capture the user's full body outline and display it on the screen of the mobile terminal in real time, and the ranging module 5 is an infrared rangefinder.

[0055] The image processor can receive the real-time video stream of the positioning camera 3 and the infrared image captured by the infrared camera 2, and perform preliminary processing on these images and video streams, including image enhancement, denoising and feature point extraction. The image analyzer further generates a three-dimensional model of the user's spine based on the processed image and video stream, and calculates the curvature angle of the spine. The image analyzer generates accurate spine morphology and curvature data by integrating and analyzing the image data. The controller can control the speaker 6 to make a sound before the measurement to remind the user that the measurement is about to begin. At the same time, after the image analyzer obtains the result, the controller controls the speaker 6 to make a sound to remind the user that the measurement is over. At the same time, by setting the positioning camera 3 as a wide-angle camera, the real-time video stream can obtain a larger field of view, which is conducive to capturing the user's position information, and then capturing the user's full body outline, and displaying it in real time on the screen of the application in the mobile terminal, ensuring that the user can maintain a correct standing posture and position during the measurement process. At the same time, the distance measuring module 5 is an infrared rangefinder, which can measure the distance between the user and the infrared camera 2 in real time, ensuring that the user is in the best measurement position.

[0056] Please see attached Figure 6-Figure 8 The wireless transmission module includes a Bluetooth module and a WiFi module, which are used to transmit the three-dimensional model of the user's spine and the curvature angle of the spine analyzed by the image analyzer to the application of the mobile terminal. The application in the mobile terminal is used to receive and display the real-time video stream from the positioning camera 3; according to the measurement data of the infrared rangefinder, guide the user to stand at a distance of 1.5 to 2 meters from the infrared camera 2, and use the figure contour line in the application to assist the user in adjusting the posture; start the measurement after the user's position is determined, and display the three-dimensional model of the spine generated by the image analyzer after the end, and automatically display the curvature angle of the spine.

[0057] Since the wireless transmission module includes a Bluetooth module and a WiFi module, the mobile terminal can use Bluetooth and WiFi to connect to the measuring device, and can transmit the user's spine three-dimensional model and the spine bending angle to the application of the mobile terminal. At the same time, the application in the mobile terminal can receive and display the real-time video stream from the ordinary camera, and can guide the user to stand in the correct position by comparing the character outline on the application with the user's position in the video stream; at the same time, according to the measurement data of the infrared rangefinder, the application can prompt the user to adjust the posture in real time to ensure that the user is in the correct position and maintains the correct posture.
