Abstract
Description
Technical Field
[0001] The present invention relates to the field of fitness equipment, and in particular to a fitness movement information interaction device and a data generation method. Background Art
[0002] Fitness resistance training exercises are those in which people resist resistance to perform resistance training, such as squats, deadlifts, bench presses, etc.
[0003] Whether the force application actions of fitness athletes are normal affects different fitness effects: for example, muscle building training requires slow concentric and eccentric force application, while explosive power training requires rapid force application. Traditional video recording and sensor data are independent, lacking the ability of spatio-temporal synchronous analysis; lacking real-time data visualization means, it is difficult to perform immediate correction of action details.
[0004] Fitness athletes cannot know the magnitude of the force used at each stage of the whole process during training, and can only perceptually recognize the magnitude of their own force application and the speed of the action. They cannot accurately and digitally represent the force application at each stage of their own action process and the corresponding action acceleration, and thus cannot quantify their training process, and cannot effectively guide fitness exercises and improve training effects. Summary of the Invention
[0005] Object of the Invention: In order to overcome the deficiencies of the background art, the first object of the present invention is to disclose a fitness movement information interaction device; The second object is to disclose a data generation method based on the above fitness movement information interaction device.
[0006] Technical Solution: The fitness movement information interaction device disclosed by the present invention includes: An information measurement device, which includes an acceleration sensor, a data processing unit, a wireless transmission module, and a power supply module; An operation terminal, which includes a video shooting unit and a data processing unit; the operation terminal and the information measurement device keep the time consistent through a time synchronization protocol; the information measurement device acquires the acceleration information of the position to be measured at a preset frequency, and transmits it to the operation terminal in combination with the time stamp information of the acquisition frequency. The operation terminal synchronously records a motion video, and generates acceleration information and video information superimposed video data in combination with the same time stamp information; Furthermore, it further includes a server for collecting the superimposed video data for downloading and sharing.
[0007] Furthermore, the information measurement device is a detachable assembly device.
[0008] Correspondingly, a fitness movement information data generation method is also disclosed, including the following steps: S1. Obtain the acceleration data of the position to be measured at a preset frequency, and record the time stamp of collecting the acceleration data at the same time; S2. Shoot a video of the movement process, and record the video time stamp corresponding to the acceleration time stamp at the same time; S3. Establish a spatio-temporal synchronization coordinate system, and generate a data video with the superposition of the acceleration-time curve and the video-time curve. Further, the position to be measured is the human body movement position and / or the instrument movement position.
[0009] Further, the spatio-temporal synchronization coordinate system is realized by dynamically matching the video frame time stamp and the acceleration data time stamp.
[0010] Further, the generated data video is uploaded to the server for downloading and sharing.
[0011] Beneficial effects: Compared with the prior art, the present invention breaks through the limitations of resistance exercise monitoring, obtains the acceleration fitness data of the moving human body or instrument in real time, combines the biomechanical acceleration data with visual information to realize data visualization, which is convenient for athletes to analyze the force details of each action after training, refine the corresponding frame of action and its force acceleration, and provide a more three-dimensional training evaluation. Users can watch their actions and corresponding accelerations frame by frame to understand their force details; an action video and acceleration template library of excellent athletes can be established, which is convenient for users to download and compare to guide their fitness exercises, effectively improving the fitness effect and fitness experience. Brief Description of the Drawings
[0012] Figure 1 It is a schematic diagram of the device module of the present invention; Figure 2 It is a flowchart of the control method of the present invention. Detailed Embodiment
[0013] The technical solutions of the present invention will be further described below with reference to the drawings and embodiments.
[0014] During resistance exercise, such as deadlift, the athlete needs to perform each action in each stage of knee joint movement, hip joint movement, back movement, etc. throughout the process. The force exerted by the athlete in each action conforms to the following formula: F = mg + ma Where m is the resistance mass, g is the acceleration due to gravity, and a is the instantaneous acceleration of the instrument.
[0015] That is to say, the magnitude of the force exerted in each movement of fitness exercise is linearly related to the instantaneous acceleration of the equipment at that time. If the instantaneous acceleration of each movement at each stage throughout the resistance exercise can be visually observed, the magnitude of the force exerted in each movement can be effectively determined. At the same time, if the movement video can be viewed synchronously, it is possible to intuitively discover whether one's movements are standard and whether the acceleration of the corresponding movement force is reasonable, thereby effectively guiding athletes to refine the details of their movements and improving the effect of resistance training.
[0016] As Figure 1 shown, this embodiment discloses a fitness movement information interaction device, including: an information measurement device, an operation terminal, and a server.
[0017] The information measurement device includes an acceleration sensor, a data processing unit, a wireless transmission module, and a power module; the information measurement device is a detachable assembly device.
[0018] The operation terminal includes a video shooting unit and a data processing unit; the operation terminal and the information measurement device maintain the same time through a time synchronization protocol.
[0019] The information measurement device obtains the acceleration information of the mobile end at a preset frequency and transmits it to the operation terminal in combination with the timestamp information of the acquisition frequency. The operation terminal synchronously records the movement video and generates acceleration information and video information to superimpose the video data in combination with the same timestamp information.
[0020] The server is used to collect the superimposed video data for downloading and sharing.
[0021] A method for generating fitness movement information data can be implemented based on the above-mentioned fitness movement information interaction device. As Figure 2 shown, it includes the following steps: Assemble the information measurement device to the position to be measured, which can be the position of the human body movement and / or the position of the equipment movement. When the user starts the fitness exercise and turns on the switch, the device establishes a connection with the operation terminal wirelessly (such as Bluetooth), and at the same time performs time synchronization through a clock synchronization protocol (such as the NTP protocol) to ensure that the time of the hardware acquisition device is the same as that of the operation terminal.
[0022] The acceleration sensor obtains the acceleration data of the position to be measured at a preset frequency (0.01s). The data processing unit simultaneously records the timestamp of the acquired acceleration data, and the information is packaged and transmitted to the operation terminal.
[0023] The operation terminal shoots the video of the movement process and simultaneously records the video timestamp corresponding to the acceleration timestamp.
[0024] A spatio-temporal synchronization coordinate system is established through the dynamic matching of the video frame timestamps and the acceleration data timestamps. The video uses the frame timestamps during the shooting process as the video time axis, and the acceleration data uses the collected timestamps as the data time axis. By unifying the video time axis and the data time axis, the two types of data can be combined, and the acceleration of the corresponding instrument for each frame can be superimposed on the video to generate a visualization training data video report with the acceleration-time curve superimposed on the video.
[0025] On the operating system, when viewing the video, the display frequency of the acceleration can be selected. For example, if 0.1 second display is selected, then the display frequency (0.1 second display) / the acquisition frequency (such as 0.01 second acquisition) is calculated, and the multiple is 10. According to this, the average value of every 10 accelerations collected is calculated and used as the displayed acceleration. The user can view their own actions and the corresponding accelerations frame by frame to understand the details of their force application.
[0026] The generated data video is uploaded to the server for downloading and sharing. Users can analyze their own data videos and download the data videos of excellent athletes as templates to compare with their own training data for effective guidance.
